Pull KVM fixes from Paolo Bonzini:
"(Relatively) a lot of reverts, mostly.
Bugs have trickled in for a new feature in 4.2 (MTRR support in
guests) so I'm reverting it all; let's not make this -rc period busier
for KVM than it's been so far. This covers the four reverts from me.
The fifth patch is being reverted because Radim found a bug in the
implementation of stable scheduler clock, *but* also managed to
implement the feature entirely without hypervisor support. So instead
of fixing the hypervisor side we can remove it completely; 4.4 will
get the new implementation"

The cpu feature flags are not ever going to change, so warning
everytime can cause a lot of kernel log spam
(in our case more than 10GB/hour).
The warning seems to only occur when nested virtualization is
enabled, so it's probably triggered by a KVM bug. This is a
sensible and safe change anyway, and the KVM bug fix might not
be suitable for stable releases anyway.

This reverts commit 3c2e7f7de3240216042b61073803b61b9b3cfb22.
Initializing the mapping from MTRR to PAT values was reported to
fail nondeterministically, and it also caused extremely slow boot
(due to caching getting disabled---bug 103321) with assigned devices.

As reported by Dmitry Vyukov, we really shouldn't do ipc_addid() before
having initialized the IPC object state. Yes, we initialize the IPC
object in a locked state, but with all the lockless RCU lookup work,
that IPC object lock no longer means that the state cannot be seen.
We already did this for the IPC semaphore code (see commit e8577d1f0329:
"ipc/sem.c: fully initialize sem_array before making it visible") but we
clearly forgot about msg and shm.

While the lockdep splat is a false positive, becuase path_openat holds i_mutex
of the parent directory and ubifs_init_security() tries to acquire i_mutex
of a new inode, it reveals that taking i_mutex in ubifs_init_security() is
in vain because it is only being called in the inode allocation path
and therefore nobody else can see the inode yet.

Shifting pvclock_vcpu_time_info.system_time on write to KVM system time
MSR is a change of ABI. Probably only 2.6.16 based SLES 10 breaks due
to its custom enhancements to kvmclock, but KVM never declared the MSR
only for one-shot initialization. (Doc says that only one write is
needed.)

Currently poweroff/halt results in a reboot on the Raspberry Pi.
The firmware uses the RSTS register to know which partiton to
boot from. The partiton value is spread into bits
0, 2, 4, 6, 8, 10. Partiton 63 is a special partition used by
the firmware to indicate halt.
The firmware made this change in 19 Aug 2013 and was matched
by the downstream commit:

MAARs should be initialised on each CPU (or rather, core) in the system
in order to achieve consistent behaviour & performance. Previously they
have only been initialised on the boot CPU which leads to performance
problems if tasks are later scheduled on a secondary CPU, particularly
if those tasks make use of unaligned vector accesses where some CPUs
don't handle any cases in hardware for non-speculative memory regions.
Fix this by recording the MAAR configuration from the boot CPU and
applying it to secondary CPUs as part of their bringup.

maar_init was previously only compiled when CONFIG_NEED_MULTIPLE_NODES
was not set, which has been fine since it is only called from the
standard implementation of mem_init which has the same condition. In
preparation for calling it from the SMP startup code on secondary CPUs,
move maar_init outside of the #ifndef such that it is always compiled.

gic_handle_shared_int reads the GIC interrupt pending & mask registers
directly into a bitmap, which is defined as an array of unsigned longs.
The GIC pending registers may be 32 bits wide if the CM is older than
CM3, regardless of the bit width of the CPU, but for MIPS64 kernels
the unsigned longs in the bitmap will be 64 bits wide. In this case we
need to perform 2 x 32 bit reads per 64 bit unsigned long in order to
avoid missing interrupts.

Make use of the mips_cm_vp_id function to convert from Linux CPU numbers
to the VP IDs used by hardware, which are not identical in all systems.
Without doing so we map interrupts to incorrect VP(E)s.

The VP ID of a given CPU may not match up with the CPU number used by
Linux. For example, if the width of the VP part of the VP ID is wider
than log2(number of VPs per core) and the system has multiple cores then
this will be the case. Alternatively, if a pre-r6 system implements the
MT ASE with multiple VPEs per core and Linux is built without support
for the MT ASE then the numbers won't match up either. Provide a
function to convert from CPU number to VP ID.

Fixes for omaps for v4.3-rc cycle:
- Two more patches to fix most of the MMC regressions with the
PBIAS regulator changes. At least two MMC driver related issues
still seems to remain for omap3 legacy booting and omap4 duovero.
Note that the dts changes depend on a recent regulator fix, and
are based on the regulator commit now in mainline kernel
- Enable autoidle for am43xx clocks to prevent clocks from staying
always on
- Fix i2c5 pinctrl offsets for omap5-uevm
- Enable PCA953X as that's needed for HDMI to work on omap5
- Update phy supplies for beagle x15 beta board
- Use palmas-usb for on beagle x15 to start using the related
driver that recently got merged
