Compiling with GCC 4.8 yields several instances of
crypto/vmac.c: In function ‘vmac_final’:
crypto/vmac.c:616:9: warning: value computed is not used [-Wunused-value]
memset(&mac, 0, sizeof(vmac_t));
^
arch/alpha/include/asm/string.h:31:25: note: in definition of macro ‘memset’
? __builtin_memset((s),0,(n)) \
^
Converting the macro to an inline function eliminates this problem.
However, doing only that causes problems with the GCC 3.x series. The
inline function cannot be named "memset", as otherwise we wind up with
recursion via __builtin_memset. Solve this by adjusting the symbols
such that __memset is the inline, and ___memset is the real function.

alpha: move include/asm-alpha to arch/alpha/include/asm2008-08-15T16:19:40ZLinus Torvaldstorvalds@linux-foundation.org2008-08-15T16:19:40Zurn:sha1:024b246ed24492d6c2ee14c34d742b137fce1b94
Sam Ravnborg did the build-test that the direct header file move works,
I'm just committing it.
This is a pure move:
mkdir arch/alpha/include
git mv include/asm-alpha arch/alpha/include/asm
with no other changes.
