[PATCH 0/1] MR6918: ntdll: Implement NtGetCurrentProcessorNumber for macOS on x86_64.

[Marc-Aurel Zent (＠mzent)]

Taken and slightly adapted from https://github.com/apple-oss-distributions/xnu/blob/8d741a5de7ff4191bf97d57b... .

The arm and arm64 implementations are not stable across kernel releases (yet). This works as expected under Rosetta 2 as well.
