└─>Falkor E1003: Incorrect translation due to ASID change
In linux kernel since version 4.2 (release Date: 2015-08-30)
On Falkor v1, an incorrect ASID may be cached in the TLB when ASID
and BADDR are changed together in TTBRx_EL1. Since we keep the ASID
in TTBR1_EL1, this situation only occurs in the entry trampoline and
then only for entries in the walk cache, since the leaf translation
is unchanged. Work around the erratum by invalidating the walk cache
entries for the trampoline before entering the kernel proper.
