Pull clk framework updates from Stephen Boyd:
 "We have a couple new features and changes in the core clk framework
  this time around because we've finally gotten around to fixing some
  long standing issues. There's still work to do though, so this pull
  request is largely laying down the foundation for all the driver
  changes to come in the next merge window.

  The first problem we're alleviating is how parents of clks are
  specified. With the new method, we should see lots of drivers migrate
  away from the current design of string comparisons on the entire clk
  tree to a more direct method where they can use clk_hw pointers or
  more localized names specified in DT or via clkdev. This should reduce
  our reliance on string comparisons for all the topology description
  logic that we've been using for years and hopefully speed some things
  up while avoiding problems we have with generating clk names.

  Beyond that we also got rid of the CLK_IS_BASIC flag because it wasn't
  really helping anyone and we introduced big-endian versions of the
  basic clk types so that we can get rid of clk_{readl,writel}(). Both
  of these are things that driver developers have tried to use over the
  years that I typically bat away during code reviews because they're
  not useful. It's great to see these two things go away so maintainers
  can save time not worrying about these things.

  On the driver side we got the usual collection of new SoC support and
  non-critical fixes and updates to existing code. The big topics that
  stand out are the new driver support for Mediatek MT8183 and MT8516
  SoCs, Amlogic Meson8b and G12a SoCs, and the SiFive FU540 SoC. The
  other patches in the driver pile are mostly fixes for things that are
  being used for the first time or additions for clks that couldn't be
  tested before because there wasn't a consumer driver that exercised
  them. Details are below and also in the sub-maintainer tags.

  Core:
   - Remove clk_readl() and introduce BE versions of basic clk types
   - Rewrite how clk parents can be specified to allow DT/clkdev lookups
   - Removal of the CLK_IS_BASIC clk flag
   - Framework documentation updates and fixes

Pull RTC updates from Alexandre Belloni:
 "A huge series from me this cycle. I went through many drivers to set
  the date and time range supported by the RTC which helps solving HW
  limitation when the time comes (as early as next year for some). This
  time, I focused on drivers using .set_mms and .set_mmss64, allowing me
  to remove those callbacks. About a third of the patches got reviews, I
  actually own the RTCs and I tested another third and the remaining one
  are unlikely to cause any issues.

  Other than that, a single new driver and the usual fixes here and there.

  Summary:

  Subsystem:

   - set_mmss and set_mmss64 rtc_ops removal

   - Fix timestamp value for RTC_TIMESTAMP_BEGIN_1900

   - Use SPDX identifier for the core

   - validate upper bound of tm->tm_year

  New driver:

   - Aspeed BMC SoC RTC

  Drivers:

   - abx80x: use rtc_add_group

   - ds3232: nvram support

   - pcf85063: add alarm, nvram, offset correction and microcrystal
     rv8263 support

   - x1205: add of_match_table

   - Use set_time instead of set_mms/set_mmss64 for: ab3100, coh901331,
     digicolor, ds1672, ds2404, ep93xx, imxdi, jz4740, lpc32xx, mc13xxx,
     mxc, pcap, stmp3xxx, test, wm831x, xgene.

   - Set RTC range for: ab3100, at91sam9, coh901331, da9063, digicolor,
     dm355evm, ds1672, ds2404, ep39xx, goldfish, imxdi, jz4740, lpc32xx,

     stmp3xxx, sun4v, tegra, wm831x, xgene.

   - Switch to rtc_time64_to_tm/rtc_tm_to_time64 for the driver that
     properly set the RTC range.

   - Use dev_get_drvdata instead of multiple indirections"

stat command with soft mount never return after server is stopped.

When alloc a new client, the state of the client will be set to
NFS4CLNT_LEASE_EXPIRED.

When the server is stopped, the state manager will work, and accord
the state to recover. But the state is NFS4CLNT_LEASE_EXPIRED, it
will drain the slot table and lead other task to wait queue, until
the client recovered. Then the stat command is hung.

