Hi Naman, Saurabh,
So awesome to see the ARM64 support for the VSM being upstreamed!!
Few of the patches carry my old Microsoft "Signed-off-by" tag,
and I really appreciate you folks very much kindly adding it
although the code appears to be a far more evolved and crisper
version of what it was back then!
Do feel free to drop my SOB from these few patches so the below SRB
doesn't look weird or as a conflict of interest - that is if you see
adding my below SRB to these few patches as a good option. It's been
2 years, and after 2 years who can really remember their code :D
For the series,
