- Support for LoongArch has been merged upstream. This allows to drop
  the loong64 specific kernel patches.
- Fixes [1] an issue encountered with when generating the
  SOCK_TXREHASH_DEFAULT constant from linux/socket.h on 5.18
- Contains a fix [2] to provide SYS_MEMFD_SECRET on linux/riscv64 as
  well, The underlying syscall was already available in earlier kernel
  versions. Also see golang/go#51547.

bc2c85ada1 unix: update openbsd Statfs_t fields 
This changes some fields of openbsd Statfs_t from arrays of int8
to arrays of byte. This makes the types of those fields correspond to
the types used on most other BSD systems (Darwin, FreeBSD, NetBSD),
and simplifies the conversion to Go string.

Similar changes: CL 359674, CL 259903, CL 74331.

Note that while this patches mkpost.go, the end result is obtained by
manual editing of ztypes_openbsd_*.go files. The reasons for this are:

1. automatic regeneration (tried on openbsd 6.9 / amd64) brings in way
   too many changes (5 files changed, 193 insertions, 45 deletions).

2. I could not figure out how to run openbsd on non-amd64.

Nevertheless, this change is sufficient, meaning if someone will
actually end up regenerating these (see e.g. CL 347649) after this
commit is merged, the fields will still be kept as arrays of byte.

dcacdad474 unix: use ByteSliceFromString in (*Ifreq).Name 
CL 340370 introduced (*Ifreq).Name method which scans the Ifrn field
for \0 twice -- first explicitly, when by calling BytePtrToString.

It seems more straightforward to use ByteSliceToString instead. The
differences are:
 - simpler code;
 - no double scanning for \0;
 - in case there is no \0 in the Ifrn (unlikely), the full string
   (rather than an empty string) is now returned.

With the last item in mind, the test case with no \0 as input that
expects empty output fails, so drop it. Alternatively, we could test
that it returns the full string, but it will be essentially testing
ByteSliceToString, which is not the point.

988cb79eb6 execabs: add legacy "//+build" constraints 
Go releases before Go 1.17 are no longer supported, and Go 1.17
supports the newer "//go:build" syntax, so the older "//+build"
variation is no longer required by Go's support policy. However, the
x/sys module is very low-level and empirically some users are still on
unsupported Go releases, so there is little harm in adding the older
variations.

33da011f77 unix: check correct group in Faccessat 
The Faccessat call checks the user, group, or other permission bits of a
file to see if the calling process can access it. The test to see if the
group permissions should be used was made with the wrong group id, using
the process's group id rather than the file's group id. Fix this to use
the correct group id.

This change only affects Linux versions prior to 5.8. Linux 5.8 added
the faccessat2 system call, which we use in preference to the internal
implementation.

No test since we cannot easily change file permissions when not running
as root and the test is meaningless if running as root.

For golang/go#52313

530d0810a4 unix: add utimensat libc wrapper on darwin 
Direct syscalls are no longer supported on darwin (CL 250437), so
utimensat can be implemented as a wrapper around the libc function.
The utimensat function was added in macOS 10.13 and Go 1.17 dropped
support for macOS 10.12.

This also allows to drop the fallback to setattrlistTimes which was
used to set timestamps with nanosecond resolution before utimensat could
be used, see golang/go#22528 and CL 74952.
