Commit 28c2103 added new state ACPI_STATE_D3_COLD, so the device power
states array must be expanded by one also.v2: Use ACPI_D_STATE_COUNT instead of number 5 for the array size.

The firmware on some machine will report duplicated hardware error
source ID in HEST. This is considered a firmware bug. To provide
better warning message, this patch adds duplicated hardware error
source ID detecting and corresponding printk.This patch fixes #37412 on kernel bugzilla:

All ACPICA locks are allocated by the same function,
acpi_os_create_lock(), with the help of a local variable called
"lock". Thus, when lockdep is enabled, it uses "lock" as the
name of all those locks and regards them as instances of the same
lock, which causes it to report possible locking problems with them
when there aren't any.To work around this problem, define acpi_os_create_lock() as a macro
and make it pass its argument to spin_lock_init(), so that lockdep
uses it as the name of the new lock. Define this macron in a
Linux-specific file, to minimize the resulting modifications of
the OS-independent ACPICA parts.This change is based on an earlier patch from Andrea Righi and it
addresses a regression from 2.6.39 tracked as

i915_driver_load adds a write-combining MTRR region for the GTT
aperture to improve memory speeds through the aperture. If
i915_driver_load fails after this, it would not have cleaned up the
MTRR. This shouldn't cause any problems, except for consuming an MTRR
register. Still, it's best to clean up completely in the failure path,
which is easily done by calling mtrr_del if the mtrr was successfully
allocated.i915_driver_load calls i915_gem_load which register
i915_gem_inactive_shrink. If i915_driver_load fails after calling
i915_gem_load, the shrinker will be left registered. When called, it
will access freed memory and crash. The fix is to unregister the shrinker in the
failure path using code duplicated from i915_driver_unload.i915_driver_load also has some incorrect gotos in the error cleanup
paths:* After failing to initialize the GTT (which cannot happen, btw,
intel_gtt_get returns a fixed (non-NULL) value), it tries to
free the uninitialized WC IO mapping. Fixed this by changing the
target from out_iomapfree to out_rmmapSigned-off-by: Keith Packard

Just compiling pseries in the kernel causes it to override
memory_block_size_bytes() regardless of what is the runtime
platform.This cleans up the implementation of that function, fixing
a bug or two while at it, so that it's harmless (and potentially
useful) for other platforms. Without this, bugs in that code
would trigger a WARN_ON() in drivers/base/memory.c when
booting some different platforms.If/when we have another platform supporting memory hotplug we
might want to either move that out to a generic place or
make it a ppc_md. callback.Signed-off-by: Benjamin Herrenschmidt

That file harkens back to the days of the big 2.4 -> 2.6 version jump,

and Jesper Juhl points out that it talks about kernel versions 2.6 and

Patch 2e711c04dbbf7a7732a3f7073b1fc285d12b369d
(PM: Remove sysdev suspend, resume and shutdown operations)
deleted sysdev_suspend(), which was being relied on to call
check_wakeup_irqs() in suspend. If check_wakeup_irqs() is not
called, wake interrupts that are pending when suspend is
entered may be lost. It also breaks IRQCHIP_MASK_ON_SUSPEND,
which is handled in check_wakeup_irqs().This patch adds a call to check_wakeup_irqs() in syscore_suspend(),
similar to what was deleted in sysdev_suspend().Signed-off-by: Colin Cross
