This restores the previous behavior of stopping all child devices before
removing any of them. The current SR-IOV design, where removing the PF
also drops references on all the VFs, depends on having the VFs continue

This reverts commit 433efd2247.
When we remove an SR-IOV device, we have this call chain:
driver .remove() method
pci_disable_sriov()
sriov_disable()
virtfn_remove()
pci_get_domain_bus_and_slot()
sriov_disable() is only called for PFs, not for VFs. When it's called
for a PF, it loops through all the VFs and calls virtfn_remove() for
each. But we stop and remove VFs before PFs, so by the time we get
to virtfn_remove(), the VFs have already been stopped and deleted
from the device list. Now pci_get_domain_bus_and_slot(), which uses
bus_find_device() and relies on that device list, doesn't find the
VFs, so the VF references aren't released correctly.

* 'drm-fixes-3.6' of git://people.freedesktop.org/~agd5f/linux:
drm/radeon: Prevent leak of scratch register on resume from suspend
Cards typically have 5-7 scratch registers; one of these is reserved for
rdev->rptr_save_reg. Unfortunately the reservation is done in function
r100_cp_init, which is called by all drivers except r600 - and this
function is also invoked on resume from suspend. After several resumes,
no scratch registers are free and graphics acceleration is disabled.
Dmesg then reports either:
*ERROR* radeon: cp failed to get scratch reg (-22).
*ERROR* radeon: cp isn't working(-22).
radeon 0000:01:00.0: failed initializing CP (-22).
or:
*ERROR* radeon: failed to get scratch reg (-22).
*ERROR* radeon: failed testing IB on GFX ring (-22).
*ERROR* ib ring test failed (-22).
The chain of calls on boot for all except r600 is:
radeon_init -> ... -> (rXXX_init) -> rXXX_startup -> r100_cp_init
The chain of calls on resume for all except r600 is:
rXXX_resume -> rXXX_startup -> r100_cp_init.
R600 correctly allocates rptr_save_reg in r600_init (ie once only, not
in resume). However moving the code into the init functions for all
drivers means touching 4 drivers. So instead, this patch just adds a
test in r100_cp_init to avoid reallocating on resume. As the rdev
structure is allocated via kzalloc in radeon_driver_load_kms, and zero
is not a valid registerid, zero safely implies not-yet-allocated.

The early generations with this trackpad used the separate mouse
interface to produce button events. With the introduction of the
button pads, this information was moved to the trackpad interface,
leaving the mouse interface unused. The driver is still setting up
both interfaces, which has not caused any problems - until now.
It turns out that without the CONFIG_USB_EHCI_TT_NEWSCHED option, the
driver may return an ENOSPC upon bt_urb submission, resulting in a
failure to open the device. This happens everytime on the MacBookPro
Retina (and likely on other mid-2012 models), but earlier MacBook
models seem to work fine.
This patch skips the bt_urb setup for TYPE2 devices, which arguably
should have been done in the first place.

Merge tag 'v3.6-rc5' into for-linus
Sync with mainline so that I can revert an input patch that came in through
another subsystem tree.
powernowk8_target() runs off a per-cpu work item and if the
cpufreq_policy->cpu is different from the current one, it migrates the
kworker to the target CPU by manipulating current->cpus_allowed. The
function migrates the kworker back to the original CPU but this is
still broken. Workqueue concurrency management requires the kworkers
to stay on the same CPU and powernowk8_target() ends up triggerring
BUG_ON(rq != this_rq()) in try_to_wake_up_local() if it contends on
fidvid_mutex and sleeps.
It is unclear why this bug is being reported now. Duncan says it
appeared to be a regression of 3.6-rc1 and couldn't reproduce it on
3.5. Bisection seemed to point to 63d95a91 "workqueue: use @pool
instead of @gcwq or @cpu where applicable" which is an non-functional
change. Given that the reproduce case sometimes took upto days to
trigger, it's easy to be misled while bisecting. Maybe something made
contention on fidvid_mutex more likely? I don't know.
This patch fixes the bug by using work_on_cpu() instead if @pol->cpu
isn't the same as the current one. The code assumes that
cpufreq_policy->cpu is kept online by the caller, which Rafael tells
me is the case.
stable: ed48ece27c ("workqueue: reimplement work_on_cpu() using
system_wq") should be applied before this; otherwise, the
behavior could be horrible.

