Subject: [PATCH] Remove unneeded #defines in head.S
X-Git-Tag: v2.6.14-rc1~1037^2~22
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1d086e6bd605ac44154e019fe96ae3568e8b2ba2;p=linux-2.6

[PATCH] Remove unneeded #defines in head.S

arch/ppc64/kernel/head.S #defines SECONDARY_PROCESSORS then has some
#ifdefs based on it.  Whatever purpose this had is long lost, this
patch removes it.

Likewise, head.S defines H_SET_ASR, which is now defined, along with
other hypervisor call numbers in hvcall.h.  This patch deletes it, as
well, from head.S.
