If the kernel attempts to execute a CP1 or CP2 instruction and it
aborts, and a FP emulator is not loaded, we try to return as if to
a user context, instead of the proper kernel context.  Since the
fault came from kernel mode, we must use the kernel return paths.

This patch adds support for a few more PHYs used by Apple and fixes
advertising and detecting of Pause (we were missing setting the bit in
MII_ADVERTISE and weren't testing in LPA for all PHYs).

Note that I currently only advertise pause, not asymetric pause. I
don't know for sure the details there, I suppose I should read a bit
more 802.3 references, and I don't now what sungem is capable of, but
I noticed the PCS code (originated from you) does the same.

It's a known fact that Windows times out commands after 7 seconds, so
drives generally try and respond if they can before that happens.  We
default to 5 seconds, which sometimes is a bit too short.

Jeremy Higdon reported here:

	http://lkml.org/lkml/2007/1/1/145

that his drive takes longer than 5 seconds for a "read track
information" command, later confirming that it is about 6.7 seconds.

So just do the sane thing and change the default command timeout to 7
seconds to avoid other surprises.

This is patch that solves Ebox mini PC issue and make
FSB code more specification compilant. At start guess_fsb
function is guessing 200MHz FSB too. It is better to
make it in this way because, thanks to this function, driver
will fail for bogus FSB values caused by bogus multiplier
value. For PowerSaver processors we can't depend on Max /
MinMHzFSB because these values are only used for
PowerSaver 2.0 and 3.0. Most processors on which Longhaul
is used are PowerSaver 1.0 only. I'm changing code for older
CPU's too, but not so much as previously, and this code was
already used for Ezra. Using MinMHzBR for Ezra-T is outside
spec. It is for voltage scaling purpose and don't have to
be equal to minmult (but it is). Same for Nehemiah (it
isn't for sure). Added mult - current multiplier value.

Commit 968de4f0 ("i386: Relocatable
kernel support") caused problems for people with old binutils versions
that didn't mark ".text.*" sections automatically allocated.

So we should use .section command to specifically mark .text.head
section as AX (allocatable and executable) to solve the problem.

This should be unnecessary with binutils 2.15 and later, which is
already three years old, but it doesn't hurt supporting older toolchains
where possible.