[HID: Fix race condition between driver core and ll-driver] introduced
new locking around probe/remove functions that prevents any report/reply
from hardware to reach driver until it returned from probe.
As such, the ask-reply way to checking picoLCD firmware version during
probe is bound to timeout and let probe fail.
Drop the check to let driver successfully probe again (until locking issues
are resolved allowing to reinstate the check).

`parse_insn()` is dereferencing the user-space pointer `insn->data`

`insn_rw_emulate_bits()` is used to emulate the `INSN_READ` and
`INSN_WRITE` comedi instructions for subdevices that don't have an
`insn_read()` or `insn_write()` handler but do have an `insn_bits()`
handler.
The function fills in a temporary `struct comedi_insn` called `new_insn`
to pass to the subdevice's `insn_bits()` handler. In doing so, it sets
the `new_insn.data` pointer to point to a temporary data array. This
results in a warning from "sparse" because the `data` pointer in `struct
comedi_insn` has the `__user` tag. The subdevice's `insn_bits()`
handler ignores it anyway as it gets passed a pointer to the temporary
data array in a separate parameter. Don't bother setting
`new_insn.data`; just leave it set to `NULL` (done by an earlier
`memset()`).

For the COMEDI_DEVCONFIG ioctl, the user application may embed a pointer
to firmware data within a designated element (or two elements for 64-bit
pointers) of the `options[]` array in the `struct comedi_devconfig`.
`do_devconfig_ioctl()` calls `comedi_aux_data()` to extract the pointer
value. It needs to be treated as a `__user` pointer so the firmware
data can be copied into kernel memory, so cast the result of
`comedi_aux_data()` to avoid a "sparse" warning. This is not ideal but
`comedi_aux_data()` is called elsewhere in a wholly kernel memory
context so we can't just change its return type to include the `__user`
tag.

This does not work for auto-configured PCI devices due to the

Rename 'chanlist_saver' to 'user_chanlist' to avoid confusion that
it's actually a __user *.
The chanlist pointer in comedi_cmd is still a user space pointer when
the comedi_cmd is copied with copy_from_user() in do_cmd_ioctl() and
do_cmdtest_ioctl(). This pointer needs to be cast when it is saved in
user_chanlist in order to preserve its address space.
The copy_from_user() call to copy the chanlist to the kernel space
comedi_command requires the second parameter to be a __user pointer.
Use the correctly cast user_chanlist instead of cmd->chanlist.
Before the comedi_cmd is copied back to user space, the saved
user_chanlist pointer is restored. Cast the user_chanlist again so
that the address space matches the comedi_cmd.

The 'chanlist' is passed to the kernel from user space with the
COMEDI_CMD and COMEDI_CMDTEST ioctls. The do_cmd_ioctl() and
do_cmdtest_ioctl() functions in comedi_fops.c copy this data
to/from user space to kernel space correctly.
Unfortunately, this data is copied back into a struct comedi_cmd
so when the cmd is passed down to the drivers they still see the
pointer as __user data. This results is a number of sparse errors
such as:
warning: dereference of noderef expression
warning: incorrect type in argument 2 (different address spaces)

warning: incorrect type in assignment (different address spaces)
expected unsigned int *ai_chanlist

The two functions in comedi_fops are the only ones that need the
__user tag. Remove the tag so that all the drivers see the chanlist
pointer in the correct address space.

It isn't always necessary to update the metadata when spares are
removed as the presence-or-not of a spare isn't really important to
the integrity of an array.
Also activating a spare doesn't always require updating the metadata
as the update on 'recovery-completed' is usually sufficient.
However the introduction of 'replacement' devices have made these
transitions sometimes more important. For example the 'Replacement'
flag isn't cleared until the original device is removed, so we need
to ensure a metadata update after that 'spare' is removed.
So set MD_CHANGE_DEVS whenever a spare is activated or removed, to
complement the current situation where it is set when a spare is added
or a device is failed (or a number of other less common situations).
This is suitable for -stable as out-of-data metadata could lead
to data corruption.
This is only relevant for 3.3 and later 9when 'replacement' as
introduced.

Signed-off-by: NeilBrown <neilb@suse.de>
When a replacement device becomes active, we mark the device that it
replaces as 'faulty' so that it can subsequently get removed.
However 'calc_degraded' only pays attention to the primary device, not
the replacement, so the array appears to become degraded, which is
wrong.
So teach 'calc_degraded' to consider any replacement if a primary
device is faulty.
This is suitable for -stable as an incorrect 'degraded' value can
confuse md and could lead to data corruption.
This is only relevant for 3.3 and later.

