perf intel-pt: Fix unassigned instruction op (discovered by MemorySanitizer)
MemorySanitizer discovered instances where the instruction op value was
not assigned.:
WARNING: MemorySanitizer: use-of-uninitialized-value
#0 0x5581c00a76b3 in intel_pt_sample_flags tools/perf/util/intel-pt.c:1527:17
Uninitialized value was stored to memory at
#0 0x5581c005ddf8 in intel_pt_walk_insn tools/perf/util/intel-pt-decoder/intel-pt-decoder.c:1256:25
The op value is used to set branch flags for branch instructions
encountered when walking the code, so fix by setting op to
INTEL_PT_OP_OTHER in other cases.

perf annotate: Update DSO binary type when trying build-id
dso__disassemble_filename() tries to get the filename for objdump (or
capstone) using build-id. But I found sometimes it didn't disassemble
some functions.
It turned out that those functions belong to a DSO which has no binary
type set. It seems it sets the binary type for some special files only
- like kernel (kallsyms or kcore) or BPF images. And there's a logic to
skip dso with DSO_BINARY_TYPE__NOT_FOUND.
As it's checked the build-id cache link, it should set the binary type
as DSO_BINARY_TYPE__BUILD_ID_CACHE.

perf annotate: Fallback disassemble to objdump when capstone fails
I found some cases that capstone failed to disassemble. Probably my capstone is an old version but anyway there's a chance it can fail. And then it silently stopped in the middle. In my case, it didn't understand "RDPKRU" instruction. Let's check if the capstone disassemble reached the end of the function and fallback to objdump if not.

perf parse-events: Prefer sysfs/JSON hardware events over legacy
It was requested that RISC-V be able to add events to the perf tool so the PMU driver didn't need to map legacy events to config encodings: https://lore.kernel.org/lkml/20240217005738.3744121-1-atishp@rivosinc.com/ This change makes the priority of events specified without a PMU the same as those specified with a PMU, namely sysfs and JSON events are checked first before using the legacy encoding. The hw_term is made more generic as a hardware_event that encodes a pair of string and int value, allowing parse_events_multi_pmu_add to fall back on a known encoding when the sysfs/JSON adding fails for core events. As this covers PE_VALUE_SYM_HW, that token is removed and related code simplified.

perf parse-events: Legacy cache names on all PMUs and lower priority
Prior behavior is to not look for legacy cache names in sysfs/JSON and to create events on all core PMUs. New behavior is to look for sysfs/JSON events first on all PMUs, for core PMUs add a legacy event if the sysfs/JSON event isn't present. This is done so that there is consistency with how event names in terms are handled and their prioritization of sysfs/JSON over legacy. It may make sense to use a legacy cache event name as an event name on a non-core PMU so we should allow it.

perf parse-events: Directly pass PMU to parse_events_add_pmu()
Avoid passing the name of a PMU then finding it again, just directly pass the PMU. parse_events_multi_pmu_add_or_add_pmu() is the only version that needs to find a PMU, so move the find there. Remove the error message as parse_events_multi_pmu_add_or_add_pmu will given an error at the end when a name isn't either a PMU name or event name. Without the error message being created the location in the input parameter (loc) can be removed.

perf parse-events: Factor out '<event_or_pmu>/.../' parsing
Factor out the case of an event or PMU name followed by a slash based term list. This is with a view to sharing the code with new legacy hardware parsing. Use early return to reduce indentation in the code. Make parse_events_add_pmu static now it doesn't need sharing with parse-events.y.

perf scripts python: Add a script to run instances of 'perf script' in parallel
Add a Python script to run a perf script command multiple times in
parallel, using perf script options --cpu and --time so that each job
processes a different chunk of the data.
Extend perf script tests to test also the new script.
The script supports the use of normal 'perf script' options like
--dlfilter and --script, so that the benefit of running parallel jobs
naturally extends to them also. In addition, a command can be provided
(refer --pipe-to option) to pipe standard output to a custom command.
Refer to the script's own help text at the end of the patch for more
details.
The script is useful for Intel PT traces, that can be efficiently
decoded by 'perf script' when split by CPU and/or time ranges. Running
jobs in parallel can decrease the overall decoding time.
Committer testing:
Ian reported that shellcheck found some issues, I installed it as there
are no warnings about it not being available, but when available it
fails the build with:

