From 44eeab67416711db9b84610ef18c99a60415dff8 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Fri, 19 Jun 2009 15:01:44 +0100 Subject: MIPS: Hibernation: Remove SMP TLB and cacheflushing code. We can't perform any flushes on SMP from swsusp_arch_resume because interrupts are disabled. A cross-CPU flush is unnecessary anyway because all but the local CPU have already been disabled. A local flush is not needed either because we didn't change any mappings. So just delete the code.