Later it was also used for host bridge aperture lists, which was fine until

address offset"). That commit added offset information, so we needed a
struct pci_host_bridge_window that was separate from struct
pci_bus_resource.

Just like for the in-tree early console debug port driver, the
hypervisor - when using a debug port based console - also needs to be
told about controller resets, so it can suppress using and then
re-initialize the debug port accordingly.
Other than the in-tree driver, the hypervisor driver actually cares
about doing this only for the device where the debug is port actually
in use, i.e. it needs to be told the coordinates of the device being
reset (quite obviously, leveraging the addition done for that would
likely benefit the in-tree driver too).

If a command status of CMD_PROTOCOL_ERR is received, this
information should be conveyed to the SCSI mid layer, not
dropped on the floor. CMD_PROTOCOL_ERR may be received
from the Smart Array for any commands destined for an external
RAID controller such as a P2000, or commands destined for tape
drives or CD/DVD-ROM drives, if for instance a cable is
disconnected. This mostly affects multipath configurations, as
disconnecting a cable on a non-multipath configuration is not
going to do anything good regardless of whether CMD_PROTOCOL_ERR
is handled correctly or not. Not handling CMD_PROTOCOL_ERR
correctly in a multipath configaration involving external RAID
controllers may cause data corruption, so this is quite a serious
bug. This bug should not normally cause a problem for direct
attached disk storage.

only affects tape drives and CD and DVD ROM drives in the cciss

cable, so it is not a very likely scenario (which would explain
why the bug has gone undetected for the last 10 years.)

Here's a driver for the Vizzini USB to serial device.
It looks to be copied from cdc-acm, and probably can be cleaned up a lot
more. Also, there's some odd "try to grab another interface" that is
probably wrong. And, if this really is a cdc-acm device, it probably
should just be a quirk of the cdc-acm device, but I can't figure that
out, and people have been using this driver for a long time now. So
merge it to let people use their hardware and clean it up over time.

On some platforms, bootloaders are known to do some interesting RTC
programming. Without going into the obscurities as to why this may be
the case, suffice it to say the the driver should not make any
assumptions about the state of the RTC when the driver loads. In
particular, the driver probe should be sure that all interrupts are
disabled until otherwise programmed.
This was discovered when finding bursty I2C traffic every second on
Overo platforms. This I2C overhead was keeping the SoC from hitting
deep power states. The cause was found to be the RTC firing every
second on the I2C-connected TWL PMIC.
Special thanks to Felipe Balbi for suggesting to look for a rogue driver
as the source of the I2C traffic rather than the I2C driver itself.
Special thanks to Steve Sakoman for helping track down the source of the
continuous RTC interrups on the Overo boards.

Fix a serious but uncommon bug in nbd which occurs when there is heavy
I/O going to the nbd device while, at the same time, a failure (server,
network) or manual disconnect of the nbd connection occurs.
There is a small window between the time that the nbd_thread is stopped
and the socket is shutdown where requests can continue to be queued to
nbd's internal waiting_queue. When this happens, those requests are
never completed or freed.
The fix is to clear the waiting_queue on shutdown of the nbd device, in
the same way that the nbd request queue (queue_head) is already being
cleared.

Add support for the ad7091r 12 bit ADC to the ad7476 driver. Although the
ad7091r is not really related to any of the other devices supported by this
driver, luckily for us there are not so many ways (which are not totally insane)
how sampling a single channel ADC via SPI can be implemented and support for the
ad7091r can be added to the driver with just a few adjustments.
The ad7091r requires an external "conversion start" pulse to start a sample
conversion. After the conversion has finished the result can be read via SPI. We
depend on a IIO trigger to generate this signal, as a result only sampling in
buffered mode and not in manual mode is available.

This patch adds support for the AD5755, AD5755-1, AD5757, AD5735, AD5737 16 and
14 bit quad-channel DACs. The AD5757/AD5737 only have current outputs, but
for the AD5755/AD5757 each of the outputs can be configured to either be a
voltage or a current output. We only allow to configure this at device probe
time since usually this needs to match the external circuitry and should not be
changed on the fly.

