These days we can use static_assert() in the logical place rather than
jamming a BUILD_BUG_ON() into the nearest function scope.

While CMN_MAX_DIMENSION was bumped to 12 for CMN-650, that only supports
up to a 10x10 mesh, so bumping dtm_idx to 256 bits at the time worked
out OK in practice. However CMN-700 did finally support up to 144 XPs,
and thus needs a worst-case 288 bits of dtm_idx for an aggregated XP
event on a maxed-out config. Oops.

The scope of the "extra device ports" configuration is not made clear by
the CMN documentation - so far we've assumed it applies globally, based
on the sole example which suggests as much. However it transpires that
this is incorrect, and the format does in fact vary based on each
individual XP's port configuration. As a consequence, we're currenly
liable to decode the port/device indices from a node ID incorrectly,
thus program the wrong event source in the DTM leading to bogus event
counts, and also show device topology on the wrong ports in debugfs.
To put this right, rework node IDs yet again to carry around the
additional data necessary to decode them properly per-XP. At this point
the notion of fully decomposing an ID becomes more impractical than it's
worth, so unabstracting the XY mesh coordinates (where 2/3 users were
just debug anyway) ends up leaving things a bit simpler overall.

Currently users can get the Root Ports supported by the PCIe PMU by
"bus" sysfs attributes which indicates the PCIe bus number where
Root Ports are located. This maybe insufficient since Root Ports
supported by different PCIe PMUs may be located on the same PCIe bus.
So export the BDF range the Root Ports additionally.

We make the initial value of event ctrl register as HISI_PCIE_INIT_SET
and modify according to the user options. This will make TLP headers
bandwidth only counting never take effect since HISI_PCIE_INIT_SET
configures to count the TLP payloads bandwidth. Fix this by making
the initial value of event ctrl register as 0.

Currently we set the period and record it as the initial value of the
counter without checking it's set to the hardware successfully or not.
However the counter maybe unwritable if the target event is unsupported
by the device. In such case we will pass user a wrong count:
[start counts when setting the period]
hwc->prev_count = 0x8000000000000000
device.counter_value = 0 // the counter is not set as the period
[when user reads the counter]
event->count = device.counter_value - hwc->prev_count
= 0x8000000000000000 // wrong. should be 0.
Fix this by record the hardware counter counts correctly when setting
the period.

Use perf_allow_kernel() for 'pa_enable' (physical addresses),
'pct_enable' (physical timestamps) and context IDs. This means that
perf_event_paranoid is now taken into account and LSM hooks can be used,
which is more consistent with other perf_event_open calls. For example
PERF_SAMPLE_PHYS_ADDR uses perf_allow_kernel() rather than just
perfmon_capable().
This also indirectly fixes the following error message which is
misleading because perf_event_paranoid is not taken into account by
perfmon_capable():
$ perf record -e arm_spe/pa_enable/
Error:

Armv9.4/8.9 PMU adds optional support for a fixed instruction counter
similar to the fixed cycle counter. Support for the feature is indicated
in the ID_AA64DFR1_EL1 register PMICNTR field. The counter is not
accessible in AArch32.
Existing userspace using direct counter access won't know how to handle
the fixed instruction counter, so we have to avoid using the counter
when user access is requested.

There are 2 defines for the number of PMU counters:
ARMV8_PMU_MAX_COUNTERS and ARMPMU_MAX_HWEVENTS. Both are the same
currently, but Armv9.4/8.9 increases the number of possible counters
from 32 to 33. With this change, the maximum number of counters will
differ for KVM's PMU emulation which is PMUv3.4. Give KVM PMU emulation
its own define to decouple it from the rest of the kernel's number PMU
counters.
The VHE PMU code needs to match the PMU driver, so switch it to use
ARMPMU_MAX_HWEVENTS instead.

Various PMUv3 registers which are a mask of counters are 64-bit
registers, but the accessor functions take a u32. This has been fine as
the upper 32-bits have been RES0 as there has been a maximum of 32
counters prior to Armv9.4/8.9. With Armv9.4/8.9, a 33rd counter is
added. Update the accessor functions to use a u64 instead.

Xscale and Armv6 PMUs defined the cycle counter at 0 and event counters
starting at 1 and had 1:1 event index to counter numbering. On Armv7 and
later, this changed the cycle counter to 31 and event counters start at
0. The drivers for Armv7 and PMUv3 kept the old event index numbering
and introduced an event index to counter conversion. The conversion uses
masking to convert from event index to a counter number. This operation
relies on having at most 32 counters so that the cycle counter index 0
can be transformed to counter number 31.
Armv9.4 adds support for an additional fixed function counter
(instructions) which increases possible counters to more than 32, and
the conversion won't work anymore as a simple subtract and mask. The
primary reason for the translation (other than history) seems to be to
have a contiguous mask of counters 0-N. Keeping that would result in
more complicated index to counter conversions. Instead, store a mask of
available counters rather than just number of events. That provides more
information in addition to the number of events.
No (intended) functional changes.

