Message-Id: <1453553326-26445-1-git-send-email-albeu@free.fr> Date: Sat, 23 Jan 2016 13:48:15 +0100 From: Alban Bedel <albeu@...e.fr> To: linux-mips@...ux-mips.org Cc: Ralf Baechle <ralf@...ux-mips.org>, Andrew Bresticker <abrestic@...omium.org>, Alex Smith <alex.smith@...tec.com>, Wu Zhangjin <wuzhangjin@...il.com>, linux-kernel@...r.kernel.org, Alban Bedel <albeu@...e.fr>, stable@...r.kernel.org Subject: [PATCH v2 1/4] MIPS: zboot: Fix the build with XZ compression on older GCC versions Some older GCC version (at least 4.6) emits calls to __bswapsi2() when building the XZ decompressor. The link of the compressed image then fails with the following error: arch/mips/boot/compressed/decompress.o: In function '__fswab32': include/uapi/linux/swab.h:60: undefined reference to '__bswapsi2' Add bswapsi.o to the link to fix the build with these versions.
