Pratyush Yadav (Google) 8fd2f26fa2 kho: fix order calculation for kho_unpreserve_pages() ... Commit 91e74fa8b1 ("kho: make sure preservations do not span multiple NUMA nodes") made sure preservations from kho_preserve_pages() do not span multiple NUMA nodes. If they do, the order is reduced and tried again. The same logic was not implemented for kho_unpreserve_pages(). This can result in unpreserve calculating a different order than preserve, and thus not actually unpreserving the pages. Fix this by moving the order calculation logic to __kho_preserve_pages_order() and use it from both preserve and unpreserve paths. Move __kho_unpreserve() down to avoid having a forward declaration. Its users are further down in the file anyway. Also, it results in grouping for all the page-level preservation and unpreservation functions. This unfortunately makes the diff hard to read, but the main change in __kho_unpreserve() is to call __kho_preserve_pages_order() instead of open-coding the order calculation.
