  syscalls: add back legacy __NR_nfsservctl macro (2024-08-06 08:57:02 +0200)

----------------------------------------------------------------
asm-generic fixes for 6.11, part 2

There are two more changes to the syscall.tbl conversion: the
'__NR_newfstat' in the previous bugfix was a mistake and gets reverted
now, after triple-checking that the contents are now back to what they
were on all architectures. The __NR_nfsservctl definition is not really
needed but came up in the same discussion as it had previously been
defined in uapi/asm-generic/unistd.h and tested for in user space.

TThere are a few more symbols that used to be defined in the old
unistd.h file, but that are never defined on any other architecture
using syscall.tbl format. These used to be needed inside of the kernel:

   __NR_syscalls
   __NR_arch_specific_syscall
   __NR3264_*

Searching for these on https://codesearch.debian.net/ shows a few packages
(rustc, golang, clamav, libseccomp, librsvg, strace) that duplicate all
the macros from asm/unistd.h, but nothing that actually uses the macros,
so I concluded that they are fine to omit after all.

----------------------------------------------------------------
Arnd Bergmann (2):
      syscalls: fix fstat() entry again
      syscalls: add back legacy __NR_nfsservctl macro
