irqdomain code and to a couple of drivers that make use of it."
* tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux:
irqchip: Return -EPERM for reserved IRQs
irqdomain: document the simple domain first_irq
kernel/irq/irqdomain.c: before use 'irq_data', need check it whether valid.
irqdomain: export irq_domain_add_simple
The irqdomain core will report a log message for any attempted map call
that fails unless the error code is -EPERM. This patch changes the
Versatile irq controller drivers to use -EPERM because it is normal for
a subset of the IRQ inputs to be marked as reserved on the various
Versatile platforms.

Commit 9f29ab11dd ("ACPI / scan: do not match drivers against objects
having scan handlers") introduced a boot regression on Tony's ia64 HP
rx2600. Tony says:
"It panics with the message:
Kernel panic - not syncing: Unable to find SBA IOMMU: Try a generic or DIG kernel
[...] my problem comes from arch/ia64/hp/common/sba_iommu.c
where the code in sba_init() says:
acpi_bus_register_driver(&acpi_sba_ioc_driver);
if (!ioc_list) {
but because of this change we never managed to call ioc_init()
so ioc_list doesn't get set up, and we die."
Revert it to avoid this breakage and we'll fix the problem it attempted
to address later.

- Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no
interrupt in icoll_handle_irq() becomes insane, because 0x7f is an
valid interrupt number, the irq of gpio bank 0. That unnecessary
polling results in the driver not detecting when irq 0x7f is active
which makes the machine effectively dead lock. The fix removes the
interrupt poll loop and allows usage of gpio0 interrupt without an
infinite loop.

moves most ZTE CDMA devices from option to zte_ev. The blacklist stuff
that option does is not required with zte_ev, because it doesn't
implement any of the send_setup hooks which the blacklist suppressed.
I did not move the 2718 over because I could not find any ZTE Linux

With the introduction of ACPI scan handlers, an ACPI device object
with an ACPI scan handler attached to it must not be bound to an ACPI
driver any more. Therefore it doesn't make sense to match those
ACPI device objects against a newly registered ACPI driver in
acpi_bus_match(), so make that function return 0 if the device
object passed to it has an ACPI scan handler attached.
This also addresses a regression related to a broken ACPI table in
the BIOS, where it has defined a _ROM method under the PCI root
bridge object. This causes the video module to treat that object
as a display controller device (since only display devices are
supposed to have a _ROM method defined according to the ACPI spec).
As a result, the ACPI video driver binds to the PCI root bridge
object and overwrites the previously assigned driver_data field of
it, causing subsequent calls to acpi_get_pci_dev() to fail.

Commit 4b31e774 (Always set P-state on initialization) fixed bug
#4634 and caused the driver to always set the target P-State at
least once since the initial P-State may not be the desired one.
Commit 5a1c0228 (cpufreq: Avoid calling cpufreq driver's target()
routine if target_freq == policy->cur) caused a regression in
this behavior.
This fixes the regression by setting policy->cur based on the CPU's
target frequency rather than the CPU's current reported frequency
(which may be different). This means that the P-State will be set
initially if the CPU's target frequency is different from the
governor's target frequency.
This fixes an issue where setting the default governor to
performance wouldn't correctly enable turbo mode on all cores.

It was recently found out that GSO on 57710/57711 was broken, due to packets
being sent without a valid IP checksum.
Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this
issue, but failed to set the correct IP checksum when receiving GSO packets
via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed
to calculate IP checksum were erroneously set in the incorrect
buffer descriptor.
This patch re-enables GSO in said scenario for 57710/57711 chips.

Change the code to destroy the "last opened" rdma_cm id after making
sure we released all other objects (QP, CQs, PD, etc) associated with

Since iser accesses the IB device using the rdma_cm id, we need to
free any objects that are related to the device that is associated
with the rdma_cm id prior to destroying that id. When this isn't
done, the low level driver that created this device can be unloaded
before iser has a chance to free all the objects and a such a call may
invoke code segment which isn't valid any more and crash.

In the PF initialization, SRIOV is enabled before the PF is fully initialized.
This allows the kernel to probe the newly-exposed VFs before the PF is ready
to handle them (nested probes).
Have the probe method return the -EPROBE_DEFER value in this situation (instead
of the VF probe method retrying its initialization in a loop, and returning -EIO
on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel
itself will retry the probe after a suitable delay.

In summary, the symptom is intermittent key events lost after resume
on some machines with synaptics touchpad (seems this is synaptics _only_),
and key events loss is due to serio port reconnect after psmouse sync lost.
Removing psmouse and inserting it back during the suspend/resume process
is able to work around the issue, so the difference between psmouse_connect()
and psmouse_reconnect() is the key to the root cause of this problem.
After comparing the two different paths, synaptics driver has its own
implementation of synaptics_reconnect(), and the missing psmouse_probe()
seems significant, the patch below added psmouse_probe() to the reconnect
process, and has been verified many times that the issue could not be reliably
reproduced.
There are two PS/2 commands in psmouse_probe():
1. PSMOUSE_CMD_GETID
2. PSMOUSE_CMD_RESET_DIS
Only the PSMOUSE_CMD_GETID seems to be significant. The
PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying
several times. So we have only implemented this patch to issue
the PSMOUSE_CMD_GETID so far.

PCI serial ports moving between ttyS4 and ttyS0 when you bisect to opposite
sides of this commit, resulting in the need to constantly modify the console
setting in order to bisect across it.
Please revert, we can work on solving this for ARM platforms in a less
disruptive way.

