NF_CT_TUPLE_DUMP prints IPv4 addresses as IPv6, fix this and use printk
(guarded by #ifdef DEBUG) directly instead of pr_debug since the tuple
is usually printed at the end of line and we don't want to include a

This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop. The
BIOS reports the interrupt routing incorrectly. I recently added a
quirk to work around this, and this patch fixes a typo in the quirk.
We pad every ACPI pathname component to four characters, so ".ISA." will
never match anything. We need ".ISA_." instead.
Thank you Johann-Nikolaus Andreae <johann-nikolaus.andreae@nacs.de>

This adds a kernel command line option "phyp_dump", which takes a 0/1
value for disabling/ enabling phyp_dump at boot time. Kdump can use
this on cmdline (phyp_dump=0) to disable phyp-dump during boot when
enabling itself. This will ensure only one dumping mechanism is active
at any given time.

Check to see if there actually is data from a previously
crashed kernel waiting. If so, allow user-space tools to
grab the data (by reading /proc/kcore). When user-space
finishes dumping a section, it must release that memory
by writing to sysfs. For example,
echo "0x40000000 0x10000000" > /sys/kernel/release_region
will release 256MB starting at the 1GB. The released memory
becomes free for general use.

The hypervisor can look at the value in the wait_state_cycles field of
the VPA for an estimate of how busy dedicated processors are.
Currently, as the kernel never touches this field, we appear to be
100% busy. This records the duration the kernel is in powersave and
passes that to the HV to provide a reasonable indication of
utilisation.

Prevailing practice for define_machine() in powerpc is to use the
platform name when the platform has only one define_machine()
statement, but maple uses "maple_md". This caused me some
head-scratching when writing some new code that uses
machine_is(maple).
Use "maple" instead of "maple_md". There should not be any behavioral
change -- fixup_maple_ide() calls machine_is(maple) but the body of
the function is ifdef'd out.

rt73usb and rt2500usb used in_atomic to determine
if a configuration step should be rescheduled or not.
Since in_atomic() is not a valid method to determine
if sleeping is allowed we should fix the way this is handled
by adding a new flag to rt2x00.
In addition mark LED class support for the drivers broken
since that also uses the broken in_atomic() method but
so far no solution exists to have LED triggers work only
in scheduled context.

It has been observed on rt2500pci hardware that some
frames received with signal 0x0C do not have the OFDM
flag set.
Signals can have 2 meanings:
1) The PLCP value
2) The bitrate * 10
For rt2500pci (1) is for frames received with a OFDM rate,
and (2) is for frames received with a CCK rate.
But 0x0C is a invalid bitrate value but is a valid PLCP
value for 54Mbs (obvious OFDM rate).
This means that it is possible that the hardware does not
set the OFDM bit correctly under all circumstances.
This results in rt2x00 failing to detect the rate and
mac80211 triggering a WARN_ON() and dropping the frame.
To bypass this, print a warning when such a frame is received,
and reset the rate to the lowest supported rate for the current band.

When you have an AP on channel 13, it will currently often enough
be listed in scan results even when the regulatory domain restricts
to channels 1-11. This is due to channel overlap. To avoid getting
very strange failures, don't show such APs in the scan results. The
failure mode will now go from "I can see the AP but not associate"
to "I can't see the AP although I know it's there" which is easier
to debug.
This problem was first really noticed by Jes Sorensen.
