The patch titled Subject: mm/vmalloc: separate put pages and flush VM flags has been removed from the -mm tree. Its filename was mm-vmalloc-separate-put-pages-and-flush-vm-flags.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------ From: Rick Edgecombe rick.p.edgecombe@intel.com Subject: mm/vmalloc: separate put pages and flush VM flags

When VM_MAP_PUT_PAGES was added, it was defined with the same value as VM_FLUSH_RESET_PERMS. This doesn't seem like it will cause any big functional problems other than some excess flushing for VM_MAP_PUT_PAGES allocations.

Redefine VM_MAP_PUT_PAGES to have its own value. Also, rearrange things so flags are less likely to be missed in the future.
