Some comments on the i386 implementation of smp_lock.h/locks.S
which recently appeared in the kernel:

I agree with most of your commentary. And I bet some of the
improvements will show up. The best test is lmbench's lat_syscall on
an SMP system to see what lock_kernel()'s true overhead really is.

I'll try to merge your stuff in for 2.1.26 if Alan doesn't get to it
first ;-)
