If __get_user_pages() is faulting a significant number of hugetlb pages,
usually as the result of mmap(MAP_LOCKED), it can potentially allocate a

If the process has been oom killed, this will cause a lot of memory to

Now pci_bus_add_devices() has been ripped out
from pci_scan_root_bus(), we could use pci_scan_root_bus()
instead of pci_create_root_bus() + pci_scan_child_bus()
for simplicity.

There is no INT3401 in the acpi dump. Also no one registered IRQ 86.
So the request_irq failing.
It is not a problem, thi
Now pci_scan_root_bus() is almost similar to
pci_create_root_bus() + pci_scan_child_bus().
So we could use common pci_scan_root_bus() in
pci_common_init_dev() to scan pci busses.
tegra_pcie_scan_bus() is redundant, remove it.

This patch separate pci_host_bridge creation out
of pci_create_root_bus(), and try to make a generic
pci_host_bridge, then we could place generic PCI
infos like domain number in it. Also Ripping out
pci_host_bridge creation from pci_create_root_bus()
make code more better readability. Further more,
Mvebu_pcie_scan_bus() is not necessary, we could use
pci_common_init_dev() instead of pci_common_init(),
and pass the device pointer as the parent. Then
pci_scan_root_bus() will be called to scan the pci busses.