The datasheet name is defined in the IIO driver.
On the other hand, the adc_channel_label is configured in
the platform side.
If the datasheet name is not matched with any adc_channel_label,
the iio_channel_get() should be returned as error for preventing
invalid channel data access.
This can be handled either way.
(a) checking null data when using it : in the xxx_read_raw()
or
(b) error returns when the channel is requested : this patch
The IIO consumer can't use the channel with invalid channel spec.
Therefore case (b) is more reasonable.

commit c4e00daaa9
("driver-core: extend dev_printk() to pass structured data")
changed __dev_printk and broke dynamic-debug's ability to control the
dynamic prefix of dev_dbg(dev,..).
commit af7f2158fd
("drivers-core: make structured logging play nice with dynamic-debug")
made a minimal correction.
The current dynamic debug code uses up to 3 recursion levels via %pV.
This can consume quite a bit of stack. Directly call printk_emit to
reduce the recursion depth.
These changes include:
dev_dbg:
o Create and use function create_syslog_header to format the syslog
header for printk_emit uses.
o Call create_syslog_header and neaten __dev_printk
o Make __dev_printk static not global
o Remove include header declaration of __dev_printk
o Remove now unused EXPORT_SYMBOL() of __dev_printk
o Whitespace neatening

This patch fixes the following kernel panic invoked by uninitialized fields
in the chip initialization for the 1G bnx2 iSCSI offload.
One of the bits in the chip initialization is being used by the latest
firmware to control overflow packets. When this control bit gets enabled
erroneously, it would ultimately result in a bad packet placement which would
cause the bnx2 driver to dereference a NULL ptr in the placement handler.
This can happen under certain stress I/O environment under the Linux
iSCSI offload operation.
This change only affects Broadcom's 5709 chipset.

softsynth_read() reads a character at a time from the init string;
when it finds the null terminator it sets the initialized flag but
then repeats the last character.
Additionally, if the read() buffer is not big enough for the init
string, the next read() will start reading from the beginning again.
So the caller may never progress to reading anything else.
Replace the simple initialized flag with the current position in
the init string, carried over between calls. Switch to reading
real data once this reaches the null terminator.
(This assumes that the length of the init string can't change, which
seems to be the case. Really, the string and position belong together
in a per-file private struct.)

The majority of the DMI checks in efifb are for cases where the bootloader
has provided invalid information. However, on some machines the overrides
may do more harm than good due to configuration differences between machines
with the same machine identifier. It turns out that it's possible for the
bootloader to get the correct information on GOP-based systems, but we
can't guarantee that the kernel's being booted with one that's been updated
to do so. Add support for a capabilities flag that can be set by the
bootloader, and skip the DMI checks in that case. Additionally, set this
flag in the UEFI stub code.

The PCI-6534 needs three firmware files loading to work with the driver.
That is currently done by passing the firmware data using the
`COMEDI_DEVCONFIG` ioctl that uses the comedi `attach()` hook in the
driver. This doesn't work for auto-configured PCI devices (which also
currently use the `attach()` hook in this driver, but doesn't have the
firmware-loading options set in the `struct comedi_devconfig *`
parameter).
Change the driver to request the firmware files using
`request_firmware()`, ignoring any firmware-loading options set in the
`struct comedi_devconfig`.
The PCI-6534 has a main FPGA which needs to be loaded first, and two
"scarabs". Scarab A is loaded with firmware to support digital input
mode, and scarab B is loaded with firmware to support digital output
mode.
I don't think the order of loading the scarab firmwares matters as long
as they are loaded with the correct firmware files. This update loads
scarab B first, whereas the original code loaded scarab A first. The
firmware files are loaded in the following order:
A) main FPGA: "ni6534a.bin" (FW_PCI_6534_MAIN)
B) scarab B: "niscrb02.bin" (FW_PCI_6534_SCARAB_DO)
C) scarab A: "niscrb01.bin" (FW_PCI_6534_SCARAB_DI)
The required firmware files can be found in the
"comedi-nonfree-firmware" tar-ball at
<http://www.comedi.org/download/comedi-nonfree-firmware-2007.06.22.tar.gz>.

