At the very end of the MACsec block initialization in the MSCC PHY
driver, the MACsec "protocol mode" is set. This setting should be set
based on the PHY id within the package, as the bank used to access the
register used depends on this. This was not done correctly, and only the
first bank was used leading to the two upper PHYs being unstable when
using the VSC8584. This patch fixes it.

Commit 14b41a2959 ("net: stmmac: Delete txtimer in suspend") was the
first attempt to fix a race between mod_timer() and setup_timer()
during stmmac_resume(). However the issue still exists as the commit
only addressed half of the issue.
Same race can still happen as stmmac_resume() re-attaches interface
way too early - even before hardware is fully initialized. Worse,
doing so allows network traffic to restart and stmmac_tx_timer_arm()
being called in the middle of stmmac_resume(), which re-init tx timers
in stmmac_init_coalesce(). timer_list will be corrupted and system
crashes as a result of race between mod_timer() and setup_timer().

Ever since its first commit 0ca7111a38 ("phy: add AT803x driver") the
PHY ID mask was set to 0xffffffef. It is unclear to me why this mask was
chosen in the first place. Both the AR8031/AR8033 and the AR8035
datasheets mention it is always the given value:
- for AR8031/AR8033 its 0x004d/0xd074
- for AR8035 its 0x004d/0xd072
Unfortunately, I don't have a datasheet for the AR8030. Therefore, we
leave its PHY ID mask untouched. For the PHYs mentioned before use the
handy PHY_ID_MATCH_EXACT() macro.
I've tried to contact the author of the initial commit, but received no

But since sparc32 has only three actual page table levels, pgd, p4d and
pud are essentially the same thing and pgd_offset() and p4d_offset() are
no-ops, the __nocache_fix() should be done only at PUD level.
Remove __nocache_fix() for p4d_offset() and pud_offset() and keep it

Refactor how address space initialization works. Instead of having the
address space function create the MMU object (and thus require separate but
equal functions for gpummu and iommu) use a single function and pass the
MMU struct in. Make the generic code cleaner by using target specific
functions to create the address space so a2xx can do its own thing in its
own space. For all the other targets use a generic helper to initialize
IOMMU but leave the door open for newer targets to use customization
if they need it.

Since sparc32 has only 3 page table levels, the PGD and PUD are

init_vp_index() uses the (per-node) hv_numa_map[] masks to record the
CPUs allocated for channel interrupts at a given time, and distribute
the performance-critical channels across the available CPUs: in part.,
the mask of "candidate" target CPUs in a given NUMA node, for a newly
offered channel, is determined by XOR-ing the node's CPU mask and the
node's hv_numa_map. This operation/mechanism assumes that no offline
CPUs is set in the hv_numa_map mask, an assumption that does not hold
since such mask is currently not updated when a channel is removed or
assigned to a different CPU.
To address the issues described above, this adds hooks in the channel
removal path (hv_process_channel_removal()) and in target_cpu_store()
in order to clear, resp. to update, the hv_numa_map[] masks as needed.
This also adds a (missed) update of the masks in init_vp_index() (cf.,
e.g., the memory-allocation failure path in this function).
Like in the case of init_vp_index(), such hooks require to determine
if the given channel is performance critical. init_vp_index() does
this by parsing the channel's offer, it can not rely on the device
data structure (device_obj) to retrieve such information because the
device data structure has not been allocated/linked with the channel
by the time that init_vp_index() executes. A similar situation may
hold in hv_is_alloced_cpu() (defined below); the adopted approach is
to "cache" the device type of the channel, as computed by parsing the
channel's offer, in the channel structure itself.

vmbus_process_offer() does two things (among others):
1) first, it sets the channel's target CPU with cpu_hotplug_lock;
2) it then adds the channel to the channel list(s) with channel_mutex.
Since cpu_hotplug_lock is released before (2), the channel's target CPU
(as designated in (1)) can be deemed "free" by hv_synic_cleanup() and go
offline before the channel is added to the list.
Fix the race condition by "extending" the cpu_hotplug_lock critical
section to include (2) (and (1)), nesting the channel_mutex critical
section within the cpu_hotplug_lock critical section as done elsewhere
(hv_synic_cleanup(), target_cpu_store()) in the hyperv drivers code.
Move even further by extending the channel_mutex critical section to
include (1) (and (2)): this change allows to remove (the now redundant)
bind_channel_to_cpu_lock, and generally simplifies the handling of the
target CPUs (that are now always modified with channel_mutex held).

