Cover letter [PATCH 0/4] x86 smpboot: optimize cpu_up() a bit more...
This set of patches optimizes cpu_up() speed.
Patch 3/4 depends on init_udelay, which was recently added to smpboot.
(and yes, it should havde been in Usec all along --
it seems we somehow checked-in part of an old version of that patch)
cheers,
