lib/test_meminit: Allocate pages up to order MAX_ORDER
PATCH 1/1 lib/test_meminit: Allocate pages up to order MAX_ORDER
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.
