Subject[GIT PULL] kprobes updates for v5.8
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
