Re: [PATCH 7/8] i386: bitops: Kill needless usage of __asm__ __volatile__ II

BTW if you want to optimize inline asm code a bit -- find_first_bit /
find_first_zero_bit / for_each_cpu could really benefit from a optimized version
for cpumask_t sized bitmaps. That would save a lot of cycles in some of the
hotter paths of the kernel like the scheduler.
