From 3b99a3ef55b292180473a221f3d6bc24455f0632 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Fri, 1 Jul 2011 02:25:17 +0200 Subject: x86,64: Separate arg1 from rbp handling in SAVE_REGS_IRQ Just for clarity in the code. Have a first block that handles the frame pointer and a separate one that handles pt_regs pointer and its use. Signed-off-by: Frederic Weisbecker Cc: Ingo Molnar Cc: Thomas Gleixner Cc: H.
