alpha: fix fpu.h usage in userspace

After commit ec22120 ("Disintegrate asm/system.h for Alpha"), the fpu.h header which we install for userland started depending on special_insns.h which is not installed. However, fpu.h only uses that for __KERNEL__ code, so protect the inclusion the same way to avoid build breakage in glibc: /usr/include/asm/fpu.h:4:31: fatal error: asm/special_insns.h: No such file or directory Cc: [email protected] Reported-by: Matt Turner <[email protected]> Signed-off-by: Mike Frysinger <[email protected]> Signed-off-by: Michael Cree <[email protected]> Acked-by: Matt Turner <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
