      parisc: fix out-of-register compiler error in ldcw inline assembler function · 45db0738
      John David Anglin authored
      The __ldcw macro has a problem when its argument needs to be reloaded from
      memory. The output memory operand and the input register operand both need to
      be reloaded using a register in class R1_REGS when generating 64-bit code.
      This fails because there's only a single register in the class. Instead, use a
      memory clobber. This also makes the __ldcw macro a compiler memory barrier.

      ALSA: hda_intel: apply the Seperate stream_tag for Skylake · d6795827
      Libin Yang authored
      The total stream number of Skylake's input and output stream
      exceeds 15, which will cause some streams do not work because
      of the overflow on SDxCTL.STRM field if using the legacy
      stream tag allocation method.
      
      This patch uses the new stream tag allocation method by add
      the flag AZX_DCAPS_SEPARATE_STREAM_TAG for Skylake platform.

      ALSA: hda_controller: Separate stream_tag for input and output streams. · 93e3423e
      Rafal Redzimski authored
      Implemented separate stream_tag assignment for input and output streams.
      According to hda specification stream tag must be unique throughout the
      input streams group, however an output stream might use a stream tag
      which is already in use by an input stream. This change is necessary
      to support HW which provides a total of more than 15 stream DMA engines
      which with legacy implementation causes an overflow on SDxCTL.STRM
      field (and the whole SDxCTL register) and as a result usage of
      Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.

      audit: restore AUDIT_LOGINUID unset ABI · 041d7b98
      Richard Guy Briggs authored
      A regression was caused by commit 780a7654:
      	 audit: Make testing for a valid loginuid explicit.
      (which in turn attempted to fix a regression caused by e1760bd5)
      
      When audit_krule_to_data() fills in the rules to get a listing, there was a
      missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID.
      
      This broke userspace by not returning the same information that was sent and
      expected.
      
      The rule:
      	auditctl -a exit,never -F auid=-1
      gives:
      	auditctl -l
      		LIST_RULES: exit,never f24=0 syscall=all
      when it should give:
      		LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all
      
      Tag it so that it is reported the same way it was set.  Create a new
      private flags audit_krule field (pflags) to store it that won't interact with
      the public one from the API.

      arm64: mm: Add pgd_page to support RCU fast_gup · 5d96e0cb

      This patch adds pgd_page definition in order to keep supporting
      HAVE_GENERIC_RCU_GUP configuration. In addition, it changes pud_page
      expression to align with pmd_page for readability.

      arm64: kernel: fix __cpu_suspend mm switch on warm-boot · f43c2718
      Lorenzo Pieralisi authored
      On arm64 the TTBR0_EL1 register is set to either the reserved TTBR0
      page tables on boot or to the active_mm mappings belonging to user space
      processes, it must never be set to swapper_pg_dir page tables mappings.
      
      When a CPU is booted its active_mm is set to init_mm even though its
      TTBR0_EL1 points at the reserved TTBR0 page mappings. This implies
      that when __cpu_suspend is triggered the active_mm can point at
      init_mm even if the current TTBR0_EL1 register contains the reserved
      TTBR0_EL1 mappings.
      
      Therefore, the mm save and restore executed in __cpu_suspend might
      turn out to be erroneous in that, if the current->active_mm corresponds
      to init_mm, on resume from low power it ends up restoring in the
      TTBR0_EL1 the init_mm mappings that are global and can cause speculation
      of TLB entries which end up being propagated to user space.
      
      This patch fixes the issue by checking the active_mm pointer before
      restoring the TTBR0 mappings. If the current active_mm == &init_mm,
      the code sets the TTBR0_EL1 to the reserved TTBR0 mapping instead of
      switching back to the active_mm, which is the expected behaviour
      corresponding to the TTBR0_EL1 settings when __cpu_suspend was entered.
