- VFS: converted sb->s_lock to a mutex too. This improves the
create+unlink benchmark on ext3.

- further simplification of __mutex_lock_common(): no more gotos, and
only one atomic_xchg() is done. Code size is now extremely small on
both UP and SMP:

text data bss dec hex filename
398 0 0 398 18e mutex.o.UP

text data bss dec hex filename
463 0 0 463 1cf mutex.o.SMP

- synchro-test updates: max # of threads of 64, fairness stats,
better defaults if =y, cleanups. (David Howells, me)

- FASTCALL -> fastcall in mutex.h (suggested by David Howells)

- documentation updates
