      Pull powerpc fixes from Michael Ellerman:
       "A bunch of fixes, mostly for existing code and going to stable.
      
        Our memory hot-unplug path wasn't flushing the cache before removing
        memory. That is a problem now that we are doing memory hotplug on bare
        metal.
      
        Three fixes for the NPU code that supports devices connected via
        NVLink (ie. GPUs). The main one tweaks the TLB flush algorithm to
        avoid soft lockups for large flushes.
      
        A fix for our memory error handling where we would loop infinitely,
        returning back to the bad access and hard lockup the CPU.
      
        Fixes for the OPAL RTC driver, which wasn't handling some error cases
        correctly.
      
        A fix for a hardlockup in the powernv cpufreq driver.
      
        And finally two fixes to our smp_send_stop(), required due to a recent
        change to use it on shutdown.
      
        Thanks to: Alistair Popple, Balbir Singh, Laurentiu Tudor, Mahesh
        Salgaonkar, Mark Hairgrove, Nicholas Piggin, Rashmica Gupta, Shilpasri

         - a couple of patches all intended to finally turn on USB support on

           finalized until very late before the merge window and the DT
           portion is the last bit now.
      
         - a defconfig update for gemini that had repeatedly missed the cut
           but that is required to actually boot any real machines with the
           default build.
      
        The rest are the usual small changes:

      kvm: apic: Flush TLB after APIC mode/address change if VPIDs are in use · a468f2db
      Junaid Shahid authored
      Currently, KVM flushes the TLB after a change to the APIC access page
      address or the APIC mode when EPT mode is enabled. However, even in
      shadow paging mode, a TLB flush is needed if VPIDs are being used, as
      specified in the Intel SDM Section 29.4.5.
      
      So replace vmx_flush_tlb_ept_only() with vmx_flush_tlb(), which will
      flush if either EPT or VPIDs are in use.

      arm64: avoid instrumenting atomic_ll_sc.o · 3789c122
      Mark Rutland authored
      Our out-of-line atomics are built with a special calling convention,
      preventing pointless stack spilling, and allowing us to patch call sites
      with ARMv8.1 atomic instructions.
      
      Instrumentation inserted by the compiler may result in calls to
      functions not following this special calling convention, resulting in
      registers being unexpectedly clobbered, and various problems resulting
      from this.
      
      For example, if a kernel is built with KCOV and ARM64_LSE_ATOMICS, the
      compiler inserts calls to __sanitizer_cov_trace_pc in the prologues of
      the atomic functions. This has been observed to result in spurious
      cmpxchg failures, leading to a hang early on in the boot process.
      
      This patch avoids such issues by preventing instrumentation of our
      out-of-line atomics.

      powerpc: Fix deadlock with multiple calls to smp_send_stop · 6029755e
      Nicholas Piggin authored
      smp_send_stop can lock up the IPI path for any subsequent calls,
      because the receiving CPUs spin in their handler function. This
      started becoming a problem with the addition of an smp_send_stop
      call in the reboot path, because panics can reboot after doing
      their own smp_send_stop.
      
      The NMI IPI variant was fixed with ac61c115 ("powerpc: Fix
      smp_send_stop NMI IPI handling"), which leaves the smp_call_function
      variant.
      
      This is fixed by having smp_send_stop only ever do the
      smp_call_function once. This is a bit less robust than the NMI IPI
      fix, because any other call to smp_call_function after smp_send_stop
      could deadlock, but that has always been the case, and it was not
      been a problem before.

      cpufreq: powernv: Fix hardlockup due to synchronous smp_call in timer interrupt · c0f7f5b6
      Shilpasri G Bhat authored
      gpstate_timer_handler() uses synchronous smp_call to set the pstate
      on the requested core. This causes the below hard lockup:
      
        smp_call_function_single+0x110/0x180 (unreliable)
        smp_call_function_any+0x180/0x250

        SyS_mprotect+0x1b4/0x350
        system_call+0x58/0x6c
      
      One way to avoid this is removing the smp-call. We can ensure that the
      timer always runs on one of the policy-cpus. If the timer gets
      migrated to a cpu outside the policy then re-queue it back on the
      policy->cpus. This way we can get rid of the smp-call which was being
      used to set the pstate on the policy->cpus.

      mtd: rawnand: marvell: fix the chip-select DT parsing logic · f6997bec
      Miquel Raynal authored
      The block responsible of parsing the DT for the number of chip-select
      lines uses an 'if/else if/else if' block. The content of the second and
      third 'else if' conditions are:
              1/ the actual condition to enter the sub-block and
              2/ the operation to do in this sub-block.
      
