Subject: x86/numa: numa_{add,remove}_cpu: make cpu parameter unsigned
Date: Wed, 7 Aug 2024 09:41:00 +0300

CPU id cannot be negative.

Making it unsigned also aligns with declarations in
include/asm-generic/numa.h used by arm64 and riscv and allows sharing numa
emulation code with these architectures.
