This reverts commit

It breaks 802.3ad bonding inside of a bridge.
The commit was meant to support transport bridging, and specifically
virtual machines bridged to an ethernet interface connected to a
switch port wiht 802.1x enabled.
But this isn't the way to do it, it breaks too many other things.

inetpeer: reduce stack usage

ath9k_hw: fix stopping rx DMA during resets
During PHY errors, the MAC can sometimes fail to enter an idle state on older
hardware (before AR9380) after an rx stop has been requested.
This typically shows up in the kernel log with messages like these:
ath: Could not stop RX, we could be confusing the DMA engine when we start RX up
------------[ cut here ]------------
WARNING: at drivers/net/wireless/ath/ath9k/recv.c:504 ath_stoprecv+0xcc/0xf0 [ath9k]()

When this happens, the state that the MAC enters is easy to identify and
does not result in bogus DMA traffic, however to ensure a working state
after a channel change, the hardware should still be reset.
This patch adds detection for this specific MAC state, after which the above
warnings completely disappear in my tests.

sfc: Do not use efx_process_channel_now() in online self-test
During self-tests we use efx_process_channel_now() to handle
completion and other events synchronously. This disables interrupts
and NAPI processing for the channel in question, but it may still be
interrupted by another channel. A single socket may receive packets
from multiple net devices or even multiple channels of the same net
device, so this can result in deadlock on a socket lock.
Receiving packets in process context will also result in incorrect
classification by the network cgroup classifier.
Therefore, we must only use efx_process_channel_now() in the offline
loopback tests (which never deliver packets up the stack) and not for
the online interrupt and event tests.
For the interrupt test, there is no reason to process events. We
only care that an interrupt is raised.
For the event test, we want to know whether events have been received,
and there may be many events ahead of the one we inject. Therefore
remove efx_channel::magic_count and instead test whether
efx_channel::eventq_read_ptr advances. This is currently an event
queue index and might wrap around to exactly the same value, resulting
in a false negative. Therefore move the masking to efx_event() and
efx_nic_eventq_read_ack() so that it cannot wrap within the time of
the test.
The event test also tries to diagnose failures by checking whether an
event was delivered without causing an interrupt. Add and use a
helper function that only does this.

> ath: invalid regulatory domain/country code 0x5c

It turned out that the regdomain 'APL7_FCCA' was not mapped yet.
According to Luis R. Rodriguez [Atheros' engineer] APL7 maps to
FCC_CTL and FCCA maps to FCC_CTL as well, so the attached patch
should be correct.

mm: avoid wrapping vm_pgoff in mremap()
The normal mmap paths all avoid creating a mapping where the pgoff
inside the mapping could wrap around due to overflow. However, an
expanding mremap() can take such a non-wrapping mapping and make it
bigger and cause a wrapping condition.
Noticed by Robert Swiecki when running a system call fuzzer, where it
caused a BUG_ON() due to terminally confusing the vma_prio_tree code. A
vma dumping patch by Hugh then pinpointed the crazy wrapped case.

ALSA: hda - HDMI: Fix MCP7x audio infoframe checksums
The MCP7x hardware computes the audio infoframe channel count
automatically, but requires the audio driver to set the audio
infoframe checksum manually via the Nv_VERB_SET_Info_Frame_Checksum
control verb.
When audio starts playing, nvhdmi_8ch_7x_pcm_prepare sets the checksum
to (0x71 - chan - chanmask). For example, for 2ch audio, chan == 1
and chanmask == 0 so the checksum is set to 0x70. When audio playback
finishes and the device is closed, nvhdmi_8ch_7x_pcm_close resets the
channel formats, causing the channel count to revert to 8ch. Since
the checksum is not reset, the hardware starts generating audio
infoframes with invalid checksums. This causes some displays to blank
the video.
Fix this by updating the checksum and channel mask when the device is
closed and also when it is first initialized. In addition, make sure
that the channel mask is appropriate for an 8ch infoframe by setting
it to 0x13 (FL FR LFE FC RL RR RLC RRC).

Commit
f44f7f96a20 ("RTC: Initialize kernel state from RTC") caused a
boot regression on the MRST platform.
The reason is that rtc_device_register() calls rtc_read_alarm() after
that change, which function does not have all driver data set up yet.
The rtc-mrst driver needs to call dev_set_drvdata() before rtc_device_register()
gets called.
