sparc/mm/: possible cleanups
This patch contains the following possible cleanups:
- make the following needlessly global code static:
- fault.c: force_user_fault()
- init.c: calc_max_low_pfn()
- init.c: pgt_cache_water[]
- init.c: map_high_region()
- srmmu.c: hwbug_bitmask
- srmmu.c: srmmu_swapper_pg_dir
- srmmu.c: srmmu_context_table
- srmmu.c: is_hypersparc
- srmmu.c: srmmu_cache_pagetables
- srmmu.c: srmmu_nocache_size
- srmmu.c: srmmu_nocache_end
- srmmu.c: srmmu_get_nocache()
- srmmu.c: srmmu_free_nocache()
- srmmu.c: srmmu_early_allocate_ptable_skeleton()
- srmmu.c: srmmu_nocache_calcsize()
- srmmu.c: srmmu_nocache_init()
- srmmu.c: srmmu_alloc_thread_info()
- srmmu.c: early_pgtable_allocfail()
- srmmu.c: srmmu_early_allocate_ptable_skeleton()
- srmmu.c: srmmu_allocate_ptable_skeleton()
- srmmu.c: srmmu_inherit_prom_mappings()
- sunami.S: tsunami_copy_1page
- remove the following unused code:
- init.c: struct sparc_aliases
