4580ccc04d sctp: user perfect name for Delayed SACK Timer option
The option name of Delayed SACK Timer should be SCTP_DELAYED_SACK,
not SCTP_DELAYED_ACK.

Left SCTP_DELAYED_ACK be concomitant with SCTP_DELAYED_SACK,
for making compatibility with existing applications.

9032160275 x86: Unify "numa=" command line option handling
In order to be able to suppress the use of SRAT tables that
32-bit Linux can't deal with (in one case known to lead to a
non-bootable system, unless disabling ACPI altogether), move the
"numa=" option handling to common code.

6b35eb9ddc Revert "x86: Make relocatable kernel work with new binutils"
This reverts commit 86b1e8dd83 ("x86: Make relocatable kernel work with
new binutils").

Markus Trippelsdorf reported a boot failure caused by this patch.

The real solution to the original patch will likely involve an
arch-generic solution to define an overlaid jiffies_64 and jiffies
variables.

Until that's done and tested on all architectures revert this commit to
solve the regression.

In netif_skb_features() we return only the features that are valid for vlans
if we have a vlan packet.  However, we should not mask out NETIF_F_HW_VLAN_TX
since it enables transmission of vlan tags and is obviously valid.

1956cc52e7 ns83820: Avoid bad pointer deref in ns83820_init_one().
In drivers/net/ns83820.c::ns83820_init_one() we dynamically allocate
memory via alloc_etherdev(). We then call PRIV() on the returned storage
which is 'return netdev_priv()'. netdev_priv() takes the pointer it is
passed and adds 'ALIGN(sizeof(struct net_device), NETDEV_ALIGN)' to it and
returns it. Then we test the resulting pointer for NULL, which it is
unlikely to be at this point, and later dereference it. This will go bad
if alloc_etherdev() actually returned NULL.

This patch reworks the code slightly so that we test for a NULL pointer
(and return -ENOMEM) directly after calling alloc_etherdev().

2fdc1c8093 ipv6: Silence privacy extensions initialization
When a network namespace is created (via CLONE_NEWNET), the loopback
interface is automatically added to the new namespace, triggering a
printk in ipv6_add_dev() if CONFIG_IPV6_PRIVACY is set.

This is problematic for applications which use CLONE_NEWNET as
part of a sandbox, like Chromium's suid sandbox or recent versions of
vsftpd. On a busy machine, it can lead to thousands of useless
"lo: Disabled Privacy Extensions" messages appearing in dmesg.

It's easy enough to check the status of privacy extensions via the
use_tempaddr sysctl, so just removing the printk seems like the most
sensible solution.

3f348c5d1a MIPS: ath79: add common GPIO buttons device
Almost all boards have one or more push buttons connected to GPIO lines.
This patch adds common code to register a platform_device for them.

The patch also adds support for the buttons on the PB44 board.

858f763c1c MIPS: ath79: add common watchdog device
All supported SoCs have a built-in hardware watchdog driver. This patch
registers a platform_device for that to make it usable.

d4a67d9dc8 MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs
This patch adds initial support for various Atheros SoCs based on the
MIPS 24Kc core. The following models are supported at the moment:

  - AR7130
  - AR7141
  - AR7161
  - AR9130
  - AR9132
  - AR7240
  - AR7241
  - AR7242

The current patch contains minimal support only, but the resulting
kernel can boot into user-space with using of an initramfs image on
various boards which are using these SoCs. Support for more built-in
devices and individual boards will be implemented in further patches.

94bb0c1ab2 MIPS: jump label: Add MIPS support.
In order not to be left behind, we add jump label support for MIPS.

Tested on 64-bit big endian (Octeon), and 32-bit little endian
(malta/qemu).

8d662c8d34 MIPS: Use WARN() in uasm for better diagnostics.
On the off chance that uasm ever warns about overflow, there is no way
to know what the offending instruction is.

Change the printks to WARNs, so we can get a nice stack trace.  It has
the added benefit of being much more noticeable than the short single
line warning message, so is less likely to be ignored.
