       "Fixes:
      
         - When we added basic vDSO support in kernel 5.18 we introduced a bug
           which prevented a mmap() of graphic card memory. This is because we
           used the DMB (data memory break trap bit) page flag as special-bit,
           but missed to clear that bit when loading the TLB.
      
         - Graphics card memory size was not correctly aligned
      
         - Spelling fixes (from Colin Ian King)
      
        Enhancements:
      
         - PDC console (which uses firmware calls) now rewritten as early

      drm/amd/display: Fix build breakage with CONFIG_DEBUG_FS=n · 2130b87b
      Nathan Chancellor authored
      After commit 8799c0be ("drm/amd/display: Fix vblank refcount in vrr
      transition"), a build with CONFIG_DEBUG_FS=n is broken due to a
      misplaced brace, along the lines of:

      parisc: Fix userspace graphics card breakage due to pgtable special bit · 70be49f2
      Helge Deller authored
      Commit df24e178 ("parisc: Add vDSO support") introduced the vDSO
      support, for which a _PAGE_SPECIAL page table flag was needed.  Since we
      wanted to keep every page table entry in 32-bits, this patch re-used the
      existing - but yet unused - _PAGE_DMB flag (which triggers a hardware break
      if a page is accessed) to store the special bit.
      
      But when graphics card memory is mmapped into userspace, the kernel uses
      vm_iomap_memory() which sets the the special flag. So, with the DMB bit
      set, every access to the graphics memory now triggered a hardware
      exception and segfaulted the userspace program.
      
      Fix this breakage by dropping the DMB bit when writing the page
      protection bits to the CPU TLB.
      
      In addition this patch adds a small optimization: if huge pages aren't
      configured (which is at least the case for 32-bit kernels), then the
      special bit is stored in the hpage (HUGE PAGE) bit instead. That way we
      can skip to reset the DMB bit.

      rtc: cmos: Fix event handler registration ordering issue · 4919d3eb
      Rafael J. Wysocki authored
      Because acpi_install_fixed_event_handler() enables the event
      automatically on success, it is incorrect to call it before the
      handler routine passed to it is ready to handle events.
      
      Unfortunately, the rtc-cmos driver does exactly the incorrect thing
      by calling cmos_wake_setup(), which passes rtc_handler() to
      acpi_install_fixed_event_handler(), before cmos_do_probe(), because
      rtc_handler() uses dev_get_drvdata() to get to the cmos object
      pointer and the driver data pointer is only populated in
      cmos_do_probe().
      
      This leads to a NULL pointer dereference in rtc_handler() on boot
      if the RTC fixed event happens to be active at the init time.
      
      To address this issue, change the initialization ordering of the
      driver so that cmos_wake_setup() is always called after a successful
      cmos_do_probe() call.
      
      While at it, change cmos_pnp_probe() to call cmos_do_probe() after
      the initial if () statement used for computing the IRQ argument to
      be passed to cmos_do_probe() which is cleaner than calling it in
      each branch of that if () (local variable "irq" can be of type int,
      because it is passed to that function as an argument of type int).
      
      Note that commit 6492fed7 ("rtc: rtc-cmos: Do not check
      ACPI_FADT_LOW_POWER_S0") caused this issue to affect a larger number
      of systems, because previously it only affected systems with
      ACPI_FADT_LOW_POWER_S0 set, but it is present regardless of that
      commit.
      
      Fixes: 6492fed7 ("rtc: rtc-cmos: Do not check ACPI_FADT_LOW_POWER_S0")

      RISC-V: Make port I/O string accessors actually work · 9cc205e3
      Maciej W. Rozycki authored
      Fix port I/O string accessors such as `insb', `outsb', etc. which use
      the physical PCI port I/O address rather than the corresponding memory
      mapping to get at the requested location, which in turn breaks at least
      accesses made by our parport driver to a PCIe parallel port such as:
      
      PCI parallel port detected: 1415:c118, I/O at 0x1000(0x1008), IRQ 20
      parport0: PC-style at 0x1000 (0x1008), irq 20, using FIFO [PCSPP,TRISTATE,COMPAT,EPP,ECP]
      
      causing a memory access fault:
      
      Unable to handle kernel access to user memory without uaccess routines at virtual address 0000000000001008

      For simplicity address the problem by adding PCI_IOBASE to the physical
      address requested in the respective wrapper macros only, observing that
      the raw accessors such as `__insb', `__outsb', etc. are not supposed to
      be used other than by said macros.  Remove the cast to `long' that is no
      longer needed on `addr' now that it is used as an offset from PCI_IOBASE
      and add parentheses around `addr' needed for predictable evaluation in
      macro expansion.  No need to make said adjustments in separate changes
      given that current code is gravely broken and does not ever work.

      RISC-V: Make mmap() with PROT_WRITE imply PROT_READ · 8aeb7b17
      Palmer Dabbelt authored
      Commit 2139619b ("riscv: mmap with PROT_WRITE but no PROT_READ is
      invalid") made mmap() reject mappings with only PROT_WRITE set in an
      attempt to fix an observed inconsistency in behavior when attempting
      to read from a PROT_WRITE-only mapping. The root cause of this behavior
      was actually that while RISC-V's protection_map maps VM_WRITE to
      readable PTE permissions (since write-only PTEs are considered reserved
      by the privileged spec), the page fault handler considered loads from
      VM_WRITE-only VMAs illegal accesses. Fix the underlying cause by
      handling faults in VM_WRITE-only VMAs (patch 1) and then re-enable
      use of mmap(PROT_WRITE) (patch 2), making RISC-V's behavior consistent
      with all other architectures that don't support write-only PTEs.

      riscv: enable software resend of irqs · c45fc916
      Conor Dooley authored
      The PLIC specification does not describe the interrupt pendings bits as
      read-write, only that they "can be read". To allow for retriggering of
      interrupts (and the use of the irq debugfs interface) enable
      HARDIRQS_SW_RESEND for RISC-V.

      This is because the mm->context.vdso_info is NULL in vfork case. From
      another side, mm->context.vdso_info either points to vdso info
      for RV64 or vdso info for compat, there's no need to bloat riscv's
      mm_context_t, we can handle the difference when setup the additional
      page for vdso.
