From: Jan Beulich Date: Tue, 12 Aug 2008 22:08:39 +0000 (-0700) Subject: page allocator: use no-panic variant of alloc_bootmem() in alloc_large_system_hash() X-Git-Tag: v2.6.27-rc3~40 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=74768ed833344bb0f82b97cee46320a3d7f09ecd;p=linux-2.6 page allocator: use no-panic variant of alloc_bootmem() in alloc_large_system_hash() .. since a failed allocation is being (initially) handled gracefully, and panic()-ed upon failure explicitly in the function if retries with smaller sizes failed.
