With a sparc64 defconfig modified to set CONFIG_HOTPLUG=n
the following error happened during link of vmlinux:
local symbol 0: discarded in section `.devexit.text' from drivers/built-in.o
local symbol 1: discarded in section `.devexit.text' from drivers/built-in.o
(The error message above is from kbuild.git but it happens in mainline too)
The error happens becase there is a reference from .text/.data to a
function marked __devexit. With CONFIG_HOTPLUG=n all code marked
__devexit are discarded and the linker complains.
It was tracked down to sparcspkr.c which were missing __devexit_p()
around the function pointers.
Unfortunately modpost did not catch this since modpost do not warn
about references from .data to .devexit from variables named *_driver.

The JMPRS register on Malta boards keeps a 32-bit CPU-endian
value. The readw() function assumes that the value it reads is a
little-endian 16-bit number. Therefore, using readw() to obtain
the value of the JMPRS register is a mistake. This error leads
to incorrect reading of the PCI clock frequency on big-endian
during board start-up.
Change readw() to __raw_readl().
This was tested by injecting a call to printk() and verifying
that the value of the jmpr variable was consistent with current
setting of the JP4 "PCI CLK" jumper.

This driver supports the application buttons on some Fujitsu Lifebook
laptops. It is based on the earlier apanel driver done by Jochen Eisenger,
but with many changes. The original driver used ioctl's and a separate
user space program (see http://apanel.sourceforge.net). This driver hooks
into the input subsystem so that the normal keys act as expected without a
daemon. In addition to buttons, the Mail Led is handled via LEDs class
device.
The driver now supports redefinable keymaps and no longer has to have a DMI
table for all Fujitsu laptops.
I thought about mixing this driver should be integrated into the Fujitsu
laptop extras driver that handles backlight, but rejected the idea because
it wasn't clear if all the Fujitsu laptops supported both.

When unregistering the rtnl_link_ops, all existing devices using
the ops are destroyed. With nested devices this may lead to a
use-after-free despite the use of for_each_netdev_safe() in case
the upper device is next in the device list and is destroyed
by the NETDEV_UNREGISTER notifier.
The easy fix is to restart scanning the device list after removing
a device. Alternatively we could add new devices to the front of
the list to avoid having dependant devices follow the device they
depend on. A third option would be to only restart scanning if
dev->iflink of the next device matches dev->ifindex of the current
one. For now this seems like the safest solution.
With this patch, the veth rtnl_link_ops unregistration can use
rtnl_link_unregister() directly since it now also handles destruction
of multiple devices at once.

When packets are flood-forwarded to multiple output devices, the
bridge-netfilter code reuses skb->nf_bridge for each clone to store
the bridge port. When queueing packets using NFQUEUE netfilter takes
a reference to skb->nf_bridge->physoutdev, which is overwritten
when the packet is forwarded to the second port. This causes
refcount unterflows for the first device and refcount leaks for all
others. Additionally this provides incorrect data to the iptables
physdev match.
Unshare skb->nf_bridge by copying it if it is shared before assigning
the physoutdev device.

We omit (or delay) sending NSes for known-to-unreachable routers (in
NUD_FAILED state) according to RFC 4191 (Default Router Preferences
and More-Specific Routes). But this is not fully compatible with RFC
4861 (Neighbor Discovery Protocol for IPv6), which does not remember
unreachability of neighbors.
So, let's avoid mixing sending algorithm of RFC 4191 and that of RFC
4861, and make the algorithm more friendly with RFC 4861 if RFC 4191
is disabled.
