Its filename is powerpc-book3s64-vmemmap-switch-radix-to-use-a-different-vmemmap-handling-function-fix.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/powerpc-book3s64-vmemmap-switch-radix-to-use-a-different-vmemmap-handling-function-fix.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: "Aneesh Kumar K.V" <aneesh.kumar@xxxxxxxxxxxxx> Subject: powerpc/mm: fix section mismatch warning Date: Thu, 27 Jul 2023 10:16:19 +0530 remove_pte_table is only called from remove_pmd_table which is marked __meminit. These functions are used only during memory hotplug and they also call functions marked __meminit. Mark remote_pte_table also with __meminit so that we can avoid the section mismatch warning below.