              [...]
              else if (condition1_to_enter && action1() == failed)
                      raise_error();
              else if (condition2_to_enter && action2() == failed)
                      raise_error();
              [...]
      
      In case of failure, the sub-block is entered and an error raised.
      Otherwise, in case of success, the code would continue erroneously in
      the next 'else if' statement because it did not failed (and did not
      enter the first 'else if' sub-block).
      
      The first 'else if' refers to legacy bindings while the second 'else if'
      refers to new bindings. The second 'else if', which is entered
      erroneously, checks for the 'reg' property, which, for old bindings,
      does not mean anything because it would not be the number of CS
      available, but the regular register map of almost any DT node. This
      being said, the content of the 'reg' property being the register map
      offset and length, it has '2' values, so the number of CS in this
      situation is assumed to be '2'.
      
      When running nand_scan_ident() with 2 CS, the core will check for an
      array of chips. It will first issue a RESET and then a READ_ID. Of
      course this will trigger two timeouts because there is no chip in front
      of the second CS:
      
      [    1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080)
      [    1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280)
      
      Indeed, this is harmless and the core will then assume there is only one
      valid CS.
      
      Fix the logic in the whole block by entering each sub-block just on the
      'is legacy' condition, doing the action inside the sub-block. This way,
      when the action succeeds, the whole block is left.
      
      Furthermore, for both the old bindings and the new bindings the same
      logic was applied to retrieve the number of CS lines:
      using of_get_property() to get a size in bytes, converted in the actual
      number of lines by dividing it per sizeof(u32) (4 bytes).
      
      This is fine for the 'reg' property which is a list of the CS IDs but
      not for the 'num-cs' property which is directly the value of the number
      of CS.
      
      Anyway, no existing DT uses another value than 'num-cs = <1>' and no
      other value has ever been supported by the old driver (pxa3xx_nand.c).
      Remove this condition and apply a number of 1 CS anyway, as already
      described in the bindings.
      
      Finally, the 'reg' property of a 'nand' node (with the new bindings)
      gives the IDs of each CS line in use. marvell_nand.c driver first look
      at the number of CS lines that are present in this property.
      
      Better use of_property_count_elems_of_size() than dividing by 4 the size
      of the number of bytes returned by of_get_property().

      It's possible for userspace to control n. Sanitize n when using it as an
      array index.
      
      Note that while it appears that n must be bound to the interval [0,3]
      due to the way it is extracted from addr, we cannot guarantee that
      compiler transformations (and/or future refactoring) will ensure this is
      the case, and given this is a slow path it's better to always perform
      the masking.

      libceph: validate con->state at the top of try_write() · 9c55ad1c
      Ilya Dryomov authored
      ceph_con_workfn() validates con->state before calling try_read() and
      then try_write().  However, try_read() temporarily releases con->mutex,
      notably in process_message() and ceph_con_in_msg_alloc(), opening the
      window for ceph_con_close() to sneak in, close the connection and
      release con->sock.  When try_write() is called on the assumption that
      con->state is still valid (i.e. not STANDBY or CLOSED), a NULL sock
      gets passed to the networking stack:
      
        BUG: unable to handle kernel NULL pointer dereference at 0000000000000020
        IP: selinux_socket_sendmsg+0x5/0x20
      
      Make sure con->state is valid at the top of try_write() and add an
      explicit BUG_ON for this, similar to try_read().

        graphics on the D-Link DIR-685. HIGHMEM support comes in
        as part of this.
      - Enable networking and the new Cortina Gemini ethernet
        driver.
      - Enable MDIO over GPIO and the Realtek PHY devices used on
        several of these systems.
      - Enable I2C over GPIO and SPI over GPIO which is used on
        several of these devices.
      - Enable the Thermal framework, GPIO fan control and LM75 sensor
        adding cooling on the D-Link DNS-313 with no userspace
        involved even if only the kernel is working, rock solid
        thermal for this platform.
      - Enable JEDEC flash probing to support the Eon flash chip in
        D-Link DNS-313.
      - Enable LED disk triggers for the NAS type devices.

      HISI LPC: Add Kconfig MFD_CORE dependency · 4b313ca7
      John Garry authored
      For ACPI support of the HiSilicon LPC driver we depend
      on MFD_CORE config.
      
      Currently the HiSi LPC Kconfig entry does not define this
      dependency, so add it.
      
      The reason for depending on MFD_CORE in the driver is
      that we model the LPC host as an MFD, in that a platform
      device will be created for each device on the bus.
      
      We do this as we need to modify the resources of these
      derived platform devices, something which we should not
      do to the original devices created in the ACPI scan.
      Details in e0aa1563 ("HISI LPC: Add ACPI support").
