From 290fa172d35194aebc42b0d7076942391bf9deef Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 26 Apr 2013 21:07:03 +0200 Subject: ldd3: get rid of deprecated VM_RESERVED vma flag commit 314e51b9 ("mm: kill vma flag VM_RESERVED and mm->reserved_vm counter") removed the VM_RESERVED vma flag since it lost original meaning. VM_RESERVED was used on many drivers' mmap function handler to avoid swap this memory area. The same semantic can be specified with VM_IO | VM_DONTDUMP flags but these are already set by remap_pfn_range() so they don't have to be set in drivers mmap function handlers.