* Clean up SVM's enter/exit assembly code so that it can be compiled
without OBJECT_FILES_NON_STANDARD. This fixes a warning
"Unpatched return thunk in use. This should not happen!" when running
KVM selftests.
* Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure where KVM
would allow userspace to refresh the cache with a bogus GPA. The bug has
existed for quite some time, but was exposed by a new sanity check added in
6.9 (to ensure a cache is either GPA-based or HVA-based).
* Drop an unused param from gfn_to_pfn_cache_invalidate_start() that got left
behind during a 6.9 cleanup.
* Fix a math goof in x86's hugepage logic for KVM_SET_MEMORY_ATTRIBUTES that
results in an array overflow (detected by KASAN).
* Fix a bug where KVM incorrectly clears root_role.direct when userspace sets
guest CPUID.
* Fix a dirty logging bug in the where KVM fails to write-protect SPTEs used
by a nested guest, if KVM is using Page-Modification Logging and the nested
hypervisor is NOT using EPT.
x86 PMU:
* Drop support for virtualizing adaptive PEBS, as KVM's implementation is
architecturally broken without an obvious/easy path forward, and because
exposing adaptive PEBS can leak host LBRs to the guest, i.e. can leak
host kernel addresses to the guest.
* Set the enable bits for general purpose counters in PERF_GLOBAL_CTRL at
RESET time, as done by both Intel and AMD processors.
* Disable LBR virtualization on CPUs that don't support LBR callstacks, as
KVM unconditionally uses PERF_SAMPLE_BRANCH_CALL_STACK when creating the
perf event, and would fail on such CPUs.
Tests:
* Fix a flaw in the max_guest_memory selftest that results in it exhausting
the supply of ucall structures when run with more than 256 vCPUs.
* Mark KVM_MEM_READONLY as supported for RISC-V in set_memory_region_test.

- Changes to disable some broken PMU virtualization (see below for

A couple clk driver fixes, a build fix, and a deadlock fix.
- Mediatek mt7988 has broken PCIe because the wrong parent is used
- Mediatek clk drivers may deadlock when registering their clks because
the clk provider device is repeatedly runtime PM resumed and
suspended during probe and clk registration. Resuming the clk
provider device deadlocks with an ABBA deadlock due to genpd_lock and
the clk prepare_lock. The fix is to keep the device runtime resumed
while registering clks.
- Another runtime PM related deadlock, this time with disabling unused
clks during late init. We get an ABBA deadlock where a device is
runtime PM resuming (or suspending) while the disabling of unused
clks is happening in parallel. That runtime PM action calls into the
clk framework and tries to grab the clk prepare_lock while the
disabling of unused clks holds the prepare_lock and is waiting for
that runtime PM action to complete. The fix is to runtime resume all
the clk provider devices before grabbing the clk prepare_lock during
disable unused.
- A build fix to provide an empty devm_clk_rate_exclusive_get()
function when CONFIG_COMMON_CLK=n

fs/9p: fixes regressions in 6.9
This series contains a reversion of one of the original 6.9 patches which seems to have been the cause of most of the instability. It also incorporates several fixes to legacy support and cache fixes. There are few additional changes to improve stability, but I want another week of testing before sending them upstream.

