The ISA DMA API is inconsistent between architectures, and while
powerpc implements most of what the others have, it does not provide
isa_virt_to_bus():
../drivers/net/ethernet/cirrus/cs89x0.c: In function ‘net_open’:
../drivers/net/ethernet/cirrus/cs89x0.c:897:20: error: implicit declaration of function ‘isa_virt_to_bus’ [-Werror=implicit-function-declaration]
(unsigned long)isa_virt_to_bus(lp->dma_buff));
../drivers/net/ethernet/cirrus/cs89x0.c:894:3: note: in expansion of macro ‘cs89_dbg’
cs89_dbg(1, debug, "%s: dma %lx %lx\n",
I tried a couple of approaches to handle this consistently across
all architectures, but as this driver is really only used on
ARM, I ended up taking the easy way out and just disable compile
testing on powerpc.

Setting DSA_MAX_PORTS caused DSA to call b53 callbacks (e.g.
b53_disable_port() during dsa_register_switch()) for invalid
(non-existent) ports. That made b53 modify unrelated registers and is
one of reasons for a broken BCM5301x support.

It isn't true that CPU port is always the last one. Switches BCM5301x
have 9 ports (port 6 being inactive) and they use port 5 as CPU by
default (depending on design some other may be CPU ports too).
A more reliable way of determining number of ports is to check for the
last set bit in the "enabled_ports" bitfield.
This fixes b53 internal state, it will allow providing accurate info to
the DSA and is required to fix BCM5301x support.

Florian noted that if mptcp_alloc_tx_skb() allocation fails
in __mptcp_push_pending(), we can end-up invoking
mptcp_push_release()/tcp_push() with a zero mss, causing
a divide by 0 error.
This change addresses the issue refactoring the skb allocation
code checking if skb collapsing will happen for sure and doing
the skb allocation only after such check. Skb allocation will
now happen only after the call to tcp_send_mss() which
correctly initializes mss_now.
As side bonuses we now fill the skb tx cache only when needed,
and this also clean-up a bit the output path.

I noticed that only port 0 worked on the RTL8366RB since we
started to use custom tags.
It turns out that the format of egress custom tags is actually
different from ingress custom tags. While the lower bits just
contain the port number in ingress tags, egress tags need to
indicate destination port by setting the bit for the
corresponding port.
It was working on port 0 because port 0 added 0x00 as port
number in the lower bits, and if you do this the packet appears
at all ports, including the intended port. Ooops.
Fix this and all ports work again. Use the define for shifting
the "type A" into place while we're at it.
Tested on the D-Link DIR-685 by sending traffic to each of
the ports in turn. It works.

In addition, increase timeout from usecs_to_jiffies(10000) to

timeout will be a single jiffies.
A single jiffies results actual timeout that can be any time between

The driver requires 64-bit doorbell writes to be atomic on 32-bit
architectures. So we redefined writeq as a new macro with spinlock
protection on 32-bit architectures. This created a new warning when
we added a new file in a recent patchset. writeq is defined on many
32-bit architectures to do the memory write non-atomically and it
generated a new macro redefined warning. This warning was fixed
incorrectly in the recent patch.
Fix this properly by adding a new bnxt_writeq() function that will
do the non-atomic write under spinlock on 32-bit systems. All callers
in the driver will now call bnxt_writeq() instead.

felt it was better to wait for the merge window to open; the patch is
marked with the usual -stable markings"

Pull idmapping documentation updates from Christian Brauner:
"The bulk of the idmapped work this cycle was adding support for
idmapped mounts to btrfs.
While this required the addition of a (simple) new vfs helper all the
work is going through David Sterba's btrfs tree. It was way simpler to
do it this way rather then forcing David to coordinate between his
btrfs and my tree. Plus I don't care who merges it as long as I feel I
can trust the maintainer and the btrfs folks were really fast and
helpful in reviewing this work.
As always, associated with the btrfs port for idmapped mounts is a new
fstests extension specifically concerned with btrfs ioctls (e.g.
subvolume creation, deletion etc.) on idmapped mounts which can be
found in the fstests repo as 5f8179ce8b00 ("btrfs: introduce btrfs
specific idmapped mounts tests").
Consequently, this cycle the idmapping pull is boring. It only
contains documentation updates, specifically about how idmappings and
idmapped mounts work"

Pull close_range() cleanup from Christian Brauner:
"This is a cleanup for close_range() which was sent as part of a bugfix
we did some time ago in commit 9b5b872215 ("file: fix close_range()
for unshare+cloexec").
We used to share more code between some helpers for close_range()
which made retrieving the maximum number of open fds before calling
into the helpers sensible. But with the introduction of
CLOSE_RANGE_CLOEXEC and the need to retrieve the number of maximum fds
once more for CLOSE_RANGE_CLOEXEC that stopped making sense. So the
code was in a dumb in-limbo state.
Fix this by simplifying the code a bit.
The original idea was to only fix the bug itself and make backporting
easy. And since the cleanup wasn't very pressing I left it in
linux-next for a very long time. I didn't pull the patches from the
list again back then which is why they don't have lore-links. So I'm
listing them below explicitly"
