NAME

6       vm_iomap_memory - remap memory to userspace
7

SYNOPSIS

9       int vm_iomap_memory(struct vm_area_struct * vma, phys_addr_t start,
10                           unsigned long len);
11

ARGUMENTS

13       vma
14           user vma to map to
15
16       start
17           start of area
18
19       len
20           size of area
21

DESCRIPTION

23       This is a simplified io_remap_pfn_range for common driver use. The
24       driver just needs to give us the physical memory range to be mapped,
25       we'll figure out the rest from the vma information.
26
27       NOTE! Some drivers might want to tweak vma->vm_page_prot first to get
28       whatever write-combining details or similar.
