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. v1: https://lore.kernel.org/all/20250404220659.1312465-1-rananta@xxxxxxxxxx/ v1 -> v2: Addressed Oliver's comments (thank you) - Moved the TCR_* macros from tools' sysreg.h to selftests' local processor.h in patch-1. - Adjsted the citations to describe the issue more appropriately in patch-2.
