+Subject: [PATCH] Ensure compatibility with ARMv9 by updating .arch directive
+
+The pmem_cvap() function currently uses the '.arch armv8.2-a' directive
+for the 'dc cvap' instruction. This will cause build errors below when
+compiling for ARMv9 systems. Update the '.arch' directive to 'armv9.4-a'
+to ensure compatibility with ARMv9 architectures.
