nommu: add new vmalloc_user() and remap_vmalloc_range() interfaces.
This builds on top of the earlier vmalloc_32_user() work introduced by b50731732f926d6c49fd0724616a7344c31cd5cf, as we now have places in the nommu allmodconfig that hit up against these missing APIs. As vmalloc_32_user() is already implemented, this is moved over to vmalloc_user() and simply made a wrapper. As all current nommu platforms are 32-bit addressable, there's no special casing we have to do for ZONE_DMA and things of that nature as per GFP_VMALLOC32. remap_vmalloc_range() needs to check VM_USERMAP in order to figure out whether we permit the remap or not, which means that we also have to rework the vmalloc_user() code to grovel for the VMA and set the flag.
