Commit "mm/slub: optimize alloc/free fastpath by removing preemption on/off"
has added access to percpu memory while the code is preemptible.
While those accesses are okay, this creates a huge amount of warnings from

Add some helpers to share the constraints of devices while attaching

At each attach, the constraints are calculated based on the following:

Since now kaslr can separately do randomization of physical and virtual
address, the physical address doesn't have to be
CONFIG_RANDOMIZE_BASE_MAX_OFFSET any more. At this time the identity
mapping only covers [0, 4G], so extend the upper limit of kernel physical
address randomization to 4G.
Currently kaslr only randomize physical address of kernel loading, then add the
delta
to virtual address of kernel text mapping. Because kernel virtual address can
only be
from __START_KERNEL_map to LOAD_PHYSICAL_ADDR+CONFIG_RANDOMIZE_BASE_MAX_OFFSET,
namely
[0x8000,
For kernel virtual address, need set LOAD_PHYSICAL_ADDR to be the default
offset if randomization failed. Because it will be used to check whether
a relocation handling need be done for x86_64 kaslr.

When process 32 bit relocation a local variable extended is defined
to calculate the physical address of relocs entry. However its data

relocation can only be handled when kernel is loaded below 2G,

On x86_64, in old kaslr implementaion only physical address of kernel

Currently, we use int type for bus number in
pci_create_root_bus(), pci_scan_root_bus() and
pci_scan_bus_legacy. Because PCI bus number
always <= 255, so we could change the bus number
argument type to u32, and combine PCI domain and
bus number in one. Also add a domain member in
pci_host_bridge
Pci_bus_add_devices() should not be placed in pci_scan_bus().
Now pci device will be added to driver core once its
creation. All things left in pci_bus_add_devices() are
driver attachment and other trivial sysfs things.
Pci_scan_bus() should be the function responsible for
scanning PCI devices,
v1->v2:
Split pci_host_bridge_list into a new patch, remove .phb_probe_mode
and rework powerpc .phb_of_scan_bus() for simpilicty suggested by

Now we could pass PCI domain combined with bus number
in u32 argu. Because in arm/arm64, PCI domain number
is assigned by pci_bus_assign_domain_nr(). So we leave
pci_scan_root_bus() and pci_create_root_bus() in arm/arm64
unchanged. A new function pci_host_assign_domain_nr()
will be introduced for
Now pci_scan_root_bus() is almost simliar 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.

Sometimes, we need to know the highest reserved
busnr for children bus. Because parent's
bus->busn_res could have padding in it.
This function return the max child busnr as
pci_scan_child_bus().

This is a patch for adding gpio control about enable/disable of buck.

This patch is relative to linux-next repository tag next-20150120.
Changes in V3:
- align with next-20150120.
- remove warn message.
Changes in V2:
- gpio name from gpio to gpios.
- add
Just like pci_scan_bus(), we also should rip out
pci_bus_add_devices() from pci_scan_root_bus().
Lots platforms first call pci_scan_root_bus(), but
after that, they call pci_bus_size_bridges() and
pci_bus_assign_resources(). Place pci_bus_add_devices()
in pci_scan_root_bus() hurts PCI scan logic.
From: Yijing Wang
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. We could also remove the pci bus
resource(dino_current_bus,255) and pci_bus_update_busn_res_end(),
Pcibios_root_bridge_prepare() in powerpc is used
to set root bus speed. Rename it to
pcibios_set_root_bus_speed() for better readability.

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.

Now we save the domain number in pci_host_bridge,
we could remove pci_bus_assign_domain_nr() and
clean the domain member in pci_bus.
