This driver supports iLO, iLO2 and iLO3. However, comments and Kconfig
reference only iLO and iLO2. Let's just call it "iLO" to avoid having to
update strings for each iLO generation. This is similar to the change made
to hpwdt in commit 36e3ff44ce.

Modify link_mem_sections() to pass in the previous mem_block as a hint to
locating the next mem_block. Since they are typically added in order this
results in a massive saving in time during boot of a very large system.
For example, on a 16TB x86_64 machine, it reduced the total time spent
linking all node's memory sections from 1 hour, 27 minutes to 46 seconds.

I have some systems which need legacy sysfs due to old tools that are
making assumptions that a directory can never be a symlink to another
directory, and it's a big hazzle to compile separate kernels for them.
This patch turns CONFIG_SYSFS_DEPRECATED into a run time option
that can be switched on/off the kernel command line. This way
the same binary can be used in both cases with just a option
on the command line.
The old CONFIG_SYSFS_DEPRECATED_V2 option is still there to set
the default. I kept the weird name to not break existing
config files.
Also the compat code can be still completely disabled by undefining
CONFIG_SYSFS_DEPRECATED_SWITCH -- just the optimizer takes
care of this now instead of lots of ifdefs. This makes the code
look nicer.

Some users of platform_device_add_{data,resources}() assume that

But the platform core ends up calling kmemdup(NULL, 0, ...), which
returns a non-NULL result (i.e. ZERO_SIZE_PTR), which causes drivers
to oops on a valid code, something like:
if (platform_data)
stuff = platform_data->stuff;

Packet hub driver of Topcliff PCH
Topcliff PCH is the platform controller hub that is going to be used in
Intel's upcoming general embedded platform. All IO peripherals in
Topcliff PCH are actually devices sitting on AMBA bus. Packet hub is
a special converter device in Topcliff PCH that translate AMBA transactions
to PCI Express transactions and vice versa. Thus packet hub helps present
all IO peripherals in Topcliff PCH as PCIE devices to IA system.
Topcliff PCH has MAC address and Option ROM data.
These data are in SROM which is connected to PCIE bus.
Packet hub driver of Topcliff PCH can access MAC address and Option ROM data in
SROM via sysfs interface.

Currently, the platform_bus allows customization of several of the
busses dev_pm_ops methods by using weak symbols so that platform code
can override them. The weak-symbol approach is not scalable when
wanting to support multiple platforms in a single kernel binary.
Instead, provide __init methods for platform code to customize the
dev_pm_ops methods at runtime.
NOTE: after these dynamic methods are merged, the weak symbols should
be removed from drivers/base/platform.c. AFAIK, this will only
affect SH and sh-mobile which should be converted to use this
runtime approach instead of the weak symbols. After SH &
sh-mobile are converted, the weak symobols could be removed.

If the host is slow in reading data or doesn't read data at all,
blocking write calls not only blocked the program that called write()
but the entire guest itself.
To overcome this, let's not block till the host signals it has given
back the virtio ring element we passed it. Instead, send the buffer to
the host and return to userspace. This operation then becomes similar
to how non-blocking writes work, so let's use the existing code for this
path as well.
This code change also ensures blocking write calls do get blocked if
there's not enough room in the virtio ring as well as they don't return
-EAGAIN to userspace.

The i2c_imx_trx_complete() function is using
wait_event_interruptible_timeout() to wait for the I2C controller to
signal that it has completed an I2C bus operation. If the process that
causes the I2C operation receives a signal, the wait will be
interrupted, returning an error. It is better to let the I2C operation
finished before handling the signal (i.e. returning into userspace).
It is safe to use wait_event_timeout() instead, because the timeout
will allow the process to exit if the I2C bus hangs. It's also better
to allow the I2C operation to finish, because unacknowledged I2C
operations can cause the I2C bus to hang.

The compat code for the VIDIOCSMICROCODE ioctl is totally buggered.
It's only used by the VIDEO_STRADIS driver, and that one is scheduled to
staging and eventually removed unless somebody steps up to maintain it
(at which point it should use request_firmware() rather than some magic
ioctl). So we'll get rid of it eventually.
But in the meantime, the compatibility ioctl code is broken, and this
tries to get it to at least limp along (even if Mauro suggested just
deleting it entirely, which may be the right thing to do - I don't think
the compatibility translation code has ever worked unless you were very

PM: Device pxa2xx-mci.0 failed to suspend: error -38
PM: Some devices failed to suspend
4c2ef25fe0 moved the card removal/insertion mechanism out of MMC's
suspend/resume path and into pm notifiers (mmc_pm_notify), and that
broke SDIO's expectation that mmc_suspend_host() will remove the card,
and squash the error, in case -ENOSYS is returned from the bus suspend
handler (mmc_sdio_suspend() in this case).
mmc_sdio_suspend() is using this whenever at least one of the card's SDIO
function drivers does not have suspend/resume handlers - in that case
it is agreed to force removal of the entire card.
This patch fixes this regression by trivially bringing back that part of
mmc_suspend_host(), which was removed by 4c2ef25fe0.

At least one board using the FEC driver does not have a conventional
PHY attached to it, it is directly connected to a somewhat simple
ethernet switch (the board is the SnapGear/LITE, and the attached
4-port ethernet switch is a RealTek RTL8305). This switch does not
present the usual register interface of a PHY, it presents nothing.
So a PHY scan will find nothing - it finds ID's of 0 for each PHY
on the attached MII bus.
After the FEC driver was changed to use phylib for supporting PHYs
it no longer works on this particular board/switch setup.
Add code support to use a fixed phy if no PHY is found on the MII bus.
This is based on the way the cpmac.c driver solved this same problem.
