|
|
|
|
* nested atomic mappings with the fact that large page sizes and many
|
|
|
|
* processors chew up address space quickly. In a typical
|
|
|
|
* 64-processor, 64KB-page layout build, making KM_TYPE_NR one larger
|
|
|
|
* adds 4MB of required address-space. For now we leave KM_TYPE_NR
|
|
|
|
* set to depth 8.
