If the events in an evlist's CPU map differ then the entire group is
removed. For example:
```
$ perf stat -e '{imc_free_running/data_read/,imc_free_running/data_write/,cs}' -a sleep 1
WARNING: grouped events cpus do not match, disabling group:
anon group { imc_free_running/data_read/, imc_free_running/data_write/, cs }
```
Change the behavior so that just the events not matching the leader
are removed. So in the example above, just 'cs' will be removed.
Modify the warning so that it is produced once for each group, rather
than once for the entire evlist. Shrink the scope and size of the
warning text buffer.

Setting the leader iterates the list, so rather than use idx (which
may be changed through list reordering) just count the elements and
set afterwards.

Hundreds of "read LOST count failed" error messages may be displayed,
when the below command is launched.
perf record -e '{cpu/mem-loads-aux/,cpu/event=0xcd,umask=0x1/}:S' -a
According to the commit 89e3106fa25fb1b6 ("libperf: Handle read format
in perf_evsel__read()"), the PERF_FORMAT_GROUP is only available for
the leader. However, the record__read_lost_samples() goes through every
entry of an evlist, which includes both leader and member. The member
event errors out and triggers the error message. Since there may be
hundreds of CPUs on a server, the message will be printed hundreds of
times, which is very annoying.
The message itself is correct, but the pr_err is a overkill. Other error
messages in the record__read_lost_samples() are all pr_debug. To make
the output format consistent, change the pr_err("read LOST count
failed\n"); to pr_debug("read LOST count failed\n");.
User can still get the message via -v option.

It expects the values in enum to be a list of names,
now it can also be a dict (YAML object).

I was intending to make all the Netlink Spec code BSD-3-Clause
to ease the adoption but it appears that:
- I fumbled the uAPI and used "GPL WITH uAPI note" there
- it gives people pause as they expect GPL in the kernel
As suggested by Chuck re-license under dual. This gives us benefit
of full BSD freedom while fulfilling the broad "kernel is under GPL"
expectations.

&xdp_buff and &xdp_frame are bound in a way that
xdp_buff->data_hard_start == xdp_frame
It's always the case and e.g. xdp_convert_buff_to_frame() relies on
this.
IOW, the following:
for (u32 i = 0; i < 0xdead; i++) {
xdpf = xdp_convert_buff_to_frame(&xdp);
xdp_convert_frame_to_buff(xdpf, &xdp);
}
shouldn't ever modify @xdpf's contents or the pointer itself.
However, "live packet" code wrongly treats &xdp_frame as part of its
context placed *before* the data_hard_start. With such flow,
data_hard_start is sizeof(*xdpf) off to the right and no longer points
to the XDP frame.
Instead of replacing `sizeof(ctx)` with `offsetof(ctx, xdpf)` in several
places and praying that there are no more miscalcs left somewhere in the
code, unionize ::frm with ::data in a flex array, so that both starts
pointing to the actual data_hard_start and the XDP frame actually starts
being a part of it, i.e. a part of the headroom, not the context.
A nice side effect is that the maximum frame size for this mode gets
increased by 40 bytes, as xdp_buff::frame_sz includes everything from
data_hard_start (-> includes xdpf already) to the end of XDP/skb shared
info.
Also update %MAX_PKT_SIZE accordingly in the selftests code. Leave it
hardcoded for 64 bit && 4k pages, it can be made more flexible later on.
Minor: align `&head->data` with how `head->frm` is assigned for
consistency.
Minor #2: rename 'frm' to 'frame' in &xdp_page_head while at it for
clarity.
(was found while testing XDP traffic generator on ice, which calls
xdp_convert_frame_to_buff() for each XDP frame)

When creating counters with initial delay configured, the enable_on_exec
field is not set. So we need to enable the counters later. The problem
is, when a workload is specified the target__none() is true. So we also
need to check stat_config.initial_delay.
In this change, we add a new field 'initial_delay' for struct target
which could be shared by other subcommands. And define
target__enable_on_exec() which returns whether enable_on_exec should be
set on normal cases.
Before this fix the event is not counted:
$ ./perf stat -e instructions -D 100 sleep 2
Events disabled
Events enabled
Performance counter stats for 'sleep 2':
<not counted> instructions
1.901661124 seconds time elapsed
0.001602000 seconds user
0.000000000 seconds sys
After fix it works:
$ ./perf stat -e instructions -D 100 sleep 2

