Some userspaces do not preserve unusable property. Since usable
segment has to be present according to VMX spec we can use present
property to amend userspace bug by making unusable segment always
nonpresent. vmx_segment_access_rights() already marks nonpresent segment
as unusable.

On platforms such as Cortex-A15 based OMAP5, SCU is not used, however
since much code is shared between Cortex-A9 based OMAP4 (which uses
SCU) and OMAP5, It does help to have inline functions returning error

arch/arm/mach-omap2/omap-smp.c which is common between OMAP4 and 5

The role of acpi_bus_update_power() is to update the given ACPI
device object's power.state field to reflect the current physical
state of the device (as inferred from the configuration of power
resources and _PSC, if available). For this purpose it calls
acpi_device_set_power() that should update the power resources'
reference counters and set power.state as appropriate. However,
that doesn't work if the "new" state is D1, D2 or D3hot and the
the current value of power.state means D3cold, because in that
case acpi_device_set_power() will refuse to transition the device
from D3cold to non-D0.
To address this problem, make acpi_bus_update_power() call
acpi_power_transition() directly to update the power resources'
reference counters and only use acpi_device_set_power() to put
the device into D0 if the current physical state of it cannot
be determined.

Commit 7c30ed ("cpufreq: make sure frequency transitions are serialized")
interacts poorly with systems that have a single core freqency for all
cores. On such systems we have a single policy for all cores with
several CPUs. When we do a frequency transition the governor calls the
pre and post change notifiers which causes cpufreq_notify_transition()
per CPU. Since the policy is the same for all of them all CPUs after
the first and the warnings added are generated by checking a per-policy
flag the warnings will be triggered for all cores after the first.
Fix this by allowing notifier to be called for n times. Where n is the number of
cpus in policy->cpus.

This patch changes the function to set spec->eapd_nid after the

This fixes gpu reset on my gm45 - without this patch the bsd thing is
forever stuck since the seqno updates never reach the status page.
Tbh I have no idea how this ever worked without rewriting the hws
registers after a gpu reset.
To satisfy my OCD also give the functions a bit more consistent names:
- Use status_page everywhere, also for the physical addressed one.
- Use init for the allocation part and setup for the register setup
part consistently.
Long term I'd really like to share the hw init parts completely
between gpu reset, resume and driver load, i.e. to call
i915_gem_init_hw instead of the individual pieces we might need.

commit 7e83ccbecd
md/raid10: Allow skipping recovery when clean arrays are assembled
Causes raid10 to skip a recovery in certain cases where it is safe to
do so. Unfortunately it also causes a reshape to be skipped which is
never safe. The result is that an attempt to reshape a RAID10 will
appear to complete instantly, but no data will have been moves so the
array will now contain garbage.
(If nothing is written, you can recovery by simple performing the
reverse reshape which will also complete instantly).
Bug was introduced in 3.10, so this is suitable for 3.10-stable.

There is a bug in 'check_reshape' for raid5.c To checks
that the new minimum number of devices is large enough (which is
good), but it does so also after the reshape has started (bad).
This is bad because
- the calculation is now wrong as mddev->raid_disks has changed
already, and
- it is pointless because it is now too late to stop.
So only perform that test when reshape has not been committed to.
