      Pull remoteproc updates from Bjorn Andersson:
       "This adds support for controlling the PRU and R5F clusters on the TI
        AM64x, the remote processor in i.MX7ULP, i.MX8MN/P and i.MX8ULP NXP
        and the audio, compute and modem remoteprocs in the Qualcomm SC8180x
        platform.
      
        It fixes improper ordering of cdev and device creation of the
        remoteproc control interface and it fixes resource leaks in the error
        handling path of rproc_add() and the Qualcomm modem and wifi
        remoteproc drivers.
      
        Lastly it fixes a few build warnings and replace the dummy parameter
        passed in the mailbox api of the stm32 driver to something not living
        on the stack"

         - several improvements to the core gpiolib and the sysfs interface
           code from Andy Shevchenko
      
         - conversion of the gpio-xilinx driver to using the bitmap API +
           improvements of suspend/resume handling + minor tweaks
      
         - convert the gpio-stmpe to using devres helpers exclusively in probe
           for improved robustness
      
         - updates for the generic gpio-regmap driver
      
         - updates for the gpio-dwapb driver

      Input: joydev - prevent use of not validated data in JSIOCSBTNMAP ioctl · f8f84af5
      Alexander Larkin authored
      Even though we validate user-provided inputs we then traverse past
      validated data when applying the new map. The issue was originally
      discovered by Murray McAllister with this simple POC (if the following
      is executed by an unprivileged user it will instantly panic the system):
      
      int main(void) {
      	int fd, ret;
      	unsigned int buffer[10000];
      
      	fd = open("/dev/input/js0", O_RDONLY);
      	if (fd == -1)
      		printf("Error opening file\n");
      
      	ret = ioctl(fd, JSIOCSBTNMAP & ~IOCSIZE_MASK, &buffer);
      	printf("%d\n", ret);
      }
      
      The solution is to traverse internal buffer which is guaranteed to only
      contain valid date when constructing the map.

      iov_iter: remove uaccess_kernel() warning from iov_iter_init() · a180bd1d
      Linus Torvalds authored
      This warning was there to catch any architectures that still use
      CONFIG_SET_FS, and that would mis-use iov_iter_init() for anything that
      wasn't a proper user space pointer.  So that
      
              WARN_ON_ONCE(uaccess_kernel());
      
      makes perfect conceptual sense: you really shouldn't use a kernel
      pointer with set_fs(KERNEL_DS) and then pass it to iov_iter_init().
      
      HOWEVER.
      
      Guenter Roeck reports that this warning actually triggers in no-mmu
      configurations of both ARM and m68k.  And the reason isn't that they
      pass in a kernel pointer under set_fs(KERNEL_DS) at all: the reason is
      that in those configurations, "uaccess_kernel()" is simply not reliable.
      
      Those no-mmu setups set USER_DS and KERNEL_DS to the same values, so you
      can't test for the difference.
      
      In particular, the no-mmu case for ARM does
      
         #define USER_DS                 KERNEL_DS
         #define uaccess_kernel()        (true)
      
      so USER_DS and KERNEL_DS have the same value, and uaccess_kernel() is
      always trivially true.
      
      The m68k case is slightly different and not quite as obvious.  It does
      (spread out over multiple header files just to be extra exciting:
      asm/processor.h, asm/segment.h and asm-generic/uaccess.h):
      
         #define TASK_SIZE       (0xFFFFFFFFUL)
         #define USER_DS         MAKE_MM_SEG(TASK_SIZE)
         #define KERNEL_DS       MAKE_MM_SEG(~0UL)
         #define get_fs()        (current_thread_info()->addr_limit)
         #define uaccess_kernel() (get_fs().seg == KERNEL_DS.seg)
      
      but the end result is the same: uaccess_kernel() will always be true,
      because USER_DS and KERNEL_DS end up having the same value, even if that
      value is defined differently.
      
      This is very arguably a misfeature in those implementations, but in the
      end we don't really care.  All modern architectures have gotten rid of
      set_fs() already, and generic kernel code never uses it.  And while the
      sanity check was a nice idea, an architecture would have to go the extra
      mile to actually break this.
      
