| Subject: mips: disable branch profiling in boot/decompress.o |
| |
| From: Randy Dunlap <rdunlap@infradead.org> |
| |
| [ 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") |
