[PATCH] x86: Move swsusp __pa() dependent code to arch portion
o __pa() should be used only on kernel linearly mapped virtual addresses and not on kernel text and data addresses. o Hibernation code needs to determine the physical address associated with kernel symbol to mark a section boundary which contains pages which don't have to be saved and restored during hibernate/resume operation. o Move this piece of code in arch dependent section. So that architectures which don't have kernel text/data mapped into kernel linearly mapped region can come up with their own ways of determining physical addresses associated with a kernel text.
