Subject: [PATCH 4.4 187/188] mips: disable branch profiling in boot/decompress.o
Date: Mon, 19 Jul 2021 16:52:51 +0200 [thread overview]
Message-ID: <20210719144942.609613328@linuxfoundation.org> (raw)
In-Reply-To: <20210719144913.076563739@linuxfoundation.org>
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")
