[PATCH v1 0/3] Fix bugs for realm guest plus BBML2_NOABORT

Posted by Ryan Roberts 1 week, 4 days ago

Hi All,

This fixes a couple of bugs in the "large block mappings for linear map when we
have BBML2_NOABORT" feature when used in conjunction with a CCA realm guest.
While investigating I found and fixed some more general issues too. See commit
logs for full explanations.

Applies on top of v7.0-rc4.

Thanks,
Ryan
