Pull ARM SoC platform updates from Olof Johansson:
 "SoC changes, a substantial part of this is cleanup of some of the
  older platforms that used to have a bunch of board files.

  In particular:

   - Remove non-DT i.MX platforms that haven't seen activity in years,
     it's time to remove them.

   - A bunch of cleanup and removal of platform data for TI/OMAP
     platforms, moving over to genpd for power/reset control (yay!)

   - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
     closer to multiplatform support (not quite there yet, but getting
     close).

  There are a few other changes too, smaller fixlets, etc. For new
  platform support, the primary ones are:

Quoting https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html:

  You can define a local register variable and associate it with a
  specified register...

  The only supported use for this feature is to specify registers for
  input and output operands when calling Extended asm (see Extended
  Asm). This may be necessary if the constraints for a particular
  machine don't provide sufficient control to select the desired
  register.

On 32-bit x86, this is used to ensure that gcc will put an 8-byte value
into the %edx:%eax pair, while all other cases will just use the single
register %eax (%rax on x86-64).  While the _ASM_AX actually just expands
to "%eax", note this comment next to get_user() which does something
very similar:

 * The use of _ASM_DX as the register specifier is a bit of a
 * simplification, as gcc only cares about it as the starting point
 * and not size: for a 64-bit value it will use %ecx:%edx on 32 bits
 * (%ecx being the next register in gcc's x86 register sequence), and
 * %rdx on 64 bits.

However, getting this to work requires that there is no code between the
assignment to the local register variable and its use as an input to the
asm() which can possibly clobber any of the registers involved -
including evaluation of the expressions making up other inputs.

In the current code, the ptr expression used directly as an input may
cause such code to be emitted.  For example, Sean Christopherson
observed that with KASAN enabled and ptr being current->set_child_tid
(from chedule_tail()), the load of current->set_child_tid causes a call
to __asan_load8() to be emitted immediately prior to the __put_user_4
call, and Naresh Kamboju reports that various mmstress tests fail on
KASAN-enabled builds.

It's also possible to synthesize a broken case without KASAN if one uses
"foo()" as the ptr argument, with foo being some "extern u64 __user
*foo(void);" (though I don't know if that appears in real code).

Fix it by making sure ptr gets evaluated before the assignment to
__val_pu, and add a comment that __val_pu must be the last thing
computed before the asm() is entered.

     which changed with the 5.10 PR from the usb subsystem

  Current release regressions:

   - Revert "virtio-net: ethtool configurable RXCSUM", it was causing
     crashes at probe when control vq was not negotiated/available

  Previous release regressions:

   - ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO

   - nexthop: Fix performance regression in nexthop deletion by

Apply the outstanding statfs changes in the journal head to the
master statfs file. Zero out the local statfs file for good measure.

Previously, statfs updates would be read in from the local statfs inode and
synced to the master statfs inode during recovery.

We now use the statfs updates in the journal head to update the master statfs
inode instead of reading in from the local statfs inode. To preserve backward
compatibility with kernels that can't do this, we still need to keep the
local statfs inode up to date by writing changes to it. At some point in the
future, we can do away with the local statfs inodes altogether and keep the
statfs changes solely in the journal.

We need to lookup the master statfs inode and the local statfs
inodes earlier in the mount process (in init_journal) so journal
recovery can use them when it attempts to recover the statfs info.
We lookup all the local statfs inodes and store them in a linked
list to allow a node to recover statfs info for other nodes in the
cluster.

When KVM maps a largepage backed region at a lower level in order to
make it executable (i.e. NX large page shattering), it reduces the TLB
performance of that region. In order to avoid making this degradation
permanent, KVM must periodically reclaim shattered NX largepages by
zapping them and allowing them to be rebuilt in the page fault handler.

With this patch, the TDP MMU does not respect KVM's rate limiting on
reclaim. It traverses the entire TDP structure every time. This will be
addressed in a future patch.

Direct roots don't have a write flooding count because the guest can't

Dirty logging ultimately breaks down MMU mappings to 4k granularity.
When dirty logging is no longer needed, these granaular mappings
represent a useless performance penalty. When dirty logging is disabled,
search the paging structure for mappings that could be re-constituted
into a large page mapping. Zap those mappings so that they can be
faulted in again at a higher mapping level.