Performance counter stats for 'sleep 2':
404,214 instructions

Back in 2008 we extended the capability bits from 32 to 64, and we did
it by extending the single 32-bit capability word from one word to an
array of two words. It was then obfuscated by hiding the "2" behind two
macro expansions, with the reasoning being that maybe it gets extended
further some day.
That reasoning may have been valid at the time, but the last thing we
want to do is to extend the capability set any more. And the array of
values not only causes source code oddities (with loops to deal with
it), but also results in worse code generation. It's a lose-lose
situation.
So just change the 'u32[2]' into a 'u64' and be done with it.
We still have to deal with the fact that the user space interface is
designed around an array of these 32-bit values, but that was the case
before too, since the array layouts were different (ie user space
doesn't use an array of 32-bit values for individual capability masks,
but an array of 32-bit slices of multiple masks).
So that marshalling of data is actually simplified too, even if it does
remain somewhat obscure and odd.
This was all triggered by my reaction to the new "cap_isidentical()"
introduced recently. By just using a saner data structure, it went from
unsigned __capi;
CAP_FOR_EACH_U32(__capi) {
if (a.cap[__capi] != b.cap[__capi])
return false;
}
return true;
to just being
return a.val == b.val;
instead. Which is rather more obvious both to humans and to compilers.

The test_local_dnat_portonly() function initiates the client-side as
soon as it sets the listening side to the background. This could lead to
a race condition where the server may not be ready to listen. To ensure
that the server-side is up and running before initiating the
client-side, a delay is introduced to the test_local_dnat_portonly()
function.

- Provide a virtual cache topology to the guest to avoid
inconsistencies with migration on heterogenous systems. Non secure
software has no practical need to traverse the caches by set/way in
the first place.
- Add support for taking stage-2 access faults in parallel. This was an
accidental omission in the original parallel faults implementation,
but should provide a marginal improvement to machines w/o FEAT_HAFDBS
(such as hardware from the fruit company).
- A preamble to adding support for nested virtualization to KVM,
including vEL2 register state, rudimentary nested exception handling
and masking unsupported features for nested guests.
- Fixes to the PSCI relay that avoid an unexpected host SVE trap when
resuming a CPU when running pKVM.
- VGIC maintenance interrupt support for the AIC
- Improvements to the arch timer emulation, primarily aimed at reducing
the trap overhead of running nested.
- Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
interest of CI systems.
- Avoid VM-wide stop-the-world operations when a vCPU accesses its own
redistributor.
- Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions
in the host.
- Aesthetic and comment/kerneldoc fixes
- Drop the vestiges of the old Columbia mailing list and add [Oliver]
as co-maintainer
This also drags in arm64's 'for-next/sme2' branch, because both it and
the PSCI relay changes touch the EL2 initialization code.
RISC-V:
- Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE
- Correctly place the guest in S-mode after redirecting a trap to the guest
- Redirect illegal instruction traps to guest
- SBI PMU support for guest
s390:
- Two patches sorting out confusion between virtual and physical
addresses, which currently are the same on s390.
- A new ioctl that performs cmpxchg on guest memory
- A few fixes
x86:
- Change tdp_mmu to a read-only parameter
- Separate TDP and shadow MMU page fault paths
- Enable Hyper-V invariant TSC control
- Fix a variety of APICv and AVIC bugs, some of them real-world,
some of them affecting architecurally legal but unlikely to
happen in practice
- Mark APIC timer as expired if its in one-shot mode and the count
underflows while the vCPU task was being migrated
- Advertise support for Intel's new fast REP string features
- Fix a double-shootdown issue in the emergency reboot code
- Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give SVM
similar treatment to VMX
- Update Xen's TSC info CPUID sub-leaves as appropriate
- Add support for Hyper-V's extended hypercalls, where "support" at this
point is just forwarding the hypercalls to userspace
- Clean up the kvm->lock vs. kvm->srcu sequences when updating the PMU and
MSR filters
- One-off fixes and cleanups
- Fix and cleanup the range-based TLB flushing code, used when KVM is
running on Hyper-V
- Add support for filtering PMU events using a mask. If userspace
wants to restrict heavily what events the guest can use, it can now
do so without needing an absurd number of filter entries
- Clean up KVM's handling of "PMU MSRs to save", especially when vPMU
support is disabled
- Add PEBS support for Intel Sapphire Rapids
- Fix a mostly benign overflow bug in SEV's send|receive_update_data()
- Move several SVM-specific flags into vcpu_svm
x86 Intel:
- Handle NMI VM-Exits before leaving the noinstr region
- A few trivial cleanups in the VM-Enter flows
- Stop enabling VMFUNC for L1 purely to document that KVM doesn't support
EPTP switching (or any other VM function) for L1
- Fix a crash when using eVMCS's enlighted MSR bitmaps
Generic:
- Clean up the hardware enable and initialization flow, which was
scattered around multiple arch-specific hooks. Instead, just
let the arch code call into generic code. Both x86 and ARM should
benefit from not having to fight common KVM code's notion of how
to do initialization.
- Account allocations in generic kvm_arch_alloc_vm()
- Fix a memory leak if coalesced MMIO unregistration fails
selftests:
- On x86, cache the CPU vendor (AMD vs. Intel) and use the info to emit
the correct hypercall instruction instead of relying on KVM to patch
in VMMCALL
- Use TAP interface for kvm_binary_stats_test and tsc_msrs_test

