Immediate Values - Architecture Independent Code - Fixes following HCH comments
Various coding style fixes following Christoph's comments
Put asm-generic/immediate.h content into linux/immediate.h.
Remove ifdef __KERNEL__ in .h never exported to user space.
Make immediate_mutex static.
It applies after "Immediate Values - Architecture Independent Code".
