Pull core debug changes from Ingo Molnar:
"Currently there are two methods to set the panic_timeout: via
'panic=X' boot commandline option, or via /proc/sys/kernel/panic.
This tree adds a third panic_timeout configuration method:
configuration via Kconfig, via CONFIG_PANIC_TIMEOUT=X - useful to
distros that generally want their kernel defaults to come with the
.config.
CONFIG_PANIC_TIMEOUT defaults to 0, which was the previous default
value of panic_timeout.
Doing that unearthed a few arch trickeries regarding arch-special
panic_timeout values and related complications - hopefully all
resolved to the satisfaction of everyone"

modules all being set, I discovered a small bug in the dependency
logic.
If a config has a dependency based on its setting value, localmodcondig
misses it.
For example:
config FOO
default y if BAR || ZOO
If FOO is needed for a module and is set to '=m', and so are BAR or ZOO,
localmodconfig will not see that BAR or ZOO are also needed for the foo
module, and will incorrectly disable them.

A host controller for a SD card may need a GPIO for card detect in order
to wake up from runtime suspend when a card is inserted. If that GPIO is
not configured, then the host controller will not wake up. Fix that for
the affected devices by not enabling runtime PM unless the GPIO is
successfully set up.
This affects BYT sd card host controller which had runtime PM enabled from
v3.11. For completeness, the MFD sd card host controller is flagged also.
The original patch before rebasing (see link below) was tested on v3.11.10
and v3.12.4 although the patch applied with some offsets and fuzz. The
original patch is here:

that. Change the timer timeout to reflect the command timeout.

Seems that commit 210b160701
(KVM: s390: Removed SIE_INTERCEPT_UCONTROL) lost a hunk when we
reworked our patch queue to rework the async_fp code. We now
ignore faults on the sie instruction (guest accesses non-existing
memory) instead of sending a fault into the guest. This leads to
hang situations with the old virtio transport that checks for
descriptor memory after guest memory. Instead of bailing out this
code now goes wild...
Lets re-add the check.

None of the devices supported by iwldvm have support for
shadow registers. This means that we wake the NIC
when we increment the write pointer on Tx ring.
This happened even before my bad commit mentionned below.
Since my commit below, we wake up the NIC when we put a
host command on the ring regardless of shadow register
support. This means that in iwldvm (when the NIC doesn't
support shadow register), we wake up the NIC twice:
pcie_enqueue_hcmd:
wake up the NIC
iwl_pcie_txq_inc_wr_ptr:
wake up the NIC - no shadow reg support
Since waking up the NIC means that we need to acquire a
spinlock, this obviously leads to a recursive spinlock
and hence a freeze.

When timestamping is enabled, stmmac_tx_clean will call
stmmac_get_tx_hwtstamp to get tx TS.
But the skb can be NULL because the last of its tx_skbuff is NULL
if this packet frame is filled in more than one descriptors.
To fix the issue, change the code:
- Store TX skb to the tx_skbuff[] of frame's last segment.
- Check skb is not NULL in stmmac_get_tx_hwtstamp.

The Allwinner A20 has an ethernet controller that seems to be
an early version of Synopsys DesignWare MAC 10/100/1000 Universal,
which is supported by the stmmac driver.
Allwinner's GMAC requires setting additional registers in the SoC's
clock control unit.
The exact version of the DWMAC IP that Allwinner uses is unknown,
thus the exact feature set is unknown.

The snps,phy-addr device tree property is non-standard, and should be
removed in favor of proper phy node support. Remove it from the binding
documents and warn if the property is still used.
Most PHYs respond to address 0, but a few don't, so auto-detect PHY
address by default, to make up for the lack of explicit address selection.

Though described as required, the "phy-handle" property for the DaVinci EMAC
binding is actually optional, as the driver will happily function without it,
assuming 100/FULL link; the property is not specified either in the example
device node, or in the actual EMAC device nodes for DA850 and AM3517 device
trees.

ipv6_link_dev_addr sorts newly added addresses by scope in
ifp->addr_list. Smaller scope addresses are added to the tail of the
list. Use this fact to iterate in reverse over addr_list and break out
as soon as a higher scoped one showes up, so we can spare some cycles
on machines with lot's of addresses.
The ordering of the addresses is not relevant and we are more likely to
get the eui64 generated address with this change anyway.

We currently don't report IPV6_RECVPKTINFO in cmsg access ancillary data
for IPv4 datagrams on IPv6 sockets.
This patch splits the ip6_datagram_recv_ctl into two functions, one
which handles both protocol families, AF_INET and AF_INET6, while the
ip6_datagram_recv_specific_ctl only handles IPv6 cmsg data.
ip6_datagram_recv_*_ctl never reported back any errors, so we can make
them return void. Also provide a helper for protocols which don't offer dual
personality to further use ip6_datagram_recv_ctl, which is exported to
modules.
I needed to shuffle the code for ping around a bit to make it easier to
implement dual personality for ping ipv6 sockets in future.
