+Subject: [PATCH] perf tools: Fix arm64 build error
+
+I'm seeing the following build error on arm64:
+
+  In file included from util/event.c:3:0:
+  util/event.h:95:17: error: 'PERF_REGS_MAX' undeclared here (not in a function)
+    u64 cache_regs[PERF_REGS_MAX];
+                 ^
+
+This patch adds a PERF_REGS_MAX definition for arm64.
