[PATCH 1/3] um: Define kernel_fpu_begin_mask()

[Eric Biggers <ebiggers@kernel.org>]

Define a stub for kernel_fpu_begin_mask() on user-mode Linux so that
lib/raid/ can switch from kernel_fpu_begin() to kernel_fpu_begin_mask().

Note: this causes a checkpatch error due to the macro's value not having
outer parentheses, but it's left as-is for consistency with the existing
kernel_fpu_begin() and kernel_fpu_end() definitions right next to it.
