a04aead144 KVM: nSVM: fix running nested guests when npt=0
In case of npt=0 on host, nSVM needs the same .inject_page_fault tweak
as VMX has, to make sure that shadow mmu faults are injected as vmexits.

It is not clear why this is needed at all, but for now keep the same
code as VMX and we'll fix it for both.

Based on a patch by Maxim Levitsky <mlevitsk@redhat.com>.

1aaca37e1e KVM: VMX: Allow INVPCID in guest without PCID
Remove the restriction that prevents VMX from exposing INVPCID to the
guest without PCID also being exposed to the guest.  The justification of
the restriction is that INVPCID will #UD if it's disabled in the VMCS.
While that is a true statement, it's also true that RDTSCP will #UD if
it's disabled in the VMCS.  Neither of those things has any dependency
whatsoever on the guest being able to set CR4.PCIDE=1, which is what is
effectively allowed by exposing PCID to the guest.

Removing the bogus restriction aligns VMX with SVM, and also allows for
an interesting configuration.  INVPCID is that fastest way to do a global
TLB flush, e.g. see native_flush_tlb_global().  Allowing INVPCID without
PCID would let a guest use the expedited flush while also limiting the
number of ASIDs consumed by the guest.

67fc209b52 cpufreq: qcom-hw: drop devm_xxx() calls from init/exit hooks
Commit f17b3e4432 ("cpufreq: qcom-hw: Use
devm_platform_ioremap_resource() to simplify code") introduces
a regression on platforms using the driver, by failing to initialise
a policy, when one is created post hotplug.

When all the CPUs of a policy are hoptplugged out, the call to .exit()
and later to devm_iounmap() does not release the memory region that was
requested during devm_platform_ioremap_resource().  Therefore,
a subsequent call to .init() will result in the following error, which
will prevent a new policy to be initialised:

With that being said, the original code was tricky and skipping memory
region request intentionally to hide this issue.  The true cause is that
those devm_xxx() device managed functions shouldn't be used for cpufreq
init/exit hooks, because &pdev->dev is alive across the hooks and will
not trigger auto resource free-up.  Let's drop the use of device managed
functions and manually allocate/free resources, so that the issue can be
fixed properly.

88f38846bf HID: wacom: Ignore attempts to overwrite the touch_max value from HID
The `wacom_feature_mapping` function is careful to only set the the
touch_max value a single time, but this care does not extend to the
`wacom_wac_finger_event` function. In particular, if a device sends
multiple HID_DG_CONTACTMAX items in a single feature report, the
driver will end up retaining the value of last item.

The HID descriptor for the Cintiq Companion 2 does exactly this. It
incorrectly sets a "Report Count" of 2, which will cause the driver
to process two HID_DG_CONTACTCOUNT items. The first item has the actual
count, while the second item should have been declared as a constant
zero. The constant zero is the value the driver ends up using, however,
since it is the last HID_DG_CONTACTCOUNT in the report.

    Report ID (16),
    Usage (Contact Count Maximum),  ; Contact count maximum (55h, static value)
    Report Count (2),
    Logical Maximum (10),
    Feature (Variable),

To address this, we add a check that the touch_max is not already set
within the `wacom_wac_finger_event` function that processes the
HID_DG_TOUCHMAX item. We emit a warning if the value is set and ignore
the updated value.

This could potentially cause problems if there is a tablet which has
a similar issue but requires the last item to be used. This is unlikely,
however, since it would have to have a different non-zero value for
HID_DG_CONTACTMAX earlier in the same report, which makes no sense
except in the case of a firmware bug. Note that cases where the
HID_DG_CONTACTMAX items are in different reports is already handled
(and similarly ignored) by `wacom_feature_mapping` as mentioned above.

de04241ab8 opp: Don't skip freq update for different frequency
We skip the OPP update if the current and target OPPs are same. This is
fine for the devices that don't support frequency but may cause issues
for the ones that need to program frequency.

An OPP entry doesn't really signify a single operating frequency but
rather the highest frequency at which the other properties of the OPP
entry apply. And we may reach here with different frequency values,
while all of them would point to the same OPP entry in the OPP table.

We just need to update the clock frequency in that case, though in order
to not add special exit points we reuse the code flow from a normal
path.

While at it, rearrange the conditionals in the 'if' statement to check
'enabled' flag at the end.

