Date: Fri, 27 Dec 2013 09:25:07 -0800 From: "H.J. Lu" <hjl.tools@...il.com> To: "H. Peter Anvin" <hpa@...or.com>, LKML <linux-kernel@...r.kernel.org> Cc: "H.J. Lu" <hjl.tools@...il.com> Subject: [PATCH 3/8] Use __kernel_ulong_t in uapi struct ipc64_perm X32 IPC system call is the same as x86-64 IPC system call, which uses 64-bit integer for unsigned long in struct ipc64_perm. But x32 long is 32 bit. This patch replaces unsigned long in uapi struct ipc64_perm with __kernel_ulong_t if __BITS_PER_LONG == 64. Signed-off-by: H.J.
