H A Dthread_a64.S2dac4a2df8f65b7e95a1c0f4ca98c6da6b93dde9 Wed May 18 13:09:00 UTC 2016 Jens Wiklander <jens.wiklander@linaro.org> core: fix fiq delivery in Aarch64

Prior to this patch reception of a FIQ while in secure user mode (secure
EL0) would be treated as if an IRQ was received instead. This resulted
in an exit to normal world and when FIQ was unmasked it would be
re-triggered but this time received as an FIQ received while in normal
world.

This patch fixes this and handles FIQ directly when received while in
secure user mode.
