In function pci_get_subsys() there is a check:
/*
* pci_find_subsys() can be called on the ide_setup() path,
* super-early in boot. But the down_read() will enable local
* interrupts, which can cause some machines to crash. So here we
* detect and flag that situation and bail out early.
*/
if (unlikely(no_pci_devices()))
return NULL;
But there is no ide_setup() now, and no down_read() either, which
makes the check obsolete. So remove it.

In arch ia64, has following definition:
extern u8 numa_slit[MAX_NUMNODES * MAX_NUMNODES];
#define node_distance(from,to) (numa_slit[(from) * num_online_nodes() + (to)])
num_online_nodes() is a variable value, it can be changed after hot-remove/add
a node.
In my practice, I found node distance is wrong after offline
a node in IA64 platform. For example system has 4 nodes:
node distances:
node 0 1 2 3
0: 10 21 21 32
1: 21 10 32 21
2: 21 32 10 21
3: 32 21 21 10
linux-drf:/sys/devices/system/node/node0 # cat distance
10 21 21 32
linux-drf:/sys/devices/system/node/node1 # cat distance
21 10 32 21
After offline node2:
linux-drf:/sys/devices/system/node/node0 # cat distance
10 21 32
linux-drf:/sys/devices/system/node/node1 # cat distance
32 21 32 --------->expected value is: 21 10 21

In order to lay the foundation for 1G EEE support, several segments of code
which are common to both 1G and 10G EEE configurations were extracted from
the 10G EEE configuration flow to their own functions.
E.g., bnx2x_eee_initial_config, bnx2x_eee_advertise, bnx2x_eee_disable, etc.
The rest of the EEE functions were relocated and placed in a single,
continuous section of the file.

This was previously hidden because ixp4xx_hss includes linux/hdlc.h which
includes linux/netdevice.h which includes linux/netprio_cgroup.h which
used to include linux/module.h. The real issue was actually present since
the initial commit that added this driver since it uses macros from

This patch adds two sysfs files for each usb hub port to allow userspace
to control the port power policy.
For an upcoming Intel xHCI roothub, this will translate into ACPI calls
to completely power off or power on the port. As a reminder, when these
ports are completely powered off, the USB host and device will see a
physical disconnect. All future USB device connections will be lost,
and the device will not be able to signal a remote wakeup.
The control sysfs file can be written to with two options:
"on" - port power must be on.
"off" - port must be off.
The state sysfs file reports usb port's power state:
"on" - powered on
"off" - powered off
"error" - can't get power state
For now, let userspace dictate the port power off policy. Future
patches may add an in-kernel policy.

Alan Stern pointed out that a USB port could potentially get powered off
when the attached USB device is in the middle of enumerating, due to
race conditions:
http://marc.info/?l=linux-usb&m=134130616707548&w=2
If that happens, we need to ensure the enumeration fails. If a call to
usb_get_descriptor() fails for a reason other than a Stall, return an
error. That should handle the case where the port is powered off.

Upcoming Intel systems will have an ACPI method to control whether a USB
port can be completely powered off. The implication of powering off a
USB port is that the device and host sees a physical disconnect, and
subsequent port connections and remote wakeups will be lost.
Add a new function, usb_acpi_power_manageable(), that can be used to
find whether the usb port has ACPI power resources that can be used to
power on and off the port on these machines. Also add a new function
called usb_acpi_set_power_state() that controls the port power via these
ACPI methods.
When the USB core calls into the xHCI hub driver to power off a port,
check whether the port can be completely powered off via this new ACPI
mechanism. If so, call into these new ACPI methods. Also use the ACPI
methods when the USB core asks to power on a port.
