[PATCH] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHM
Remove VM_LOCKED before remap_pfn range from device drivers and get rid of
VM_SHM.
remap_pfn_range() already sets VM_IO. There is no need to set VM_SHM since
it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not
place pages on the LRU. The pages are therefore never subject to swap
anyways. Remove all the vm_flags settings before calling remap_pfn_range.
After removing all the vm_flag settings no use of VM_SHM is left. Drop it.
