mm: remove mmu_gathers storage from remaining architectures

2022-03-22T22:57:04Z

Originally the mmu_gathers were removed in commit 1c3951769621 ("mm: now that all old mmu_gather code is gone, remove the storage"). However, the openrisc and hexagon architecture were merged around the same time and mmu_gathers was not removed. This patch removes them from openrisc, hexagon and nds32: Noticed while cleaning this warning: arch/openrisc/mm/init.c:41:1: warning: symbol 'mmu_gathers' was not declared. Should it be static?

mm: move mem_init_print_info() into mm_init()

2021-04-30T18:20:42Z

mem_init_print_info() is called in mem_init() on each architecture, and pass NULL argument, so using void argument and move it into mm_init().

mm: free_area_init: use maximal zone PFNs rather than zone sizes

2020-06-04T03:09:43Z

Currently, architectures that use free_area_init() to initialize memory map and node and zone structures need to calculate zone and hole sizes. We can use free_area_init_nodes() instead and let it detect the zone boundaries while the architectures will only have to supply the possible limits for the zones.

hexagon: drop empty and unused free_initrd_mem

2019-09-26T00:51:42Z

hexagon never reserves or initializes initrd and the only mention of it is the empty free_initrd_mem() function. As we have a generic implementation of free_initrd_mem(), there is no need to define an empty stub for the hexagon implementation and it can be dropped.
