Xiao Guangrong 16b854c889 KVM: iommu: fix releasing unmapped page
There are two bugs:
- the 'error page' is forgot to be released
  [ it is unneeded after commit a2766325cf, for backport, we
    still do kvm_release_pfn_clean for the error pfn ]

- guest pages are always released regardless of the unmapped page
  (e,g, caused by hwpoison)

Takuya Yoshikawa d89cc617b9 KVM: Push rmap into kvm_arch_memory_slot
Two reasons:
 - x86 can integrate rmap and rmap_pde and remove heuristics in
   __gfn_to_rmap().
 - Some architectures do not need rmap.

Since rmap is one of the most memory consuming stuff in KVM, ppc'd
better restrict the allocation to Book3S HV.

Linus Torvalds e7882d6c40 Merge branch 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull VFS fixes and cleanups from Al Viro.

Most of this is the series to remove sync_supers() and the
->write_supers VFS callback from Artem Bityutskiy.  One commit to do the
actual removal work, a whole series of commits to fix up stale comments
etc all over the tree.

There's also a regression fix for an incorrect use of mnt_drop_write()
in do_dentry_open().

Artem Bityutskiy f0cd2dbb6c vfs: kill write_super and sync_supers
Finally we can kill the 'sync_supers' kernel thread along with the
'->write_super()' superblock operation because all the users are gone.
Now every file-system is supposed to self-manage own superblock and
its dirty state.

The nice thing about killing this thread is that it improves power management.
Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up
every 5 seconds no matter what - even if there were no dirty superblocks and
even if there were no file-systems using this service (e.g., btrfs and
journalled ext4 do not need it). So it was wasting power most of the time. And
because the thread was in the core of the kernel, all systems had to have it.
So I am quite happy to make it go away.

Interestingly, this thread is a left-over from the pdflush kernel thread which
was a self-forking kernel thread responsible for all the write-back in old
Linux kernels. It was turned into per-block device BDI threads, and
'sync_supers' was a left-over. Thus, R.I.P, pdflush as well.

by acpi_processor_cst_has_changed() inside the acpi_cpu_soft_notify(). This

  arch/x86/platform and into drivers/platform/olpc.

  OLPC machines are now ARM-based (which means lots of x86 and ARM

  sense to go through a separate OLPC tree after getting the appropriate
  review/ACKs."

Linus Torvalds 44d82e2963 ARM: arm-soc Marvell Orion device-tree updates
This branch contains a set of device-tree conversions for Marvell Orion
 platforms that were staged early but took a few tries to get the branch
 into a format where it was suitable for us to pick up.
 
 Given that most people working on these platforms are hobbyists with
 limited time, we were a bit more flexible with merging it even though
 it came in late.

Linus Torvalds bfdf85dfce ARM: arm-soc: cpuidle enablement for OMAP
Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree, but
 didn't go in because the pull request ended up rejected. So it just got
 merged, and we got this staged branch that enables the coupled cpuidle
 code on OMAP.
 
 With a stable git workflow from the other maintainer we could have staged
 this earlier, but that wasn't the case so we have had to merge it late.
 
 The alternative is to hold it off until 3.7 but given that the code is
 well-isolated to OMAP and they are eager to see it go in, I didn't push
 back hard in that direction.
