Rodriguez" , lguest@lists.ozlabs.org, david.vrabel@citrix.com, boris.ostrovsky@oracle.com Subject: [Xen-devel] [PATCH v3 09/11] x86/boot: add BIT() to boot/bitops.h X-BeenThere: xen-devel@lists.xen.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Sender: xen-devel-bounces@lists.xen.org Errors-To: xen-devel-bounces@lists.xen.org X-Virus-Scanned: ClamAV using ClamSMTP 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.