When discover server trunking, the client will renew the lease,
but check the client state, it lead the client state corruption.

So, we need to call state manager to recover it when detect server
ip trunking.

The problem is caused by the ptrace_signal() call in the for loop
in get_signal(). There is a cgroup_enter_frozen() call inside
ptrace_signal(), so after exit from ptrace_signal() the task->frozen
bit might be set. In this case do_group_exit() can be called with the
task->frozen bit set and trigger the warning. This is only place where
we can leave the loop with the task->frozen bit set and without
setting JOBCTL_TRAP_FREEZE and TIF_SIGPENDING.

To resolve this problem, let's move cgroup_leave_frozen(true) call to
just after the fatal label. If the task is going to die, the frozen
bit must be cleared no matter how we get into this point.

ASoC: Fixes for v5.2

A bunch of driver specific fixes that came in since the initial pull
request for v5.2, mainly warning fixes for the newly added Sound Open
Firmware code which people appeared to only start looking at after I'd
sent the pull request.

Pull drm updates from Dave Airlie:
 "This has two exciting community drivers for ARM Mali accelerators.
  Since ARM has never been open source friendly on the GPU side of the
  house, the community has had to create open source drivers for the
  Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
  series. Well done to all involved and hopefully this will help ARM
  head in the right direction.

  There is also now the ability if you don't have any of the legacy
  drivers enabled (pre-KMS) to remove all the pre-KMS support code from
  the core drm, this saves 10% or so in codesize on my machine.

  i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
  moves out of staging.

  There are also some rcar-du patches which crossover with media tree
  but all should be acked by Mauro.

  Summary:

 "Finally deprecate the legacy IDE layer"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/ide:
  ide: officially deprecated the legacy IDE driver

This is the 2nd pull request for the malidp-next. The new patches add
additional support for Arm Mali D71 so that it can now be enabled
correctly and brought up on any SoC that contains the IP. From now on
we will start focusing on adding writeback, scaling and other useful
features to bring the driver to the same level of maturity as mali-dp.

After a recent chat with Dave we agreed to try to finally kill off the
legacy IDE code base.  Set a two year grace period in which we try
to move everyone over.  There are a few pieces of hardware not
supported by libata yet, but for many of them we aren't even sure
if there are any users.  For those that have users we have usually
found a volunteer to add libata support.

Pull MIPS updates from Paul Burton:

 - A set of memblock initialization improvements thanks to Serge Semin,
   tidying up after our conversion from bootmem to memblock back in
   v4.20.

 - Our eBPF JIT the previously supported only MIPS64r2 through MIPS64r5
   is improved to also support MIPS64r6. Support for MIPS32 systems is
   introduced, with the caveat that it only works for programs that
   don't use 64 bit registers or operations - those will bail out & need
   to be interpreted.

 - Improvements to the allocation & configuration of our exception
   vector that should fix issues seen on some platforms using recent
   versions of U-Boot.

 - Some minor improvements to code generated for jump labels, along with
   enabling them by default for generic kernels.

      iozone performance regression.

   - "gfs2: read journal in large chunks"
     "gfs2: fix race between gfs2_freeze_func and unmount"

      An improved version of a commit we also ended up reverting in 5.0
      because of a regression in xfstest generic/311. It turns out that
      the journal changes were mostly innocent and that unfreeze didn't
      wait for the freeze to complete, which caused the filesystem to be
      unmounted before it was actually idle.

While PCAP_RTC_DAY_MASK is set to 0x3ffff, it is very unlikely to be
correct as this ends in june 1992, before the product even existed. It is
more likely to be a 14-bit day counter. The next product in the family (the
mc13xxx) has a 15-bit day counter.

The same issue is seen with PCAP_RTC_TOD_MASK which only has 65535 seconds
and falls short of the necessary 86400 seconds.
