    Subject[ 022/108] alpha: fix fpu.h usage in userspace
    Date
    From: Greg KH <gregkh@linuxfoundation.org>

    3.5-stable review patch. If anyone has any objections, please let me know.

    ------------------

    From: Mike Frysinger <vapier@gentoo.org>

    commit 0be421862b857e61964435ffcaa7499cf77a5e5a upstream.

    After commit ec2212088c42 ("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
