Modified Files: src/sys/arch/amd64/amd64: asan.c spl.S Log Message: Explicitly unpoison the stack when entering a softint. Softints are the only place where we "discard" a part of the stack: we may have left the thread without allowing the asan instrumentation to clear the poison, and in this case, we can get false positives when we hit a poisoned area of the stack while executing another handler within the same softint thread. (I was actually getting a rare false positive in ip6intr.)