Read unit address is done for all devices during online processing to read

Some older storage hardware does not provide the capability to read unit
address configuration.
This leads to a loop trying to read unit address configuration every 30
seconds. The device is still operational but logs are flooded with error
messages.
Fix the loop by recognizing a command reject saying that the suborder

If a pathgroup is established we need to set system characteristics for

====================
This is a batch of fixes intended for the 3.6 stream.
Arend van Spriel sends a simple thinko fix to correct a constant,
preventing the setting of an invalid power level.
Colin Ian King gives us a simple allocation failure check to avoid a
NULL pointer dereference.
Felix Fietkau sends another ath9k tx power patch, this time disabling a
feature that has been reported to cause rx problems.
Hante Meuleman provides a pair of endian fixes for brcmfmac.
Larry Finger offers an rtlwifi fix that avoids a system lockup related
to loading the wrong firmware for RTL8188CE devices.
These have been in linux-next for a few days and I think they should be
included in the final 3.6 kernel if possible.

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.
Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

The managed clk functions are currently only available when the generic clk
lookup framework is build. But the managed clk functions are merely wrappers
around clk_get and clk_put and do not depend on any specifics of the generic
lookup functions and there are still quite a few custom implementations of the
clk API. So make the managed functions available whenever the clk API is
implemented.
The patch also removes the custom implementation of devm_clk_get for the

Use kzalloc() rather than kmalloc() for initializing the iio_channel structure.
This patch enables the iio_dev and iio_chan_spec are set to NULL.
This may prevent the page fault problem because the pointer of iio_chan_spec
is initialized as NULL.
The iio_chan_spec is updated only in case that the IIO map has
specific channel label.
When the map has no ADC channel label, then the value of iio_chan_spec
remains as invalid pointer.
To prevent this problem, the pointer should be initialized as NULL.

Currently IIO uses a decimal fixed point representations for real type numbers.
This patch introduces a new representation for rational type numbers. The number
will be expressed by specifying a numerator and denominator. For converting a
raw value to a processed value multiply it by the numerator and divide it by the
denominator.
The reasoning for introducing this new type is that for a lot of devices the
scale can be represented easily by a fractional number, but it is not possible
to represent it as fixed point number without rounding. E.g. for a simple DAC
the scale is often the reference voltage divided by the number of possible
values (Usually 2**n_bits - 1). Each driver currently implements the conversion
of this fraction to a fixed point number on its own.
Also when it comes to the in-kernel interface this allows to directly use the
fractional factors to convert a raw value to a processed value. This should on
one hand require less instructions and on the other hand increase the
precision.

After the recent cleanups the buffer support is just a single 23 line function.
This does not really justify a file on its own, so move it to the main driver
file. And with only one source file left the header file containing the device
state struct becomes superflousious so move the content of the header
file to the main driver source file as well.

Slightly rework the reference voltage handling for the ad7476 driver. Now the only
way to specify a external reference voltage is to use the regulator API,
previously it was possible to use either platform_data or the regulator API. The
new way is more consistent with what other drivers do.
Also do not ignore errors when requesting the regulator, since this will cope
very poorly with e.g. deferred probing.

Here are a number of USB patches, a bit more than I normally like this
late in the -rc series, but given people's vacations (myself included),
and the kernel summit, it seems to have happened this way.
All are tiny, but they add up. A number of gadget and xhci fixes, and a
few new device ids. All have been tested in linux-next.

When using the commands below to write some data to a virtio-scsi LUN of the
QEMU guest(32-bit) with 1G physical memory(qemu -m 1024), the qemu will crash.
# sudo mkfs.ext4 /dev/sdb (/dev/sdb is the virtio-scsi LUN.)
# sudo mount /dev/sdb /mnt
# dd if=/dev/zero of=/mnt/file bs=1M count=1024
In current implementation, sg_set_buf is called to add buffers to sg list which
is put into the virtqueue eventually. But if there are some HighMem pages in
table->sgl you can not get virtual address by sg_virt. So, sg_virt(sg_elem) may
return NULL value. This will cause QEMU exit when virtqueue_map_sg is called
in QEMU because an invalid GPA is passed by virtqueue.
Two solutions are discussed here:
http://lkml.indiana.edu/hypermail/linux/kernel/1207.3/00675.html
Finally, value assignment approach was adopted because:
Value assignment creates a well-formed scatterlist, because the termination
marker in source sg_list has been set in blk_rq_map_sg(). The last entry of the
source sg_list is just copied to the the last entry in destination list. Note
that, for now, virtio_ring does not care about the form of the scatterlist and
simply processes the first out_num + in_num consecutive elements of the sg[]
array.
I have tested the patch on my workstation. QEMU would not crash any more.