Third set of IIO new device support, cleanups etc for the 5.8 cycle.
A rather late final set to pick up a couple of new drivers, a bunch
of cleanup and some fixes that can wait for the merge window.
In particularly I'd like to highlight the great core and driver
cleanup work that the Alex and the team at Analog devices are currently
doing. Should see lots more of that in the next cycle give what is
currently under review.
This pull also has the first few fixes squashing a class of alignment
and small kernel data leak bugs that Lars-Peter Clausen picked up
on in a review. Quite a few more of those to come. They've been
there a long time so we aren't rushing the reviews.
New device support
* atlas ezo
- new driver supporting this range of chemical and similar sensors
with the odd interface of ascii strings over i2c.
* bma180
- bma023, bma150 and smb380 support. Note these are currently also
supported by a driver in input which we will hopefully remove
(eventually). There are Kconfig protections to avoid a clash
in the meantime.
* vcnl3020
- new driver for this proximity sensor.
Core change
* during buffer updates, change the current state variable before
we actually call pre and post enable callbacks so drivers can know
where we are going. Note this is a precursor to only exposing
one enable callback to drivers. The (false) logic behind having two
such callbacks has long been fixed, but only now is the mess getting
cleaned up.
Features
* exynos adc.
- add reporting of channels scale values.
Cleanups and minor fixes.
* core
- drop now unused attrcount_orig variable.
* ad5360, ad5446, ad5449, ad5755, ad5761, ad5764, ad5380, ad5421,
ad5592, ad5686 and vf610_dac
- remove direct use of iio_dev->mlock from all these drivers.
Its semantics used to be poorly defined, but now it is for core
use only. Removing it's use in drivers has been a long process
of which this is the latest step!
* exynos_adc
- drop a pointless check on the phy as the driver doesn't access it.
* ping
- avoid a dance from iio_priv and iio_priv_to_dev back again by
just passing the iio_dev into the functions.
* pms7003
- alignment and potential data leak fix.
* sps30

On some architectures like ppc64le and aarch64, compiling with
-Wformat=1 will throw the following warnings:

So, fix that with a typecast.

The driver was using rq_last_status where it should have been
using sq_last_status. Fix the string to be using the correct
error reporting variable.

The "ethtool -d" handler reads registers in the ice_regs_dump_list array
and returns read values back to the userspace.
The register offsets PFINT0_ITR* are not valid as per the specification
and reading these causes a "unable to handle kernel paging request" bug
in the driver. Remove these registers from ice_regs_dump_list.

Require the Dynamic Device Personalization (DDP) file to have the same
major version number and the same or older minor number than the firmware
version major and minor, respectively.
Check the OS and NVM package versions before downloading the package.
If the OS package version is not compatible with NVM then return an
appropriate error.
Split the 32-byte segment name into a 28-byte segment name and
a 4-byte Track-ID. Older packages will still work with this change
because no package has a name that will take up more than 28 bytes;
in this case the Track-ID will be 0.
Note that the driver will store the segment name as 32-bytes in the
ice_hw structure, in order to normalize the length of the various
package name strings that it uses.
Also add section ID and structure for the segment metadata section.

Currently if a unicast MAC is set via ndo_set_vf_mac, the PF driver will
set the VF's dflt_lan_addr.addr once some basic checks have passed. The
VF is then reset. During reset the PF driver will attempt to program the
VF's MAC from the dflt_lan_addr.addr field. This fails when the MAC
already exists on the PF's switch.
This is causing the VF to be completely disabled until removing/enabling
any VFs via sysfs.
Fix this by checking if the unicast MAC exists before triggering a VF
reset directly in ndo_set_vf_mac. Also, add a check if the unicast MAC
is set to the same value as before and return 0 if that is the case.

Currently if the iavf is loaded and a VF link transitions from up to
down to up again a Tx timeout will be triggered. This happens because
Tx/Rx queue interrupts are only enabled when receiving the
VIRTCHNL_OP_CONFIG_MAP_IRQ message, which happens on reset or initial
iavf driver load, but not when bringing link up. This is problematic
because they are disabled on the VIRTCHNL_OP_DISABLE_QUEUES message,
which is part of bringing a VF's link down. However, they are not
enabled on the VIRTCHNL_OP_ENABLE_QUEUES message, which is part of
bringing a VF's link up.
Fix this by re-enabling the VF's Rx and Tx queue interrupts when they
were previously configured. This is done by first checking to make
sure the previous value in QINT_[R|T]QCTL.MSIX_INDX is not 0, which
is used to represent the OICR in the VF's interrupt space. If the
MSIX_INDX is non-zero then enable the interrupt by setting the
QINT_[R|T]CTL.CAUSE_ENA bit to 1.

Rx MDD auto reset message was not being logged because logging occurred
after the VF reset and the VF MDD data was reinitialized.
Log the Rx MDD auto reset message before triggering the VF reset.
