Subject: [PATCH 01/20] xen/const: Introduce _BITUL and _BITULL
Date: Mon, 22 Apr 2019 17:49:18 +0100	[thread overview]
Message-ID: <20190422164937.21350-2-julien.grall@arm.com> (raw)
In-Reply-To: <20190422164937.21350-1-julien.grall@arm.com>

The pattern _AC(1, UL{,L}) << X is commonly used in the headers to make
define usuable in both assembly and C.

So introduce _BITUL and _BITULL to make the code slightly more readable.

The idea has been taken from Linux (see include/uapi/linux.h).
