Perf PMU drivers using AUX buffers cannot be built as modules unless

The ARM SPE architecture permits an implementation to ignore a sample
if the sample is due to be taken whilst another sample is already being
produced. In this case, it is desirable to report the collision to
userspace, as they may want to lower the sample period.
This patch adds a PERF_AUX_FLAG_C

Any modular driver using cluster-affine PPIs needs to be able to call
irq_get_percpu_devid_partition so that it can enable the IRQ on the
correct subset of CPUs.
This patch exports the symbol so that it can be called from within a

SPE can be used to profile a population of operations in the CPU pipeline

kvm_skip_emulated_instruction() will return 0 if userspace is
single-stepping the guest.
kvm_skip_emulated_instruction() uses return status convention of exit
handler: 0 means "exit to userspace" and 1 means "continue vm entries".
The problem is that nested_vmx_check_vmptr() return status means
so
get_msr() of MSR_EFER is currently always going to succeed, but static
checker doesn't see that far.
Don't complicate stuff and just use 0 for the fallback -- it means that

The hv_pcibus_device structure contains an in-memory hypercall argument
that must not cross a page boundary. Allocate the structure as a page
to ensure that.

Hyper-V vPCI offers different protocol versions. This patch creates the
the infra for negotiating the one to use.

We noticed in testing that affined workloads do not provide consistent
performance under certain circumstances. To isolate the issue, we began
testing with a representative CPU workload. In some cases the CPU workload
results would vary by a large percentage from run to run. We used JTAG and

The group_imbalance path in calculate_imbalance() made sense when it was
added back in 2007 with commit 908a7c1b9b80 ("sched: fix improper load
balance across sched domain") because busiest->load_per_task factored into
the amount of imbalance that was calculated. That is not the case today.

If load_balance() fails to migrate any tasks because all tasks were
affined, load_balance() removes the source cpu from consideration and
attempts to redo and balance among the new subset of cpus.
There is a bug in this code path where the algorithm considers all active
cpus in the system (minus t
This series of patches completely reworks the way inline frames are handled.
Instead of querying for the inline nodes on-demand in the individual tools,
we now create proper callchain nodes for inlined frames. The advantages this
approach brings are numerous:

A follow-up commit will make inline frames first-class citizens
in the callchain, thereby obsoleting all of this special code.

When a callchain entry has no srcline available, we ended up
comparing the instruction pointer. I consider this to be not
too useful. Rather, I think we should group the entries by
function name, which this patch adds. For people who want to
split the data on the IP boundary, using `-g address` is

Instead of showing the (repeated) DSO name of the non-inlined
frame, we now show the "(inlined)" suffix instead.

The original patch that introduced inline frame output in the
various browsers used this suffix already. The new centralized
approach that uses fake symbols for inlined frames was missing
this approach so far.
Instead of changing the symbol name itself, we only print the
suffix where needed. This
The inlined frames use a fake symbol that is tracked in a special
map inside the dso, which is always sorted by name. All other
entries of the symbol beside the function name are unused for
inline frames. The advantage of this approach is that all existing
users of the callchain API can now transpa
Instead of looking up the srcline based on the IP associated with
a given callchain entry, add a new srcline member and use that.
This member is set either based on the IP for non-inlined frames,
or uses the DWARF data for inlined frames.
To ensure we don't duplicate the work for inlined frames, a
