arm/asm/tlb.h: Fix build error implicit func declaration
Building on arm 32 with LPAE enabled we don't include asm-generic/tlb.h, where we have tlb_flush_remove_tables_local and tlb_flush_remove_tables defined. The build fails with: mm/memory.c: In function ‘tlb_remove_table_smp_sync’: mm/memory.c:339:2: error: implicit declaration of function ‘tlb_flush_remove_tables_local’; did you mean ‘tlb_remove_table’? [-Werror=implicit-function-declaration] ... This bug got introduced in: 2ff6ddf19c0e ("x86/mm/tlb: Leave lazy TLB mode at page table free time") To fix this issue we define them in arm 32's specific asm/tlb.h file as well.
