Subject: [PATCH] x86: Make NUMA on 32-bit depend on EXPERIMENTAL again
Date: Wed, 12 Nov 2008 23:26:14 +0100	[thread overview]
Message-ID: <200811122326.16107.rjw@sisk.pl> (raw)
In-Reply-To: <200811122322.36781.rjw@sisk.pl>

From: Rafael J. Wysocki <rjw@sisk.pl>
Subject: x86: Make NUMA on 32-bit depend on EXPERIMENTAL again

My previous patch to make CONFIG_NUMA on x86_32 depend on BROKEN
turned out to be unnecessary, after all, since the source of the
hibernation vs CONFIG_NUMA problem turned out to be the fact that
we didn't take the NUMA KVA remapping into account in the
hibernation code.
