Newer nVidia cards with Optimus do not support/use the DSM switching functions.
Instead, it require a DSM function to be called prior to bringing a device into
D3 state. No other _DSM calls are necessary before/after enabling/disabling a
device. Switching between discrete and integrated GPU is not supported by
this Optimus _DSM call, therefore return on the switching method.

At the moment we cannot allocate more than stolen memory size for framebuffers.
To get around that issues we discard modes that doesn't fit. This is a temporary
solution until we can freely allocate framebuffer memory.
[Currently the framebuffer needs to be linear in kernel space due to limits
in the kernel fb layer - AC]

Andrew explains:
- various misc stuff
- Most of the rest of MM: memcg, threaded hugepages, others.
- cpumask
- kexec
- kdump
- some direct-io performance tweaking
- radix-tree optimisations
- new selftests code
A note on this: often people will develop a new userspace-visible
feature and will develop userspace code to exercise/test that
feature. Then they merge the patch and the selftest code dies.
Sometimes we paste it into the changelog. Sometimes the code gets
thrown into Documentation/(!).
This saddens me. So this patch creates a bare-bones framework which
will henceforth allow me to ask people to include their test apps in
the kernel tree so we can keep them alive. Then when people enhance
or fix the feature, I can ask them to update the test app too.
The infrastruture is terribly trivial at present - let's see how it
evolves.
- checkpoint/restart feature work.
A note on this: this is a project by various mad Russians to perform
c/r mainly from userspace, with various oddball helper code added
into the kernel where the need is demonstrated.
So rather than some large central lump of code, what we have is
little bits and pieces popping up in various places which either
expose something new or which permit something which is normally
kernel-private to be modified.
The overall project is an ongoing thing. I've judged that the size
and scope of the thing means that we're more likely to be successful
with it if we integrate the support into mainline piecemeal rather
than allowing it all to develop out-of-tree.
However I'm less confident than the developers that it will all
eventually work! So what I'm asking them to do is to wrap each piece
of new code inside CONFIG_CHECKPOINT_RESTORE. So if it all
eventually comes to tears and the project as a whole fails, it should
be a simple matter to go through and delete all trace of it.
This lot pretty much wraps up the -rc1 merge for me.

Currently no udev events for memory hotplug "online" and "offline" are
generated:
# udevadm monitor
# echo offline > /sys/devices/system/memory/memory4/state
==> No event
When kdump is loaded, kexec detects the current memory configuration and
stores it in the pre-allocated ELF core header. Therefore, for kdump it
is necessary to reload the kdump kernel with kexec when the memory
configuration changes (e.g. for online/offline hotplug memory).
In order to do this automatically, udev rules should be used. This kernel
patch adds udev events for "online" and "offline". Together with this
kernel patch, the following udev rules for online/offline have to be added
to "/etc/udev/rules.d/98-kexec.rules":
SUBSYSTEM=="memory", ACTION=="online", PROGRAM="/etc/init.d/kdump restart"
SUBSYSTEM=="memory", ACTION=="offline", PROGRAM="/etc/init.d/kdump restart"

When TX time stamping for PTP messages is enabled on a socket, a time
stamp is returned on the socket error queue to the user space application
after the frame was transmitted. The transmitted frame is also returned on
the error queue so that an application knows to which frame the time stamp
belongs.
In the current implementation the TxFCB is immediately followed by the
frame. Since the eTSEC inserts the TX time stamp 8 bytes after the TxFCB,
parts of the frame have been overwritten and an invalid frame was returned
on the socket error queue.
This patch fixes the described problem by adding additional 16 padding
bytes between the TxFCB and the frame for all messages sent from a time
stamping enabled socket (other sockets are not affected).

When there is not enough headroom in the skb a private copy will be made.
However, the private copy had no reference to the socket and consequently
no time stamp could be queued on the socket error queue during the
skb_tstamp_tx function. This patch fixes this issue by also stealing the
sock reference from the original skb after making the private copy.

Introduce function mdiobus_alloc_size() as an alternative to mdiobus_alloc().
Most callers of mdiobus_alloc() also allocate a private data structure, and
then manually point bus->priv to this object. mdiobus_alloc_size()
combines the two operations into one, which simplifies memory management.
The original mdiobus_alloc() now just calls mdiobus_alloc_size(0).

It appears that you can only read the sprom contents with aligned 16-bit
reads: anything else causes at least some versions of the broadcom
chipset to abort the PCI transaction, returning 0xff.
This apparently doesn't trigger very often, because most setups don't
use an external srom chip, and the OTP sprom loading doesn't have this
issue. But at least the current 11" Macbook Air does trigger it, and
wireless communications were broken as a result.

Performing MMC block IO with simultaneous STR can lead to a deadlock: the
mmc_pm_notify() function claims the host and then calls bus .remove()
method, which lands in mmc_blk_remove(), which calls mmc_blk_remove_req()
then it goes to -> mmc_cleanup_queue() -> kthread_stop(), which waits for
the mmc-block thread to stop. If the mmc-block thread at that time is
processing block requests, it will also try to claim the host in
mmc_blk_issue_rq() and block there. This patch fixes the problem by
calling .remove() before claiming the host.

If dma is enabled, it'll be cleared when reset all is performed, this can
be observed on some platforms, such as P2041 which has a version 2.3
controller, but platform like P4080 which has a version 2.2 controller,
does not suffer this, so we will check if the dma is enabled, we should
restore it after reset all.

In FIFOTH register, the RX_WMark field (bits[27:16]) defaults to
FIFO_DEPTH - 1. When reading it, bits[26:16] were being used, so
fix it to use the mask 0xfff instead of 0x7ff.

This patch adds the support of the HS200 bus speed for eMMC 4.5 devices.
The eMMC 4.5 devices have support for 200MHz bus speed. The function
prototype of the tuning function is modified to handle the tuning
command number which is different in sd and mmc case.

Turning the cache off implies flushing cache which doesn't define
maximum timeout unlike cache-on. This patch will apply the generic
CMD6 timeout only for cache-on. Additionally the kernel message is
added for checking failure case of cache-on.

"mmc: sdhci: remove "state" argument from sdhci_suspend_host"
we get a compilation error for sdhci-spear:

If there are errors happened in sdhci_suspend_host, handle it so that
when the function returns with an error, the host's behaviour is the
same before this function call, e.g. card detection is enabled and
tuning timer is active, etc.

This patch fixes a failure to recognize SD cards reported on a Dell
Vostro with O2 Micro SD card reader. Patch 49c468f ("mmc: sd: add

Use memdup_user rather than duplicating its implementation.
This is a little bit restricted to reduce false positives.
