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 <brgerst@gmail.com> Cc: Tejun Heo <tj@kernel.org> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
