ksz8873_valid_regs[] was added for register access for KSZ8863/KSZ8873
switches, but the reset register is not in the list so
ksz8_reset_switch() does not take any effect.
Replace regmap_update_bits() using ksz_regmap_8 with ksz_rmw8() so that
an error message will be given if the register is not defined.
A side effect of not resetting the switch is the static MAC table is not
cleared. Further additions to the table will show write error as there
are only 8 entries in the table.

The variable ret in icss_iep_extts_enable() was incorrectly declared
as u32, while the function returns int and may return negative error
codes. This will cause sign extension issues and incorrect error
propagation. Update ret to be int to fix error handling.
This change corrects the declaration to avoid potential type mismatch.

Page pool can have pages "directly" (locklessly) recycled to it,
if the NAPI that owns the page pool is scheduled to run on the same CPU.
To make this safe we check that the NAPI is disabled while we destroy
the page pool. In most cases NAPI and page pool lifetimes are tied
together so this happens naturally.
The queue API expects the following order of calls:
-> mem_alloc
alloc new pp
-> stop
napi_disable
-> start
napi_enable
-> mem_free
free old pp
Here we allocate the page pool in ->mem_alloc and free in ->mem_free.
But the NAPIs are only stopped between ->stop and ->start. We created
page_pool_disable_direct_recycling() to safely shut down the recycling
in ->stop. This way the page_pool_destroy() call in ->mem_free doesn't
have to worry about recycling any more.
Unfortunately, the page_pool_disable_direct_recycling() is not enough
to deal with failures which necessitate freeing the _new_ page pool.
If we hit a failure in ->mem_alloc or ->stop the new page pool has
to be freed while the NAPI is active (assuming driver attaches the
page pool to an existing NAPI instance and doesn't reallocate NAPIs).
Freeing the new page pool is technically safe because it hasn't been
used for any packets, yet, so there can be no recycling. But the check
in napi_assert_will_not_race() has no way of knowing that. We could
check if page pool is empty but that'd make the check much less likely
to trigger during development.
Add page_pool_enable_direct_recycling(), pairing with
page_pool_disable_direct_recycling(). It will allow us to create the new
page pools in "disabled" state and only enable recycling when we know
the reconfig operation will not fail.
Coincidentally it will also let us re-enable the recycling for the old
pool, if the reconfig failed:
-> mem_alloc (new)
-> stop (old)
# disables direct recycling for old
-> start (new)
# fail!!
-> start (old)
# go back to old pp but direct recycling is lost :(
-> mem_free (new)
The new helper is idempotent to make the life easier for drivers,
which can operate in HDS mode and support zero-copy Rx.
The driver can call the helper twice whether there are two pools
or it has multiple references to a single pool.

When link settings are changed emac->speed is populated by
emac_adjust_link(). The link speed and other settings are then written into
the DRAM. However if both ports are brought down after this and brought up
again or if the operating mode is changed and a firmware reload is needed,
the DRAM is cleared by icssg_config(). As a result the link settings are
lost.
Fix this by calling emac_adjust_link() after icssg_config(). This re
populates the settings in the DRAM after a new firmware load.

Currently, after modifying device port mode, the np_link_ok state
is immediately checked. At this point, the device may not yet ready,
leading to the querying of an intermediate state.
This patch will poll to check if np_link is ok after
modifying device port mode, and only report np_link_fail upon timeout.

When the network port is down, the queue is released, and ring->len is 0.
In debugfs, hbg_get_queue_used_num() will be called,
which may lead to a division by zero issue.
This patch adds a check, if ring->len is 0,
hbg_get_queue_used_num() directly returns 0.

Currently, the hibmcge netdev acquires the rtnl_lock in
pci_error_handlers.reset_prepare() and releases it in
pci_error_handlers.reset_done().
However, in the PCI framework:
pci_reset_bus - __pci_reset_slot - pci_slot_save_and_disable_locked -
pci_dev_save_and_disable - err_handler->reset_prepare(dev);
In pci_slot_save_and_disable_locked():
list_for_each_entry(dev, &slot->bus->devices, bus_list) {
if (!dev->slot || dev->slot!= slot)
continue;
pci_dev_save_and_disable(dev);
if (dev->subordinate)
pci_bus_save_and_disable_locked(dev->subordinate);
}
This will iterate through all devices under the current bus and execute
err_handler->reset_prepare(), causing two devices of the hibmcge driver
to sequentially request the rtnl_lock, leading to a deadlock.
Since the driver now executes netif_device_detach()
before the reset process, it will not concurrently with
other netdev APIs, so there is no need to hold the rtnl_lock now.
Therefore, this patch removes the rtnl_lock during the reset process and
adjusts the position of HBG_NIC_STATE_RESETTING to ensure
that multiple resets are not executed concurrently.

