When booting Linux on a txx9 board with VxWorks boot loader, it crashes in
prom_getenv(), as VxWorks doesn't pass firmware parameters in a0-a3 (in my
case, the actual leftover values in these registers were 0x80002000,
0x80001fe0, 0x2000, and 0x20).
Make the parsing of argc, argv, and envp a bit more robust by checking if
argc is a number below CKSEG0, and argv/envp point to CKSEG0.

In commit f337b9c583 ("epoll: drop
unnecessary test") Thomas found that there is an unnecessary (always
true) test in ep_send_events(). The callback never inserts into
->rdllink while the send loop is performed, and also does the
~EP_PRIVATE_BITS test. Given we're holding the mutex during this time,
the conditions tested inside the loop are always true.
HOWEVER.
The test "!ep_is_linked(&epi->rdllink)" wasn't there because we insert
into ->rdllink, but because the send-events loop might terminate before
the whole list is scanned (-EFAULT).
In such cases, when the loop terminates early, and when a (leftover)
file received an event while we're performing the lockless loop, we need
such test to avoid to double insert the epoll items. The list_splice()
done a few steps below, will correctly re-insert the ones that were left
on "txlist".
This should fix the kenrel.org bugzilla entry 11831.

Some userland apps seem to pass in a "0" for the seconds, and several
seconds worth of usecs to select(). The old kernels accepted this just
fine, so the new kernels must too.
However, due to the upscaling of the microseconds to nanoseconds we had
some cases where we got math overflow, and depending on the GCC version
(due to inlining decisions) that actually resulted in an -EINVAL return.
This patch fixes this by adding the excess microseconds to the seconds
field.
Also with thanks to Marcin Slusarz for spotting some implementation bugs
in the diagnostics patches.

The default for the regulatory compatibility option is wrong;
if you picked the default you ended up with a non-functional wifi
system (at least I did on Fedora 9 with iwl4965).
I don't think even the October 2008 releases of the various distros
has the new userland so clearly the default is wrong, and also
we can't just go about deleting this in 2.6.29...
Change the default to "y" and also adjust the config text a little to
reflect this.

This reverts commit 7bf6bf4803.
The code has both a short existence and an increasing track of failures
despite some work to amend it for -rc1. It is not just a matter of
reading the eeprom: sometimes the eeprom is read correctly, then the mac
address is not written correctly back into the mac registers.
Some chipsets seem to work reliably but it is not clear at this point if
the code can simply be made to work on a per-chipset basis and post -rc1
is not the place where I want to experiment these things.
