The Lifebook S6420 is the ICH9M-based follow-up to the S6410. The application panel
contains the following keys: lock, mobility center, eco, info.
Whilst key 4 might be more appropriate for help then key 2, I've done things the
S6410 way. I can confirm that backlight control is functional, and that the lock key
activates the Gnome screensaver as expected.

Reformat acpi.debug_layer and acpi.debug_level documentation so it's
more readable, add some clues about how to figure out the mask bits that
enable a specific ACPI_DEBUG_PRINT statement, and include some useful
examples.
Move the list of masks to Documentation/acpi/debug.txt (these are
copies of the authoritative values in acoutput.h and acpi_drivers.h).

When CONFIG_ACPI_DEBUG=y, the default acpi_dbg_layer and acpi_dbg_level
values built into the ACPI CA have some debug output enabled. We'd
rather be quiet unless the user actually specified the acpi.debug_level
argument.
This enables distros to ship with CONFIG_ACPI_DEBUG=y without
inundating users with debug output.

Some of the component definitions that were previous scattered around
the drivers conflict with each other. That doesn't hurt anything
except that setting one bit in the debug_layer mask would turn on
debugging in two different modules. This patch fixes the conflicts.

Could fix a bug in a hotplug add scenario.
WARNING: drivers/misc/fujitsu-laptop.o(.text+0xbde): Section mismatch in reference from the function acpi_fujitsu_add() to the variable .init.data:fujitsu_dmi_table
The function acpi_fujitsu_add() references
the variable __initdata fujitsu_dmi_table.
This is often because acpi_fujitsu_add lacks a __initdata
annotation or the annotation of fujitsu_dmi_table is wrong.

Remove CONFIG_ACPI_EC. It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".
Per section 6.5.4 of the ACPI 3.0b specification,
OSPM must make Embedded Controller operation regions, accessed
via the Embedded Controllers described in ECDT, available before
executing any control method.
The ECDT table is optional, but if it is present, the above text
means that the EC it describes is a required part of the ACPI
subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.

Remove CONFIG_ACPI_POWER. It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".
The interfaces under CONFIG_ACPI_POWER (acpi_device_sleep_wake(),
acpi_power_transition(), etc) are called unconditionally from the
ACPI core, so we already depend on it always being present.

Introduce a new flag showing whether the event has an event handler/method.
For all the GPEs and Fixed Events,
1. ACPI_EVENT_FLAG_HANDLE is cleared, it's an "invalid" ACPI event.
2. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_DISABLE are set,
it's "disabled".
3. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_ENABLE are set,
it's "enabled".
4. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_WAKE_ENABLE are set,
it's "wake_enabled".
Among other things, this prevents incorrect reporting of ACPI events
as being "invalid" when it's really just (temporarily) "disabled".

Impact: fix incorrect locking triggered during hotplug-intense stress-tests
While migrating the the CB_IRQSAFE_UNLOCKED timers during a cpu-offline,
we queue them on the cb_pending list, so that they won't go
stale.
Thus, when the callbacks of the timers run from the softirq context,
they could run into potential deadlocks, since these callbacks

Fix this by emulating hardirq context while running these callbacks from
the hrtimer softirq.

Impact: nohz powersavings and wakeup regression
commit fb02fbc14d17837b4b7b02dbb36142c16a7bf208 (NOHZ: restart tick
device from irq_enter()) causes a serious wakeup regression.
While the patch is correct it does not take into account that spurious
wakeups happen on x86. A fix for this issue is available, but we just
revert to the .27 behaviour and let long running softirqs screw
themself.
Disable it for now.

Impact: avoid spurious ksoftirqd wakeups
The tick idle check which is called from irq_enter() was run before
the call to __irq_enter() which did not set the in_interrupt() bits in
preempt_count. That way the raise of a softirq woke up softirqd for
nothing as the softirq was handled on return from interrupt.
Call __irq_enter() before calling into the tick idle check code.

Some functions that may be called from this handler require that
interrupts are disabled. Also, combining IRQF_DISABLED and
IRQF_SHARED does not reliably disable interrupts in a handler, so
remove IRQF_SHARED from the irq flags (this irq is not shared anyway).

In hpet_next_event() we check that the value we just wrote to
HPET_Tn_CMP(timer) has reached the chip. Currently, we're checking that
the value we wrote to HPET_Tn_CMP(timer) is in HPET_T0_CMP, which, if
timer is anything other than timer 0, is likely to fail.

under rq->lock
Impact: fix hang/crash on ia64 under high load
This is ugly, but the simplest patch by far.
Unlike other similar routines, account_group_exec_runtime() could be
called "implicitly" from within scheduler after exit_notify(). This
means we can race with the parent doing release_task(), we can't just
check ->signal != NULL.
Change __exit_signal() to do spin_unlock_wait(&task_rq(tsk)->lock)
before __cleanup_signal() to make sure ->signal can't be freed under
task_rq(tsk)->lock. Note that task_rq_unlock_wait() doesn't care
about the case when tsk changes cpu/rq under us, this should be OK.
Thanks to Ingo who nacked my previous buggy patch.

