conflicting, it will be temporarily blacklisted. The mmap_region()
function will retry other VMA candidates for a predefined number of
iterations.

call when a device context is initialized.

The idea of GMEM was originated from Weixi's PhD study with
Prof. Scott Rixner and Prof. Alan L. Cox at Rice University.

overlapped. In a test with Huawei's Ascend NPU card, the MADV_PREFETCH is
able to saturate the host-device bandwidth if the given VMA size is larger
than 16MB.

Furthermore, this allows an application user to issue memory hints that
bind with specific hNUMA nodes.
