      ata: ahci_platform: fix null-ptr-deref in ahci_platform_enable_regulators() · 776c7501

      I got a null-ptr-deref report:

      If devm_regulator_get() in ahci_platform_get_resources() fails,

      commit 962399bb ("ata: libahci_platform: Fix regulator_get_optional()
      misuse") replaces devm_regulator_get_optional() with devm_regulator_get(),
      but PHY regulator omits to delete "hpriv->phy_regulator = NULL;" like AHCI.
      Delete it like AHCI regulator to fix this bug.

       "A bit of a big batch, partly because I didn't send any last week, and
        also just because the BPF fixes happened to land this week.
      
        Summary:
      
         - Fix a regression hit by the IPR SCSI driver, introduced by the
           recent addition of MSI domains on pseries.
      
         - A big series including 8 BPF fixes, some with potential security
           impact and the rest various code generation issues.
      
         - Fix our program check assembler entry path, which was accidentally
           jumping into a gas macro and generating strange stack frames, which
           could confuse find_bug().
      
         - A couple of fixes, and related changes, to fix corner cases in our
           machine check handling.
      
         - Fix our DMA IOMMU ops, which were not always returning the optimal
           DMA mask, leading to at least one device falling back to 32-bit DMA
           when it shouldn't.
      
         - A fix for KUAP handling on 32-bit Book3S.
      
         - Fix crashes seen when kdumping on some pseries systems.

       "There is one build fix for Arm platforms that ended up impacting most
        architectures because of the way the drivers/firmware Kconfig file is
        wired up:
      
        The CONFIG_QCOM_SCM dependency have caused a number of randconfig
        regressions over time, and some still remain in v5.15-rc4. The fix we
        agreed on in the end is to make this symbol selected by any driver
        using it, and then building it even for non-Arm platforms with
        CONFIG_COMPILE_TEST.
      
        To make this work on all architectures, the drivers/firmware/Kconfig
        file needs to be included for all architectures to make the symbol
        itself visible.
      
        In a separate discussion, we found that a sound driver patch that is
        pending for v5.16 needs the same change to include this Kconfig file,
        so the easiest solution seems to have my Kconfig rework included in
        v5.15.
      
        Finally, the branch also includes a small unrelated build fix for
        NOMMU architectures"

      x86/fpu: Restore the masking out of reserved MXCSR bits · d298b035

      Ser bisected the problem to the commit in Fixes.
      
      tglx suggested reverting the rejection of invalid MXCSR values which
      this commit introduced and replacing it with what the old code did -
      simply masking them out to zero.
      
      Further debugging confirmed his suggestion:
      
        fpu->state.fxsave.mxcsr: 0xb7be13b4, mxcsr_feature_mask: 0xffbf
        WARNING: CPU: 0 PID: 1 at arch/x86/kernel/fpu/signal.c:384 __fpu_restore_sig+0x51f/0x540
      
      so restore the original behavior only for 32-bit kernels where you have
      ancient machines with buggy hardware. For 32-bit programs on 64-bit
      kernels, user space which supplies wrong MXCSR values is considered
      malicious so fail the sigframe restoration there.

      Fixes for omaps for v5.15
      
      Few regression fixes for omaps for the v5.15-rc cycle. There is a fix
      for boot time hangs that can happen on some am335x devices that started
      when the pruss devicetree nodes were added. The other fixes are less
      critical:
      
      - Fix compiler warning for sysc_init_soc() that got recently introduced
      
      - Fix external abort for am335x pruss as otherwise some am335x will hang

      PCI: ACPI: Check parent pointer in acpi_pci_find_companion() · 3fb937f4
      Rafael J. Wysocki authored
      If acpi_pci_find_companion() is called for a device whose parent
      pointer is NULL, it will crash when attempting to get the ACPI
      companion of the parent due to a NULL pointer dereference in
      the ACPI_COMPANION() macro.
      
      This was not a problem before commit 375553a9 ("PCI: Setup ACPI
      fwnode early and at the same time with OF") that made pci_setup_device()
      call pci_set_acpi_fwnode() and so it allowed devices with NULL parent
      pointers to be passed to acpi_pci_find_companion() which is the case
      in pci_iov_add_virtfn(), for instance.
      
      Fix this issue by making acpi_pci_find_companion() check the device's
      parent pointer upfront and bail out if it is NULL.
      
      While pci_iov_add_virtfn() can be changed to set the device's parent
      pointer before calling pci_setup_device() for it, checking pointers
      against NULL before dereferencing them is prudent anyway and looking
      for ACPI companions of virtual functions isn't really useful.

      Namjae Jeon authored
      Marios reported kernel oops from fuse driver when ksmbd call
      mark_inode_dirty(). This patch directly update ->i_ctime after removing
      mark_inode_ditry() and notify_change will put inode to dirty list.
