Hello,
I will spin the new patches here, in this thread. However I dont know whom to
address this patch - after it is well tested. Maybe I will convert the msr.c
driver for this new calls too.
This patch adds support for _safe (exception handled) variants of rdmsr_on_cpu
and wrmsr_on_cpu. This is needed for the new coretemp driver, which might step
into non-existing MSR (poorly documented).

Alexey, are you the right person to pass this to? LKML maybe?
To correct my statement about the include file:
CHK include/linux/version.h
CHK include/linux/utsrelease.h
CC arch/x86_64/kernel/asm-offsets.s
In file included from include/asm/processor.h:16,
from include/linux/prefetch.h:14,
from include/linux/list.h:8,
from include/linux/module.h:10,
from include/linux/crypto.h:21,
from arch/x86_64/kernel/asm-offsets.c:7:
include/asm/msr.h: In function 'rdmsr_safe_on_cpu':
include/asm/msr.h:179: error: 'EIO' undeclared (first use in this function)
include/asm/msr.h:179: error: (Each undeclared identifier is reported only once
