b6f6a7aa68 smb3: add dynamic trace point for session setup key expired failures
There are cases where services need to remount (or change their
credentials files) when keys have expired, but it can be helpful
to have a dynamic trace point to make it easier to notify the
service to refresh the storage account key.

Here is sample output, one from mount with bad password, one
from a reconnect where the password has been changed or expired
and reconnect fails (requiring remount with new storage account key)

4c7be57f27 arm64: allow installing compressed image by default
On arm64 we build compressed images, but "make install" by default will
install the old non-compressed one.  To actually get the compressed
image install, you need to use "make zinstall", which is not the usual
way to install a kernel.

Which may not sound like much of an issue, but when you deal with
multiple architectures (and years of your fingers knowing the regular
"make install" incantation), this inconsistency is pretty annoying.

But as Will Deacon says:
 "Sadly, bootloaders being as top quality as you might expect, I don't
  think we're in a position to rely on decompressor support across the
  board. Our Image.gz is literally just that -- we don't have a built-in
  decompressor (nor do I think we want to rush into that again after the
  fun we had on arm32) and the recent EFI zboot support solves that
  problem for platforms using EFI.

  Changing the default 'install' target terrifies me. There are bound to
  be folks with embedded boards who've scripted this and we could really
  ruin their day if we quietly give them a compressed kernel that their
  bootloader doesn't know how to handle :/"

So make this conditional on a new "COMPRESSED_INSTALL" option.

342b2e395d io_uring/napi: use ktime in busy polling
It's more natural to use ktime/ns instead of keeping around usec,
especially since we're comparing it against user provided timers,
so convert napi busy poll internal handling to ktime. It's also nicer
since the type (ktime_t vs unsigned long) now tells the unit of measure.

Keep everything as ktime, which we convert to/from micro seconds for
IORING_[UN]REGISTER_NAPI. The net/ busy polling works seems to work with
usec, however it's not real usec as shift by 10 is used to get it from
nsecs, see busy_loop_current_time(), so it's easy to get truncated nsec
back and we get back better precision.

Note, we can further improve it later by removing the truncation and
maybe convincing net/ to use ktime/ns instead.

RISC-V: Provide the frequency of time CSR via hwprobe
The RISC-V architecture makes a real time counter CSR (via RDTIME
instruction) available for applications in U-mode but there is no
architected mechanism for an application to discover the frequency
the counter is running at. Some applications (e.g., DPDK) use the
time counter for basic performance analysis as well as fine grained
time-keeping.

Add support to the hwprobe system call to export the time CSR
frequency to code running in U-mode.

riscv: Extend sv39 linear mapping max size to 128G
This harmonizes all virtual addressing modes which can now all map
(PGDIR_SIZE * PTRS_PER_PGD) / 4 of physical memory.

The RISCV implementation of KASAN requires that the boundary between
shallow mappings are aligned on an 8G boundary. In this case we need
VMALLOC_START to be 8G aligned. So although we only need to move the
start of the linear mapping down by 4GiB to allow 128GiB to be mapped,
we actually move it down by 8GiB (creating a 4GiB hole between the
linear mapping and KASAN shadow space) to maintain the alignment
requirement.

riscv: Improve exception and system call latency
Many CPUs implement return address branch prediction as a stack. The
RISCV architecture refers to this as a return address stack (RAS). If
this gets corrupted then the CPU will mispredict at least one but
potentally many function returns.

There are two issues with the current RISCV exception code:

- We are using the alternate link stack (x5/t0) for the indirect branch
  which makes the hardware think this is a function return. This will
  corrupt the RAS.

- We modify the return address of handle_exception to point to
  ret_from_exception. This will also corrupt the RAS.

Testing the null system call latency before and after the patch:

Visionfive2 (StarFive JH7110 / U74)
baseline: 189.87 ns
patched:  176.76 ns

Lichee pi 4a (T-Head TH1520 / C910)
baseline: 666.58 ns
patched:  636.90 ns

Just over 7% on the U74 and just over 4% on the C910.

