+         On Falkor v1, an incorrect ASID may be cached in the TLB when ASID
+         and BADDR are changed together in TTBRx_EL1. The workaround for this
+         issue is to use a reserved ASID in cpu_do_switch_mm() before
+         switching to the new ASID. Saying Y here selects ARM64_PAN if
+         ARM64_SW_TTBR0_PAN is selected. This is done because implementing and
+         maintaining the E1003 workaround in the software PAN emulation code
+         would be an unnecessary complication. The affected Falkor v1 CPU
+         implements ARMv8.1 hardware PAN support and using hardware PAN
+         support versus software PAN emulation is mutually exclusive at
+         runtime.
