| | | | | | | | | | | | | | | | | | | | | | Commit 6f5317e730505d5cbc851c435a2dfe3d5a21d343 introduced a bug in the handling of userspace object classes that is causing breakage for Xorg when XSELinux is enabled.

| | | | | | | | | | | | | | | | | | | | | | | | MFD changes in 4ec1b54c ('mfd: mfd_cell is now implicitly available to mc13xxx drivers') changed the mc13xxx_platform_data struct layout. At the time all users were changed, but this driver was introduced in another tree at the same time. This updates the mc13xxx_platform_data user, fixing a build error.

The subtle differences are 1) The handler checks for IRQ_DISABLED after the device handler has been called. In case it's set it masks the interrupt. 2) When the handler sees IRQ_DISABLED on entry it masks the interupt in the same way as handle_fastoei_irq, but does not set the IRQ_PENDING flag. 3) Instead of gracefully handling a recursive interrupt it crashes the kernel. #1 is just relevant when a device handler calls disable_irq_nosync() and it does not matter whether we mask the interrupt right away or not. We handle lazy masking for disable_irq anyway, so there is no real reason to have this extra mask in place. #2 will prevent the resend of a pending interrupt, which can result in lost interrupts for edge type interrupts. For level type interrupts the resend is a noop in the generic code. According to the datasheet all interrupts are level type, so marking them as such will result in the exact same behaviour as the private handle_prio_irq implementation. #3 is just stupid. Crashing the kernel instead of handling a problem gracefully is just wrong. With the current semantics- all handlers run with interrupts disabled - this is even more wrong. Rename ack to eoi, remove the unused mask_ack, switch to handle_fasteoi_irq and remove the private function.
