From 74768ed833344bb0f82b97cee46320a3d7f09ecd Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 12 Aug 2008 15:08:39 -0700 Subject: [PATCH] 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.
