Its filename is x86-numa-numa_addremove_cpu-make-cpu-parameter-unsigned.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/x86-numa-numa_addremove_cpu-make-cpu-parameter-unsigned.patch This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: "Mike Rapoport (Microsoft)" 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.
