+Subject: [PATCH] PR32930 backends/: guard asm/perf_regs.h include
+
+asm/perf_regs.h is an arch-specific linux include, not present on
+architectures like hppa and m68k that lack perf_events support.
+
+Only one place we need to fix; others already guard the include by
+architecture, or use architecture-independent headers (e.g.
+linux/perf_events.h).
+
+* backends/libebl_PERF_FLAGS.h: Only include asm/perf_regs.h on
+  architectures where we use it.
