Subject[PATCH] xtensa: noMMU: fix vm_get_page_prot definition
Date
Don't define protection_map and don't use DECLARE_VM_GET_PAGE_PROT in
noMMU configs, because in that case the definition for vm_get_page_prot
is provided by the include/linux/mm.h

Fixes: 61ab8053710f ("xtensa/mm: enable ARCH_HAS_VM_GET_PAGE_PROT")
