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.

Merge branch 'dmaengine' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM DMA engine updates from Russell King:
"This looks scary at first glance, but what it is is:
- a rework of the sa11x0 DMA engine driver merged during the previous
cycle, to extract a common set of helper functions for DMA engine
implementations.
- conversion of amba-pl08x.c to use these helper functions.
- addition of OMAP DMA engine driver (using these helper functions),
and conversion of some of the OMAP DMA users to use DMA engine.
Nothing in the helper functions is ARM specific, so I hope that other
implementations can consolidate some of their code by making use of
these helpers.
This has been sitting in linux-next most of the merge cycle, and has
been tested by several OMAP folk. I've tested it on sa11x0 platforms,
and given it my best shot on my broken platforms which have the
amba-pl08x controller.
The last point is the addition to feature-removal-schedule.txt, which
will have a merge conflict. Between myself and TI, we're planning to
remove the old TI DMA implementation next year."

in the following scenario:
vcpu_load
...
vmx_save_host_state
vmx_vcpu_run

interrupt
push ds, es # pushes bad ds, es
schedule
vmx_vcpu_put

pop ds, es # now with rpl=0
iret

resume_userspace
iret # clears ds, es due to mismatched rpl
(instead of resume_userspace, we might return with SYSEXIT and then
take an exception; when the exception IRETs we end up with cleared

Fix by avoiding the optimization on i386 and reloading ds, es on the

KVM: x86: apply kvmclock offset to guest wall clock time
When a guest migrates to a new host, the system time difference from the
previous host is used in the updates to the kvmclock system time visible
to the guest, resulting in a continuation of correct kvmclock based guest
timekeeping.
The wall clock component of the kvmclock provided time is currently not
updated with this same time offset. Since the Linux guest caches the
wall clock based time, this discrepency is not noticed until the guest is
rebooted. After reboot the guest's time calculations are off.
This patch adjusts the wall clock by the kvmclock_offset, resulting in
correct guest time after a reboot.
