Merge trivial x86 code generation annoyances

 - Introduce helper macros for clang asm input problems

 - use said macros to improve trivially stupid code generation issues in
   bitops and array_index_mask_nospec

 - also improve codegen with 32-bit array index comparisons

None of these really matter, but I look at code generation and profiles
fairly regularly, and these misfeatures caused the generated code to
look really odd and distract from the real issues.

* branch 'x86-codegen' of local tree:
  x86: improve bitop code generation with clang
  x86: improve array_index_mask_nospec() code generation
  clang: work around asm input constraint problems

This uses the new ASM_INPUT_RM macro to avoid the bad code generation
issue that clang has with more generic asm inputs.

This ends up avoiding generating code like this:

 	mov    %r10,(%rsp)
 	tzcnt  (%rsp),%rcx

which now becomes just

 	tzcnt  %r10,%rcx

and in the process ends up also removing a few unnecessary stack frames
when the only use was that pointless "asm uses memory location off stack".

Don't force the inputs to be 'unsigned long', when the comparison can
easily be done in 32-bit if that's more appropriate.

Note that while we can look at the inputs to choose an appropriate size
for the compare instruction, the output is fixed at 'unsigned long'.
That's not technically optimal either, since a 32-bit 'sbbl' would often
be sufficient.

But for the outgoing mask we don't know how the mask ends up being used
(ie we have uses that have an incoming 32-bit array index, but end up
using the mask for other things).  That said, it only costs the extra
REX prefix to always generate the 64-bit mask.

[ A 'sbbl' also always technically generates a 64-bit mask, but with the
  upper 32 bits clear: that's fine for when the incoming index that will
  be masked is already 32-bit, but not if you use the mask to mask a
  pointer afterwards, like the file table lookup does ]

Work around clang problems with asm constraints that have multiple
possibilities, particularly "g" and "rm".

Clang seems to turn inputs like that into the most generic form, which
is the memory input - but to make matters worse, clang won't even use a
possible original memory location, but will spill the value to stack,
and use the stack for the asm input.

See

  https://github.com/llvm/llvm-project/issues/20571#issuecomment-980933442

for some explanation of why clang has this strange behavior, but the end
result is that "g" and "rm" really end up generating horrid code.

Our applications, built on Elasticsearch[0], frequently create and
delete files.  These applications operate within containers, some with a
memory limit exceeding 100GB.  Over prolonged periods, the accumulation
of negative dentries within these containers can amount to tens of
gigabytes.

Upon container exit, directories are deleted.  However, due to the
numerous associated dentries, this process can be time-consuming.  Our
users have expressed frustration with this prolonged exit duration,
which constitutes our first issue.

Simultaneously, other processes may attempt to access the parent
directory of the Elasticsearch directories.  Since the task responsible
for deleting the dentries holds the inode lock, processes attempting
directory lookup experience significant delays.  This issue, our second
problem, is easily demonstrated:

  - Task 1 generates negative dentries:
  $ pwd
  ~/test
  $ mkdir es && cd es/ && ./create_and_delete_files.sh

  [ After generating tens of GB dentries ]

  $ cd ~/test && rm -rf es

  [ It will take a long duration to finish ]

  - Task 2 attempts to lookup the 'test/' directory
  $ pwd
  ~/test
  $ ls

  The 'ls' command in Task 2 experiences prolonged execution as Task 1
  is deleting the dentries.

We've devised a solution to address both issues by deleting associated
dentry when removing a file.  Interestingly, we've noted that a similar
patch was proposed years ago[1], although it was rejected citing the
absence of tangible issues caused by negative dentries.  Given our
current challenges, we're resubmitting the proposal.  All relevant
stakeholders from previous discussions have been included for reference.

Some alternative solutions are also under discussion[2][3], such as
shrinking child dentries outside of the parent inode lock or even
asynchronously shrinking child dentries.  However, given the
straightforward nature of the current solution, I believe this approach
is still necessary.

[ NOTE! This is a pretty fundamental change in how we deal with
  unlinking dentries, and it doesn't change the fact that you can have
  lots of negative dentries from just doing negative lookups.

