Willy, Thomas
This is the revision of our 'tools/nolibc: add a new syscall helper' series [1].
It mainly applies the core part of suggestions from Thomas (Many thanks) and cleans up the multiple whitespaces issues reported by scripts/checkpatch.pl.
Changes from v4 --> v5:
* tools/nolibc: sys.h: add a syscall return helper tools/nolibc: unistd.h: apply __sysret() helper tools/nolibc: sys.h: apply __sysret() helper tools/nolibc: unistd.h: reorder the syscall macros tools/nolibc: __sysret: support syscalls who return a pointer selftests/nolibc: add EXPECT_PTREQ, EXPECT_PTRNE and EXPECT_PTRER selftests/nolibc: add sbrk_0 to test current brk getting
The same to original v4 series, no code change.
* tools/nolibc: string.h: clean up multiple whitespaces with tab tools/nolibc: arch-*.h: clean up multiple whitespaces tools/nolibc: arch-loongarch.h: shrink with SYSCALL_CLOBBERLIST tools/nolibc: arch-mips.h: shrink with SYSCALL_CLOBBERLIST
Clean up the multiple whitespaces issues reported by scripts/checkpatch.pl, prepare for the coming mips my_syscall6()
This cleanup is also required by another new arch shrink patchset.
In v4, we didn't touch multiple whitespaces, because the changes are huge, but it is really important to do this before being always 'complained' by scripts/checkpatch.pl in the future.
* tools/nolibc: add missing my_syscall6() for mips
Use tab instead of multiple whitespaces, let scripts/checkpatch.pl happy, also apply SYSCALL_CLOBBERLIST
* tools/nolibc: clean up mmap() support
Include <linux/mman.h> and remove more macros from nolibc side.
The return type of sys_mmap() is reserved as before, not changed currently.
* selftests/nolibc: add mmap and munmap test cases
Applies some suggestions from Thomas,
- Rebase length and offset on page_size and file_size
- make sure the last offset argument is not always zero to test my_syscall6()
- easier the for loop with NULL check
- use /proc/1/exe and /proc/self/exe for run, run-user and libc-test
but still reserve the old init files to align our another attempt to remove the unnecessary dependency on procfs (this is important to let developers happy to do all-architectures-test, the accumulated time cost and wait is really appreciable, it is really a pain for me to do repeated all-architectures-test for the new 'minimal' kernel config patchset [2], a v2 is ready for it).