915d0741e0 i3c: master: svc: Improve DAA STOP handle code logic
The REQUEST_PROC_DAA command behaves differently from other commands.
Sometimes the hardware can auto emit STOP, but in other conditions, it
cannot.

Improves the code logic to better handle these situations.

Hardware can auto emit STOP only when the following conditions are met:
- The previous I3C device correctly returns a PID and ACKs an I3C address.
- A NACK is received when emitting 7E to try to get the next I3C device's
PID.

In all other cases, a manual STOP emission is needed.

The code is changed to emit STOP when break the while loop and 'return 0'
only when the hardware can auto emit STOP.

be90ae1ba1 i3c: mipi-i3c-hci: Fix number of DAT/DCT entries for HCI versions < 1.1
I was wrong about the TABLE_SIZE field description in the
commit 0676bfebf5 ("i3c: mipi-i3c-hci: Fix DAT/DCT entry sizes").

For the MIPI I3C HCI versions 1.0 and earlier the TABLE_SIZE field in
the registers DAT_SECTION_OFFSET and DCT_SECTION_OFFSET is indeed defined
in DWORDs and not number of entries like it is defined in later versions.

Where above fix allowed driver initialization to continue the wrongly
interpreted TABLE_SIZE field leads variables DAT_entries being twice and
DCT_entries four times as big as they really are.

That in turn leads clearing the DAT table over the boundary in the
dat_v1.c: hci_dat_v1_init().

So interprete the TABLE_SIZE field in DWORDs for HCI versions < 1.1 and
fix number of DAT/DCT entries accordingly.

9bc7501b0b i3c: master: svc: resend target address when get NACK
According to I3C Spec 1.1.1, 11-Jun-2021, section: 5.1.2.2.3:

If the Controller chooses to start an I3C Message with an I3C Dynamic
Address, then special provisions shall be made because that same I3C Target
may be initiating an IBI or a Controller Role Request. So, one of three
things may happen: (skip 1, 2)

3. The Addresses match and the RnW bits also match, and so neither
Controller nor Target will ACK since both are expecting the other side to
provide ACK. As a result, each side might think it had "won" arbitration,
but neither side would continue, as each would subsequently see that the
other did not provide ACK.
...
For either value of RnW: Due to the NACK, the Controller shall defer the
Private Write or Private Read, and should typically transmit the Target
						    ^^^^^^^^^^^^^^^^^^^
Address again after a Repeated START (i.e., the next one or any one prior
^^^^^^^^^^^^^
to a STOP in the Frame). Since the Address Header following a Repeated
START is not arbitrated, the Controller will always win (see Section
5.1.2.2.4).

Resend target address again if address is not 7E and controller get NACK.

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bpf and netfilter.

  A lot of networking people were at a conference last week, busy
  catching COVID, so relatively short PR.

  Current release - regressions:

   - tcp: process the 3rd ACK with sk_socket for TFO and MPTCP

  Current release - new code bugs:

   - l2tp: protect session IDR and tunnel session list with one lock,
     make sure the state is coherent to avoid a warning

   - eth: bnxt_en: update xdp_rxq_info in queue restart logic

   - eth: airoha: fix location of the MBI_RX_AGE_SEL_MASK field

  Previous releases - regressions:

   - xsk: require XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len,
     the field reuses previously un-validated pad

  Previous releases - always broken:

   - tap/tun: drop short frames to prevent crashes later in the stack

   - eth: ice: add a per-VF limit on number of FDIR filters

   - af_unix: disable MSG_OOB handling for sockets in sockmap/sockhash"

b485625078 sysctl: treewide: constify the ctl_table argument of proc_handlers
Summary
 - const qualify struct ctl_table args in proc_handlers:
   This is a prerequisite to moving the static ctl_table structs into .rodata
   data which will ensure that proc_handler function pointers cannot be
   modified.
