Subject: [PATCH 25/49] memblock: Make memblock_alloc_try_nid() fallback to MEMBLOCK_ALLOC_ANYWHERE
Date: Tue, 6 Jul 2010 15:39:18 -0700 [thread overview]
Message-ID: <1278455982-24621-26-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1278455982-24621-1-git-send-email-yinghai@kernel.org>
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
memblock_alloc_nid() used to fallback to allocating anywhere by using
memblock_alloc() as a fallback.
However, some of my previous patches limit memblock_alloc() to the region
covered by MEMBLOCK_ALLOC_ACCESSIBLE which is not quite what we want
for memblock_alloc_try_nid().
So we fix it by explicitely using MEMBLOCK_ALLOC_ANYWHERE.
Not that so far only sparc uses memblock_alloc_nid() and it hasn't been updated
to clamp the accessible zone yet. Thus the temporary "breakage" should have
no effect.
