Subject: [PATCH] Fix broken initialization of conswitchp for ARCH=ppc64
X-Git-Tag: v2.6.16.28-rc1~2806^2~130
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b0faa28493f97b55b36ff5b1a2b8c81bf253a460;p=karo-tx-linux.git

[PATCH] Fix broken initialization of conswitchp for ARCH=ppc64

In the merge tree, commit 0458060c1c59c5378d8fb5daabe18cf4681c35cd
broke boot on some machines because the initialization of conswitchp
was moved to arch/powerpc/kernel/setup_64.c, but a corresponding copy
was not added to arch/ppc64/kernel/setup.c.  This patch fixes it.
