When addr_gen_mode is set to IN6_ADDR_GEN_MODE_NONE, the link-local addr
should not be generated. But it isn't the case for GRE (as well as GRE6)
and SIT tunnels. Make it so that tunnels consider the addr_gen_mode,
especially for IN6_ADDR_GEN_MODE_NONE.
Do this in add_v4_addrs() to cover both GRE and SIT only if the addr
scope is link.

Vladimir Zapolskiy reports:
Commit a7259df767 ("memblock: make memblock_find_in_range method
private") invokes a kernel panic while running kmemleak on OF platforms
with nomaped regions:
Unable to handle kernel paging request at virtual address fff000021e00000
[...]
scan_block+0x64/0x170
scan_gray_list+0xe8/0x17c
kmemleak_scan+0x270/0x514
kmemleak_write+0x34c/0x4ac
The memory allocated from memblock is registered with kmemleak, but if
it is marked MEMBLOCK_NOMAP it won't have linear map entries so an
attempt to scan such areas will fault.
Ideally, memblock_mark_nomap() would inform kmemleak to ignore
MEMBLOCK_NOMAP memory, but it can be called before kmemleak interfaces
operating on physical addresses can use __va() conversion.
Make sure that functions that mark allocated memory as MEMBLOCK_NOMAP
take care of informing kmemleak to ignore such memory.

Pull ucounts fixes from Eric Biederman:
"There has been one very hard to track down bug in the ucount code that
we have been tracking since roughly v5.14 was released. Alex managed
to find a reliable reproducer a few days ago and then I was able to
instrument the code and figure out what the issue was.
It turns out the sigqueue_alloc single atomic operation optimization
did not play nicely with ucounts multiple level rlimits. It turned out
that either sigqueue_alloc or sigqueue_free could be operating on
multiple levels and trigger the conditions for the optimization on
more than one level at the same time.
To deal with that situation I have introduced inc_rlimit_get_ucounts
and dec_rlimit_put_ucounts that just focuses on the optimization and
the rlimit and ucount changes.
While looking into the big bug I found I couple of other little issues
so I am including those fixes here as well.
When I have time I would very much like to dig into process ownership
of the shared signal queue and see if we could pick a single owner for
the entire queue so that all of the rlimits can count to that owner.
That should entirely remove the need to call get_ucounts and
put_ucounts in sigqueue_alloc and sigqueue_free. It is difficult
because Linux unlike POSIX supports setuid that works on a single
thread"

Merge tag 'powerpc-5.15-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
- Fix a bug exposed by a previous fix, where running guests with
certain SMT topologies could crash the host on Power8.
- Fix atomic sleep warnings when re-onlining CPUs, when PREEMPT is
enabled.
Thanks to Nathan Lynch, Srikar Dronamraju, and Valentin Schneider.

AX88796C SPI Ethernet Adapter
This is a driver for AX88796C Ethernet Adapter connected in SPI mode as
found on ARTIK5 evaluation board. The driver has been ported from a
v3.10.9 vendor kernel for ARTIK5 board.

ASIX AX88796[1] is a versatile ethernet adapter chip, that can be
connected to a CPU with a 8/16-bit bus or with an SPI. This driver
supports SPI connection.
The driver has been ported from the vendor kernel for ARTIK5[2]
boards. Several changes were made to adapt it to the current kernel
which include:
+ updated DT configuration,
+ clock configuration moved to DT,
+ new timer, ethtool and gpio APIs,
+ dev_* instead of pr_* and custom printk() wrappers,
+ removed awkward vendor power managemtn.
+ introduced ethtool tunable to control SPI compression

The other ax88796 driver is for NE2000 compatible AX88796L chip. These
chips are not compatible. Hence, two separate drivers are required.

enetc: trivial PTP one-step TX timestamping cleanups
These are two cleanup patches for some inconsistencies
I noticed in the driver's TX ring cleanup function.

The code checks whether the skb had one-step TX timestamping enabled, in
order to schedule the work item for emptying the priv->tx_skbs queue.
That code checks for "tx_swbd->skb" directly, when we already had a skb
retrieved using enetc_tx_swbd_get_skb(tx_swbd) - a TX software BD can
also hold an XDP_TX packet or an XDP frame. But since the direct tx_swbd
dereference is in an "if" block guarded by the non-NULL quality of
"skb", accessing "tx_swbd->skb" directly is not wrong, just confusing.
Just use the local variable named "skb".

The "priv" variable is needed in the "check_writeback" scope since
commit d398231219 ("enetc: add hardware timestamping support").
Since commit 7294380c52 ("enetc: support PTP Sync packet one-step
timestamping"), we also need "priv" in the larger function scope.
So the local variable from the "if" block scope is not needed, and
actually shadows the other one. Delete it.

Submitting AP probe/null during suspend can cause unexpected
disconnect on resume because of timeout waiting for ack status:
wlan0: Failed to send nullfunc to AP 11:22:33:44:55:66 after 500ms, disconnecting
This is especially the case when we enter suspend when a scan is
ongoing, indeed, scan is cancelled from __ieee80211_suspend, leading
to a corresponding (aborted) scan complete event, which in turn causes
the submission of an immediate monitor null frame (restart_sta_timer).
The corresponding packet or ack will not be processed before resuming,
causing a timeout & disconnect on resume.
Delay the AP probing when suspending/suspended.
