Subject: x86: unify current_text_addr
X-Git-Tag: v2.6.25-rc1~1143^2~541
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0ccb8acc51693a2aef0f38024943808046d81251;p=linux-2.6

x86: unify current_text_addr

current_text_addr() has a different implementation in x86_64 and
i386, but it is not fundamentally different. I stick to the i386
implementation, that seem to be a common base, and move it to processor.h
