From 744525092727827a9cf0044074db3e22dcf354fd Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Wed, 11 Feb 2009 16:31:40 -0800 Subject: [PATCH] x86: merge sys_rt_sigreturn between 32 and 64 bits Impact: cleanup With the recent changes in the 32-bit code to make system calls which use struct pt_regs take a pointer, sys_rt_sigreturn() have become identical between 32 and 64 bits, and both are empty wrappers around do_rt_sigreturn(). Remove both wrappers and rename both to sys_rt_sigreturn(). Cc: Brian Gerst Cc: Tejun Heo Signed-off-by: H.
