Subject: [PATCH v1 0/3] Fix bugs for realm guest plus BBML2_NOABORT
Date: Mon, 23 Mar 2026 13:03:12 +0000	[thread overview]
Message-ID: <20260323130317.1737522-1-ryan.roberts@arm.com> (raw)

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
