Its filename is x86-setup-call-hugetlb_bootmem_alloc-early.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/x86-setup-call-hugetlb_bootmem_alloc-early.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: Frank van der Linden Subject: x86/setup: call hugetlb_bootmem_alloc early Date: Thu, 6 Feb 2025 18:51:01 +0000 Call hugetlb_bootmem_allloc in an earlier spot in setup, after hugelb_cma_reserve. This will make vmemmap preinit of the sections covered by the allocated hugetlb pages possible.