Pull ata fixes from Damien Le Moal:
- Cleanup whitespace in messages in libata-core and the pata_pdc2027x,
pata_macio drivers (Colin)
- Fix ata_to_sense_error() to avoid seeing nonsensical sense data for
rare cases where we fail to get sense data from the drive. The
complementary fix to this is to ensure that we always return the
generic "ABORTED COMMAND" sense data for a failed command for which
we have no status or error fields
- The recent changes to link power management (LPM) which now prevent
the user from attempting to set an LPM policy through the
link_power_management_policy caused some regressions in test
environments because of the error that is now returned when writing
to that attribute when LPM is not supported. To allow users to not
trip on this, introduce the new link_power_management_supported
attribute to allow simple testing of a port/device LPM support (me)

The commit referenced in the Fixes tag causes usbnet to malfunction
(identified via git bisect). Post-commit, my external RJ45 LAN cable
fails to connect. Linus also reported the same issue after pulling that
commit.
The code has a logic error: netif_carrier_on() is only called when the
link is already on. Fix this by moving the netif_carrier_on() call
outside the if-statement entirely. This ensures it is always called
when EVENT_LINK_CARRIER_ON is set and properly clears it regardless
of the link state.

Alex added page bias of LONG_MAX, which is admittedly quite
a clever way of catching overflows of the pp ref count.
The page pool code was "optimized" to leave the ref at 1
for freed pages so it can't catch basic bugs by itself any more.
(Something we should probably address under DEBUG_NET...)
Unfortunately for fbnic since commit f7dc3248dcfb ("skbuff: Optimization
of SKB coalescing for page pool") core _may_ actually take two extra
pp refcounts, if one of them is returned before driver gives up the bias
the ret < 0 check in page_pool_unref_netmem() will trigger.
While at it add a FBNIC_ to the name of the driver constant.

A large DMA mapping request can loop through dma address pinning for
many pages. In cases where THP can not be used, the repeated vmf_insert_pfn can
be costly, so let the task reschedule as need to prevent CPU stalls. Failure to
do so has potential harmful side effects, like increased memory pressure
as unrelated rcu tasks are unable to make their reclaim callbacks and
result in OOM conditions.

This was missed during the initial implementation. The VFIO PCI encodes
the vf_token inside the device name when opening the device from the group
FD, something like:
"0000:04:10.0 vf_token=bd8d9d2b-5a5f-4f5a-a211-f591514ba1f3"
This is used to control access to a VF unless there is co-ordination with
the owner of the PF.
Since we no longer have a device name in the cdev path, pass the token
directly through VFIO_DEVICE_BIND_IOMMUFD using an optional field
indicated by VFIO_DEVICE_BIND_FLAG_TOKEN.

Ever since commit c2ff29e99a76 ("siw: Inline do_tcp_sendpages()"),
we have been doing this:
static int siw_tcp_sendpages(struct socket *s, struct page **page, int offset,
size_t size)
[...]
/* Calculate the number of bytes we need to push, for this page
* specifically */
size_t bytes = min_t(size_t, PAGE_SIZE - offset, size);
/* If we can't splice it, then copy it in, as normal */
if (!sendpage_ok(page[i]))
msg.msg_flags &= ~MSG_SPLICE_PAGES;
/* Set the bvec pointing to the page, with len $bytes */
bvec_set_page(&bvec, page[i], bytes, offset);
/* Set the iter to $size, aka the size of the whole sendpages (!!!) */
iov_iter_bvec(&msg.msg_iter, ITER_SOURCE, &bvec, 1, size);
try_page_again:
lock_sock(sk);
/* Sendmsg with $size size (!!!) */
rv = tcp_sendmsg_locked(sk, &msg, size);
This means we've been sending oversized iov_iters and tcp_sendmsg calls
for a while. This has a been a benign bug because sendpage_ok() always
returned true. With the recent slab allocator changes being slowly
introduced into next (that disallow sendpage on large kmalloc
allocations), we have recently hit out-of-bounds crashes, due to slight
differences in iov_iter behavior between the MSG_SPLICE_PAGES and
"regular" copy paths:
(MSG_SPLICE_PAGES)
skb_splice_from_iter
iov_iter_extract_pages
iov_iter_extract_bvec_pages
uses i->nr_segs to correctly stop in its tracks before OoB'ing everywhere
skb_splice_from_iter gets a "short" read
(!MSG_SPLICE_PAGES)
skb_copy_to_page_nocache copy=iov_iter_count
[...]
copy_from_iter
/* this doesn't help */
if (unlikely(iter->count < len))
len = iter->count;
iterate_bvec
... and we run off the bvecs
Fix this by properly setting the iov_iter's byte count, plus sending the
correct byte count to tcp_sendmsg_locked.

This reverts commit 3b98c9352511db627b606477fc7944b2fa53a165.
Russell says:
Using devm_*() [here] is completely wrong, because this is called
from mdiobus_register_device(). This is not the probe function
for the device, and thus there is no code to trigger the release of
the resource on unregistration.
Moreover, when the mdiodev is eventually probed, if the driver fails
or the driver is unbound, the GPIO will be released, but a reference
will be left behind.
Using devm* with a struct device that is *not* currently being probed
is fundamentally wrong - an abuse of devm.

There are multiple drivers that use the qualcomm mdt loader, but they
have conflicting ideas of how to deal with that dependency when compile-testing
for non-qualcomm targets:
IPA only enables the MDT loader when the kernel config includes ARCH_QCOM,
but the newly added ath12k support always enables it, which leads to a
link failure with the combination of IPA=y and ATH12K=m:
aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_firmware_load':
ipa_main.c:(.text.unlikely+0x134): undefined reference to `qcom_mdt_load

thing.
