The patch titled Subject: nios2: drop definition of PTE_ORDER has been added to the -mm mm-unstable branch. Its filename is nios2-drop-definition-of-pte_order.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/nios2-drop-definition-of-pte_order.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 <rppt@xxxxxxxxxxxxx> Subject: nios2: drop definition of PTE_ORDER Date: Sun, 3 Jul 2022 17:11:56 +0300 This is the order of the page table allocation, not the order of a PTE. Since its always hardwired to 0, simply drop it.
