The old function rt2x00queue_payload_align() handled
both adding and removing L2 padding and some basic
frame alignment. The entire function was being abused
because it had multiple functions and the header length
argument was somtimes used to align the header instead
of the payload.
Additionally there was a bug when inserting L2 padding
that only the payload was aligned but not the header. This
happens when the header wasn't aligned properly by mac80211,
but rt2x00lib only moves the payload.
A secondary problem was that when removing L2 padding during
TXdone or RX the skb wasn't resized to the proper size.
Split the function into seperate functions each handling
its task as it should.

Significant literature suggests users use debug flags 0x43fff - this causes
the debug flags to be set that causes information to be printed for every

at worst it slows driver down and causes failures due to timeouts.

Some concerns were raised about the automatic adjustment
of sleep intervals to all the same, potentially high,
value, and I can imagine the hardware behaving better
when we don't ask too much of it.
So let's convert to use a succession of sleep levels
when requesting to go to deeper sleeps (which can only
happen with large DTIM intervals), using the succession
values from power level three, which have the benefit of
also having been tested extensively already.
As a result, the automatic sleep level adjustment will
now be mostly equivalent to power level three, except
for the RX/TX timeouts and possibly using smaller sleep
vectors to account for networking latency.

For HT packets, mac80211 expects the rate_idx to be an MCS number, which is the
lower byte of rate_n_flags. However, iwl_hwrate_to_plcp_idx takes the MCS
number and reduces it down to the range 0-8 (6 to 60 Mbps), removing the bits
that signify multiply streams, HT40 Duplicate mode, or unequal modulation.
This version is used for various internal purposes through the driver.
Add the function iwl_hwrate_get_mac80211_idx, an alternate version which takes
the rate and the band and returns the mac80211 index (MCS, for HT packets, and
PLCP rate, for legacy packets).

Refactor and correct rate selection for outgoing transmitted
packets.
First, note that HT rates in the mac80211 rate table do not provide valid
indices when ieee80211_get_tx_rate is called; the check to see if we could to
abort a transmission early in iwl_tx_skb() would thus occasionally read invalid
memory and occasionally stall transmission (if the erroneous byte was 0xff).
We remove that code; the check wasn't valid anyway.
Second, iwl_tx_cmd_build_rate() also called ieee80211_get_tx_rate to be used
for sending management packets, which do not use the uCode station table. This
patch refactors that function and adds comments to enhance legibility, replaces
the call to ieee80211_get_tx_rate() with a direct lookup, and adds error
handling in case the table entry is invalid.

CONFIG_PAGEFLAGS_EXTENDED disables a trick to conserve pageflags.
This trick is indended to be enabled when the pressure on page flags
is very high.
The previous condition was:
- depends on 64BIT || SPARSEMEM_VMEMMAP || !NUMA || !SPARSEMEM
... however, the sparsemem code already has a way to crowd out the
node number from the pageflags, which means that !NUMA actually
doesn't contribute to hard pageflags exhaustion.
This is required for the new PG_uncached flag to not cause pageflags
exhaustion on x86_32 + PAE + SPARSEMEM + !NUMA.

This allows an architecture to specify per lock variant if the
locking code should be kept out-of-line or inlined.
If an architecure wants out-of-line locking code no change is
needed. To force inlining of e.g. spin_lock() the line:
#define __always_inline__spin_lock
needs to be added to arch/<...>/include/asm/spinlock.h
If CONFIG_DEBUG_SPINLOCK or CONFIG_GENERIC_LOCKBREAK are
defined the per architecture defines are (partly) ignored and
still out-of-line spinlock code will be generated.

m68k has the thread_info structure embedded in its task struct.
Therefore its not possible to implement current_thread_info()
by looking at the stack pointer and do some simple calculations
like most other architectures do it.
To return the thread_info pointer for a task two defines are
used. This works until the spinlock function bodies get moved
into an own header file and CONFIG_SPINLOCK_DEBUG is turned on.
That results into this compile error:
In file included from include/linux/spinlock.h:378,
from include/linux/seqlock.h:29,
from include/linux/time.h:8,
from include/linux/timex.h:56,
from include/linux/sched.h:54,
from arch/m68k/kernel/asm-offsets.c:12:
include/linux/spinlock_api_smp.h: In function '__spin_unlock_irq':
include/linux/spinlock_api_smp.h:371: error: 'current' undeclared (first use in this function)
include/linux/spinlock_api_smp.h:371: error: (Each undeclared identifier is reported only once
include/linux/spinlock_api_smp.h:371: error: for each function it appears in.)
Including asm/current.h to asm-offsets.c wouldn't help since
the definition of struct task is needed. So we end up with ugly
header file include dependencies.
To solve this calculate the offset of the thread_info structure
into the task struct in asm-offsets.h and use the offset in
task_thread_info(). This works just like it does for IA64 as
well.

In order to be able to use asm-offsets.h in C files the
existing namespace conflicts must be solved first. In
asm-offsets.h e.g. PT_D0 gets defined which is the offset of
the d0 member of the pt_regs structure. However a same define
(with a different meaning) exists in asm/ptregs.h.
So rename the defines created with the asm-offset mechanism to
PT_OFF_D0 etc. There also already exist a few defines with
these names that have the same meaning. So remove the existing
defines and use the asm-offset generated ones.

Add handling of incoming ICMPv6 messages.
This follows the handling of IPv4 ICMP messages.
Amongst ther things this problem allows IPVS to behave sensibly
when an ICMPV6_PKT_TOOBIG message is received:
This message is received when a realserver sends a packet >PMTU to the
client. The hop on this path with insufficient MTU will generate an
ICMPv6 Packet Too Big message back to the VIP. The LVS server receives
this message, but the call to the function handling this has been
missing. Thus, IPVS fails to forward the message to the real server,
which then does not adjust the path MTU. This patch adds the missing
call to ip_vs_in_icmp_v6() in ip_vs_in() to handle this situation.
Thanks to Rob Gallagher from HEAnet for reporting this issue and for
testing this patch in production (with direct routing mode).

This patch fixes the wrong headphone output routing for MacBookPro 3,1/4,1
quirk with ALC889A codec, which caused the silent headphone output.
Also, this gives the individual Headphone and Speaker volume controls.

In patch_vt1708(), the check of MUX nids is missing and this results in
the -EINVAL error in accessing Input Source mixer element. Simpliy
adding the call of get_mux_nids() fixes the problem.

We have a mechanism where newly registered algorithms of a higher
priority can displace existing instances that use a different
implementation of the same algorithm with a lower priority.
Unfortunately the same mechanism can cause a newly registered
algorithm to displace itself if it depends on an existing version
of the same algorithm.
This patch fixes this by keeping all algorithms that the newly
reigstered algorithm depends on, thus protecting them from being
removed.

Single line log messages should be emitted by a single call
where possible.
Converted multiple calls to DBG_PRINT to single call form.
Removed "s2io:" preface from DBG_PRINTs.
The DBG_PRINT macro now emits a log level and is surrounded by
a do {...} while (0)
All s2io log output is now prefaced with KBUILD_MODNAME ": "
via pr_fmt.
The DBG_PRINT macro should probably be converted to use the
dev_<level> form eventually.
