x86, espfix: Fix broken header guard Header guard is #ifndef, not #ifdef... Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com> 2014-05-03 02:33:51 +08:00			`#ifndef _ASM_X86_ESPFIX_H`
x86, espfix: Move espfix definitions into a separate header file Sparse warns that the percpu variables aren't declared before they are defined. Rather than hacking around it, move espfix definitions into a proper header file. Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: H.

x86/espfix: Add 'cpu' parameter to init_espfix_ap() Add a CPU index parameter to init_espfix_ap(), so that the parameter could be propagated to the function for espfix page allocation.
