      Pull cxl fixes from Dan Williams:
       "A collection of significant fixes for the CXL subsystem.
      
        The largest change in this set, that bordered on "new development", is
        the fix for the fact that the location of the new qos_class attribute
        did not match the Documentation. The fix ends up deleting more code
        than it added, and it has a new unit test to backstop basic errors in
        this interface going forward. So the "red-diff" and unit test saved
        the "rip it out and try again" response.
      
        In contrast, the new notification path for firmware reported CXL
        errors (CXL CPER notifications) has a locking context bug that can not
        be fixed with a red-diff. Given where the release cycle stands, it is
        not comfortable to squeeze in that fix in these waning days. So, that
        receives the "back it out and try again later" treatment.
      
        There is a regression fix in the code that establishes memory NUMA
        nodes for platform CXL regions. That has an ack from x86 folks. There
        are a couple more fixups for Linux to understand (reassemble) CXL
        regions instantiated by platform firmware. The policy around platforms
        that do not match host-physical-address with system-physical-address
        (i.e. systems that have an address translation mechanism between the
        address range reported in the ACPI CEDT.CFMWS and endpoint decoders)
        has been softened to abort driver load rather than teardown the memory
        range (can cause system hangs). Lastly, there is a robustness /
        regression fix for cases where the driver would previously continue in
        the face of error, and a fixup for PCI error notification handling.
      
        Summary:
      
         - Fix NUMA initialization from ACPI CEDT.CFMWS
      
         - Fix region assembly failures due to async init order
      
         - Fix / simplify export of qos_class information
      
         - Fix cxl_acpi initialization vs single-window-init failures
      
         - Fix handling of repeated 'pci_channel_io_frozen' notifications
      
         - Workaround platforms that violate host-physical-address ==
           system-physical address assumptions
      
         - Defer CXL CPER notification handling to v6.9"

      dm-integrity, dm-verity: reduce stack usage for recheck · 66ad2fbc
      Arnd Bergmann authored
      The newly added integrity_recheck() function has another larger stack
      allocation, just like its caller integrity_metadata(). When it gets
      inlined, the combination of the two exceeds the warning limit for 32-bit
      architectures and possibly risks an overflow when this is called from
      a deep call chain through a file system:
      
      drivers/md/dm-integrity.c:1767:13: error: stack frame size (1048) exceeds limit (1024) in 'integrity_metadata' [-Werror,-Wframe-larger-than]
       1767 | static void integrity_metadata(struct work_struct *w)
      
      Since the caller at this point is done using its checksum buffer,
      just reuse the same buffer in the new function to avoid the double
      allocation.
      
      [Mikulas: add "noinline" to integrity_recheck and verity_recheck.
      These functions are only called on error, so they shouldn't bloat the
      stack frame or code size of the caller.]

      i2c: imx: when being a target, mark the last read as processed · 87aec499
      Corey Minyard authored
      When being a target, NAK from the controller means that all bytes have
      been transferred. So, the last byte needs also to be marked as
      'processed'. Otherwise index registers of backends may not increase.

      Pull ata fixes from Niklas Cassel:
      
       - Do not try to set a sleeping device to standby. Sleep is a deeper
         sleep state than standby, and needs a reset to wake up the drive. A
         system resume will reset the port. Sending a command other than reset
         to a sleeping device is not wise, as the command will timeout (Damien
         Le Moal)
      
       - Do not try to put a device to standby twice during system shutdown.
         ata_dev_power_set_standby() is currently called twice during
         shutdown, once after the scsi device is removed, and another when
         ata_pci_shutdown_one() executes. Modify ata_dev_power_set_standby()
         to do nothing if the device is already in standby (Damien Le Moal)
      
       - Add a quirk for ASM1064 to fixup the number of implemented ports. We
         probe all ports that the hardware reports to be implemented. Probing
         ports that are not implemented causes significantly increased boot
         time (Andrey Jr. Melnikov)
      
       - Fix error handling for the ahci_ceva driver. Ensure that the
         ahci_ceva driver does a proper cleanup of its resources in the error
         path (Radhey Shyam Pandey)

      LoongArch: KVM: Streamline kvm_check_cpucfg() and improve comments · f0f5c489
      WANG Xuerui authored
      All the checks currently done in kvm_check_cpucfg can be realized with
      early returns, so just do that to avoid extra cognitive burden related
      to the return value handling.
      
      While at it, clean up comments of _kvm_get_cpucfg_mask() and
      kvm_check_cpucfg(), by removing comments that are merely restatement of
      the code nearby, and paraphrasing the rest so they read more natural for
      English speakers (that likely are not familiar with the actual Chinese-
      influenced grammar).
      
      No functional changes intended.

      The function is not actually a getter of guest CPUCFG, but rather
      validation of the input CPUCFG ID plus information about the supported
      bit flags of that CPUCFG leaf. So rename it to avoid confusion.

      WANG Xuerui authored
      The range check for the CPUCFG ID is wrong (should have been a ||
      instead of &&) and useless in effect, so fix the obvious mistake.
      
      Furthermore, the juggling of the temp return value is unnecessary,
      because it is semantically equivalent and more readable to just
      return at every switch case's end. This is done too to avoid potential
      bugs in the future related to the unwanted complexity.
      
      Also, the return value of _kvm_get_cpucfg is meant to be checked, but
      this was not done, so bad CPUCFG IDs wrongly fall back to the default
      case and 0 is incorrectly returned; check the return value to fix the
      UAPI behavior.
      
      While at it, also remove the redundant range check in kvm_check_cpucfg,
      because out-of-range CPUCFG IDs are already rejected by the -EINVAL
      as returned by _kvm_get_cpucfg().

      LoongArch: Call early_init_fdt_scan_reserved_mem() earlier · 9fa304b9
      Huacai Chen authored
      The unflatten_and_copy_device_tree() function contains a call to
      memblock_alloc(). This means that memblock is allocating memory before
      any of the reserved memory regions are set aside in the arch_mem_init()
      function which calls early_init_fdt_scan_reserved_mem(). Therefore,
      there is a possibility for memblock to allocate from any of the
      reserved memory regions.
      
      Hence, move the call to early_init_fdt_scan_reserved_mem() to be earlier
      in the init sequence, so that the reserved memory regions are set aside
      before any allocations are done using memblock.

      nouveau: add an ioctl to report vram usage · 72fa02fd
      Dave Airlie authored
      This reports the currently used vram allocations.
      
      userspace using this has been proposed for nvk, but
      it's a rather trivial uapi addition.

      This returns the BAR resources size so userspace can make
      decisions based on rebar support.

      nouveau/gsp: add kconfig option to enable GSP paths by default · 1d492944
      Dave Airlie authored
      Turing and Ampere will continue to use the old paths by default,
      but we should allow distros to decide what the policy is.
