The Allwinner D1, T113 provide two CAN controllers that are variants
of the R40 controller.
I have tested support for these controllers on two boards:
- A Lichee Panel RV 86 Panel running a D1 chip
- A Mango Pi MQ Dual running a T113-s3 chip
Both of these fully support both CAN controllers.

net: stmmac: Increase clk_ptp_ref rate
This series aims to increase the clk_ptp_ref rate to get the best
possible PTP timestamping resolution possible. Some modified disclosure
about my development/testing process from the RFC/RFT v1 follows.
Disclosure: I don't know much about PTP beyond what you can google in an
afternoon, don't have access to documentation about the stmmac IP,
and have only tested that (based on code comments and git commit
history) the programming of the subsecond register (and the clock rate)
makes more sense with these changes. Qualcomm has tested a similar
change offlist, verifying PTP more formally as I understand it.
The last version was an RFC/RFT, but I didn't get a lot of confirmation
that doing patch 3 in that series (essentially setting clk_ptp_ref to
whatever its max value is) for the whole stmmac ecosystem was a safe
idea. So I am erring on the side of caution and doing this for the
Qualcomm platform only. See v1 for an approach that would apply to
all stmmac platform drivers with clk_ptp_ref.

Qualcomm clocks can set their frequency to a variety of levels
generally. Let's use the max for clk_ptp_ref to ensure the best
timestamping resolution possible.
Without this, the default value of the clock is used. For sa8775p-ride
this is 19.2 MHz, far less than the 230.4 MHz possible.

TLS resets the protocol operations, so the read_sock() callback might
be changed, too.
In this case using sock->ops->readsock() in tls_strp_read_copyin() will
enter an infinite recursion if the read_sock() callback is calling
tls_rx_rec_wait() which will call into sock->ops->readsock() via
tls_strp_read_copyin().
But as tls_strp_read_copyin() is supposed to produce data from the
consumed socket and that socket is always a TCP socket we can call
tcp_read_sock() directly without having to deal with callbacks.

Binutils 2.41 enables linker relaxation by default, but the kernel

As an alternative, we could add linker relaxation support in the kernel
module loader. But it is relatively large complexity that may or may not
bring a similar gain, and we don't really want to include this linker

This is a port of commit 4fe4a6374c ("MIPS: Only fiddle with
CHECKFLAGS if `need-compiler'") to LoongArch.
We have originally guarded fiddling with CHECKFLAGS in our arch Makefile
by checking for the CONFIG_LOONGARCH variable, not set for targets such
as `distclean', etc. that neither include `.config' nor use the compiler.
Starting from commit 805b2e1d42 ("kbuild: include Makefile.compiler
only when compiler is needed") we have had a generic `need-compiler'
variable explicitly telling us if the compiler will be used and thus its
capabilities need to be checked and expressed in the form of compilation
flags. If this variable is not set, then `make' functions such as
`cc-option' are undefined, causing all kinds of weirdness to happen if
we expect specific results to be returned.
It doesn't cause problems on LoongArch now. But as a guard we replace
the check for CONFIG_LOONGARCH with one for `need-compiler' instead, so
as to prevent the compiler from being ever called for CHECKFLAGS when
not needed.

The condition to fetch sense data was supposed to be:
ATA_SENSE set AND either
1) Command was NCQ and ATA_DFLAG_CDL_ENABLED flag set (flag
ATA_DFLAG_CDL_ENABLED will only be set if the Successful NCQ command
sense data supported bit is set); or
2) Command was non-NCQ and regular sense data reporting is enabled.
However the check in 2) accidentally had the negation at the wrong place,
causing it to try to fetch sense data if it was a non-NCQ command _or_
if regular sense data reporting was _not_ enabled.
Fix this by removing the extra parentheses that should not be there,
such that only the correct return (ata_is_ncq()) is negated.

bpf: Support new insns from cpu v4
In previous discussion ([1]), it is agreed that we should introduce
cpu version 4 (llvm flag -mcpu=v4) which contains some instructions
which can simplify code, make code easier to understand, fix the
existing problem, or simply for feature completeness. More specifically,
the following new insns are proposed:
. sign extended load
. sign extended mov
. bswap
. signed div/mod
. ja with 32-bit offset
This patch set added kernel support for insns proposed in [1] except
BPF_ST which already has full kernel support. Beside the above proposed
insns, LLVM will generate BPF_ST insn as well under -mcpu=v4.
The llvm patch ([2]) has been merged into llvm-project 'main' branch.
The patchset implements interpreter, jit and verifier support for these new
insns.
For this patch set, I tested cpu v2/v3/v4 and the selftests are all passed.
I also tested selftests introduced in this patch set with additional changes
beside normal jit testing (bpf_jit_enable = 1 and bpf_jit_harden = 0)
- bpf_jit_enable = 0
- bpf_jit_enable = 1 and bpf_jit_harden = 1
and both testing passed.

[2] https://reviews.llvm.org/D144829
Changelogs:
v4 -> v5:
. for v4, patch 8/17 missed in mailing list and patchwork, so resend.
. rebase on top of master
v3 -> v4:
. some minor asm syntax adjustment based on llvm change.
. add clang version and target arch guard for new tests
so they can still compile with old llvm compilers.
. some changes to the bpf doc.
v2 -> v3:
. add missed disasm change from v2.
. handle signed load of ctx fields properly.
. fix some interpreter sdiv/smod error when bpf_jit_enable = 0.
. fix some verifier range bounding errors.
. add more C tests.
RFCv1 -> v2:
. add more verifier supports for signed extend load and mov insns.
. rename some insn names to be more consistent with intel practice.
. add cpuv4 test runner for test progs.
. add more unit and C tests.
. add documentation.

Add unit tests for new ldsx insns. The test includes sign-extension
with a single value or with a value range.
If cpuv4 is not supported due to
(1) older compiler, e.g., less than clang version 18, or
(2) test runner test_progs and test_progs-no_alu32 which tests
cpu v2 and v3, or
(3) non-x86_64 arch not supporting new insns in jit yet,
a dummy program is added with below output:
#318/1 verifier_ldsx/cpuv4 is not supported by compiler or jit, use a dummy test:OK
#318 verifier_ldsx:OK
to indicate the test passed with a dummy test instead of actually
testing cpuv4. I am using a dummy prog to avoid changing the
verifier testing infrastructure. Once clang 18 is widely available
and other architectures support cpuv4, at least for CI run,
the dummy program can be removed.
