When the host crashes it would sometimes be nice to have additional
debug data available which could be produced via debug keys, but
halting the server for manual intervention might be impossible due to
the need to reboot/kexec rather sooner than later.
Add support for automatic debug key actions in case of crashes which
can be activated via boot- or runtime-parameter.
Changes in V4:
- addressed comments (now patch 3)
- added patches 1 and 2
Changes in V5:
- better bug frame construction on Arm (patch 1)
- addressed comments
Juergen Gross (3):
xen/arm: add support for run_in_exception_handler()
xen: enable keyhandlers to work without register set specified
xen: add support for automatic debug key actions in case of crash