Pull Compute Express Link (CXL) updates from Dan Williams:
"To date Linux has been dependent on platform-firmware to map CXL RAM
regions and handle events / errors from devices. With this update we
can now parse / update the CXL memory layout, and report events /
errors from devices. This is a precursor for the CXL subsystem to
handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that
for DDR-attached-DRAM is handled by the EDAC driver where it maps
system physical address events to a field-replaceable-unit (FRU /
endpoint device). In general, CXL has the potential to standardize
what has historically been a pile of memory-controller-specific error
handling logic.
Another change of note is the default policy for handling RAM-backed
device-dax instances. Previously the default access mode was "device",
mmap(2) a device special file to access memory. The new default is
"kmem" where the address range is assigned to the core-mm via
add_memory_driver_managed(). This saves typical users from wondering
why their platform memory is not visible via free(1) and stuck behind
a device-file. At the same time it allows expert users to deploy
policy to, for example, get dedicated access to high performance
memory, or hide low performance memory from general purpose kernel
allocations. This affects not only CXL, but also systems with
high-bandwidth-memory that platform-firmware tags with the
EFI_MEMORY_SP (special purpose) designation.
Summary:
- CXL RAM region enumeration: instantiate 'struct cxl_region' objects
for platform firmware created memory regions
- CXL RAM region provisioning: complement the existing PMEM region
creation support with RAM region support
- "Soft Reservation" policy change: Online (memory hot-add)
soft-reserved memory (EFI_MEMORY_SP) by default, but still allow
for setting aside such memory for dedicated access via device-dax.
- CXL Events and Interrupts: Takeover CXL event handling from
platform-firmware (ACPI calls this CXL Memory Error Reporting) and
export CXL Events via Linux Trace Events.
- Convey CXL _OSC results to drivers: Similar to PCI, let the CXL
subsystem interrogate the result of CXL _OSC negotiation.
- Emulate CXL DVSEC Range Registers as "decoders": Allow for
first-generation devices that pre-date the definition of the CXL
HDM Decoder Capability to translate the CXL DVSEC Range Registers
into 'struct cxl_decoder' objects.
- Set timestamp: Per spec, set the device timestamp in case of
hotplug, or if platform-firwmare failed to set it.
- General fixups: linux-next build issues, non-urgent fixes for
pre-production hardware, unit test fixes, spelling and debug
message improvements"

Here is the large set of driver changes for char/misc drivers and other
smaller driver subsystems that flow through this git tree.
Included in here are:
- New IIO drivers and features and improvments in that subsystem
- New hwtracing drivers and additions to that subsystem
- lots of interconnect changes and new drivers as that subsystem seems
under very active development recently. This required also merging
in the icc subsystem changes through this tree.
- FPGA driver updates
- counter subsystem and driver updates
- MHI driver updates
- nvmem driver updates
- documentation updates
- Other smaller driver updates and fixes, full details in the shortlog
All of these have been in linux-next for a while with no reported
problems.

Chuck run into an issue with a single-element attr-set which
only has an attr with value of 0. The search for max attr in
a struct records attrs with value larger than 0 only (max_val
is set to 0 at the start). Adjust the comparison, alternatively
max_val could be init'ed to -1. Somehow picking the last attr
of a value seems like a good idea in general.
