[PATCH bpf-next v2 0/4] selftest related fixes

[Vineet Gupta <vineet.gupta@linux.dev>]

Hi,

This is a set of fixes accumulated during BPF_GCC testing and an in-works
verifier enhancement series for 32-bit tracking.

Changes since v1:

 - 1/4: reworked. Instead of forcing BPF_STX with barrier_var(), select
   the expected message with #ifdef __BPF_FEATURE_ST, per Yonghong. The
   changelog now spells out the two tradeoffs: on a BPF_ST toolchain the
   test no longer reaches map_kptr_match_type(), and __BPF_FEATURE_ST
   means "can emit BPF_ST", not "will" - clang -mcpu=v4 -O0 still emits
   BPF_STX, so the #ifdef is only correct because selftests build at -O2.

 - 2/4: reword the comment above the error-summary walk. With
   --no-error-summary and no --json-summary the loop is skipped
   entirely, not just the printing, which the old wording obscured.
   [bpf-ci]

 - 4/4: the RV64 recipe in README.rst wraps the denylist in \" and
   relies on the guest's second parse of the init script to remove
   them, so %q broke it - the quotes reached test_progs and
   parse_test_list() split them into junk filters. Drop the
   backslashes so the host consumes the quotes, and correct the
   changelog, which wrongly claimed README.rst shows the command
   unquoted. [bpf-ci]

 - 3/4: unchanged.

Thx,
