c91d924e3a ACPICA: Fix for hang on GPE method invocation
Fixes problem where the new method argument count validation mechanism
will enter an infinite loop when a GPE method is dispatched.
Problem fixed be removing the obsolete code that passes GPE block
information to the notify handler via the control method parameter pointer.

f3454ae810 ACPICA: Add argument count checking to control method invocation via acpi_evaluate_object
Error if too few arguments, warning if too many. This applies
only to external programmatic control method execution, not
method-to-method calls within the AML.

ebb12db51f Freezer: Introduce PF_FREEZER_NOSIG
The freezer currently attempts to distinguish kernel threads from
user space tasks by checking if their mm pointer is unset and it
does not send fake signals to kernel threads.  However, there are
kernel threads, mostly related to networking, that behave like
user space tasks and may want to be sent a fake signal to be frozen.

Introduce the new process flag PF_FREEZER_NOSIG that will be set
by default for all kernel threads and make the freezer only send
fake signals to the tasks having PF_FREEZER_NOSIG unset.  Provide
the set_freezable_with_signal() function to be called by the kernel
threads that want to be sent a fake signal for freezing.

This patch should not change the freezer's observable behavior.

2fe2de5f6c ACPI PM: acpi_pm_device_sleep_state() cleanup
Get rid of a superfluous acpi_pm_device_sleep_state() parameter.  The
only legitimate value of that parameter must be derived from the first
parameter, which is what all the callers already do.  (However, this
does not address the fact that ACPI still doesn't set up those flags.)

e38e8a0743 Make GPE disable more robust
Implemented another change for the GPE disable. We now perform a
read-change-write of the enable register instead of simply writing out the
cached enable mask. This will prevent inadvertent enabling of GPEs if a rogue
GPE is received during initialization (before GPE handlers are installed.)

63f5abb095 ide: remove action argument in ide_do_drive_cmd
ide_do_drive_cmd is called only with ide_preempt action argument. So
we can remove the action argument in ide_do_drive_cmd and ide_action_t
typedef.

This patch also includes two minor cleanups: 1) ide_do_drive_cmd
always succeeds so we don't need the return value; 2) the callers use
blk_rq_init before ide_do_drive_cmd so there is no need to initialize
rq->errors.

1357214461 ide: remove ->mmio flag from ide_hwif_t
Since scc_pata host driver no longer uses IDE PCI layer / ide_dma_setup()
and all other ->mmio users set also IDE_HFLAG_MMIO host flag we can safely
remove ->mmio flag.

There should be no functional changes caused by this patch.

9a410e79b5 ide: remove IDE_TFLAG_NO_SELECT_MASK taskfile flag
Always call SELECT_MASK(..., 0) in ide_tf_load() (needs to be done
to match ide_set_irq(..., 1)) and then remove IDE_TFLAG_NO_SELECT_MASK
taskfile flag.

This change should only affect hpt366 and icside host drivers since
->maskproc(..., 0) for sgiioc4 is equivalent to ide_set_irq(..., 1).
