From 83460ec8dcac14142e7860a01fa59c267ac4657c Mon Sep 17 00:00:00 2001
From: Andi Kleen <ak@linux.intel.com>

Subject: [PATCH] syscalls.h: use gcc alias instead of assembler aliases for
syscalls
Use standard gcc __attribute__((alias(foo))) to define the syscall aliases
instead of custom assembler macros.
This is far cleaner, and also fixes my LTO kernel build.
