The energy detect enable/disable code in the driver uses some
register defines in this header unconditionally, so guarding
the smscphy.h header include with CONFIG_SMSC_PHY leads to
build failures in some configurations.

At this point if skb->len happens to be 2, the subsequant skb_pull(skb, 4)
call won't work and the skb->len won't be decreased and won't ever reach 0,
resulting in an infinite loop.
With an ASIX 88772 under heavy load, without this patch, rx_fixup() reaches
an infinite loop in less than a minute. With this patch applied,
no infinite loop even after hours of heavy load.

Commit 4e16d6ebd65b4f2c4e3f780b4c5704beef64019c (r6040: define more MCR0
register bits) added #define values for MCR0 register bits and converted
uses of hardcoded magic values to uses of these defines.
However, one of the conversions looks suspicious:
#define MCR0 0x00 /* Control register 0 */
+#define MCR0_RCVEN 0x0002 /* Receive enable */
+#define MCR0_XMTEN 0x1000 /* Transmission enable */
/* Init RDC private data */
- lp->mcr0 = 0x1002;
+ lp->mcr0 = MCR0_XMTEN | MCR0;
I believe what was meant here was MCR0_XMTEN | MCR0_RCVEN, which makes
sense and matches the original values.

mac_irq_pending() has only one caller (mac_esp.c). Nothing tests for Baboon, PSC or OSS pending interrupts. Until that need arises, let's keep it simple and remove all the unused abstraction. Replace it with a routine to check for SCSI DRQ.

This patch adds the necessary support in file2alias.c to define
suitable aliases based on the amba_id table in AMBA driver modules.
This should be sufficient to allow such modules to be auto-loaded
via udev. The AMBA bus driver's uevent hotplug code is also
modified to pass an approriate MODALIAS string in the event.
For simplicity, the AMBA ID is treated an an opaque 32-bit numeber.
Module alises use patterns as appropriate to describe the value-
mask pairs described in the driver's amba_id list.
The proposed alias format is (extended regex):
^amba:d(HEX){8}$
Where HEX is a single upper-case HEX digit or a pattern (? or []
expression) matching a single upper-case HEX digit, as expected by
udev.
"d" is short for "device", following existing alias naming
conventions for other device types. This adds some flexibility for
unambiguously extending the alias format in the future by adding
additional leading and trailing fields, if this turns out to be
necessary.

This allows a backend to filter on the dmesg reason as well as the pstore
reason. When ramoops is switched to pstore, this is needed since it has
no interest in storing non-crash dmesg details.
Drop pstore_write() as it has no users, and handling the "reason" here
has no obviously correct value.

When using a >8bpp framebuffer, offb advertises truecolor, not directcolor,
and doesn't touch the color map even if it has a corresponding access method
for the real hardware.
Thus it needs to set the pseudo-palette with all 3 components of the color,
like other truecolor framebuffers, not with copies of the color index like
a directcolor framebuffer would do.
This went unnoticed for a long time because it's pretty hard to get offb
to kick in with anything but 8bpp (old BootX under MacOS will do that and
qemu does it).

We rename the mach64 hack to "simple" since that's also applicable
to anything using VGA-style DAC IO ports (set to 8-bit DAC) and we
use it for qemu vga.
Note that this is keyed on a device-tree "compatible" property that
is currently only set by an upcoming version of SLOF when using the
qemu "pseries" platform. This is on purpose as other qemu ppc platforms
using OpenBIOS aren't properly setting the DAC to 8-bit at the time of
the writing of this patch.
We can fix OpenBIOS later to do that and add the required property, in
which case it will be matched by this change.

This patch reworks & simplifies pmac_zilog handling of suspend/resume,
essentially removing all the specific code in there and using the
generic uart helpers.
This required properly registering the tty as a child of the macio (or platform)
device, so I had to delay the registration a bit (we used to register the ports
very very early). We still register the kernel console early though.
I removed a couple of unused or useless flags as well, relying on the
core to not call us when asleep. I also removed the essentially useless
interrupt mutex, simplifying the locking a bit.
I removed some code for handling unexpected interrupt which should never
be hit and could potentially be harmful (causing us to access a register
on a powered off SCC). We diable port interrupts on close always so there
should be no need to drain data on a closed port.

On most 68k Macs the SCC IRQ is an autovector interrupt and cannot be
masked. This can be a problem when pmac_zilog starts up.
For example, the serial debugging code in arch/m68k/kernel/head.S may be
used beforehand. It disables the SCC interrupts at the chip but doesn't
ack them. Then when a pmac_zilog port is used, the machine locks up with
"unexpected interrupt".
This can happen in pmz_shutdown() since the irq is freed before the
channel interrupts are disabled.
Fix this by clearing interrupt enable bits before the handler is
uninstalled. Also move the interrupt control bit flipping into a separate
pmz_interrupt_control() routine. Replace all instances of these operations
with calls to this routine. Omit the zssync() calls that seem to serve no
purpose.

The UCC UART driver is missing a call to uart_update_timeout().
Without this call, attempting to close the port after outputting large
amounts of data (i.e. using tty and uart buffering) results in long
timeouts before the port will actually be shut down.
For example, cat a large file to a UCC UART port. With the current
driver, the port will stay open for 30 seconds after the last byte
of data is output. But with this patch, the port is closed as
expected, just after the data has been output (tx fifos empty).

When a bnx2x device encounters parity errors, it will not respond to all
SPQ messages. As a result, the shutdown sequence before reset can take
a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
of all such messages.
To improve this scenario, when bnx2x returns error on the SPQ, we'll send
an immediate response to the ulp drivers to avoid such lengthy timeouts.
Adjust the return code of relevant functions to return error only if
the message cannot be sent on the SPQ so that we'll generate an error
completion to the ulp drivers.

because bnx2x frees the old and allocates new memory during chip reset.

This fixes a several sparse warnings.
* the __iomem tag was being used incorrectly (needs to be a prefix)
* several variables should have been static since local to one file
* the firmware was not being forwared declared
and was const one place and not the other

Auditing all usage of ethtool_ops found several drivers that
are not declaring the struct const when it should be.

Currently, the refill path for RX buffers will always allocate the
buffers as GFP_ATOMIC, even if we are in process context. This will
fail to apply memory pressure as the worker thread will not contribute
to the freeing of memory.
Fix this by changing add_recvbuf_small to use the gfp variant allocator,
__netdev_alloc_skb_ip_align().

This patch implements support for ndo_get_fcoe_hbainfo()
call in the ixgbe driver.
This function will be called by the FCoE protocol stack to
obtain device specific information from the underlying
device configured to do FCoE.

According to 82576_Datasheet.pdf, PHY setting is lost after PHY power down.
So resetting PHY is needed when recovering from PHY power down to set a default
setting to PHY register.
Owing to this lack, NIC doesn't link up in some rare situation.

Use the runtime power management framework to add basic runtime PM support
to the igb driver. Namely, make the driver suspend the device when the link
is off and set it up for generating a wakeup event after the link has been
detected again. This feature is disabled by default.
Based on e1000e's runtime PM code.
Changes since v1:
Don't suspend the device when shutting down the interface.
Avoid race between runtime suspending and ethtool operations.
