Tony Luck 1c4f53ca32 x86/mce: Fix check for processor context when machine check was taken. ...

commit 875e26648c upstream.

Linus pointed out that there was no value is checking whether m->ip
was zero - because zero is a legimate value.  If we have a reliable
(or faked in the VM86 case) "m->cs" we can use it to tell whether we
were in user mode or kernelwhen the machine check hit.