059c01039c zonefs: Fix file size of zones in full condition
Per ZBC/ZAC/ZNS specifications, write pointers may not have valid values
when zones are in full condition. However, when zonefs mounts a zoned
block device, zonefs refers write pointers to set file size even when
the zones are in full condition. This results in wrong file size. To fix
this, refer maximum file size in place of write pointers for zones in
full condition.

In case a PCI host driver's probe is deferred, the same I/O range may be
allocated again, and be ignored, causing a memory leak.

Fix this by (a) letting logic_pio_register_range() return -EEXIST if the
passed range already exists, so pci_register_io_range() will free it, and
by (b) making pci_register_io_range() not consider -EEXIST an error
condition.

41f1a01bb6 Merge branch 'ptp-ptp_clockmatrix-Fix-output-1-PPS-alignment'
Vincent Cheng says:

====================
ptp: ptp_clockmatrix: Fix output 1 PPS alignment.

This series fixes a race condition that may result in the output clock
not aligned to internal 1 PPS clock.

Part of device initialization is to align the rising edge of output
clocks to the internal rising edge of the 1 PPS clock.  If the system
APLL and DPLL are not locked when this alignment occurs, the alignment
fails and a fixed offset between the internal 1 PPS clock and the
output clock occurs.

If a clock is dynamically enabled after power-up, the output clock
also needs to be aligned to the internal 1 PPS clock.

Samuel Holland says:

====================
dwmac-sun8i cleanup and shutdown hook

These patches clean up some things I noticed while fixing suspend/resume
behavior. The first four are minor code improvements. The last one adds
a shutdown hook to minimize power consumption on boards without a PMIC.

Changes v1 to v2:
  - Note the assumption of exclusive reset controller access in patch 3

96be41d74f net: stmmac: dwmac-sun8i: Add a shutdown callback
The Ethernet MAC and PHY are usually major consumers of power on boards
which may not be able to fully power off (those with no PMIC). Powering
down the MAC and internal PHY saves power while these boards are "off".

4fc7ec31c3 gfs2: Use resource group glock sharing
This patch takes advantage of the new glock holder sharing feature for
resource groups.  We have already introduced local resource group
locking in a previous patch, so competing accesses of local processes
are already under control.

06e908cd9e gfs2: Allow node-wide exclusive glock sharing
Introduce a new LM_FLAG_NODE_SCOPE glock holder flag: when taking a
glock in LM_ST_EXCLUSIVE (EX) mode and with the LM_FLAG_NODE_SCOPE flag
set, the exclusive lock is shared among all local processes who are
holding the glock in EX mode and have the LM_FLAG_NODE_SCOPE flag set.
From the point of view of other nodes, the lock is still held
exclusively.

A future patch will start using this flag to improve performance with
rgrp sharing.

725d0e9d46 gfs2: Add per-reservation reserved block accounting
Add a rs_reserved field to struct gfs2_blkreserv to keep track of the number of
blocks reserved by this particular reservation, and a rd_reserved field to
struct gfs2_rgrpd to keep track of the total number of reserved blocks in the
resource group.  Those blocks are exclusively reserved, as opposed to the
rs_requested / rd_requested blocks which are tracked in the reservation tree
(rd_rstree) and which can be stolen if necessary.

When making a reservation with gfs2_inplace_reserve, rs_reserved is set to
somewhere between ap->min_target and ap->target depending on the number of free
blocks in the resource group.  When allocating blocks with gfs2_alloc_blocks,
rs_reserved is decremented accordingly.  Eventually, any reserved but not
consumed blocks are returned to the resource group by gfs2_inplace_release.

07974d2a2a gfs2: Rename rs_{free -> requested} and rd_{reserved -> requested}
We keep track of what we've so far been referring to as reservations in
rd_rstree: the nodes in that tree indicate where in a resource group we'd
like to allocate the next couple of blocks for a particular inode.  Local
processes take those as hints, but they may still "steal" blocks from those
extents, so when actually allocating a block, we must double check in the
bitmap whether that block is actually still free.  Likewise, other cluster
nodes may "steal" such blocks as well.

One of the following patches introduces resource group glock sharing, i.e.,
sharing of an exclusively locked resource group glock among local processes to
speed up allocations.  To make that work, we'll need to keep track of how many
blocks we've actually reserved for each inode, so we end up with two different
kinds of reservations.

Distinguish these two kinds by referring to blocks which are reserved but may
still be "stolen" as "requested".  This rename also makes it more obvious that
rs_requested and rd_requested are strongly related.
