Peter Anvin" <hpa@...or.com>, x86@...nel.org, Andrew Morton <akpm@...ux-foundation.org> Subject: [PATCH 2/4] Clean up the long arch list for the DEBUG_KMEMLEAK config option This patch introduces HAVE_DEBUG_KMEMLEAK config option and selects it in corresponding architecture Kconfig files. DEBUG_KMEMLEAK now only depends on HAVE_DEBUG_KMEMLEAK.
