     map vmalloc pages to userspace
 
Synopsis
| int remap_vmalloc_range ( | struct vm_area_struct * vma, | 
|  | void * addr, | 
|  | unsigned long pgoff ); | 
 
Arguments
- vma
- 
     vma to cover (map full range of vma)
     
- addr
- 
     vmalloc memory
     
- pgoff
- 
     number of pages into addr before first page to map
     
Returns
   0 for success, -Exxx on failure
   
   This function checks that addr is a valid vmalloc'ed area, and
   that it is big enough to cover the vma. Will return failure if
   that criteria isn't met.
