Subject: [PATCH 13/29] Finish abstracting tear down
Date: Sat, 13 Jan 2007 13:46:48 +1100 [thread overview]
Message-ID: <20070113024648.29682.63031.sendpatchset@weill.orchestra.cse.unsw.EDU.AU> (raw)
In-Reply-To: <20070113024540.29682.27024.sendpatchset@weill.orchestra.cse.unsw.EDU.AU>
PATCH 13
* Adjust hugetlb.h to refer to free_pt_range
* Put optimization code in free_pgtables into a macro in
pt_default.h, since it is implementation dependent. Call
free_pt_range from interface in free_pgtables.
