misc/pvpanic: split-up generic and platform dependent code Split-up generic and platform dependent code in order to be able to re-use generic event handling code in pvpanic PCI device driver in the next patches. The code from pvpanic.c was split in two new files: - pvpanic.c: generic code that handles pvpanic events - pvpanic-mmio.c: platform/bus dependent code Signed-off-by: Mihai Carabas <mihai.carabas@oracle.com> Link: https://lore.kernel.org/r/1616597356-20696-2-git-send-email-mihai.carabas@oracle.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

misc/pvpanic: probe multiple instances Create the mecahism that allows multiple pvpanic instances to call pvpanic_probe and receive panic events. A global list will retain all the mapped addresses where to write panic events.

misc/pvpanic: Make 'pvpanic_probe()' resource managed Simplify code and turn 'pvpanic_probe()' into a managed resource version. This simplify callers that don't need to do some clean-up on error in the probe and on remove. Update pvpanic-mmio.c and pvpanic-pci.c accordingly. 'pvpanic_remove()' don't need to be exported anymore.
