mm: fix swapped Movable and Reclaimable in /proc/pagetypeinfo
Commit 016c13daa5c9 ("mm, page_alloc: use masks and shifts when converting GFP flags to migrate types") has swapped MIGRATE_MOVABLE and MIGRATE_RECLAIMABLE in the enum definition. However, migratetype_names wasn't updated to reflect that. As a result, the file /proc/pagetypeinfo shows the counts for Movable as Reclaimable and vice versa. Additionally, commit 0aaa29a56e4f ("mm, page_alloc: reserve pageblocks for high-order atomic allocations on demand") introduced MIGRATE_HIGHATOMIC, but did not add a letter to distinguish it into show_migration_types(), so it doesn't appear in the listing of free areas during page alloc failures or oom kills. This patch fixes both problems. The atomic reserves will show with a letter 'H' in the free areas listings.
