From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Message-ID: <4EE05FC5.9000701@ozlabs.org> Date: Thu, 08 Dec 2011 17:57:09 +1100 From: Matt Evans MIME-Version: 1.0 To: linuxppc-dev@ozlabs.org Subject: [PATCH] PPC: Add __SANE_USERSPACE_TYPES__ to asm/types.h for LL64 Content-Type: text/plain; charset=ISO-8859-1 Cc: Ingo Molnar , Paul Mackerras List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , PPC64 uses long long for u64 in the kernel, but powerpc's asm/types.h prevents 64-bit userland from seeing this definition, instead defaulting to u64 == long in userspace. Some user programs (e.g. kvmtool) may actually want LL64, so this patch adds a check for __SANE_USERSPACE_TYPES__ so that, if defined, int-ll64.h is included instead.
