gpu: nvgpu: split address space for fixed allocs
Allow a special address space node to be split out from the
user adress space or fixed allocations. A debugfs node,
/d/<gpu>/separate_fixed_allocs
Controls this feature. To enable it:
# echo <SPLIT_ADDR> > /d/<gpu>/separate_fixed_allocs
Where <SPLIT_ADDR> is the address to do the split on in the
GVA address range. This will cause the split to be made in
all subsequent address space ranges that get created until it
is turned off. To turn this off just echo 0x0 into the same
debugfs node.
