AFAICS the last uses of directly 'making' kernel PGDs was removed 7 years ago:
8b78c21d72d9: ("x86, 64bit, mm: hibernate use generic mapping_init")
Where the explicit PGD walking loop was replaced with kernel_ident_mapping_init()
calls. This was then (unnecessarily) carried over through the 5-level paging conversion.
Also clean up the 'level' comments a bit, to convey the original, meanwhile somewhat
bit-rotten notion, that these are empty comment blocks with no methods to handle any
of the levels except the PTE level.

to use CYC2NS_SCALE_FACTOR:
53d517cdbaac: ("x86: scale cyc_2_nsec according to CPU frequency")
The current TSC code uses the 'struct cyc2ns_data' scaling abstraction,
the old fixed scaling approach is long gone.
This cleanup also removes the 'arbitralrily' typo from the comment,
so win-win. ;-)

Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the
KSZ9031 PHY") the networking is broken on keystone-k2g-evm board.
The above board have phy-mode = "rgmii-id" and it is worked before because
KSZ9031 PHY started with default RGMII internal delays configuration (TX
off, RX on 1.2 ns) and MAC provided TX delay by default.
After above commit, the KSZ9031 PHY starts handling phy mode properly and
enables both RX and TX delays, as result networking is become broken.
Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous
behavior.

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.

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().

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Fix build warning in k3_ringacc_ring_cfg():
smatch warnings:
drivers/soc/ti/k3-ringacc.c:562 k3_ringacc_ring_cfg() warn: variable dereferenced before check 'ring' (see line 559)
557 int k3_ringacc_ring_cfg(struct k3_ring *ring, struct k3_ring_cfg *cfg)
558 {
@559 struct k3_ringacc *ringacc = ring->parent;
^^^^^^^^^^^^
Dereference.
560 int ret = 0;
561
@562 if (!ring || !cfg)
^^^^
Check too late. Delete it?

We only request ring pairs via K3 DMA driver, switch to use the new
k3_ringacc_request_rings_pair() to simplify the code.

Add new API k3_ringacc_request_rings_pair() to request pair of rings at
once, as in the most cases Rings are used with DMA channels, which need to
request pair of rings - one to feed DMA with descriptors (TX/RX FDQ) and
one to receive completions (RX/TX CQ). This will allow to simplify Ringacc
API users.

Pull xtensa csum regression fix from Al Viro:
"Max Filippov caught a breakage introduced in xtensa this cycle
by the csum_and_copy_..._user() series.
Cut'n'paste from the wrong source - the check that belongs
in csum_and_copy_to_user() ended up both there and in
csum_and_copy_from_user()"
