MIPS: boot: Fix unaligned access with CONFIG_MIPS_RAW_APPENDED_DTB
commit 4d4f9c1a upstream. The compressed payload is not necesarily 4-byte aligned, at least when compiling with Clang. In that case, the 4-byte value appended to the compressed payload that corresponds to the uncompressed kernel image size must be read using get_unaligned_le32(). This fixes Clang-built kernels not booting on MIPS (tested on a Ingenic JZ4770 board). Fixes: b8f54f2c ("MIPS: ZBOOT: copy appended dtb to the end of the kernel") Cc: <stable@vger.kernel.org> # v4.7 Signed-off-by:Paul Cercueil <paul@crapouillou.net> Reviewed-by:
