Subject: [PATCH -tip v2 2/3] Add weak save_stack_trace_regs()
Date: Wed, 08 Jun 2011 16:09:27 +0900 [thread overview]
Message-ID: <20110608070927.17777.37895.stgit@fedora15> (raw)
In-Reply-To: <20110608070913.17777.37689.stgit@fedora15>
Add weak symbol of save_stack_trace_regs() as same as
save_stack_trace_tsk() since that is not implemented
except x86 yet.
