task #25552995

commit 4a503217ce37e1f4f3d9b681bbcbbac103776bf1 upstream

Instead disabling interrupts by setting the PSR.I bit, use a priority
higher than the one used for interrupts to mask them via PMR.

When using PMR to disable interrupts, the value of PMR will be used
instead of PSR.[DAIF] for the irqflags.
