Cover letter [PATCH v4 0/5] Improve watchdog config for arch watchdogs
This is the latest series to make the hardlockup watchdog more easily replaceable by arch code. The last patch provides some justification for why we want to do this (existing sparc watchdog is another that could benefit).
Since last time, we tidied up the Kconfig approach so it was not so jumbled -- Thanks Don and Babu for help and suggestions there.
Since last posting the powerpc patch, I re-added the soft-NMI watchdog, but have it using the emergency stack so we can always avoid the process stacks when perf interrupts are soft-masked.
I'm not sure of the best strategy to merge this. The powerpc watchdog is too much to carry anywhere but powerpc tree now, and watchdog patches seem to go via Andrew...
Thanks,
Nick
