Subject: arm: allow usage of string functions in linux/string.h
In introducing a trivial "strstarts()" function in linux/string.h, we
hit:
arch/arm/boot/compressed/misc.o: In function `strstarts':
misc.c:(.text+0x368): undefined reference to `strlen'
misc.c:(.text+0x378): undefined reference to `strncmp'
This is because of "CFLAGS_misc.o := -Dstatic=" in the Makefile.
"static inline strstarts(...)" becomes non-inline, and refers to the
other string ops.
The simplest workaround is to include asm/string.h. This makes sense
anyway, since lib/string.c won't be linked against this so we can't
use those functions anyway.
Compile tested here.
