      iommu/arm-smmu-qcom: hide last LPASS SMMU context bank from linux · 3a8990b8
      Marc Gonzalez authored
      On qcom msm8998, writing to the last context bank of lpass_q6_smmu
      (base address 0x05100000) produces a system freeze & reboot.
      
      The hardware/hypervisor reports 13 context banks for the LPASS SMMU
      on msm8998, but only the first 12 are accessible...
      Override the number of context banks
      
      [    2.546101] arm-smmu 5100000.iommu: probing hardware configuration...
      [    2.552439] arm-smmu 5100000.iommu: SMMUv2 with:
      [    2.558945] arm-smmu 5100000.iommu: 	stage 1 translation
      [    2.563627] arm-smmu 5100000.iommu: 	address translation ops
      [    2.568923] arm-smmu 5100000.iommu: 	non-coherent table walk
      [    2.574566] arm-smmu 5100000.iommu: 	(IDR0.CTTW overridden by FW configuration)
      [    2.580220] arm-smmu 5100000.iommu: 	stream matching with 12 register groups
      [    2.587263] arm-smmu 5100000.iommu: 	13 context banks (0 stage-2 only)
      [    2.614447] arm-smmu 5100000.iommu: 	Supported page sizes: 0x63315000
      [    2.621358] arm-smmu 5100000.iommu: 	Stage-1: 36-bit VA -> 36-bit IPA
      [    2.627772] arm-smmu 5100000.iommu: 	preserved 0 boot mappings
      
      Specifically, the crashes occur here:
      
      	qsmmu->bypass_cbndx = smmu->num_context_banks - 1;
      	arm_smmu_cb_write(smmu, qsmmu->bypass_cbndx, ARM_SMMU_CB_SCTLR, 0);
      
      and here:
      
      	arm_smmu_write_context_bank(smmu, i);
      	arm_smmu_cb_write(smmu, i, ARM_SMMU_CB_FSR, ARM_SMMU_CB_FSR_FAULT);
      
      It is likely that FW reserves the last context bank for its own use,
      thus a simple work-around is: DON'T USE IT in Linux.
      
      If we decrease the number of context banks, last one will be "hidden".

      Pull x86 fixes from Thomas Gleixner:
      
       - Fix 32-bit PTI for real.
      
         pti_clone_entry_text() is called twice, once before initcalls so that
         initcalls can use the user-mode helper and then again after text is
         set read only. Setting read only on 32-bit might break up the PMD
         mapping, which makes the second invocation of pti_clone_entry_text()
         find the mappings out of sync and failing.
      
         Allow the second call to split the existing PMDs in the user mapping
         and synchronize with the kernel mapping.
      
       - Don't make acpi_mp_wake_mailbox read-only after init as the mail box
         must be writable in the case that CPU hotplug operations happen after
         boot. Otherwise the attempt to start a CPU crashes with a write to
         read only memory.
      
       - Add a missing sanity check in mtrr_save_state() to ensure that the
         fixed MTRR MSRs are supported.
      
         Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but
         the WARN_ON() can bring systems down when panic on warn is set.

      Pull time keeping fixes from Thomas Gleixner:
      
       - Fix a couple of issues in the NTP code where user supplied values are
         neither sanity checked nor clamped to the operating range. This
         results in integer overflows and eventualy NTP getting out of sync.
      
         According to the history the sanity checks had been removed in favor
         of clamping the values, but the clamping never worked correctly under
         all circumstances. The NTP people asked to not bring the sanity
         checks back as it might break existing applications.
      
         Make the clamping work correctly and add it where it's missing
      
       - If adjtimex() sets the clock it has to trigger the hrtimer subsystem
         so it can adjust and if the clock was set into the future expire
         timers if needed. The caller should provide a bitmask to tell
         hrtimers which clocks have been adjusted.
      
         adjtimex() uses not the proper constant and uses CLOCK_REALTIME
         instead, which is 0. So hrtimers adjusts only the clocks, but does
         not check for expired timers, which might make them expire really
         late. Use the proper bitmask constant instead.
