Subject: Closing on the CR2 leak bug
Date: Tue, 04 Mar 2014 14:34:00 -0800 [thread overview]
Message-ID: <531654D8.5040409@zytor.com> (raw)
So we need to get something into x86/urgent for the CR2 bug.
It seems like a no-brainer to do the hoisting patch, for which I prefer
the version proposed by Jiri Olsa which reads %cr2 and then passes it to
__do_page_fault() in a GPR:
http://lkml.kernel.org/r/20140228160526.GD1133@krava.brq.redhat.com
As fart as I can tell this should fix Vince's problem as well.
Anyone who objects to this? Otherwise I will put it in tip:x86/urgent
tomorrow.
Do we need any more refinements this late in the -rc cycle?
