From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yinghai Lu Subject: [PATCH 27/50] memblock: Make memblock_alloc_try_nid() fallback to MEMBLOCK_ALLOC_ANYWHERE Date: Tue, 13 Jul 2010 00:10:21 -0700 Message-ID: <1279005044-24777-28-git-send-email-yinghai@kernel.org> References: <1279005044-24777-1-git-send-email-yinghai@kernel.org> Return-path: In-Reply-To: <1279005044-24777-1-git-send-email-yinghai@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: Ingo Molnar , Thomas Gleixner , "H. Peter Anvin" , Andrew Morton , David Miller Cc: Linus Torvalds , Johannes Weiner , linux-kernel@vger.kernel.org, linux-arch@vger.kernel.org, Benjamin Herrenschmidt List-Id: linux-arch.vger.kernel.org From: Benjamin Herrenschmidt 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.
