[PATCH] Immediate Values - Architecture Independent Code - Fixes following HCH comments

[Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>]

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".
