The Super-Isolate mode comes to isolate the BCM84833 PHY from the
outside world. Not doing it correctly, made link partner see the link
before the driver was loaded.This patch also involves SPIROM version fixes since it is used to
determine whether the common init of the PHY was already executed, and
the common init of this PHY is partially responsible for setting the
Super-Isolate mode.Signed-off-by: Yaniv Rosner

"It's an issue brought about by GCC 4.7's partial-inlining, that ends up
splitting the udelay function just at the wrong spot, in such a way that
some sanity checks for constants fails, and we end up calling

Documentation states that the KeyMiss flag is only valid if RxFrameOK is
unset, however empirical evidence has shown that this is false.
When KeyMiss is set (and RxFrameOK is 1), the hardware passes a valid frame
which has not been decrypted. The driver then falsely marks the frame
as decrypted, and when using CCMP this corrupts the rx CCMP PN, leading
to connection hangs.Signed-off-by: Felix Fietkau

This clears the currently mapped core when suspending, to force
re-mapping after resume. Without that we were touching default core
registers believing some other core is mapped. Such a behaviour

Same devices can generate interrupt without properly setting bit in
INT_SOURCE_CSR register (spurious interrupt), what will cause IRQ line
will be disabled by interrupts controller driver.We discovered that clearing INT_MASK_CSR stops such behaviour. We
previously first read that register, and then clear all know interrupt
sources bits and do not touch reserved bits. After this patch, we write
to all register content (I believe writing to reserved bits on that
register will not cause any problems, I tested that on my rt2800pci
device).This fix very bad performance problem, practically making device
unusable (since worked without interrupts), reported in:
https://bugzilla.redhat.com/show_bug.cgi?id=658451We previously tried to workaround that issue in commit
4ba7d9997869d25bd223dea7536fc1ce9fab3b3b "rt2800pci: handle spurious
interrupts", but it was reverted in commit
82e5fc2a34fa9ffea38f00c4066b7e600a0ca5e6

This is basically just a cleanup. Large positive numbers get counted as
negative but then get implicitly cast to positive again for the checks
that matter.This does make a small difference in ipw_handle_promiscuous_rx() when we
test "if (unlikely((len + IPW_RX_FRAME_SIZE) > skb_tailroom(rxb->skb)))"
It should return there, but we don't return until a couple lines later
when we test "if (len > IPW_RX_BUF_SIZE - sizeof(struct ipw_rt_hdr)) {".
The difference is that in the second test the sizeof() means that there
is an implied cast to unsigned.Signed-off-by: Dan Carpenter

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 eventWhen 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"

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).Signed-off-by: Manfred Rudigier

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

sock reference from the original skb after making the private copy.Signed-off-by: Manfred Rudigier

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).
