Pull RISC-V fix from Palmer Dabbelt:

 - A fix to relocate the DTB early in boot, in cases where the
   bootloader doesn't put the DTB in a region that will end up
   mapped by the kernel.

   This manifests as a crash early in boot on a handful of
   configurations.

Pull kvm fixes from Paolo Bonzini:
 "ARM:

   - Take care of faults occuring between the PARange and IPA range by
     injecting an exception

   - Fix S2 faults taken from a host EL0 in protected mode

   - Work around Oops caused by a PMU access from a 32bit guest when PMU
     has been created. This is a temporary bodge until we fix it for
     good.

   - Fix potential races when walking host page table

   - Fix shadow page table leak when KVM runs nested

   - Work around bug in userspace when KVM synthesizes leaf 0x80000021
     on older (pre-EPYC) or Intel processors

Pull clk fixes from Stephen Boyd:
 "A semi-large pile of clk driver fixes this time around.

  Nothing is touching the core so these fixes are fairly well contained
  to specific devices that use these clk drivers.

   - Some Allwinner SoC fixes to gracefully handle errors and mark an
     RTC clk as critical so that the RTC keeps ticking.

   - Fix AXI bus clks and RTC clk design for Microchip PolarFire SoC
     driver introduced this cycle. This has some devicetree bits acked
     by riscv maintainers. We're fixing it now so that the prior
     bindings aren't released in a major kernel version.

   - Remove a reset on Microchip PolarFire SoCs that broke when enabling
     CONFIG_PM.

   - Set a min/max for the Qualcomm graphics clk. This got broken by the
     clk rate range patches introduced this cycle"

Fixes for (relatively) old bugs, to be merged in both the -rc and next
development trees:

* Fix potential races when walking host page table

* Fix bad user ABI for KVM_EXIT_SYSTEM_EVENT

* Fix shadow page table leak when KVM runs nested

When KVM_EXIT_SYSTEM_EVENT was introduced, it included a flags
member that at the time was unused.  Unfortunately this extensibility
mechanism has several issues:

- x86 is not writing the member, so it would not be possible to use it
  on x86 except for new events

- the member is not aligned to 64 bits, so the definition of the
  uAPI struct is incorrect for 32- on 64-bit userspace.  This is a
  problem for RISC-V, which supports CONFIG_KVM_COMPAT, but fortunately
  usage of flags was only introduced in 5.18.

Since padding has to be introduced, place a new field in there
that tells if the flags field is valid.  To allow further extensibility,
in fact, change flags to an array of 16 values, and store how many
of the values are valid.  The availability of the new ndata field
is tied to a system capability; all architectures are changed to
fill in the field.

To avoid breaking compilation of userspace that was using the flags
field, provide a userspace-only union to overlap flags with data[0].
The new field is placed at the same offset for both 32- and 64-bit
userspace.

In case the DTB provided by the bootloader/BootROM is before the kernel
image or outside /memory, we won't be able to access it through the
linear mapping, and get a segfault on setup_arch(). Currently OpenSBI
relocates DTB but that's not always the case (e.g. if FW_JUMP_FDT_ADDR
is not specified), and it's also not the most portable approach since
the default FW_JUMP_FDT_ADDR of the generic platform relocates the DTB
at a specific offset that may not be available. To avoid this situation
copy DTB so that it's visible through the linear mapping.