The driver reconfigures DRAM size register to 8M (regardless what the
actual size was) once the init has been completed, overwriting the
correct value written during the early init. As a result if the driver
is unloaded and reloaded, the user will be limited to 8M video memory
and may lose some of the available video modes.

Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
On embedded systems without a BIOS, the DRAM sizing register is 0 after
the boot, and the driver thinks we have only 1 MB video memory. On such
cases, use the PCI window size for the initial size. This information
is needed only to create the I/O mapping - the driver will later detect
and configure the memory size correctly. Limit the size to 16 MB as it
should be sufficient for all supported video modes.

integer overflow issues around MTT table") so that memory registration
of up to 8TB (log_num_mtt=31) finally works.
It fixes integer overflows in a few mlx4_table_yyy routines in icm.c
by using a u64 intermediate variable, and int/uint issues that caused
table indexes to become nagive by setting some variables to be u32
instead of int. These problems cause crashes when a user attempted to

Hi Greg,
Here's seven patches for 3.7.
The first four fix an issue with Set Address command timeouts. It turns out
that Set Address timeouts can trigger a warning that was put in to avoid a NULL
pointer dereference. This patchset fixes the underlying cause of the NULL
pointer that was papered over by the warning. They should be applied to stable,
but I'm a bit nervous about the size, so I'd rather they go into 3.7, rather
than trying to stuff them into a late 3.6-rc.
The other three patches are various trivial fixes.

According to xHCI spec section 4.6.1.1 and section 4.6.1.2,
after aborting a command on the command ring, xHC will
generate a command completion event with its completion
code set to Command Ring Stopped at least. If a command is
currently executing at the time of aborting a command, xHC
also generate a command completion event with its completion
code set to Command Abort. When the command ring is stopped,
software may remove, add, or rearrage Command Descriptors.
To cancel a command, software will initialize a command
descriptor for the cancel command, and add it into a
cancel_cmd_list of xhci. When the command ring is stopped,
software will find the command trbs described by command
descriptors in cancel_cmd_list and modify it to No Op
command. If software can't find the matched trbs, we can
think it had been finished.

Software have to abort command ring and cancel command
when a command is failed or hang. Otherwise, the command
ring will hang up and can't handle the others. An example
of a command that may hang is the Address Device Command,
because waiting for a SET_ADDRESS request to be acknowledged
by a USB device is outside of the xHC's ability to control.
To cancel a command, software will initialize a command
descriptor for the cancel command, and add it into a
cancel_cmd_list of xhci.

Commit 0090def("ACPI: Add interface to register/unregister device
to/from power resources") used resource_lock to protect the devices list
that relies on power resource. It caused a mutex dead lock, as below
acpi_power_on ---> lock resource_lock
__acpi_power_on
acpi_power_on_device
acpi_power_get_inferred_state
acpi_power_get_list_state ---> lock resource_lock
This patch adds a new mutex "devices_lock" to protect the devices list
and calls acpi_power_on_device in acpi_power_on, instead of
__acpi_power_on, after the resource_lock is released.

It turns out that there are ACPI BIOSes defining device objects with
_PSx and without either _PSC or _PRx. For devices corresponding to
those ACPI objetcs __acpi_bus_get_power() returns ACPI_STATE_UNKNOWN
and their initial power states are regarded as unknown as a result.
If such a device is a parent of another power-manageable device, the
child cannot be put into a low-power state through ACPI, because
__acpi_bus_set_power() refuses to change power states of devices
whose parents' power states are unknown.
To work around this problem, observe that the ACPI power state of
a device cannot be higher-power (lower-number) than the power state
of its parent. Thus, if the device's _PSC method or the
configuration of its power resources indicates that the device is
in D0, the device's parent has to be in D0 as well. Consequently,
if the parent's power state is unknown when we've just learned that
its child's power state is D0, we can safely set the parent's
power.state field to ACPI_STATE_D0.

Study of Apple's binary driver revealed that the GMUX_READ_PORT should
be written between calls to gmux_index_wait_ready and
gmux_index_wait_complete (i.e., the new index protocol must be
followed). If this is not done correctly, the indexed
gmux device only partially accepts writes which lead to problems
concerning GPU switching. Special thanks to Seth Forshee who helped
greatly with identifying unnecessary changes.
