Introduce struct alloc_context to accumulate the numerous parameters passed between the alloc_pages* family of functions and get_page_from_freelist(). This excludes gfp_flags and alloc_info, which mutate too much along the way, and allocation order, which is conceptually different. The result is shorter function signatures, as well as overal code size and stack usage reductions. bloat-o-meter: add/remove: 0/0 grow/shrink: 1/2 up/down: 127/-310 (-183) function old new delta get_page_from_freelist 2525 2652 +127 __alloc_pages_direct_compact 329 283 -46 __alloc_pages_nodemask 2564 2300 -264 checkstack.pl: function old new __alloc_pages_nodemask 248 200 get_page_from_freelist 168 184 __alloc_pages_direct_compact 40 24 Signed-off-by: NVlastimil Babka <vbabka@suse.cz> Acked-by: NMichal Hocko <mhocko@suse.cz> Cc: Mel Gorman <mgorman@suse.de> Cc: Zhang Yanfei <zhangyanfei@cn.fujitsu.com> Cc: Minchan Kim <minchan@kernel.org> Cc: David Rientjes <rientjes@google.com> Cc: Rik van Riel <riel@redhat.com> Cc: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com> Cc: "Kirill A.
