Add unwind info for sigreturn entry points.

This allows access to the globally shared FIXMAP mapping for ptrace
and frieds, so that debuggers can sanely trace through the vsyscall
sequence.

Schedule work away on an unmap, instead of calling it directly. Should result
in less lost samples, and it fixes a lock ordering problem buffer_sem <-> mmap_sem

Change the lost_mmap_sem stat to lost_no_mm, and account it.

We were doing del_timer_sync() on shutdown, but not ensuring that any queued work
was done as well.

Now we don't do buffer syncs whilst holding current's mmap_sem ever,
we can wait to hold it. Also take task_lock and try to improve the docs a bit.

If there's are multiple tasks sleeping inside the read routine ever, this is necessary.

Clear up the code around  start_sem so it's more obvious, and remove a pointless
down/up pair on buffer_sem (shutdown is already synchronised in sync_stop()).

Consolidate all the arch copies of timer_int.c into one place. Also fixes
a problem with PA-RISC not using instruction_pointer() when it should.

Convention is that error returns are negative.

- Consistent naming (i.e. jhash_xxx)
- Reduces the 2&1 word variants to call jhash_3words()
- Replaces __inline__ with inline.
