For instance, if there is a Plogi pending (remote port is in Plogi state),
and the state changes to say NONE (because the port is being logged off),
then when the Plogi resp times out, do not start a retry.
This patch partially reverts an earlier patch (libfc: check for err when
recv and state is incorrect), by moving the state check back to before
checking for error. However, if the state does not match, then there is
an additional check to see if its an error ptr or a real frame before
jumping to err or out respectively.

gpn_ft_resp processing currently does not hold the discovery lock.
disc_done() thus gets called from gpn_ft_resp or from gpn_ft_parse
without the lock held. This then sets disc->pending to zero or calls
gpn_ft_req() without disc_lock held.
- Hold disc mutex during gpn_ft resp processing
- In disc_done, release the disc mutex while calling lport callback

If a command's scsi cmd pdu setup fails then we can just fail
the IO to the scsi layer. If a DATA_OUT for a R2T fails then
we will want to drop the session, because it means we got a
bad request from the target (iscsi protocol error).
This patch has us propogate the error upwards so libiscsi_tcp
or libiscsi can decide what the best action is to take. It
also fixes a bug where we could try to grab the session lock
while holding it, because if iscsi_tcp drops the session in the
pdu setup callout the session lock is held when setting up the
scsi cmd pdu.

The ERP thread is performing a task before it is executing the
corresponding down on the semaphore. The response handler of the
just started exchange config should wait for the completion by
performing a down on this semaphore. Since this semaphore is still
positive from the ERP enqueue the handler won't wait and therefore
the exchange config will always fail leaving the adapter in error.
The problem can be solved by performing the down on the semaphore
before starting an ERP task. This is the logically correct order.
Only walk the ERP loop if there is a task to perform.

So, what's happening here is that the drive is reporting a sense of
2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and
then we ask for the media event notification before checking that result
at all. The check_media_event_descriptor() call isn't getting a check
condition, but it's also reporting that the tray is closed and that
there's no media. In actuality it doesn't yet know if there's media or
not, but there's no way to express that in the media event status field.
My current thought is that if it told us the device isn't yet ready, we
should return that immediately, since there's nothing that'll tell us
any more data than that reliably:

Linux tells ICH4 users that they can (manually) invoke
"hpet=force" to enable the undocumented ICH-4M HPET.
The HPET becomes available for both clocksource and clockevents.
But as of ff69f2bba6
(acpi: fix of pmtimer overflow that make Cx states time incorrect)
the HPET may be used via clocksource for idle accounting, and
hpet=force on an ICH4 box hangs boot.
It turns out that touching the MMIO HPET withing
the ARB_DIS part of C3 will hang the hardware.
The fix is to simply move the timer access outside
the ARB_DIS region. This is a no-op on modern hardware
because ARB_DIS is no longer used.

This patch (as1231) fixes a use-after-free bug in g_file_storage. A
device's name may not be available after the device is unregistered,
even if the device structure itself is still allocated. Since
close_backing_file() prints a LUN's name for debugging, it shouldn't
be called after the LUN has been unregistered.
That whole area needed to be cleaned up; the backing files were
getting closed in a couple of different places. The patch fixes
things so that they get closed in just one place, as part of the
unbind procedure, immediately before the LUN is unregistered.

lead to a situation in which the first 188 bytes of a 192-byte
isochronous transfer are scheduled in the same uframe as an existing
interrupt transfer. The resulting schedule looks like this:
uframe 0: 188-byte isoc-OUT SSPLIT, 8-byte int-IN SSPLIT
uframe 1: 4-byte isoc-OUT SSPLIT
The SSPLITs are intermingled, causing an error in the downstream hub's
TT.

This patch (as1229) fixes a few lifetime and locking problems in the
usb-serial driver. The main symptom is that an invalid kevent is
created when the serial device is unplugged while a connection is
active.
Ports should be unregistered when device is disconnected,
not when the parent usb_serial structure is deallocated.
Each open file should hold a reference to the corresponding
port structure, and the reference should be released when
the file is closed.
serial->disc_mutex should be acquired in serial_open(), to
resolve the classic race between open and disconnect.
serial_close() doesn't need to hold both serial->disc_mutex
and port->mutex at the same time.
Release the subdriver's module reference only after releasing
all the other references, in case one of the release routines
needs to invoke some code in the subdriver module.
Replace a call to flush_scheduled_work() (which is prone to
deadlocks) with cancel_work_sync(). Also, add a call to
cancel_work_sync() in the disconnect routine.
Reduce the scope of serial->disc_mutex in serial_disconnect().
The only place it really needs to protect is where the
"disconnected" flag is set.

