Merge branch 'core-objtool-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull objtool updates from Ingo Molnar:
"The biggest changes in this cycle were the vmlinux.o optimizations by
Peter Zijlstra, which are preparatory and optimization work to run
objtool against the much richer vmlinux.o object file, to perform
new, whole-program section based logic. That work exposed a handful
of problems with the existing code, which fixes and optimizations are
merged here. The complete 'vmlinux.o and noinstr' work is still work
in progress, targeted for v5.8.

There's also assorted fixes and enhancements from Josh Poimboeuf.

In particular I'd like to draw attention to commit 644592d328370,
which turns fatal objtool errors into failed kernel builds. This
behavior is IMO now justified on multiple grounds (it's easy currently
to not notice an essentially corrupted kernel build), and the commit
has been in -next testing for several weeks, but there could still be
build failures with old or weird toolchains. Should that be widespread
or high profile enough then I'd suggest a quick revert, to not hold up
the merge window"

faster.

This about halves objtool runtime on vmlinux.o, from 34s to 18s.

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"The main changes in this cycle on the kernel side were:

- CPU PMU and uncore driver updates to Intel Snow Ridge, IceLake,
KabyLake, AmberLake and WhiskeyLake CPUs.

- Rework the MSR probing infrastructure to make it more robust, make
it work better on virtualized systems and to better expose it on
sysfs.

- Rework PMU attributes group support based on the feedback from
Greg. The core sysfs patch that adds sysfs_update_groups() was
acked by Greg.

There's a lot of perf tooling changes as well, all around the place:

- vendor updates to Intel, cs-etm (ARM), ARM64, s390,

- various enhancements to Intel PT tooling support:
- Improve CBR (Core to Bus Ratio) packets support.
- Export power and ptwrite events to sqlite and postgresql.
- Add support for decoding PEBS via PT packets.
- Add support for samples to contain IPC ratio, collecting cycles
information from CYC packets, showing the IPC info periodically
- Allow using time ranges

- lots of updates to perf pmu, perf stat, perf trace, eBPF support,
perf record, perf diff, etc. - please see the shortlog and Git log
for details"
