Subject: sparc64: Add missing notify_cpu_starting() call.
X-Git-Tag: v2.6.28-rc1~606^2~1
X-Git-Url: https://bbs.cooldavid.org/git/?a=commitdiff_plain;h=82960b8543cca5797a5e2841a9c43b8c5c669e65;p=net-next-2.6.git

sparc64: Add missing notify_cpu_starting() call.

Commit e545a6140b698b2494daf0b32107bdcc5e901390 ("kernel/cpu.c: create
a CPU_STARTING cpu_chain notifier") added a notify_cpu_starting()
notifier event, and hit every arch except sparc64.

Fix that missed case.
