Subject: [PATCH 0/2] Zone boundary alignment fixes, default configuration
Date: Mon, 22 May 2006 10:52:55 +0100 [thread overview]
Message-ID: <exportbomb.1148291574@pinky> (raw)
In-Reply-To: 447173EF.9090000@shadowen.org
I think a concensus is forming that the checks for merging across
zones were removed from the buddy allocator without anyone noticing.
So I propose that the configuration option UNALIGNED_ZONE_BOUNDARIES
default to on, and those architectures which have been auditied
for alignment may turn it off.
Following this email are two patches:
zone-allow-unaligned-zone-boundaries-add-configuration -- adding
the configuration option.
x86-add-zone-alignment-qualifier -- marking x86 as enforcing alignment.
Cheers.
