This series implements the handling of a pending imprecise abort left behind by the bootloader/firmware running before Linux in the common ARM startup code.
It turns pending imprecise aborts that may signal during the first unmasking of such aborts on the boot CPU into a non-faulting event and warns the user that the firmware of the machine might be buggy. Handling this in the common code makes sure that we only ignore already pending aborts and not those that may happen later during system boot/usage. It also allows to remove the custom fault handler from the 3 architectures that are known to have bad firmware/bootloaders. The patches changing OMAP, MVEBU and BCM5301X are only build tested as I have no hardware to test on. So I would appreciate a tested-by for those.
