H A Dinterrupt.hdiff 3db8aa10de9a478b3086db7894e0266def3d77af Tue Mar 16 05:41:59 CDT 2021 Nicholas Piggin <npiggin@gmail.com> powerpc/64e/interrupt: NMI save irq soft-mask state in C

64e non-maskable interrupts save the state of the irq soft-mask in
asm. This can be done in C in interrupt wrappers as 64s does.

I haven't been able to test this with qemu because it doesn't seem
to cause FSL bookE WDT interrupts.

This makes WatchdogException an NMI interrupt, which affects 32-bit
as well (okay, or create a new handler?)
