[PATCH] Fix x86_64/msr.h interface to agree with i386/msr.h 

Ever since we remove msr.c from x86_64 branch and started grabbing it from
i386, msr device (read functionality) has been broken for us.

This is due to the differences between asm-i386/msr.h and asm-x86_64/msr.h interfaces.

Here is a patch to our side to fix this.

Thankfully, as of current (2.6.15-rc1-git6) tree, arch/i386/kernel/msr.c is the only file that uses rdmsr_safe macro.
