Merge tag 'nolibc.2023.02.06a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
Pull nolibc updates from Paul McKenney:
- Add s390 support
- Add support for the ARM Thumb1 instruction set
- Fix O_* flags definitions for open() and fcntl()
- Make errno a weak symbol instead of a static variable
- Export environ as a weak symbol
- Export _auxv as a weak symbol for auxilliary vector retrieval
- Implement getauxval() and getpagesize()
- Further improve self tests, including permitting userland testing of
the nolibc library
