Subject: [PATCH] arch: unicore32: kernel: ksyms: remove 'bswapsi2' and 'muldi3' to avoid compiling failure
Date: Wed, 21 May 2014 09:37:08 +0800 [thread overview]
Message-ID: <537C0344.5010509@gmail.com> (raw)
After check the code, 'bswapsi2' and 'muldi3' are useless for
unicore32, so can remove them to avoid compiling failure.
The related error (with allmodconfig under unicore32):
LD init/built-in.o
arch/unicore32/kernel/built-in.o:(___ksymtab+__muldi3+0x0): undefined reference to `__muldi3'
arch/unicore32/kernel/built-in.o:(___ksymtab+__bswapsi2+0x0): undefined reference to `__bswapsi2'
