sparc32: do not include swap.h from pgtable_32.h
"memcg: export struct mem_cgroup" will add includes into linux/memcontrol.h which lead to further header dependency issues as reported by Guenter Roeck: In file included from include/linux/highmem.h:7:0, from include/linux/bio.h:23, from include/linux/writeback.h:192, from include/linux/memcontrol.h:30, from include/linux/swap.h:8, from ./arch/sparc/include/asm/pgtable_32.h:17, from ./arch/sparc/include/asm/pgtable.h:6, from arch/sparc/kernel/traps_32.c:23: include/linux/mm.h: In function 'is_vmalloc_addr': include/linux/mm.h:371:17: error: 'VMALLOC_START' undeclared (first use in this function) include/linux/mm.h:371:17: note: each undeclared identifier is reported only once for each function it appears in include/linux/mm.h:371:41: error: 'VMALLOC_END' undeclared (first use in this function) include/linux/mm.h: In function 'maybe_mkwrite': include/linux/mm.h:556:3: error: implicit declaration of function 'pte_mkwrite' The issue is that pgtable_32.h depends on swap.h to get swap_entry_t but that goes all the way down to linux/mm.h which wants to have VMALLOC_* which is defined later in pgtable_32.h, though. swap_entry_t is defined in include/mm_types.h so it should be sufficient to include this header without more dependencies.
