A BPF program is required to check the return register of a
map_elem_lookup() call before accessing memory. The verifier keeps
track of this by converting the type of the result register from
PTR_TO_MAP_VALUE_OR_NULL to PTR_TO_MAP_VALUE after a conditional
jump ensures safety. This check is currently exclusively performed
for the result register 0.
In the event the compiler reorders instructions, BPF_MOV64_REG
instructions may be moved before the conditional jump which causes
them to keep their type PTR_TO_MAP_VALUE_OR_NULL to which the
verifier objects when the register is accessed:
This commit extends the verifier to keep track of all identical
PTR_TO_MAP_VALUE_OR_NULL registers after a map_elem_lookup() by
assigning them an ID and then marking them all when the conditional
jump is observed.

Robert Jarzmik says:
====================
support smc91x on mainstone and devicetree
This series aims at bringing support to mainstone board on a
device-tree based build, as what is already in place for legacy
mainstone.
The bulk of the mainstone "specific" behavior is that a u16 write
doesn't work on a address of the form 4*n + 2, while it works on 4*n.
The legacy workaround was in SMC_outw(), with calls to
machine_is_mainstone(). These calls don't work with a pxa27x-dt
machine type, which is used when a generic device-tree pxa27x machine
is used to boot the mainstone board.
Therefore, this series enables the smc91c111 adapter of the mainstone
board to work on a device-tree build, exaclty as it's been working for
years with the legacy arch/arm/mach-pxa/mainstone.c definition.
As a sum up, this extends an existing mechanism to device-tree based
pxa platforms.

When the BUG is converted to a WARN_ON it shows 4 missing adjacencies:
eth3 - myvrf, mvrf - eth3, bond1 - myvrf and myvrf - bond1
All of those are because the __netdev_upper_dev_link function does not
properly link macvlan lower devices to myvrf when it is enslaved.
The second case just flips the ordering of the enslavements:
ip link set bond1 master bridge
ip link set macvlan master myvrf
Then run:
ip link delete bond1
ip link delete myvrf
The vrf delete command hangs because myvrf has a reference that has not
been released. In this case the removal code does not account for 2 paths
between eth3 and myvrf - one from bridge to vrf and the other through the
macvlan.
Rather than try to maintain a linked list of all upper and lower devices
per netdevice, only track the direct neighbors. The remaining stack can
be determined by recursively walking the neighbors.
The existing netdev_for_each_all_upper_dev_rcu,
netdev_for_each_all_lower_dev and netdev_for_each_all_lower_dev_rcu macros
are replaced with APIs that walk the upper and lower device lists. The
new APIs take a callback function and a data arg that is passed to the
callback for each device in the list. Drivers using the old macros are
converted in separate patches to make it easier on reviewers. It is an
API conversion only; no functional change is intended.

Andrew Lunn says:
====================
Interrupt support for mv88e6xxx
This patchset add interrupt controller support to the MV88E6xxx. This
allows access to the interrupts the internal PHY generate. These
interrupts can then be associated to a PHY device in the device tree
and used by the PHY lib, rather than polling.
Since interrupt handling needs to make MDIO bus accesses, threaded
interrupts are used. The phylib needs to request the PHY interrupt
using the threaded IRQ API. This in term allows some simplification to
the code, in that the phylib interrupt handler can directly call
phy_change(), rather than use a work queue. The work queue is however
retained for the phy_mac_interrupt() call, which can be called in hard
interrupt context.
Since RFC v1:
Keep phy_mac_interrupt() callable in hard IRQ context.
The fix to trigger the phy state machine transitions on interrupts has
already been submitted, so is dropped from here.
Added back shared interrupts support.

Malicious VFs might be caught in several different methods:
- Misusing their bar permission and being blocked by hardware.
- Misusing their fastpath logic and being blocked by firmware.
- Misusing their interaction with their PF via hw-channel,
and being blocked by PF driver.
On the first two items, firmware would indicate to driver that
the VF is to be considered malicious, but would sometime still
allow the VF to communicate with the PF [depending on the exact
nature of the malicious activity done by the VF].
The current existing logic on the PF side lacks handling of such events,
and might allow the PF to perform some incorrect configuration on behalf
of a VF that was previously indicated as malicious.
The new scheme is simple -
Once the PF determines a VF is malicious it would:
a. Ignore any further requests on behalf of the VF-driver.
b. Prevent any configurations initiated by the hyperuser for
the malicious VF, as firmware isn't willing to serve such.
The malicious indication would be cleared upon the VF flr,
after which it would become usable once again.

the driver is going to sleep at least 5ms between each iteration

However, in almost every configuration scenario the firmware
would be able to comply and complete the ramrod in a manner of
several usecs. This is especially important in cases where there
might be a lot of sequential configurations applying to the hardware
[e.g., RoCE], in which case the existing scheme might cause some
visible user delays.

Pull NFS client updates from Anna Schumaker:
"Highlights include:
Stable bugfixes:
- sunrpc: fix writ espace race causing stalls
- NFS: Fix inode corruption in nfs_prime_dcache()
- NFSv4: Don't report revoked delegations as valid in nfs_have_delegation()
- NFSv4: nfs4_copy_delegation_stateid() must fail if the delegation is invalid
- NFSv4: Open state recovery must account for file permission changes
- NFSv4.2: Fix a reference leak in nfs42_proc_layoutstats_generic
Features:
- Add support for tracking multiple layout types with an ordered list
- Add support for using multiple backchannel threads on the client
- Add support for pNFS file layout session trunking
- Delay xprtrdma use of DMA API (for device driver removal)
- Add support for xprtrdma remote invalidation
- Add support for larger xprtrdma inline thresholds
- Use a scatter/gather list for sending xprtrdma RPC calls
- Add support for the CB_NOTIFY_LOCK callback
- Improve hashing sunrpc auth_creds by using both uid and gid
Bugfixes:
- Fix xprtrdma use of DMA API
- Validate filenames before adding to the dcache
- Fix corruption of xdr->nwords in xdr_copy_to_scratch
- Fix setting buffer length in xdr_set_next_buffer()
- Don't deadlock the state manager on the SEQUENCE status flags
- Various delegation and stateid related fixes
- Retry operations if an interrupted slot receives EREMOTEIO
- Make nfs boot time y2038 safe"
