Merge tag 'core-kprobes-2020-06-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull kprobes updates from Ingo Molnar: "Various kprobes updates, mostly centered around cleaning up the no-instrumentation logic. Instead of the current per debug facility blacklist, use the more generic .noinstr.text approach, combined with a 'noinstr' marker for functions. Also add instrumentation_begin()/end() to better manage the exact place in entry code where instrumentation may be used. And add a kprobes blacklist for modules" * tag 'core-kprobes-2020-06-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: kprobes: Prevent probes in .noinstr.text section vmlinux.lds.h: Create section for protection against instrumentation samples/kprobes: Add __kprobes and NOKPROBE_SYMBOL() for handlers. kprobes: Support NOKPROBE_SYMBOL() in modules kprobes: Support __kprobes blacklist in modules kprobes: Lock kprobe_mutex while showing kprobe_blacklist