Impact: removal of unnecessary looping
The lockless part of the ring buffer allows for reentry into the code
from interrupts. A timestamp is taken, a test is preformed and if it
detects that an interrupt occurred that did tracing, it tries again.
The problem arises if the timestamp code itself causes a trace.
The detection will detect this and loop again. The difference between
this and an interrupt doing tracing, is that this will fail every time,
and cause an infinite loop.
Currently, we test if the loop happens 1000 times, and if so, it will
produce a warning and disable the ring buffer.
The problem with this approach is that it makes it difficult to perform
some types of tracing (tracing the timestamp code itself).
Each trace entry has a delta timestamp from the previous entry.
If a trace entry is reserved but and interrupt occurs and traces before
the previous entry is commited, the delta timestamp for that entry will
be zero. This actually makes sense in terms of tracing, because the
interrupt entry happened before the preempted entry was commited, so
one may consider the two happening at the same time. The order is
still preserved in the buffer.
With this idea, instead of trying to get a new timestamp if an interrupt
made it in between the timestamp and the test, the entry could simply
make the delta zero and continue. This will prevent interrupts or
tracers in the timer code from causing the above loop.

Impact: fix for bug on resize
This patch addresses the bug found here:
http://bugzilla.kernel.org/show_bug.cgi?id=11996
When ftrace converted to the new unified trace buffer, the resizing of
the buffer was not protected as much as it was originally. If tracing
is performed while the resize occurs, then the buffer can be corrupted.
This patch disables all ftrace buffer modifications before a resize
takes place.

When we are about to add a new item to a transaction in recovery, we need
to check that it is valid first. Currently we just assert that header
magic number matches, but in production systems that is not present and we
add a corrupted transaction to the list to be processed. This results in a
kernel oops later when processing the corrupted transaction.
Instead, if we detect a corrupted transaction, abort recovery and leave
the user to clean up the mess that has occurred.

When there is no memory left in the system, xfs_buf_get_noaddr()
can fail. If this happens at mount time during xlog_alloc_log()
we fail to catch the error and oops.
Catch the error from xfs_buf_get_noaddr(), and allow other memory
allocations to fail and catch those errors too. Report the error
to the console and fail the mount with ENOMEM.
Tested by manually injecting errors into xfs_buf_get_noaddr() and

When we create a directory, we reserve a number of blocks for the maximum
possible expansion of of the directory due to various btree splits,
freespace allocation, etc. Unfortunately, each allocation is not reflected
in the total number of blocks still available to the transaction, so the
maximal reservation is used over and over again.
This leads to problems where an allocation group has only enough blocks
for *some* of the allocations required for the directory modification.
After the first N allocations, the remaining blocks in the allocation
group drops below the total reservation, and subsequent allocations fail
because the allocator will not allow the allocation to proceed if the AG
does not have the enough blocks available for the entire allocation total.
This results in an ENOSPC occurring after an allocation has already
occurred. This results in aborting the directory operation (leaving the
directory in an inconsistent state) and cancelling a dirty transaction,
which results in a filesystem shutdown.
Avoid the problem by reflecting the number of blocks allocated in any
directory expansion in the total number of blocks available to the
modification in progress. This prevents a directory modification from
being aborted part way through with an ENOSPC.

It's possible to have outstanding xfs_ioend_t's queued when the file size
is zero. This can happen in the direct I/O path when a direct I/O write
fails due to ENOSPC. In this case the xfs_ioend_t will still be queued (ie
xfs_end_io_direct() does not know that the I/O failed so can't force the
xfs_ioend_t to be flushed synchronously).
When we truncate a file on unlink we don't know to wait for these
xfs_ioend_ts and we can have a use-after-free situation if the inode is
reclaimed before the xfs_ioend_t is finally processed.
As was suggested by Dave Chinner lets wait for all I/Os to complete when
truncating the file size to zero.

Destroying the quota stuff on unmount can access the log - ie
XFS_QM_DONE() ends up in xfs_dqunlock() which calls
xfs_trans_unlocked_item() and then xfs_log_move_tail(). By this time the
log has already been destroyed. Just move the cleanup of the quota code
earlier in xfs_unmountfs() before the call to xfs_log_unmount(). Moving
XFS_QM_DONE() up near XFS_QM_DQPURGEALL() seems like a good spot.