      So this well-intentioned warning isn't really all that likely to find
      anything but these known false positives, and as such just isn't worth
      maintaining.

       "Fix arm crashes caused by holes in the memory map.
      
        The coordination between freeing of unused memory map, pfn_valid() and
        core mm assumptions about validity of the memory map in various ranges
        was not designed for complex layouts of the physical memory with a lot
        of holes all over the place.
      
        Kefen Wang reported crashes in move_freepages() on a system with the
        following memory layout [1]:
      
      	node 0: [mem 0x0000000080a00000-0x00000000855fffff]
      	node 0: [mem 0x0000000086a00000-0x0000000087dfffff]

      	node 0: [mem 0x000000008e300000-0x000000008ecfffff]
      	node 0: [mem 0x0000000090d00000-0x00000000bfffffff]

      	node 0: [mem 0x00000000fda00000-0x00000000ffffefff]
      
        These crashes can be mitigated by enabling CONFIG_HOLES_IN_ZONE on ARM
        and essentially turning pfn_valid_within() to pfn_valid() instead of
        having it hardwired to 1 on that architecture, but this would require
        to keep CONFIG_HOLES_IN_ZONE solely for this purpose.
      
        A cleaner approach is to update ARM's implementation of pfn_valid() to
        take into accounting rounding of the freed memory map to pageblock
        boundaries and make sure it returns true for PFNs that have memory map
        entries even if there is no physical memory backing those PFNs"

      Linus Torvalds authored
      Pull CXL (Compute Express Link) updates from Dan Williams:
       "This subsystem is still in the build-out phase as the bulk of the
        update is improvements to enumeration and fleshing out the device
        model. In terms of new features, more mailbox commands have been added
        to the allowed-list in support of persistent memory provisioning
        support targeting v5.15.
      
        The critical update from an enumeration perspective is support for the
        CXL Fixed Memory Window Structure that indicates to Linux which system
        physical address ranges decode to the CXL Host Bridges in the system.
        This allows the driver to detect which address ranges have been mapped
        by firmware and what address ranges are available for future hotplug.
      
        So, again, mostly skeleton this round, with more meat targeting v5.15.
      
        Summary:
      
         - Add support for the CXL Fixed Memory Window Structure, a recent
           extension of the ACPI CEDT (CXL Early Discovery Table)
      
         - Add infrastructure for component registers
      
         - Add HDM (Host-managed device memory) decoder definitions
      
         - Define a device model for an HDM decoder tree
      
         - Bridge CXL persistent memory capabilities to an NVDIMM bus /
           device-model
      
         - Switch to fine grained mapping of CXL MMIO registers to allow
           different drivers / system software to own individual register
           blocks
      
         - Enable media provisioning commands, and publish the label storage
           area size in sysfs
      
         - Miscellaneous cleanups and fixes"

      scsi: blkcg: Fix application ID config options · d2500a0c
      Martin K. Petersen authored
      Commit d2bcbeab ("scsi: blkcg: Add app identifier support for
      blkcg") introduced an FC_APPID config option under SCSI. However, the
      added config option is not used anywhere. Simply remove it.
      
      The block layer BLK_CGROUP_FC_APPID config option is what actually
      controls whether the application ID code should be built or not. Make
      this option dependent on NVMe over FC since that is currently the only
      transport which supports the capability.

      exfat: handle wrong stream entry size in exfat_readdir() · 1e5654de
      Namjae Jeon authored
      The compatibility issue between linux exfat and exfat of some camera
      company was reported from Florian. In their exfat, if the number of files
      exceeds any limit, the DataLength in stream entry of the directory is
      no longer updated. So some files created from camera does not show in
      linux exfat. because linux exfat doesn't allow that cpos becomes larger
      than DataLength of stream entry. This patch check DataLength in stream
      entry only if the type is ALLOC_NO_FAT_CHAIN and add the check ensure
      that dentry offset does not exceed max dentries size(256 MB) to avoid
      the circular FAT chain issue.
