Subject: [PATCH 05/30] x32: Create posix_types_x32.h
Date: Sun, 19 Feb 2012 16:07:43 -0800 [thread overview]
Message-ID: <1329696488-16970-6-git-send-email-hpa@zytor.com> (raw)
In-Reply-To: <1329696488-16970-1-git-send-email-hpa@zytor.com>
From: "H. Peter Anvin" <hpa@zytor.com>
This is the same as the 64-bit posix_types.h, except that
__kernel_[u]long_t is defined to be [unsigned] long long and therefore
64 bits.
Signed-off-by: H. Peter Anvin <hpa@zytor.com>
