ME FW contributes a vital role in HDCP2.2 authentication.
HDCP2.2 driver needs to communicate to ME FW for each step of the
HDCP2.2 authentication.

ME FW prepare and HDCP2.2 authentication  parameters and encrypt them
as per spec. With such parameter Driver prepares HDCP2.2 auth messages
and communicate with HDCP2.2 sink.

Similarly HDCP2.2 sink's response is shared with ME FW for decrypt and
verification.

Once All the steps of HDCP2.2 authentications are complete on driver's
request ME FW will configure the port as authenticated and supply the
HDCP keys to the Gen HW for encryption.

Only after this stage HDCP2.2 driver can start the HDCP2.2 encryption
for a port.

ME FW is interfaced to kernel through MEI Bus Driver. To obtain the
HDCP2.2 services from the ME FW through MEI Bus driver MEI Client
Driver is developed.

In the original code before 181bf1e8 the loop was continuing until
it finds the first matching superios[i].io and p->base.
But after 181bf1e8 the logic changed and the loop now returns the
pointer to the first mismatched array element which is then used in
get_superio_dma() and get_superio_irq() and thus returning the wrong
value.
Fix the condition so that it now returns the correct pointer.

set_pmd_at() calls native_set_pmd() unconditionally on x86. This was
fine as long as only huge page entries were written via set_pmd_at(),
as Xen pv guests don't support those.

Commit 2c91bd4a ("mm: speed up mremap by 20x on large regions")
introduced a usage of set_pmd_at() possible on pv guests, leading to
failures like:

BUG: unable to handle kernel paging request at ffff888023e26778
#PF error: [PROT] [WRITE]
RIP: e030:move_page_tables+0x7c1/0xae0
move_vma.isra.3+0xd1/0x2d0
__se_sys_mremap+0x3c6/0x5b0
 do_syscall_64+0x49/0x100
entry_SYSCALL_64_after_hwframe+0x44/0xa9

Make set_pmd_at() paravirt aware by just letting it use set_pmd().

Pull MIPS fixes from Paul Burton:
 "A batch of MIPS fixes for 5.0, nothing too scary.

   - A workaround for a Loongson 3 CPU bug is the biggest change, but
     still fairly straightforward. It adds extra memory barriers (sync
     instructions) around atomics to avoid a CPU bug that can break
     atomicity.

   - Loongson64 also sees a fix for powering off some systems which
     would incorrectly reboot rather than waiting for the power down
     sequence to complete.

   - We have DT fixes for the Ingenic JZ4740 SoC & the JZ4780-based Ci20
     board, and a DT warning fix for the Nexsys4/MIPSfpga board.

   - The Cavium Octeon platform sees a further fix to the behaviour of
     the pcie_disable command line argument that was introduced in v3.3.

   - The VDSO, introduced in v4.4, sees build fixes for configurations
     of GCC that were built using the --with-fp-32= flag to specify a
     default 32-bit floating point ABI.

   - get_frame_info() sees a fix for configurations with
     CONFIG_KALLSYMS=n, for which it previously always returned an
     error.

   - If the MIPS Coherence Manager (CM) reports an error then we'll now
     clear that error correctly so that the GCR_ERROR_CAUSE register
     will be updated with information about any future errors"

Pull ARM SoC fixes from Arnd Bergmann:
 "This is a bit larger than normal, as we had not managed to send out a
  pull request before traveling for a week without my signing key.

  There are multiple code fixes for older bugs, all of which should get
  backported into stable kernels:

   - tango: one fix for multiplatform configurations broken on other
     platforms when tango is enabled

   - arm_scmi: device unregistration fix

   - iop32x: fix kernel oops from extraneous __init annotation

   - pxa: remove a double kfree

   - fsl qbman: close an interrupt clearing race

  The rest is the usual collection of smaller fixes for device tree
  files, on the renesas, allwinner, meson, omap, davinci, qualcomm and
  imx platforms.

  Some of these are for compile-time warnings, most are for board
  specific functionality that fails to work because of incorrect
  settings"
