Subject: [PATCH 0/2] ftrace: fixes for PPC
Date: Sat, 06 Sep 2008 01:06:02 -0400 [thread overview]
Message-ID: <20080906050602.409299112@goodmis.org> (raw)
I spent the day chasing a bug that would hang PPC on boot up when ftrace
is configured in. I found that it was simply a stupid bug I did to
handle the non MCOUNT_RECORD case. Since I was testing only on x86,
and the MCOUNT_RECORD is automatically set for dynamic ftrace if
it is available, I did not test the case where MCOUNT_RECORD was not
set.
I have not finished porting MCOUNT_RECORD to PPC, but have found
that it has caused some issues for archs that do not support it yet.
This patch series handles these cases.
