+Subject: loongarch: Use ASM_REACHABLE
+
+From: Peter Zijlstra <peterz@infradead.org>
+
+commit 624bde3465f660e54a7cd4c1efc3e536349fead5 upstream.
+
+annotate_reachable() is unreliable since the compiler is free to place
+random code inbetween two consecutive asm() statements.
+
+This removes the last and only annotate_reachable() user.
