Since KVM isn't equipped to handle closure of vcpu fd from userspace(QEMU)
correctly, certain work arounds have to be employed to allow reuse of
vcpu array slot in KVM during cpu hot plug/unplug from guest. One such
proposed workaround is to park the vcpu fd in userspace durin
Currently, the macro IS_BRIDGE is not used any where.
This patch just removes it.

As the comment indicates, powernv_eeh_get_state() will inform EEH core to
delay 1 second. This means the delay doesn't happen when
powernv_eeh_get_state() returns.
This patch moves the delay subtraction just before msleep(), which is the
same logic in pseries_eeh_wait_state().

To retrieve the PCI slot state, EEH driver would set a timeout for that.
While current comment is not aligned to what the code does.
This patch fixes those comments according to the code.

struct pci_io_addr_range{} stores the information of pci resources. It
would be better to keep these related fields have the same type as in
struct resource{}.
This patch fixes the start/end/flags type in struct pci_io_addr_range{} to
have the same type as in struct resource{}.

Four patches to cleanup the EEH, in type, comment and logic.
Wei Yang (4):
powerpc/eeh: fix start/end/flags type in struct pci_io_addr_range{}
powerpc/eeh: fix comment for wait_state()
powerpc/eeh: fix powernv_eeh_wait_state delay logic
powerpc/eeh: remove unused macro IS_BRIDGE

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 a
Now we could use pci_scan_host_bridge() to scan
pci buses, provide powerpc specific pci_host_bridge_ops.

Pcibios_root_bridge_prepare() in powerpc is used
to set root bus speed. Rename it to
pcibios_set_root_bus_speed() for better readability.

This patch implements LED driver for PowerNV platform using the existing
generic LED class framework. It registers classdev structures for all
individual LEDs detected on the system through LED specific device tree
nodes. Device tree nodes specify what all kind of LEDs pre

This patch registers the following two new OPAL interfaces calls
for the platform LED subsystem. With the help of these new OPAL calls,
the kernel will be able to get or set the state of various individual
LEDs on the system at any given location code which is passed throu
The following series implements LED driver for PowerNV platform.

Hi Ludovic,
if you have a few minutes, could you please test this series? I'd like to
include it in 4.1. and because at91 is using the quirk infrastructure in
a more complex way,
