ARM: EXYNOS: add a register base address variable in mct controller driver

All the MCT register read/writes use a fixed remapped address
S5P_VA_SYSTIMER.  With device tree support for MCT controller,
it is possible to remove the static remap of the MCT controller
address space and do the remap during the initialization of the
MCT controller with the physical address obtained from the device

So in preparation of adding device tree support for MCT controller,
add a new register base address variable that will hold the remapped
MCT controller base address and convert all MCT register read/writes
to use this new variable as the base address instead of the fixed
S5P_VA_SYSTIMER.

While at it, the MCT register offset and bit mask definitions are
moved into the MCT controller driver file since there are no other

fix compat_sys_rt_sigprocmask()

Converting bitmask to 32bit granularity is fine, but we'd better
_do_ something with the result.  Such as "copy it to userland"...

 "The biggest feature in the pull is the new (and still experimental)
  raid56 code that David Woodhouse started long ago.  I'm still working
  on the parity logging setup that will avoid inconsistent parity after
  a crash, so this is only for testing right now.  But, I'd really like
  to get it out to a broader audience to hammer out any performance
  issues or other problems.

  scrub does not yet correct errors on raid5/6 either.

  Josef has another pass at fsync performance.  The big change here is
  to combine waiting for metadata with waiting for data, which is a big
  latency win.  It is also step one toward using atomics from the
  hardware during a commit.

  Mark Fasheh has a new way to use btrfs send/receive to send only the
  metadata changes.  SUSE is using this to make snapper more efficient
  at finding changes between snapshosts.

  Snapshot-aware defrag is also included.

  Otherwise we have a large number of fixes and cleanups.  Eric Sandeen
  wins the award for removing the most lines, and I'm hoping we steal
  this idea from XFS over and over again."

ext4: don't allow quota mount options when quota feature enabled

So far we silently ignored when quota mount options were set while quota
feature was enabled.  But this can create confusion in userspace when
mount options are set but silently ignored and also creates opportunities
for bugs when we don't properly test all quota types.  Actually
ext4_mark_dquot_dirty() forgets to test for quota feature so it was
dependent on journaled quota options being set.  OTOH ext4_orphan_cleanup()
tries to enable journaled quota when quota options are specified which is
wrong when quota feature is enabled.
