From ed26dbe5ae045e5bf95c6dc27497397a3fde52e1 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Wed, 4 Mar 2009 16:16:51 -0800 Subject: x86: pre-initialize boot_cpu_data.x86_phys_bits to avoid system_state tests Impact: cleanup, micro-optimization Pre-initialize boot_cpu_data.x86_phys_bits to a reasonable default to remove the use of system_state tests in __virt_addr_valid() and __phys_addr().