  But the kernel test robot is at least initially happy with this from a
  performance angle, so I'm applying this ASAP just to get more testing
  and as a "known fix for an issue people hit in real life".

  Put another way: we should still look at the alternatives, and this
  patch may get reverted if somebody finds a performance regression on
  some other load.       - Linus ]

Merge tag 'perf-tools-for-v6.10-1-2024-05-21' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools updates from Arnaldo Carvalho de Melo:
 "General:

   - Integrate the shellcheck utility with the build of perf to allow
     catching shell problems early in areas such as 'perf test', 'perf
     trace' scrape scripts, etc

   - Add 'uretprobe' variant in the 'perf bench uprobe' tool

   - Add script to run instances of 'perf script' in parallel

   - Allow parsing tracepoint names that start with digits, such as
     9p/9p_client_req, etc. Make sure 'perf test' tests it even on
     systems where those tracepoints aren't available

   - Add Kan Liang to MAINTAINERS as a perf tools reviewer

   - Add support for using the 'capstone' disassembler library in
     various tools, such as 'perf script' and 'perf annotate'. This is
     an alternative for the use of the 'xed' and 'objdump' disassemblers

  Data-type profiling improvements:

   - Resolve types for a->b->c by backtracking the assignments until it
     finds DWARF info for one of those members

   - Support for global variables, keeping a cache to speed up lookups

   - Handle the 'call' instruction, dealing with effects on registers
     and handling its return when tracking register data types

   - Handle x86's segment based addressing like %gs:0x28, to support
     things like per CPU variables, the stack canary, etc

   - Data-type profiling got big speedups when using capstone for
     disassembling. The objdump outoput parsing method is left as a
     fallback when capstone fails or isn't available. There are patches
     posted for 6.11 that to use a LLVM disassembler

   - Support event group display in the TUI when annotating types with
     --data-type, for instance to show memory load and store events for
     the data type fields

   - Optimize the 'perf annotate' data structures, reducing memory usage

   - Add a initial 'perf test' for 'perf annotate', checking that a
     target symbol appears on the output, specifying objdump via the
     command line, etc

  Vendor Events:

   - Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand
     Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra
     Forest, Sky Lake X, Sky Lake and Snow Ridge X. Remove info metrics
     erroneously in TopdownL1

   - Add AMD's Zen 5 core and uncore events and metrics. Those come from
     the "Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh
     Processors" document, with events that capture information on op
     dispatch, execution and retirement, branch prediction, L1 and L2
     cache activity, TLB activity, etc

   - Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/
     AmpereOneX

  Miscellaneous:

   - Sync header copies with the kernel sources

   - Move some header copies used only for generating translation string
     tables for ioctl cmds and other syscall integer arguments to a new
     directory under tools/perf/beauty/, to separate from copies in
     tools/include/ that are used to build the tools

   - Introduce scrape script for several syscall 'flags'/'mask'
     arguments

   - Improve cpumap utilization, fixing up pairing of refcounts, using
     the right iterators (perf_cpu_map__for_each_cpu), etc

   - Give more details about raw event encodings in 'perf list', show
     tracepoint encoding in the detailed output

   - Refactor the DSOs handling code, reducing memory usage

   - Document the BPF event modifier and add a 'perf test' for it

   - Improve the event parser, better error messages and add further
     'perf test's for it

   - Add reference count checking to 'struct comm_str' and 'struct
     mem_info'

   - Make ARM64's 'perf test' entries for the Neoverse N1 more robust

   - Tweak the ARM64's Coresight 'perf test's

   - Improve ARM64's CoreSight ETM version detection and error reporting

   - Fix handling of symbols when using kcore

   - Fix PAI (Processor Activity Instrumentation) counter names for s390
     virtual machines in 'perf report'

   - Fix -g/--call-graph option failure in 'perf sched timehist'

   - Add LIBTRACEEVENT_DIR build option to allow building with
     libtraceevent installed in non-standard directories, such as when
     doing cross builds

   - Various 'perf test' and 'perf bench' fixes

   - Improve 'perf probe' error message for long C++ probe names"

Pull more s390 updates from Alexander Gordeev:

 - Switch read and write software bits for PUDs

 - Add missing hardware bits for PUDs and PMDs

 - Generate unwind information for C modules to fix GDB unwind error for
   vDSO functions

 - Create .build-id links for unstripped vDSO files to enable vDSO
   debugging with symbols

 - Use standard stack frame layout for vDSO generated stack frames to
   manually walk stack frames without DWARF information

 - Rework perf_callchain_user() and arch_stack_walk_user() functions to
   reduce code duplication

 - Skip first stack frame when walking user stack

 - Add basic checks to identify invalid instruction pointers when
   walking stack frames

 - Introduce and use struct stack_frame_vdso_wrapper within vDSO user
   wrapper code to automatically generate an asm-offset define. Also use
   STACK_FRAME_USER_OVERHEAD instead of STACK_FRAME_OVERHEAD to document
   that the code works with user space stack

 - Clear the backchain of the extra stack frame added by the vDSO user
   wrapper code. This allows the user stack walker to detect and skip
   the non-standard stack frame. Without this an incorrect instruction
   pointer would be added to stack traces.

 - Rewrite psw_idle() function in C to ease maintenance and further
   enhancements

 - Remove get_vtimer() function and use get_cpu_timer() instead

 - Mark psw variable in __load_psw_mask() as __unitialized to avoid
   superfluous clearing of PSW

 - Remove obsolete and superfluous comment about removed TIF_FPU flag

 - Replace memzero_explicit() and kfree() with kfree_sensitive() to fix
   warnings reported by Coccinelle

 - Wipe sensitive data and all copies of protected- or secure-keys from
   stack when an IOCTL fails

 - Both do_airq_interrupt() and do_io_interrupt() functions set
   CIF_NOHZ_DELAY flag. Move it in do_io_irq() to simplify the code

 - Provide iucv_alloc_device() and iucv_release_device() helpers, which
   can be used to deduplicate more or less identical IUCV device
   allocation and release code in four different drivers

 - Make use of iucv_alloc_device() and iucv_release_device() helpers to
   get rid of quite some code and also remove a cast to an incompatible
   function (clang W=1)

 - There is no user of iucv_root outside of the core IUCV code left.
   Therefore remove the EXPORT_SYMBOL

 - __apply_alternatives() contains a runtime check which verifies that
   the size of the to be patched code area is even. Convert this to a
   compile time check

 - Increase size of buffers for sending z/VM CP DIAGNOSE X'008' commands
   from 128 to 240

 - Do not accept z/VM CP DIAGNOSE X'008' commands longer than maximally
   allowed

 - Use correct defines IPL_BP_NVME_LEN and IPL_BP0_NVME_LEN instead of
   IPL_BP_FCP_LEN and IPL_BP0_FCP_LEN ones to initialize NVMe reIPL
   block on 'scp_data' sysfs attribute update

 - Initialize the correct fields of the NVMe dump block, which were
   confused with FCP fields

 - Refactor macros for 'scp_data' (re-)IPL sysfs attribute to reduce
   code duplication

 - Introduce 'scp_data' sysfs attribute for dump IPL to allow tools such
   as dumpconf passing additional kernel command line parameters to a
   stand-alone dumper

 - Rework the CPACF query functions to use the correct RRE or RRF
   instruction formats and set instruction register fields correctly

 - Instead of calling BUG() at runtime force a link error during compile
   when a unsupported opcode is used with __cpacf_query() or
   __cpacf_check_opcode() functions

 - Fix a crash in ap_parse_bitmap_str() function on /sys/bus/ap/apmask
   or /sys/bus/ap/aqmask sysfs file update with a relative mask value

 - Fix "bindings complete" udev event which should be sent once all AP
   devices have been bound to device drivers and again when unbind/bind
   actions take place and all AP devices are bound again

 - Facility list alt_stfle_fac_list is nowhere used in the decompressor,
   therefore remove it there

 - Remove custom kprobes insn slot allocator in favour of the standard
   module_alloc() one, since kernel image and module areas are located
   within 4GB

 - Use kvcalloc() instead of kvmalloc_array() in zcrypt driver to avoid
   calling memset() with a large byte count and get rid of the sparse
   warning as result