arm64 fixes:
- Fix a kernel fault during page table walking in huge_pte_alloc() with PTABLE_LEVELS=5 due to using p4d_offset() instead of p4d_alloc() - head.S fix and cleanup to disable the MMU before toggling the HCR_EL2.E2H bit when entering the kernel with the MMU on from the EFI stub. Changing this bit (currently from VHE to nVHE) causes some system registers as well as page table descriptors to be interpreted differently, potentially resulting in spurious MMU faults - Fix translation fault in swsusp_save() accessing MEMBLOCK_NOMAP memory ranges due to kernel_page_present() returning true in most configurations other than rodata_full == true, CONFIG_DEBUG_PAGEALLOC=y or CONFIG_KFENCE=y -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmYirgQACgkQa9axLQDI XvFbhQ/+MD6ziCPeVxpYNW44rWrG0p3VQ1uZniALSH2rsauNqSZiwGkXJskC5jmj rgh2RF5reAokDeDNPSNlBzSpXvjknJNb4cJwYZzzhoOF+P3Oi0t6LQOeh07mi7sM SjnklzoPWa88i5SjTQGmqnJTMe3okdFxHEsT+0Szuu1UZqOC63/Nf/LlBvAFcR0x CP5I5701+1tlgPiW9YnaBBKMuPFqdYVtBsG1BLsUFBhkKr39vcmYfwo0gGzThJuP XmvL3zWR53ec9yksBElXgWy38J0ixOxsZlHe1dQaxyQeUMK8ioFpsf/OdXRvs9nb u3ezwRsgByZ4X+4Y1LwGHnYTOuKqOg/FDNUZAcg3ZDY2AOF4c7mPNmquEQJYaM5J Ac//IRGAdZxZO6An7UrTv1lESjvsJ/8PosbyM5CPu+kIUwezvBL2xmJ22lTOmKrz mtHIzH7pc0DfGvlu8czizH1oCuW20YviwNMb7PxzsSkIkDJsuHloefhcrmOm8BCM LD5DfgzwONr6nlEMPdbRZcRz52RZAXgvgJml/qU4eZxvT8h8sQbgm/KiEBjuC/BO 4TgJ1z8w1Svu8ulLMVtLj0+zgtRlMCHHldiBVUIXZ5vvsJgtM9ALgTWGl05RLquu EL4j3izYaFhCHY2PHwoMCWRh5We68xgU8r8mgq/cO7mEJAj3JCM= =UvpI -----END PGP SIGNATURE----- Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Catalin Marinas: - Fix a kernel fault during page table walking in huge_pte_alloc() with PTABLE_LEVELS=5 due to using p4d_offset() instead of p4d_alloc() - head.S fix and cleanup to disable the MMU before toggling the HCR_EL2.E2H bit when entering the kernel with the MMU on from the EFI stub.

Bootconfig fixes for v6.9-rc4:
- Fix potential static_command_line buffer overrun. Currently we allocate the memory for static_command_line based on "boot_command_line", but it will copy "command_line" into it. So we use the length of "command_line" instead of "boot_command_line" (as previously we did). - Use memblock_free_late() in xbc_exit() instead of memblock_free() after the buddy system is initialized. - Fix a kerneldoc warning. -----BEGIN PGP SIGNATURE----- iQFPBAABCgA5FiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmYgN1kbHG1hc2FtaS5o aXJhbWF0c3VAZ21haWwuY29tAAoJENv7B78FKz8b/yEH/1FFgb7UJDtQLbtHl5/b bcxLbSzfb/N37Bc+sE/AKZYrt5QAMjaOmdtzQz9kdLtycxWcQinne4jqGxd6zfTU UIisfDjEZr46/Rs5sJg+5i8wWrud1TJOmlMsqiSVcorl0f/wE4S7PqgYXRNWZ0p+ KipjuCCV43ITmVjsiq2NxfZGDaWzow/EJXwZzpQkJE1zaU13w2nzgzg64JW3f/lf Dx/o9jlYEoLkCjiQJ6XaRuTpHbPP1grozSMbvE3z1WnxCaiFHlzXGi6WUhto+pTu vt/pUrIFYE7k0IFHAVEgBjOkfCm5y9FwOdPLqwy3harQ5ek9D6h6bFnDhbZw7I27 6V8= =e2c5 -----END PGP SIGNATURE----- Merge tag 'bootconfig-fixes-v6.9-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull bootconfig fixes from Masami Hiramatsu: - Fix potential static_command_line buffer overrun.
