Add support for (yet again) more RVA23U64 missing extensions. Add
support for Zcmop, Zca, Zcf, Zcd and Zcb extensions isa string parsing,
hwprobe and kvm support. Zce, Zcmt and Zcmp extensions have been left
out since they target microcontrollers/embedded CPUs and are not needed
by RVA23U64.
Since Zc* extensions states that C implies Zca, Zcf (if F and RV32), Zcd
(if D), this series modifies the way ISA string is parsed and now does
it in two phases. First one parses the string and the second one
validates it for the final ISA description.
This series is based on the Zimop one [1]. An additional fix [2] should
be applied to correctly test that series.

2.43.0
From: Mark Brown <broonie(a)kernel.org>
[ Upstream commit 907f33028871fa7c9a3db1efd467b78ef82cce20 ]
The standard library perror() function provides a convenient way to print
an error message based on the current errno but this doesn't play nicely
with KTAP output. Provide a helper which does an equivalent thing in a KTAP
compatible format.
nolibc doesn't have a strerror() and adding the table of strings required
doesn't seem like a good fit for what it's trying to do so when we're using
that only print the errno.

To verify IFS (In Field Scan [1]) driver functionality, add the following 6
test cases:
1. Verify that IFS sysfs entries are created after loading the IFS module
2. Check if loading an invalid IFS test image fails and loading a valid
one succeeds
3. Perform IFS scan test on each CPU using all the available image files
4. Perform IFS scan with first test image file on a random CPU for 3
rounds
5. Perform IFS ARRAY BIST(Board Integrated System Test) test on each CPU
6. Perform IFS ARRAY BIST test on a random CPU for 3 rounds
These are not exhaustive, but some minimal test runs to check various
parts of the driver. Some negative tests are also included.

2.43.0
From: Geliang Tang <tanggeliang(a)kylinos.cn>
This patchset uses post_socket_cb and post_connect_cb callbacks of struct
network_helper_opts to refactor do_test() in bpf_tcp_ca.c to move dctcp
test dedicated code out of do_test() into test_dctcp().
Patch 3 adds a new member in post_socket_opts and patch 4 adds a new
callback in network_helper_opts. I'm not sure if this is going too far.
Geliang Tang (4):
selftests/bpf: Use post_socket_cb in connect_to_fd_opts
selftests/bpf: Use start_server_addr in bpf_tcp_ca
selftests/bpf: Use connect_to_fd_opts in do_test in bpf_tcp_ca
