Pull x86 fixes from Thomas Gleixner:
 "The x86 updates contain:

   - A fix for a longstanding PAT bug, where PAT was reported on CPUs
     that do not support it, which leads to wrong caching attributes and
     missing MTRR updates

   - Prevent overwriting of the e820 firmware table, which causes kexec
     kernels to lose the fake mptable which is stored there.

   - Cleanup of the UV/BAU code, removing unused code and making local
     functions static"

  originally written by the Lustre team, and credit goes to Artem
  Blagodarenko from Seagate for getting this feature upstream.

  The second major major feature allows ext4 to support extended
  attribute values up to 64k. This feature was also originally from
  Lustre, and has been enhanced by Tahsin Erdogan from Google with a
  deduplication feature so that if multiple files have the same xattr
  value (for example, Windows ACL's stored by Samba), only one copy will
  be stored on disk for encoding and caching efficiency.

As Hongjun/Nicolas summarized in their original patch:

"
When a device changes from one netns to another, it's first unregistered,
then the netns reference is updated and the dev is registered in the new
netns. Thus, when a slave moves to another netns, it is first
unregistered. This triggers a NETDEV_UNREGISTER event which is caught by
the bonding driver. The driver calls bond_release(), which calls
dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in
the old netns).
"

This is a very special case, because the device is being unregistered
no one should still care about the NETDEV_CHANGEMTU event triggered
at this point, we can avoid broadcasting this event on this path,
and avoid touching inetdev_event()/addrconf_notify() path.

It requires to export __dev_set_mtu() to bonding driver.

====================
rds-tcp: sock_graft() leak

Following up on the discussion at
  https://www.spinics.net/lists/netdev/msg442859.html
- make rds_tcp_accept_one() call sock_create_lite()
- add a WARN_ON() to sock_graft()

Tested by running an infinite while() loop that does
(module-load; rds-stress; module-unload) and monitors
TCP slabinfo while the test is running.

sock_graft() unilaterally sets up parent->sk based on the
assumption that the existing parent->sk is null. If this
condition is not true, then the existing parent->sk would
be leaked, so add a WARN_ON() to alert callers who may fall
in this category.

Signed-off-by: NDavid S. Miller <davem@davemloft.net>

There are two problems with calling sock_create_kern() from
rds_tcp_accept_one()
1. it sets up a new_sock->sk that is wasteful, because this ->sk
   is going to get replaced by inet_accept() in the subsequent ->accept()
2. The new_sock->sk is a leaked reference in sock_graft() which
   expects to find a null parent->sk

Avoid these problems by calling sock_create_lite().

skb maybe freed in hns_nic_net_xmit_hw() and return NETDEV_TX_OK,
which cause hns_nic_net_xmit to use a freed skb.

by mdio should be data, but not address. Here we should fix this

As per the SAMA5D3 device specification it supports Jumbo frames.
But the suggested flag and length of bytes it supports was not updated
in this driver config_structure.
The maximum jumbo frames the device supports :
10240 bytes as per the device spec.

While changing the MTU value greater than 1500, it threw error:
sudo ifconfig eth1 mtu 9000
SIOCSIFMTU: Invalid argument

Add this support to driver so that it works as expected and designed.

Re-factor jprobe registration functions as the current version is
getting too unwieldy. Move the actual jprobe registration to
register_jprobe() and re-organize code accordingly.

In architectures that use qspinlock, like x86, prefetch is loaded
indirectly via the asm/qspinlock.h include.  On other architectures, like
OpenRISC, which may want to use asm-generic/qspinlock.h the built will
fail without the asm/prefetch.h include.

Fix this by including directly.
