[PATCH] i386: Disallow kprobes on NMI handlers
A kprobe executes IRET early and that could cause NMI recursion and stack
corruption.
Note: This problem was originally spotted by Andi Kleen. This patch
adds fixes not included in his original patch.
[AK: Jan Beulich originally discovered these classes of bugs]
