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"
