2021-05-27misc/pvpanic: Make 'pvpanic_probe()' resource managedChristophe JAILLET
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.

2021-05-27misc/pvpanic-mmio: Use GFP_KERNEL instead of GFP_ATOMICChristophe JAILLET
There is no need to use GFP_ATOMIC in a probe function. Use GFP_KERNEL instead.

2021-05-27misc/pvpanic-mmio: Fix error handling in 'pvpanic_mmio_probe()'Christophe JAILLET
There is no error handling path in the probe function. Switch to managed resource so that errors in the probe are handled easily and simplify the remove function accordingly.

2021-03-28misc/pvpanic: probe multiple instancesMihai Carabas
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.

2021-03-28misc/pvpanic: split-up generic and platform dependent codeMihai Carabas
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>
