The SMU driver has a small mistake in the locking of the interrupt code,
if polled access and interrupt access race, interrupt may take a lock
and return without releasing it. This fixes it. With that patch, the
driver is rock solid with my experimental thermal control (which bangs
it pretty hard) racing with real time clock and cpufreq handling.

When creating a multipath device, if the queue_if_no_path parameter is
specified it gets ignored.
While the queue_if_no_path variable is correctly set to 1, the
saved_queue_if_no_path gets set to 0. When the device is subsequently made
live (resumed), the saved value (0) always overwrites the live value (1) so
the option *always* gets turned off.
The fix adds a parameter to the queue_if_no_path() function to indicate
whether the previous value should be preserved or not - if not, as when the
device is being set up, the saved value is set to the new value (1).

Fix 5780 PHY related problems:
1. MAC_RX_MODE reset must be done before setting up the MAC_MODE
register on 5705_PLUS chips or the chip will stop receiving after
a while. The MAC_RX_MODE reset is needed to prevent intermittently
losing the first receive packet on serdes chips.
2. Skip MAC loopback test on 5780 because of hardware errata. Normal
traffic including PHY loopback is not affected by the errata.
3. PHY loopback fails intermittently on 5708S and this is fixed by
putting the PHY in loopback mode first before programming the MAC
mode register. A MAC_RX_MODE reset is also added.

In interrupt probing (both ISA and PCI) the bridge control register is used

only controls the routing of card functional interrupts, not the CSC
interrupts which are used for interrupt probing.
A bad side effect of messing with this register in yenta_probe_irq() is
that it can lead to irq storms if a card is inserted and already powered by

This function expects an unsigned 32-bit type as its third argument:
static u32 pci_size(u32 base, u32 maxbase, u32 mask)
However, given these definitions:
#define PCI_BASE_ADDRESS_MEM_MASK (~0x0fUL)
#define PCI_ROM_ADDRESS_MASK (~0x7ffUL)
these two calls in drivers/pci/probe.c are problematic for architectures
for which a UL is not equivalent to a u32:
sz = pci_size(l, sz, PCI_BASE_ADDRESS_MEM_MASK);
sz = pci_size(l, sz, PCI_ROM_ADDRESS_MASK);
Hence the below compile warning when building for ARCH=ppc64:
drivers/pci/probe.c: In function `pci_read_bases':
/.../probe.c:168: warning: large integer implicitly truncated to unsigned type
/.../probe.c:218: warning: large integer implicitly truncated to unsigned type
Here is a simple fix.

The class symlinks in sysfs don't properly handle changing device names.
To demonstrate, rename your network device from eth0 to eth1. Your
pci (or usb, or whatever) device will still have a 'net:eth0' link,
except now it points to /sys/class/net/eth1.
The attached patch makes sure the class symlink name changes when
the class device name changes. It isn't 100% correct, it should be
using sysfs_rename_link. Unfortunately, sysfs_rename_link doesn't exist.

add the helper and use it instead of open coding the klist_node_attached() check
(which is a layering violation IMHO)

bus_rescan_devices_helper() does not hold the dev->sem when it checks for
!dev->driver(). device_attach() holds the sem, but calls again
device_bind_driver() even when dev->driver is set.
What happens is that a first device_attach() call (module insertion time)
is on the way binding the device to a driver. Another thread calls
bus_rescan_devices(). Now when bus_rescan_devices_helper() checks for
dev->driver it is still NULL 'cos the the prior device_attach() is not yet
finished. But as soon as the first one releases the dev->sem the second
device_attach() tries to rebind the already bound device again.
device_bind_driver() does this blindly which leads to a corrupt
driver->klist_devices list (the device links itself, the head points to the
device). Later a call to device_release_driver() sets dev->driver to NULL
and breaks the link it has to itself on knode_driver. Rmmoding the driver
later calls driver_detach() which leads to an endless loop 'cos the list
head in klist_devices still points to the device. And since dev->driver is
NULL it's stuck with the same device forever. Boom. And rmmod hangs.
Very easy to reproduce with new-style pcmcia and a 16bit card. Just loop
modprobe <pcmcia-modules> ;cardctl eject; rmmod <card driver, pcmcia
modules>.
Easiest fix is to check if the device is already bound to a driver in
device_bind_driver(). This avoids the double binding.

Expand the returned data for ethtool debug access to include
all of the mapped PCI area; except for the small set of registers
that are for diagnostic RAM access. Access to those registers
will hang the system.
