Linus,
Please pull the latest core/kprobes git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git core-kprobes-2020-06-01
# HEAD: 66e9b0717102507e64f638790eaece88765cc9e5 kprobes: Prevent probes in .noinstr.text section
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.
Also add a kprobes blacklist for modules.
Signed-off-by: Ingo Molnar <mingo@kernel.org> Thanks,
Ingo
