Hi Everybody,

Today I was trying to build 3.15.2 on AMD64 from kernel 3.14.8 and get this:

CC fs/mbcache.o
fs/mbcache.c: In function ‘__spin_lock_mb_cache_entry’:
fs/mbcache.c:134: error: SSE register return with SSE disabled
make[1]: *** [fs/mbcache.o] Error 1

google doesn't reveal much except that floating point shouldn't be used
in the kernel, but I am not experienced enough to see how or what is
going on here.

Any help appreciated.

Please cc me.
