docs: gdbmacros: print newest record @head_id points to the newest record, but the printing loop exits when it increments to this value (before printing). Exit the printing loop after the newest record has been printed. The python-based function in scripts/gdb/linux/dmesg.py already does this correctly.

mm, treewide: introduce NR_PAGE_ORDERS [ Upstream commit fd37721803c6e73619108f76ad2e12a9aa5fafaf ] NR_PAGE_ORDERS defines the number of page orders supported by the page allocator, ranging from 0 to MAX_ORDER, MAX_ORDER + 1 in total. NR_PAGE_ORDERS assists in defining arrays of page orders and allows for more natural iteration over them.
