Shutemovkirill.shutemov@linux.intel.com2023-03-15T11:31:33+00:00urn:sha1:23baf831a32c04f9a968812511540b1b3e648bf5
MAX_ORDER currently defined as number of orders page allocator supports:
user can ask buddy allocator for page order between 0 and MAX_ORDER-1.
This definition is counter-intuitive and lead to number of bugs all over
the kernel.
Change the definition of MAX_ORDER to be inclusive: the range of orders
user can ask from buddy allocator is 0..MAX_ORDER now.
