The patch titled
Subject: lz4: fix KERNEL_LZ4 support
has been removed from the -mm tree. Its filename was
lib-update-lz4-compressor-module-fix.patch
This patch was dropped because it was folded into lib-update-lz4-compressor-module.patch
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: lz4: fix KERNEL_LZ4 support
The updated lz4 library removed the #ifdef guards around the various
EXPORT_SYMBOL statements in the original kernel lz4 support, which broke
CONFIG_KERNEL_LZ4 on x86:
x86_64-linux-ld: -r and -pie may not be used together
scripts/Makefile.build:308: recipe for target 'arch/x86/boot/compressed/misc.o' failed
This uses a simpler way to do the same thing, by overriding the
EXPORT_SYMBOL macro.
