The reason is a problem with asynchronous vs. synchronous
commands, what happens here is the following:
* TE 0x2601 is removed, the TIME_EVENT_CMD for that is async
* a new TE (will be 0x2701) is created, the TIME_EVENT_CMD
for that is sync and also uses a notification wait for the
response (to avoid another race condition)
* the response for the TE 0x2601 removal comes from the
firmware, and is handled by the notification wait handler
that's really waiting for the second response, but can't
tell the difference, we therefore see the message
"TIME_EVENT_CMD response - UID = 0x2601" instead of
"TIME_EVENT_CMD response - UID = 0x2701".
Fix this issue by making the TE removal synchronous as well,
this means that we wait for the response to that command
first, before there's any chance of sending a new one.
Also, to detect such issues more easily in the future, add
a warning to the notification handler that detects them.

The patch adds proper error handling in all the cases.
Also it moves free_irq() from mxser_release_ISA_res() to mxser_board_remove(),
since it makes mxser_release_ISA_res() a counterpart for mxser_get_ISA_conf(),

For Velleman K8055 (aka VM110), `vmk80xx_read_packet()` and
`vmk8055_write_packet()` send an URB asynchronously and do not wait for
it complete. However, callers of `vmk80xx_read_packet()` are assuming
the contents of the data buffer `devpriv->usb_rx_buf` are valid
immediately after that function returns.
For Velleman K8061 (aka VM140), `vmk80xx_read_packet()` and
`vmk80xx_write_packet()` punt the requests to `vmk80xx_do_bulk_msg()`
which *does* wait for the URBs to complete (albeit with no error
checking!).
Change `vmk80xx_read_packet()` and `vmk80xx_write_packet()` to use
`usb_interrupt_msg()` for the K8055, so the callers of
`vmk80xx_read_packet()` can assume the data buffer contents are valid
(if no error occurred). Remove all the code for checking for transfers
in progress and busy waiting, as it's no longer needed. Pretty much all
the callers of `vmk80xx_read_packet()` and `vmk80xx_write_packet()` hold
the same semaphore anyway, and the only caller that doesn't
(`vmk80xx_reset_device()` called during initialization of the device)
doesn't really matter.

Commit c060f943d0 ("mm: use aligned zone start for pfn_to_bitidx
calculation") fixed out calculation of the index into the pageblock
bitmap when a !SPARSEMEM zome was not aligned to pageblock_nr_pages.
However, the _allocation_ of that bitmap had never taken this alignment
requirement into accout, so depending on the exact size and alignment of
the zone, the use of that index could then access past the allocation,
resulting in some very subtle memory corruption.
This was reported (and bisected) by Ingo Molnar: one of his random
config builds would hang with certain very specific kernel command line
options.
In the meantime, commit c060f943d0 has been marked for stable, so this
fix needs to be back-ported to the stable kernels that backported the
commit to use the right alignment.

====================
This series contains updates to e1000, e1000e, igb, igbvf and ixgbe.
The e1000, e1000e, igb and igbvf are single patch changes and the
remaining 11 patches are all against ixgbe.
The e1000 patch is a comment cleanup to align e1000 with the code
commenting style for /drivers/net. It also contains a few other white
space cleanups (i.e. fix lines over 80 char, remove unnecessary blank
lines and fix the use of tabs/spaces).
The e1000e patch from Koki (Fujitsu) adds a warning when link speed is
downgraded due to SmartSpeed.
The igb patch from Stefan (Red Hat) increases the timeout in the ethtool
offline self-test because some i350 adapters would sometimes fail the
self-test because link auto negotiation may take longer than the current
4 second timeout.
The igbvf patch from Alex is meant to address several race issues that
become possible because next_to_watch could possibly be set to a value
that shows that the descriptor is done when it is not. In order to correct
that we instead make next_to_watch a pointer that is set to NULL during
cleanup, and set to the eop_desc after the descriptor rings have been written.
The remaining patches for ixgbe are a mix of fixes and added support as well
as some cleanup. Most notably is the added support for displaying the
number of Tx/Rx channels via ethtool by Alex. Also Aurélien adds the
ability for reading data from SFP+ modules over i2c for diagnostic
monitoring.
