Subject: [PATCH 29/29] Tweak i386 arch dependent files to work with PTI
Date: Sat, 13 Jan 2007 13:48:14 +1100 [thread overview]
Message-ID: <20070113024814.29682.37247.sendpatchset@weill.orchestra.cse.unsw.EDU.AU> (raw)
In-Reply-To: <20070113024540.29682.27024.sendpatchset@weill.orchestra.cse.unsw.EDU.AU>
PATCH 29 i386
* Defines default page table config option: PT_DEFAULT in Kconfig.debug
to appear in kernel hacking.
* Adjusts arch dependent files referring to the pgd in the mm_struct
to do it via the new generic page table type (no pgd in mm_struct anymore).
