Subject: [PATCH 0/4] x86 smpboot: optimize cpu_up() a bit more...
Date: Sun, 16 Aug 2015 11:45:44 -0400 [thread overview]
Message-ID: <1439739948-21028-1-git-send-email-lenb@kernel.org> (raw)
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,
-Len
