The quilt patch titled Subject: lib/test_meminit: allocate pages up to order MAX_ORDER has been removed from the -mm tree. Its filename was lib-test_meminit-allocate-pages-up-to-order-max_order.patch
This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
------------------------------------------------------ From: Andrew Donnellan ajd@linux.ibm.com Subject: lib/test_meminit: allocate pages up to order MAX_ORDER Date: Fri, 14 Jul 2023 11:52:38 +1000
test_pages() tests the page allocator by calling alloc_pages() with different orders up to order 10.
However, different architectures and platforms support different maximum contiguous allocation sizes. The default maximum allocation order (MAX_ORDER) is 10, but architectures can use CONFIG_ARCH_FORCE_MAX_ORDER to override this. On platforms where this is less than 10, test_meminit() will blow up with a WARN(). This is expected, so let's not do that.
Replace the hardcoded "10" with the MAX_ORDER macro so that we test allocations up to the expected platform limit.