 "Enumeration:

   - Skip E820 checks for MCFG ECAM regions for new (2016+) machines,
     since there's no requirement to describe them in E820 and some
     platforms require ECAM to work (Bjorn Helgaas)

   - Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific (Damien
     Le Moal)

   - Remove last user and pci_enable_device_io() (Heiner Kallweit)

   - Wait for Link Training==0 to avoid possible race (Ilpo Järvinen)

   - Skip waiting for devices that have been disconnected while
     suspended (Ilpo Järvinen)

  MSI:

   - Remove unused IMS (Interrupt Message Store) support (Bjorn Helgaas)

  Error handling:

   - Mask Genesys GL975x SD host controller Replay Timer Timeout
     correctable errors caused by a hardware defect; the errors cause

  DOE:

   - Support DOE Discovery Version 2 (Alexey Kardashevskiy)

  Endpoint framework:

   - Set endpoint BAR to be 64-bit if the driver says that's all the

     (Niklas Cassel)

   - Simplify endpoint BAR allocation and setting interfaces (Niklas
     Cassel)

  Cadence PCIe controller driver:

   - Drop DT binding redundant msi-parent and pci-bus.yaml (Krzysztof

     was masked incorrectly (Rick Wertenbroek)

  Synopsys DesignWare PCIe controller driver:

   - Restructure DBI register access to accommodate devices where this
     requires Refclk to be active (Manivannan Sadhasivam)

   - Remove the deinit() callback, which was only need by the
     pcie-rcar-gen4, and do it directly in that driver (Manivannan
     Sadhasivam)

   - Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean
     up things like eDMA (Manivannan Sadhasivam)

   - Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel
     to dw_pcie_ep_init() (Manivannan Sadhasivam)

   - Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
     reflect the actual functionality (Manivannan Sadhasivam)

   - Call dw_pcie_ep_init_registers() directly from all the glue
     drivers, not just those that require active Refclk from the host
     (Manivannan Sadhasivam)

   - Remove the "core_init_notifier" flag, which was an obscure way for
     glue drivers to indicate that they depend on Refclk from the host
     (Manivannan Sadhasivam)

Pull trusted keys fixes from Jarkko Sakkinen:
 "These are two bugs I found from trusted keys while working on a new
  RSA key type for TPM2. Both originate form v5.13.

  The memory leak is more crucial but I don't think it is either good
  idea if kernel throws WARN when ASN.1 parser fails, even if it is
  related to programming error, as it is not that mature code yet.

  There's at least two WARN's in that code but I picked just the one
  more likely to trigger. Planning to fix the other one too over time"

Previous patch modified the standard used by acpi_gpiochip_find()
to match device nodes. Using the device node set in gc->gpiodev->d-
ev instead of gc->parent.

However, there is a situation in gpio-dwapb where the GPIO device
driver will set gc->fwnode for each port corresponding to a child
node under a GPIO device, so gc->gpiodev->dev will be assigned the
value of each child node in gpiochip_add_data().

gpio-dwapb.c:
128,31 static int dwapb_gpio_add_port(struct dwapb_gpio *gpio,
			       struct dwapb_port_property *pp,
			       unsigned int offs);
port->gc.fwnode = pp->fwnode;

693,39 static int dwapb_gpio_probe;
err = dwapb_gpio_add_port(gpio, &pdata->properties[i], i);

When other drivers request GPIO pin resources through the GPIO device
node provided by ACPI (corresponding to the parent node), the change
of the matching object to gc->gpiodev->dev in acpi_gpiochip_find()
only allows finding the value of each port (child node), resulting
in a failed request.

Reapply the condition of using gc->parent for match in acpi_gpio-
chip_find() in the code can compatible with the problem of gpio-dwapb,
and will not affect the two cases mentioned in the patch:
1. There is no setting for gc->fwnode.
2. The case that depends on using gc->fwnode for match.

Fixes: 5062e4c1 ("gpiolib: acpi: use the fwnode in acpi_gpiochip_find()")
Fixes: 067dbc1e ("gpiolib: acpi: Don't use GPIO chip fwnode in acpi_gpiochip_find()")
