      parisc: Fix argument pointer in real64_call_asm() · 6e3220ba
      Helge Deller authored
      Fix the argument pointer (ap) to point to real-mode memory
      instead of virtual memory.
      
      It's interesting that this issue hasn't shown up earlier, as this could
      have happened with any 64-bit PDC ROM code.
      
      I just noticed it because I suddenly faced a HPMC while trying to execute
      the 64-bit STI ROM code of an Visualize-FXe graphics card for the STI
      text console.

      parisc: Cleanup mmap implementation regarding color alignment · 567b3515
      John David Anglin authored
      This change simplifies the randomization of file mapping regions. It
      reworks the code to remove duplication. The flow is now similar to
      that for mips. Finally, we consistently use the do_color_align variable
      to determine when color alignment is needed.
      
      Tested on rp3440.

      parisc: Ensure page alignment in flush functions · d755bd2c
      Helge Deller authored
      Matthew Wilcox noticed, that if ARCH_HAS_FLUSH_ON_KUNMAP is defined
      (which is the case for PA-RISC), __kunmap_local() calls
      kunmap_flush_on_unmap(), which may call the parisc flush functions with
      a non-page-aligned address and thus the page might not be fully flushed.
      
      This patch ensures that flush_kernel_dcache_page_asm() and
      flush_kernel_dcache_page_asm() will always operate on page-aligned
      addresses.

      parisc: Replace regular spinlock with spin_trylock on panic path · 829632da
      Guilherme G. Piccoli authored
      The panic notifiers' callbacks execute in an atomic context, with
      interrupts/preemption disabled, and all CPUs not running the panic
      function are off, so it's very dangerous to wait on a regular
      spinlock, there's a risk of deadlock.
      
      Refactor the panic notifier of parisc/power driver to make use
      of spin_trylock - for that, we've added a second version of the
      soft-power function. Also, some comments were reorganized and
      trailing white spaces, useless header inclusion and blank lines
      were removed.

      sysctl: remove register_sysctl_paths() · 0199849a
      Luis Chamberlain authored
      The deprecation for register_sysctl_paths() is over. We can rejoice as
      we nuke register_sysctl_paths(). The routine register_sysctl_table()
      was the only user left of register_sysctl_paths(), so we can now just
      open code and move the implementation over to what used to be
      to __register_sysctl_paths().
      
      The old dynamic struct ctl_table_set *set is now the point to
      sysctl_table_root.default_set.
      
      The old dynamic const struct ctl_path *path was being used in the
      routine register_sysctl_paths() with a static:
      
      static const struct ctl_path null_path[] = { {} };
      
      Since this is a null path we can now just simplfy the old routine
      and remove its use as its always empty.
      
      This saves us a total of 230 bytes.

      kernel: pid_namespace: simplify sysctls with register_sysctl() · 9e7c73c0
      Luis Chamberlain authored
      register_sysctl_paths() is only required if your child (directories)
      have entries and pid_namespace does not. So use register_sysctl_init()
      instead where we don't care about the return value and use
      register_sysctl() where we do.

      Pull pin control updates from Linus Walleij:
       "Mostly drivers! Nothing special: some new Qualcomm chips as usual, and
        the new NXP S32 and nVidia BlueField-3.
      
        Core changes:
      
         - Make a lot of pin controllers with GPIO and irqchips immutable,
           i.e. not living structs, but const structs. This is driving a
           changed initiated by the irqchip maintainers.
      
        New drivers:
      
         - New driver for the NXP S32 SoC pin controller
      
         - As part of a thorough cleanup and restructuring of the
           Ralink/Mediatek drivers, the Ralink MIPS pin control drivers were
           folded into the Mediatek directory and the family is renamed
           "mtmips". The Ralink chips live on as Mediatek MIPS family where
           new variants can be added. As part of this work also the device
           tree bindings were reworked.
      
         - New subdriver for the Qualcomm SM7150 SoC.
      
         - New subdriver for the Qualcomm IPQ9574 SoC.
      
         - New driver for the nVidia BlueField-3 SoC.
      
         - Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.
      
         - Support for the Qualcomm PMI632 mixed signal circuit GPIO.
      
        Improvements:
      
         - Add some missing pins and generic cleanups on the Renesas r8a779g0
           and r8a779g0 pin controllers. Generic Renesas extension for power
           source selection on several SoCs.
      
         - Misc cleanups for the Atmel AT91 and AT91-PIO4 pin controllers
      
         - Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi driver.
      
         - Several device tree binding cleanups as the binding YAML syntax is
           solidifying"

         - Make afs_getattr() always return the server's dir file size, not
           the locally edited one, so that pagecache eviction doesn't cause
           the dir file size to change unexpectedly.

      afs_read_dir fetches an amount of data that's based on what the inode
      size is thought to be.  If the file on the server is larger than what
      was fetched, the code rechecks i_size and retries.  If the local i_size
      was not properly updated, this can lead to an endless loop of fetching
      i_size from the server and noticing each time that the size is larger on
      the server.
      
      If it is known that the remote size is larger than i_size, bump up the
      fetch size to that size.

      afs: Fix getattr to report server i_size on dirs, not local size · 45f66fa0
      David Howells authored
      Fix afs_getattr() to report the server's idea of the file size of a
      directory rather than the local size.  The local size may differ as we edit
      the local copy to avoid having to redownload it and we may end up with a
      differently structured blob of a different size.
      
      However, if the directory is discarded from the pagecache we then download
      it again and the user may see the directory file size apparently change.

      afs: Fix updating of i_size with dv jump from server · d7f74e9a
      Marc Dionne authored
      If the data version returned from the server is larger than expected,
      the local data is invalidated, but we may still want to note the remote
      file size.
      
      Since we're setting change_size, we have to also set data_changed
      for the i_size to get updated.
