The patchset contains few changes to the vmalloc code, which are
leading to some performance gains and code simplification.

Also, it exports a number of pages, used by vmalloc(),
in /proc/meminfo.

Patch (1) removes some redundancy on __vunmap().
Patch (2) separates memory allocation and data initialization
  in alloc_vmap_area()
Patch (3) adds vmalloc counter to /proc/meminfo.

RFC->v1:
  - removed bogus empty lines (suggested by Matthew Wilcox)
  - made nr_vmalloc_pages static (suggested by Matthew Wilcox)
  - dropped patch 3 from RFC patchset, will post later with
  some other changes
  - dropped RFC

Roman Gushchin (3):
  mm: refactor __vunmap() to avoid duplicated call to find_vm_area()
  mm: separate memory allocation and actual work in alloc_vmap_area()
  mm: show number of vmalloc pages in /proc/meminfo
