/**
* Test specification for: test_map_buf
*
* Description: The VM unit shall be able to map a buffer of memory such that
* the GPU may access that memory.
*
* Test Type: Feature based
*
* Input: None
*
* Steps:
* - Initialize a VM with the following characteristics:
* - 64KB large page support enabled
* - Low hole size = 64MB
* - Address space size = 128GB
* - Kernel reserved space size = 4GB
* - Map a 4KB buffer into the VM
* - Check that the resulting GPU virtual address is aligned to 4KB
* - Unmap the buffer
* - Map a 64KB buffer into the VM
* - Check that the resulting GPU virtual address is aligned to 64KB
* - Unmap the buffer
* - Uninitialize the VM
*
* Output: Returns PASS if the steps above were executed successfully. FAIL
* otherwise.

* Steps:
* - Initialize a VM with the following characteristics:
* - 64KB large page support enabled
* - Low hole size = 64MB
* - Address space size = 128GB
* - Kernel reserved space size = 4GB
* - Map/unmap 10 4KB buffers using batch mode
