USB: changes for v5.9 merge window
CDNS3 got several improvements, most of which are non-critical fixes.
DWC3 has a reset fix for the meson platform, while dwc2 has
improvements for role switch on STM32MP15 SoCs.
Apart from these, we have the usual set of non-critical fixes all over

Currently, maximum physical memory allowed is equal to -PAGE_OFFSET.
That's why we remove any memory blocks spanning beyond that size. However,
it is done only for memblock containing linux kernel which will not work
if there are multiple memblocks.
Process all memory blocks to figure out how much memory needs to be removed
and remove at the end instead of updating the memblock list in place.

This patch fixed 2 issues with the usage of skb_cow in LAPB drivers
"lapbether" and "hdlc_x25":
1) After skb_cow fails, kfree_skb should be called to drop a reference
to the skb. But in both drivers, kfree_skb is not called.
2) skb_cow should be called before skb_push so that is can ensure the
safety of skb_push. But in "lapbether", it is incorrectly called after
skb_push.
More details about these 2 issues:
1) The behavior of calling kfree_skb on failure is also the behavior of
netif_rx, which is called by this function with "return netif_rx(skb);".
So this function should follow this behavior, too.
2) In "lapbether", skb_cow is called after skb_push. This results in 2
logical issues:
a) skb_push is not protected by skb_cow;
b) An extra headroom of 1 byte is ensured after skb_push. This extra
headroom has no use in this function. It also has no use in the
upper-layer function that this function passes the skb to
(x25_lapb_receive_frame in net/x25/x25_dev.c).
So logically skb_cow should instead be called before skb_push.

from the memblock size of the memblock containing kernel. This will work
until that memblock spans the entire memory. However, it will be set to
a wrong value if there are multiple memblocks defined in kernel
(e.g. with efi runtime services).
Set the the maximum value to the pfn calculated from dram size.

We have to detach sock from socket in qrtr_release(),
otherwise skb->sk may still reference to this socket
when the skb is released in tun->queue, particularly
sk->sk_wq still points to &sock->wq, which leads to
a UAF.

important regressions fixed.

iwlwifi
* fix a regression which broke support for some Killer Wireless-AC 1550 cards

There's a potential race in xennet_remove(); this is what the driver is
doing upon unregistering a network device:
1. state = read bus state
2. if state is not "Closed":
3. request to set state to "Closing"
4. wait for state to be set to "Closing"
5. request to set state to "Closed"
6. wait for state to be set to "Closed"
If the state changes to "Closed" immediately after step 1 we are stuck
forever in step 4, because the state will never go back from "Closed" to
"Closing".
Make sure to check also for state == "Closed" in step 4 to prevent the
deadlock.
Also add a 5 sec timeout any time we wait for the bus state to change,
to avoid getting stuck forever in wait_event().

I noticed that touching linux/rhashtable.h causes lib/vsprintf.c to
be rebuilt. This dependency came through a bogus inclusion in the
file net/flow_offload.h. This patch moves it to the right place.
This patch also removes a lingering rhashtable inclusion in cls_api
created by the same commit.
