The series fixes a conflict in memory attributes in some implementations,
such as Neoverse-N3, that causes a data abort in guest EL1 with FSC
0x35 (IMPLEMENTATION DEFINED fault (Unsupported Exclusive or Atomic
access)).
Patch-1 is a cleanup patch that replaces numbers (and comments) to
using proper macros for hardware configuration, such as registers and
page-table entries.
Patch-2 fixes the actual bug and sets the page attrs to Inner-Shareable
by default for the VMs created in the selftests. More details are
presented in the commit text.
