Revision d727be7bbf7b68ccc18a3278469325d8f486d75b authored by Atish Patra on 03 April 2020, 01:46:09 UTC, committed by Marc Zyngier on 17 April 2020, 07:59:28 UTC
As per the PLIC specification, maximum priority threshold value is 0x7
not 0xF. Even though it doesn't cause any error in qemu/hifive unleashed,
there may be some implementation which checks the upper bound resulting in
an illegal access.
Fixes: ccbe80bad571 ("irqchip/sifive-plic: Enable/Disable external interrupts upon cpu online/offline")