Fix UDMA throughput bug: tCYC averages t2CYCTYP/2, but the code
previously assumed it was the same as t2CYCTYP. (That is, it was
using just one clock edge, not both.) Move the table's type
declaration so it's adjacent to the table, making it more clear
what those numbers mean.
On one system this change increased throughput by almost 4x: UDMA/66
sometimes topped 23 MB/sec (on a drive known to do much better). On
another system it was around a 10% win (UDMA/66 up to 7+ MB/sec).
The difference might be caused by the ratio between memory and IDE
clocks. In the system with large speedup, this was exactly 2 (as a
workaround for a rev 1.1 silicon bug). The other system used a more
standard ratio of 1.63 (and rev 2.1 silicon) ... clock domain synch
might have some issues, they're not unheard-of.

There is currently only one way for userspace to say "wait for my storage
device to get ready for the modules I just loaded": to load the
scsi_wait_scan module. Expectations of userspace are that once this
module is loaded, all the (storage) devices for which the drivers
were loaded before the module load are present.
Now, there are some issues with the implementation, and the async
stuff got caught in the middle of this: The existing code only
waits for the scsy async probing to finish, but it did not take
into account at all that probing might not have begun yet.
(Russell ran into this problem on his computer and the fix works for him)
This patch fixes this more thoroughly than the previous "fix", which
had some bad side effects (namely, for kernel code that wanted to wait for
the scsi scan it would also do an async sync, which would deadlock if you did
it from async context already.. there's a report about that on lkml):
The patch makes the module first wait for all device driver probes, and then it
will wait for the scsi parallel scan to finish.

A few issues wrt DMA were uncovered when using the driver with swiotlb.
- driver should not use memory after it has been mapped
- iwl3945's RX queue management cannot use all of iwlagn because
the size of the RX buffer is different. Revert back to using
iwl3945 specific routines that map/unmap memory.
- no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single,
we can just call pci_unmap_single initially
- only map the memory area that will be used by device. this is especially
relevant to the mapping of iwl_cmd. we should not map the entire
structure because the meta data at the beginning of structure contains
the address to be used later for unmapping. If the address to be used for
unmapping is stored in mapped data it creates a problem.
- ensure that _if_ memory needs to be modified after it is mapped that we
call _sync_single_for_cpu first, and then release it back to device with
_sync_single_for_device
- we mapped the wrong length of data for host commands, with mapped length
differing with length provided to device, fix that.

When debugging TX issues it is helpful to know the seq nr of the
frame being transmitted. The seq nr is printed as part of ucode's
log informing us which frame is being processed. Having this information
printed in driver log makes it easy to match activities between driver
and firmware.
Also make possible to print TX flags directly. These are already printed
as part of entire TX command, but having it printed directly in cpu format
makes it easier to look at.

This patch fixes a build warning in mwl8.c.
(Marvell TOPDOG wireless driver)
The warning it fixes is: "large integer implicitly truncated to unsigned type."
The rx_ctrl member of the mwl8k_rx_desc struct is 8 bit (__u8 ), whereas trying
to assign it a 32 bit value (which is returned from cpu_to_le32())
causes the compiler to issue

As the sk_sleep wait queue actually lives in tfile, which may be
detached from the tun device, bad things will happen when we use
sk_sleep after detaching.
Since the tun device is the persistent data structure here (when
requested by the user), it makes much more sense to have the wait
queue live there. There is no reason to have it in tfile at all
since the only time we can wait is if we have a tun attached.
In fact we already have a wait queue in tun_struct, so we might
as well use it.

The commit c70f182940 ("tun: Fix
races between tun_net_close and free_netdev") fixed a race where
an asynchronous deletion of a tun device can hose a poll(2) on
a tun fd attached to that device.
However, this came at the cost of moving the tun wait queue into
the tun file data structure. The problem with this is that it
imposes restrictions on when and where the tun device can access
the wait queue since the tun file may change at any time due to
detaching and reattaching.
In particular, now that we need to use the wait queue on the
receive path it becomes difficult to properly synchronise this
with the detachment of the tun device.
This patch solves the original race in a different way. Since
the race is only because the underlying memory gets freed, we
can prevent it simply by ensuring that we don't do that until
all tun descriptors ever attached to the device (even if they
have since be detached because they may still be sitting in poll)
have been closed.
This is done by using reference counting the attached tun file
descriptors. The refcount in tun->sk has been reappropriated
for this purpose since it was already being used for that, albeit
from the opposite angle.
Note that we no longer zero tfile->tun since tun_get will return
NULL anyway after the refcount on tfile hits zero. Instead it
represents whether this device has ever been attached to a device.

