ARM: cleanup undefined instruction entry code

We don't need to keep reloading the thread into into r10 - we can do
this once and keep the value cached in the register.  Also, schedule
some instructions better so that the pipeline doesn't stall after a
load in the neon code.

ARM: mm: Remove unnecessary CMO in Cortex A15 startup

Cortex-A15 flush L2 cache after reset, there is no need to do this
in software, if L2 is already invalidated in bootloader and
cache is disabled. For secondary startup, there is no reason to
flush L2 as well.

This change assumes the setup code is always entered as the result
of CPU reset.

vfs: Rename end_writeback() to clear_inode()

After we moved inode_sync_wait() from end_writeback() it doesn't make sense
to call the function end_writeback() anymore. Rename it to clear_inode()
which well says what the function really does - set I_CLEAR flag.
