The parsing of some kernel parameters seem to enable irq's at a stage that
irq's are not supposed to be enabled (Particularly the ide kernel parameters).

Having irq's enabled before the irq controller is initialized might lead to a
kernel panic.  This patch only detects this behaviour and warns about wich
parameter caused it.

The calls made by parse_parms to other initialization code might enable
interrupts again way too early.

Having interrupts on this early can make systems PANIC when they initialize
the IRQ controllers (which happens later in the code).  This patch detects
that irq's are enabled again, barfs about it and disables them again as a
safety net.

Jeffrey Altman, one of the gatekeepers of OpenAFS (the open source project
which inherited the Transarc/IBM AFS codebase) has requested that the magic
number 0x5346414F (little endian 'OAFS') be allocated for the f_type field
of the fsinfo structure on Linux:

  https://lists.openafs.org/pipermail/openafs-info/2006-December/024829.html

Add it to include/linux/magic.h, mostly as a way of publishing this number
and ensuring that no other filesystem accidentally uses it.

MII_ADVERTISE and weren't testing in LPA for all PHYs).

Note that I currently only advertise pause, not asymetric pause. I

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.
