Message-ID: <20120418195544.586415a6@tukaani.org> Date: Wed, 18 Apr 2012 19:55:44 +0300 From: Lasse Collin <lasse.collin@...aani.org> To: Linus Torvalds <torvalds@...ux-foundation.org> Cc: Jan Beulich <JBeulich@...e.com>, linux-kernel@...r.kernel.org Subject: [PATCH] xz: Enable BCJ filters on SPARC and 32-bit x86 From: Lasse Collin <lasse.collin@...aani.org> The BCJ filters were meant to be enabled already on these archs, but the xz_wrap.sh script was buggy. Enabling the filters should give smaller kernel images. xz_wrap.sh will now use $SRCARCH instead of $ARCH to detect the architecture. That way it doesn't need to care about the subarchs (like i386 vs. x86_64) since the BCJ filters don't care either.
