arm64: convert unistd_32.h to syscall.tbl format
This is a straight conversion from the old asm/unistd32.h into the
format used by 32-bit arm and most other architectures, calling scripts
to generate the asm/unistd32.h header and a new asm/syscalls32.h headers.
I used a semi-automated text replacement method to do the conversion,
and then used 'vimdiff' to synchronize the whitespace and the (unused)
names of the non-compat syscalls with the arm version.
There are two differences between the generated syscalls names and the
old version:
- the old asm/unistd32.h contained only a __NR_sync_file_range2
entry, while the arm32 version also defines
__NR_arm_sync_file_range with the same number. I added this
duplicate back in asm/unistd32.h.
- __NR__sysctl was removed from the arm64 file a while ago, but
all the tables still contain it. This should probably get removed
everywhere but I added it here for consistency.
On top of that, the arm64 version does not contain any references to
the 32-bit OABI syscalls that are not supported by arm64. If we ever
want to share the file between arm32 and arm64, it would not be
hard to add support for both in one file.
