Steven Rostedt c0525a6972 x86: Reset the debug_stack update counter ... When an NMI goes off and it sees that it preempted the debug stack, to keep the debug stack safe, it changes the IDT to point to one that does not modify the stack on breakpoint (to allow breakpoints in NMIs). But the variable that gets set to know to undo it on exit never gets cleared on exit. Thus every NMI will reset it on exit the first time it is done even if it does not need to be reset. [ Added H. Peter Anvin's suggestion to use this_cpu_read/write ] Cc: <stable@vger.kernel.org> # v3.3 Signed-off-by: Steven Rostedt <rostedt@goodmis.org>		2012-05-31 23:12:20 -04:00
