The sort_entry->cmp() will be called for eventy sample data to find a
matching entry. When it has 'srcline' sort key, that means it needs to
call addr2line or libbfd everytime.
This is not optimal because many samples will have same address and it
just can call addr2line once. So postpone the actual srcline check to
the sort_entry->collpase() and compare addresses in ->cmp().
Also it needs to add ->init() callback to make sure it has srcline info.
If a sample has a unique data, chances are the entry can be sorted out
by other (previous) keys and callbacks in sort_srcline never called.

The -Y/--type-filter option is to filter the result for specific lock
types only. It can accept comma-separated values. Note that it would
accept type names like one in the output. spinlock, mutex, rwsem:R and
so on.
For RW-variant lock types, it converts the name to the both variants.
In other words, "rwsem" is same as "rwsem:R,rwsem:W". Also note that
"mutex" has two different encoding - one for sleeping wait, another for
optimistic spinning. Add "mutex-spin" entry for the lock_type_table so
that we can add it for "mutex" under the table.

To pick the changes in:
86bdf3ebcf ("KVM: Support dirty ring in conjunction with bitmap")
That just rebuilds perf, as these patches don't add any new KVM ioctl to
be harvested for the the 'perf trace' ioctl syscall argument
beautifiers.
This is also by now used by tools/testing/selftests/kvm/, a simple test
build didn't succeed, but for another reason:
lib/kvm_util.c: In function ‘vm_enable_dirty_ring’:
lib/kvm_util.c:125:30: error: ‘KVM_CAP_DIRTY_LOG_RING_ACQ_REL’ undeclared (first use in this function); did you mean ‘KVM_CAP_DIRTY_LOG_RING’?
125 | if (vm_check_cap(vm, KVM_CAP_DIRTY_LOG_RING_ACQ_REL))

I'll send a separate patch for that.

"This contains a number of crasher fixes that were not ready for the

The race windows were found by inspection and the clean-ups appear
sensible and pass regression testing, so we include them here in the
hope that they address the problem. However we remain vigilant because
we don't have 100% certainty yet that the problem is fully addressed.

Pull MSI fixes from Marc Zyngier:
"Thomas tasked me with sending out a few urgent fixes after the giant
MSI rework that landed in 6.2, as both s390 and powerpc ended-up
suffering from it (they do not use the full core code infrastructure,
leading to these previously undetected issues):
- Return MSI_XA_DOMAIN_SIZE as the maximum MSI index when the
architecture does not make use of irq domains instead of returning
0, which is pretty limiting.
- Check for the presence of an irq domain when validating the MSI
iterator, as s390/powerpc won't have one.
- Fix powerpc's MSI backends which fail to clear the descriptor's IRQ
field on teardown, leading to a splat and leaked descriptors"