Use of_property_present() to test for property presence rather than
of_find_property(). This is part of a larger effort to remove callers
of of_find_property() and similar functions. of_find_property() leaks
the DT struct property and data pointers which is a problem for
dynamically allocated nodes which may be freed.

Pull x86 fixes from Thomas Gleixner:
- Fix 32-bit PTI for real.
pti_clone_entry_text() is called twice, once before initcalls so that
initcalls can use the user-mode helper and then again after text is
set read only. Setting read only on 32-bit might break up the PMD
mapping, which makes the second invocation of pti_clone_entry_text()
find the mappings out of sync and failing.
Allow the second call to split the existing PMDs in the user mapping
and synchronize with the kernel mapping.
- Don't make acpi_mp_wake_mailbox read-only after init as the mail box
must be writable in the case that CPU hotplug operations happen after
boot. Otherwise the attempt to start a CPU crashes with a write to
read only memory.
- Add a missing sanity check in mtrr_save_state() to ensure that the
fixed MTRR MSRs are supported.
Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but
the WARN_ON() can bring systems down when panic on warn is set.

Pull time keeping fixes from Thomas Gleixner:
- Fix a couple of issues in the NTP code where user supplied values are
neither sanity checked nor clamped to the operating range. This
results in integer overflows and eventualy NTP getting out of sync.
According to the history the sanity checks had been removed in favor
of clamping the values, but the clamping never worked correctly under
all circumstances. The NTP people asked to not bring the sanity
checks back as it might break existing applications.
Make the clamping work correctly and add it where it's missing
- If adjtimex() sets the clock it has to trigger the hrtimer subsystem
so it can adjust and if the clock was set into the future expire
timers if needed. The caller should provide a bitmask to tell
hrtimers which clocks have been adjusted.
adjtimex() uses not the proper constant and uses CLOCK_REALTIME
instead, which is 0. So hrtimers adjusts only the clocks, but does
not check for expired timers, which might make them expire really
late. Use the proper bitmask constant instead.

bcachefs_metadata_version_disk_accounting_v2 accidentally included
padding in disk_accounting_key; fortunately, 6.11 isn't out yet so
we can fix this with another version bump"

The section 4.5.2 of the RISC-V AIA specification says that "any write
to a sourcecfg register of an APLIC might (or might not) cause the
corresponding interrupt-pending bit to be set to one if the rectified
input value is high (= 1) under the new source mode."
When the interrupt type is changed in the sourcecfg register, the APLIC
device might not set the corresponding pending bit, so the interrupt might
never become pending.
To handle sourcecfg register changes for level-triggered interrupts in MSI
mode, manually set the pending bit for retriggering interrupt so it gets
retriggered if it was already asserted.

The device tree property 'xlnx,kind-of-intr' is sanity checked that the
bitmask contains only set bits which are in the range of the number of
interrupts supported by the controller.
The check is done by shifting the mask right by the number of supported
interrupts and checking the result for zero.
The data type of the mask is u32 and the number of supported interrupts is
up to 32. In case of 32 interrupts the shift is out of bounds, resulting in
a mismatch warning. The out of bounds condition is also reported by UBSAN:
UBSAN: shift-out-of-bounds in irq-xilinx-intc.c:332:22
shift exponent 32 is too large for 32-bit type 'unsigned int'
Fix it by promoting the mask to u64 for the test.

bcachefs_metadata_version_disk_accounting_v2 erroneously had padding
bytes in disk_accounting_key, which is a problem because we have to
guarantee that all unused bytes in disk_accounting_key are zeroed.
Fortunately 6.11 isn't out yet, so it's cheap to fix this by spinning a
new version.

"There are two more changes to the syscall.tbl conversion: the
'__NR_newfstat' in the previous bugfix was a mistake and gets reverted
now, after triple-checking that the contents are now back to what they
were on all architectures. The __NR_nfsservctl definition is not
really needed but came up in the same discussion as it had previously
been defined in uapi/asm-generic/unistd.h and tested for in user
space.
There are a few more symbols that used to be defined in the old
unistd.h file, but that are never defined on any other architecture
using syscall.tbl format. These used to be needed inside of the
kernel:
__NR_syscalls
__NR_arch_specific_syscall
__NR3264_*
Searching for these on https://codesearch.debian.net/ shows a few
packages (rustc, golang, clamav, libseccomp, librsvg, strace) that
duplicate all the macros from asm/unistd.h, but nothing that actually
uses the macros, so I concluded that they are fine to omit after all"
