Subject: [PATCH 06/13] [POWERPC] Use lowmem_end_addr to limit lmb allocations on ppc32
Date: Tue, 15 Apr 2008 14:52:24 -0500 [thread overview]
Message-ID: <1208289151-2925-7-git-send-email-galak@kernel.crashing.org> (raw)
In-Reply-To: <1208289151-2925-6-git-send-email-galak@kernel.crashing.org>
Now that we have a proper variable that is the address of the top
of low memory we can use it to limit the lmb allocations.
