[ Upstream commit 97e488073cfca0eea84450169ca4cbfcc64e33e3 ]
Use DISABLE_BRANCH_PROFILING for arch/mips/boot/compressed/decompress.o
to prevent linkage errors.
mips64-linux-ld: arch/mips/boot/compressed/decompress.o: in function `LZ4_decompress_fast_extDict':
decompress.c:(.text+0x8c): undefined reference to `ftrace_likely_update'
mips64-linux-ld: decompress.c:(.text+0xf4): undefined reference to `ftrace_likely_update'
mips64-linux-ld: decompress.c:(.text+0x200): undefined reference to `ftrace_likely_update'
mips64-linux-ld: decompress.c:(.text+0x230): undefined reference to `ftrace_likely_update'
mips64-linux-ld: decompress.c:(.text+0x320): undefined reference to `ftrace_likely_update'
mips64-linux-ld: arch/mips/boot/compressed/decompress.o:decompress.c:(.text+0x3f4): more undefined references to `ftrace_likely_update' follow
Fixes: e76e1fdfa8f8 ("lib: add support for LZ4-compressed kernel")
