In linux kernel since version 5.1 (release Date: 2019-05-05)
E0PD (part of the ARMv8.5 extensions) allows us to ensure
that EL0 accesses made via TTBR1 always fault in constant time,
providing similar benefits to KASLR as those provided by KPTI, but
with lower overhead and without disrupting legitimate access to
kernel memory such as SPE.
This option enables E0PD for TTBR1 where available.
