Subject: [PATCH 2.6.13] x86_64: Add notify_die() to another spot in do_page_fault()
Date: Thu, 8 Sep 2005 09:38:40 -0700	[thread overview]
Message-ID: <20050908163840.GR3966@smtp.west.cox.net> (raw)

This adds a call to notify_die() in the "no context" portion of
do_page_fault() as someone on the chain might care and want to do a fixup.
