[PATCH] x86, paravirt: BUG_ON on {rd,wr}msr exceptions
When CONFIG_PARAVIRT is enabled, the kernel is ignoring exceptions on the {rd,wr}msr instructions. This makes serious issues (either on the guest kernel, or on the host) be silently ignored, and is different from the native MSR code (which does not ignore the exceptions). As paravirt.h already includes linux/bug.h, I don't see what was the original issue preventing BUG_ON from being used.