Commit 900af0d973 (PM: Change suspend
code ordering) changed the ordering of suspend code in such a way
that the platform .prepare() callback is now executed after the
device drivers' late suspend callbacks have run. Unfortunately, this
turns out to break ARM platforms that need to talk via I2C to power
control devices during the .prepare() callback.
For this reason introduce two new platform suspend callbacks,
.prepare_late() and .wake(), that will be called just prior to
disabling non-boot CPUs and right after bringing them back on line,
respectively, and use them instead of .prepare() and .finish() for
ACPI suspend. Make the PM core execute the .prepare() and .finish()
platform suspend callbacks where they were executed previously (that
is, right after calling the regular suspend methods provided by
device drivers and right before executing their regular resume
methods, respectively).
It is not necessary to make analogous changes to the hibernation
code and data structures at the moment, because they are only used
by ACPI platforms.

Fixes guest crash 'lguest: bad read address 0x4800000 len 256'
The new per-cpu allocator ends up handing a non-linear address to
write_gdt_entry. We do __pa() on it, and hand it to the host, which
kills us.
I've long wanted to make the hypercall "LOAD_GDT_ENTRY" to match the IDT
code, but had no pressing reason until now.

Typical message: 'lguest: unhandled trap 6 at 0x418726 (0x0)'
vmlinux guests were broken by 4cd8b5e2a1
'lguest: use KVM hypercalls', which rewrites guest text from kvm hypercalls
to trap 31.
The Launcher mmaps the kernel image. The Guest executes and
immediately faults in the first text page (read-only). Then it hits a
hypercall, and we rewrite that hypercall, causing a copy-on-write.
But the Guest pagetables still refer to the old page: we fault again,
but as Host we see the hypercall already rewritten, and pass the fault
back to the Guest. The Guest hasn't set up an IDT yet, so we kill it.
This doesn't happen with bzImages: they unpack themselves and so the
text pages are already read-write.

MTD has got sysfs support in 2.6.30-rc1. But subpage size is not
exposed there - do this.
UBI utilities badly need this parameter. At the moment there is
no way to get subpage size - ioctls do not return it. And we
just got sysfs support, so we can easilly extend it with this
additional parameter.
This can be merged late in the development cycle because:
1. sysfs support has been just added - there are no users for
it so far, even.
2. UBI utilities really need this parameter, and it is better
not to delay this.

There exist laptops with Elantech touchpads where switching to absolute mode
does not happen, although writing the configuration register succeeds
without error. Reading back the register afterwards reveils that the
absolute mode bit is not set as if masked out by the touchpad firmware.
Always read back register 0x10, make sure that for hardware version 1 the
absolute mode bit is actually set and fail otherwise. This prevents the case
where the touchpad is claimed by the Elantech driver but is nonetheless not
working.

It seems that Elantech touchpad firmware version 2.34 on the Hercules eCAFÉ
suffers from a problem where bogus coordinates get reported at the beginning
of a touch action. This causes the mouse cursor or the scrolled page to
jump.
Included patch provides a workaround that discards mouse packets that are
likely to contain bogus coordinates. The workaround is activated when we
detect touchpad with fimware version 2.34.

The set_blink hook code in the LED subdriver would never manage to get
a LED to blink, and instead it would just turn it on. The consequence
of this is that the "timer" trigger would not cause the LED to blink
if given default parameters.
This problem exists since 2.6.26-rc1.
To fix it, switch the deferred LED work handling to use the
thinkpad-acpi-specific LED status (off/on/blink) directly.
This also makes the code easier to read, and to extend later.

Workaround for errata SATA#24 in sata_mv.
This errata affects WRITE_MULTI* commands when
the device multi_count produces a DRQ block size >= 4Kbytes.
We work around it here by converting such operations
into ordinary PIO_WRITEs instead.
Note that this might result in a PIO FUA write unavoidably being converted
into a non-FUA write. In practice, any system using FUA is also going to be
using DMA rather than PIO, so this shouldn't affect anyone in the real world.
