This PR adds support for newest stable linux to keystone driver.
In Linux 6.8, macro
MAX_ORDERis renamed toMAX_PAGE_ORDER.https://elixir.bootlin.com/linux/v6.8.8/source/include/linux/mmzone.h#L30
Compilation will fail in linux 6.8 because of this change.
To avoid this, I added preprocessor that changes the name depending on the kernel version.
This works correctly under Ubuntu 24.04 that uses kernel
6.8.0-31-generic.I also tested on real hardware, HiFive Unmatched.
Thanks.
