x86: CPA, fix alias checks c_p_a() did not discover all aliases correctly. (such as when called on vmalloc()-ed areas or ioremap()-ed areas) Push the alias checks to the lower, physical level and consistently discover all aliases that might exist: the low direct mappings and the high linear kernel-text mappings (on 64-bit). Thanks to Andi Kleen for pointing out that this was buggy. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