The mxs interrupt controller does not support polling for interrupts,
but the driver still does it, which is a relict from
pre-MULTI_IRQ_HANDLER times.
The existing code assumes that 0x7f means no interrupt, but this value
is an actually valid irq number, namely gpio bank 0's irq. This results
in the driver not detecting when irq 0x7f is active which makes the
machine effectively dead lock.
This patch removes the interrupt poll loop and allows usage of gpio0
interrupt without an infinite loop.

The current radeon driver initialization routines, when using KMS, are written
so that the IRQ installation routine is called before initializing the WB buffer
and the CP rings. With some ASICs, though, the IRQ routine tries to access the
GFX_INDEX ring causing a call to RREG32 with the value of -1 in
radeon_fence_read. This, in turn causes the system to completely hang with some
cards, requiring a hard reset.
A call stack that can cause such a hang looks like this (using rv515 ASIC for the
example here):
* rv515_init (rv515.c)
* radeon_irq_kms_init (radeon_irq_kms.c)
* drm_irq_install (drm_irq.c)
* radeon_driver_irq_preinstall_kms (radeon_irq_kms.c)
* rs600_irq_process (rs600.c)
* radeon_fence_process - due to SW interrupt (radeon_fence.c)
* radeon_fence_read (radeon_fence.c)
* hang due to RREG32(-1)
The patch moves the IRQ installation to the card startup routine, after the ring
has been initialized, but before the IRQ has been set. This fixes the issue, but
requires a check to see if the IRQ is already installed, as is the case in the
system resume codepath.
I have tested the patch on three machines using the rv515, the rv770 and the
evergreen ASIC. They worked without issues.
This seems to be a known issue and has been reported on several bug tracking
sites by various distributions (see links below). Most of reports recommend
booting the system with KMS disabled and then enabling KMS by reloading the
radeon module. For some reason, this was indeed a usable workaround, however,
UMS is now deprecated and disabled by default.

If we always force the pipe A to on we can't use the hw state to
decide whether it should be on. Hence quirk the quirk.
The problem is that crtc->active tracks the state of the entire
display pipe, i.e. including planes, encoders and all. But our hw
state readout simply looks at the pipe. But with the pipe A quirk we
force-enable that (together with it's pll). To fix that mismatch we
have two options:
- Quirk the checked state to match what our sw tracking states if the
pipe A quirk is in effect.
- Improve the hw state readout to not get fooled by the pipe A quirk.
Since we already have similar state clamping in e.g. assert_pipe I've
opted for the first variant. Also note that we don't really loose any
state checking: Individual pieces of the abstract crtc pipe are
checked in the enable/disable functions with the various asssert_*
checks we have, and the hw state check code doesn't check anything if
the pipe is off anyway.
v2: Pimp commit message after discussion with Chris and only apply the
quirk for the quirk if we're checking pipe A. Otherwise we'll miss
state checking for pipe B on i830M ...
v3: Make the code comment consistent with the improved commit message,
too (Chris).

drm/i915: clear up wedged transitions
X can again get -EIO when it does not expect it. And even worse score
a SIGBUS when accessing gtt mmaps. The established ABI is that we
_only_ return an -EIO from execbuf - all other ioctls should just
work. And since the reset code moves all bos out of gpu domains and
clears out all the last_seqno/ring tracking there really shouldn't be
any reason for non-execbuf code to ever touch the hw and see an -EIO.
After some extensive discussions we've noticed that these spurios -EIO
are caused by i915_gem_wait_for_error:
http://www.mail-archive.com/intel-gfx@lists.freedesktop.org/msg20540.html
That is easy to fix by returning 0 instead of -EIO, since grabbing the
dev->struct_mutex does not yet mean that we actually want to touch the
hw. And so there is no reason at all to fail with -EIO.
But that's not the entire since, since often (at least it's easily
googleable) dmesg indicates that the reset fails and we declare the
gpu wedged. Then, quite a bit later X wakes up with the "Timed out
waiting for the gpu reset to complete" DRM_ERROR message in
wait_for_errror and brings down the desktop with an -EIO/SIGBUS.
So clearly we're missing a wakeup somewhere, since the gpu reset just
doesn't take 10 seconds to complete. And indeed we're do handle the
terminally wedged state wrong.
Fix this all up.

When GPU acceleration is disabled, drm_vblank_cleanup() will free the
vblank-related data, such as vblank_refcount, vblank_inmodeset, etc.
But we found that drm_vblank_post_modeset() may be called after the
cleanup, which use vblank_refcount and vblank_inmodeset. And this will
cause a kernel panic.
Fix this by return immediately if dev->num_crtcs is zero. This is the
same thing that drm_vblank_pre_modeset() does.

The driver's interrupt handling code is too picky in deciding whether it should
handle an interrupt or not which causes completely unneeded spurious interrupts.
Thus make sata_rcar_{ata|serr}_interrupt() *void*; add ATA status register read
to sata_rcar_ata_interrupt() to clear an unexpected ATA interrupt -- it doesn't
get cleared by writing to the SATAINTSTAT register in the interrupt mode we use.
Also, in sata_rcar_ata_interrupt() we should check SATAINTSTAT register only for
enabled interrupts and we should clear only those interrupts that we have read
as active first time around, because else we have a race and risk clearing an
interrupt that can occur between read and write of the SATAINTSTAT register
and never registering it...
