Use readx_poll_timeout_atomic() instead of open coded variants.
While at it, add __iomem attribute to the parameter of pch_gbe_wait_clr_bit().
This in particular will fix a lot of warnings detected by Sparse, e.g.
.../pch_gbe_main.c:308:26: warning: incorrect type in argument 1 (different address spaces)
.../pch_gbe_main.c:308:26: expected void const [noderef] __iomem *
.../pch_gbe_main.c:308:26: got void *reg

While here, drop GPIOF_EXPORT because it's deprecated and

Radu Pirea says:
====================
Add PTP support for TJA1103
This is the PTP support for TJA1103.
The RX timestamp is found in the reserved2 field of the PTP package.
The TX timestamp has to be read from the phy registers. Reading of the
timestamp works with interrupts or with polling(that starts when
.nxp_c45_txtstamp is called).
The implementation of .adjtime is done by read modify write because there
is no way to atomically add/subtract a constant from the clock value.
I've moved scaled_ppm_to_ppb function from ptp_clock.c to
ptp_clock_kernel.h in order to be able to build the driver without
PTP_1588_CLOCK=y.

In each iteration fwnode_for_each_available_child_node() bumps a reference
counting of a loop variable followed by dropping in on a next iteration,
Since in error case the loop is broken, we have to drop a reference count
by ourselves. Do it for port_fwnode in error case during ->probe().

When we call af_ops->set_link_af() we hold a RCU read lock
as we retrieve af_ops from the RCU protected list, but this
is unnecessary because we already hold RTNL lock, which is
the writer lock for protecting rtnl_af_ops, so it is safer
than RCU read lock. Similar for af_ops->validate_link_af().
This was not a problem until we begin to take mutex lock
down the path of ->set_link_af() in __ipv6_dev_mc_dec()
recently. We can just drop the RCU read lock there and
assert RTNL lock.

intel_dp_check_mst_status() uses a 14-byte array to read the DPRX Event
Status Indicator data, but then passes that buffer at offset 10 off as
an argument to drm_dp_channel_eq_ok().
End result: there are only 4 bytes remaining of the buffer, yet
drm_dp_channel_eq_ok() wants a 6-byte buffer. gcc-11 correctly warns
about this case:

<linux/kconfig.h> is included from all the kernel-space source files,
including C, assembly, linker scripts. It is intended to contain a
minimal set of macros to evaluate CONFIG options.
IF_ENABLED() is an intruder here because (x ? y : z) is C code, which
should not be included from assembly files or linker scripts.
Also, <linux/kconfig.h> is no longer self-contained because NULL is
defined in <linux/stddef.h>.
Move IF_ENABLED() out to <linux/kernel.h> as PTR_IF(). PTF_IF()
takes the general boolean expression instead of a CONFIG option
so that it fits better in <linux/kernel.h>.

The RX FIFO overflows when the system is not able to process all received
packets and they start accumulating (first in the DMA queue in memory,
then in the FIFO). An interrupt is then raised for each overflowing packet
and handled in stmmac_interrupt(). This is counter-productive, since it
brings the system (or more likely, one CPU core) to its knees to process
the FIFO overflow interrupts.
stmmac_interrupt() handles overflow interrupts by writing the rx tail ptr
into the corresponding hardware register (according to the MAC spec, this
has the effect of restarting the MAC DMA). However, without freeing any rx
descriptors, the DMA stops right away, and another overflow interrupt is
raised as the FIFO overflows again. Since the DMA is already restarted at
the end of stmmac_rx_refill() after freeing descriptors, disabling FIFO
overflow interrupts and the corresponding handling code has no side effect,
and eliminates the interrupt storm when the RX FIFO overflows.

If userspace exits before calling accept() on a listener that had at least
one new connection ready, we get:
Attempt to release TCP socket in state 8
This happens because the mptcp socket gets cloned when the TCP connection
is ready, but the socket is never exposed to userspace.
The client additionally sends a DATA_FIN, which brings connection into
CLOSE_WAIT state. This in turn prevents the orphan+state reset fixup
in mptcp_sock_destruct() from doing its job.

"A mix of fixes and clean-ups that turned up too late for the first
pull request:
- Restore terminal stack frame records. Their previous removal caused
traces which cross secondary_start_kernel to terminate one entry
too late, with a spurious "0" entry.
- Fix boot warning with pseudo-NMI due to the way we manipulate the
PMR register.
- ACPI fixes: avoid corruption of interrupt mappings on watchdog
probe failure (GTDT), prevent unregistering of GIC SGIs.
- Force SPARSEMEM_VMEMMAP as the only memory model, it saves with
having to test all the other combinations.
- Documentation fixes and updates: tagged address ABI exceptions on
brk/mmap/mremap(), event stream frequency, update booting
requirements on the configuration of traps"

Remove filters from being setup in case of software DCB and allow the
LLDP frames to be properly transmitted to the wire.
It is not possible to transmit the LLDP frame out of the port, if they
are filtered by control VSI. This prohibits software LLDP agent
properly communicate its DCB capabilities to the neighbors.

Commit 12738ac4754e ("i40e: Fix sparse errors in i40e_txrx.c") broke
XDP support in the i40e driver. That commit was fixing a sparse error
in the code by introducing a new variable xdp_res instead of
overloading this into the skb pointer. The problem is that the code
later uses the skb pointer in if statements and these where not
extended to also test for the new xdp_res variable. Fix this by adding
the correct tests for xdp_res in these places.
The skb pointer was used to store the result of the XDP program by
overloading the results in the error pointer
ERR_PTR(-result). Therefore, the allocation failure test that used to
only test for !skb now need to be extended to also consider !xdp_res.
i40e_cleanup_headers() had a check that based on the skb value being
an error pointer, i.e. a result from the XDP program != XDP_PASS, and
if so start to process a new packet immediately, instead of populating
skb fields and sending the skb to the stack. This check is not needed
anymore, since we have added an explicit test for xdp_res being set
and if so just do continue to pick the next packet from the NIC.
