Cover letter [Xenomai-core] [PATCH 0/3] x86: Fix & update NMI watchdog
This series reanimates the NMI watchdog support for current x86 CPUs. It adds the required bits for Intel Core2 (and probably later) performance counters, fixes an overflow condition for P6 perf-counters, adds x86-64 support, and comes with a more robust NMI reason detection + pass-through for other events. The latter allows to use the NMI watchdog together with KGDB.
As usual, the series /may/ cause build (or even runtime) regressions for untested platforms. These are: kernel 2.4, x86-32. Feedback and/or corrections appreciated!
