ath9k: Test for TID only in BlockAcks while checking tx status

The ath9k xmit functions for AMPDUs can send frames as non-aggregate in case
only one frame is currently available. The client will then answer using a
normal Ack instead of a BlockAck. This acknowledgement has no TID stored and
therefore the hardware is not able to provide us the corresponding TID.

The TID set by the hardware in the tx status descriptor has to be seen as
undefined and not as a valid TID value for normal acknowledgements. Doing
otherwise results in a massive amount of retransmissions and stalls of
connections.

Users may experience low bandwidth and complete connection stalls in

brcmfmac: fix end of loop check (signedness bug)

The problem here is that we loop until "remained_buf_len" is less than
zero, but since it is unsigned, it never is.

"remained_buf_len" has to be large enough to hold the value from
"mgmt_ie_buf_len".  That variable is type u32, but it only holds small
values so I have changed to both variables to int.

Also I removed the bogus initialization from "mgmt_ie_buf_len" so that
GCC can detect if it is used unitialized.  I moved the declaration of
"remained_buf_len" closer to where it is used so it's easier to read.

     up: stuff in __KERNEL__ guards stays where it is and stuff outside moves

As suggested by Andrew Morton:

  This is a pet peeve of mine.  Any time there's a long list of items
  (header file inclusions, kconfig entries, array initalisers, etc) and
  someone wants to add a new item, they *always* go and stick it at the
  end of the list.

  Guys, don't do this.  Either put the new item into a randomly-chosen
  position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically.  This commit was
created by the following perl:

while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
  /^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)
