Subject: [PATCH 0/4] Update CpuDxe MMU Logic to Improve Consistency
Date: Thu, 29 Jun 2023 09:17:54 -0700	[thread overview]
Message-ID: <cover.1687989723.git.t@taylorbeebe.com> (raw)

This patch series:

1. Updates applies uncrustify to noncompliant files
2. Updates GetMemoryRegion() to handle the case where
   BaseAddress is an unmapped page, and update some other
   return values to be more consistent.
3. Adds some branching paths to what were previously only
   ASSERT statements to avoid dereferencing NULL and producing
   non-deterministic behavior when ASSERTs are disabled.
4. Adds function headers to the MMU logic documenting the
   behavior, parameters, and potetial return values.
