Catalin Marinas 786889636a arm64: Handle faults caused by inadvertent user access with PAN enabled
When TTBR0_EL1 is set to the reserved page, an erroneous kernel access
to user space would generate a translation fault. This patch adds the
checks for the software-set PSR_PAN_BIT to emulate a permission fault
and report it accordingly.
