Rodriguez" List-Id: xen-devel@lists.xenproject.org The boot/bitops.h has guards against including the regular bitops (include/asm-generic/bitops.h), it only implements what we need at early boot. We'll be making use of BIT() later so add it. Users of boot/boot.h must include it prior to asm/setup.h otherwise the guard protection devised against the regular linux/bitops.h will not take effect. v2: spelling fixes, and language descriptipon enhancements by Konrad. v3: Parenthesize (x), just match what is in include/linux/bitmap.h Reviewed-by: Konrad Rzeszutek Wilk Signed-off-by: Luis R.
