If an array with 1.x metadata is assembled with the last disk missing,
md doesn't properly record the fact that the disk was missing.
This is unlikely to cause a real problem as the event count will be
different to the count on the missing disk so it won't be included in
the array. However it could still cause confusion.
So make sure we clear all the relevant slots, not just the early ones.

Now that we depend on md_update_sb to clear variable bits in
mddev->flags (rather than trying not to set them) it is important to
always call md_update_sb when appropriate.
md_check_recovery has this job but explicitly avoids it for ->external
metadata arrays. This is not longer appropraite, or needed.
However we do want to avoid taking the mddev lock if only
MD_CHANGE_PENDING is set as that is not cleared by md_update_sb for
external-metadata arrays.

drivers/firewire/nosy* is a stand-alone driver that does not depend on
CONFIG_FIREWIRE. Hence let make descend into drivers/firewire/ also
if that option is off.
The stand-alone driver drivers/ieee1394/init_ohci1394_dma* will soon be
moved into drivers/firewire/ too and will require the same makefile fix.
Side effect:
As mentioned in https://bugzilla.novell.com/show_bug.cgi?id=586172#c24
this influences the order in which either firewire-ohci or ohci1394 is
going to be bound to an OHCI-1394 controller in case of a modular build
of both drivers if no modprobe blacklist entries are configured.
However, a user of such a setup cannot expect deterministic behavior
anyway. The Kconfig help and the migration guide at
ieee1394.wiki.kernel.org recommend blacklist entries when a dual
IEEE 1394 stack build is being used. (The coexistence period of the two
stacks is planned to end soon.)

The Thinkpad X100e seems to have some odd behaviour when the display is
powered off - the onboard r8169 starts generating rxfifo overflow errors.
The root cause of this has not yet been identified and may well be a
hardware design bug on the platform, but r8169 should be more resiliant to
this. This patch enables the rxfifo interrupt on 8168 devices and removes
the MAC version check in the interrupt handler, and the machine no longer
crashes when under network load while the screen turns off.

If peer uses tiny MSS (say, 75 bytes) and similarly tiny advertised
window, the SWS logic will packetize to half the MSS unnecessarily.
This causes problems with some embedded devices.
However for large MSS devices we do want to half-MSS packetize
otherwise we never get enough packets into the pipe for things
like fast retransmit and recovery to work.
Be careful also to handle the case where MSS > window, otherwise
we'll never send until the probe timer.

Rather than just using pt_regs, it now contains the actual saved
state explicitly, similar to pt_regs. By doing it this way, we
provide a cleaner API for userspace (or equivalently, we avoid the
need for libc to provide its own definition of sigcontext).
While we're at it, move PT_FLAGS_xxx to where they are not visible
from userspace. And always pass siginfo and mcontext to signal
handlers, even if they claim they don't need it, since sometimes
they actually try to use it anyway in practice.

The texture base address registers are in units of 256 bytes.
The original CS checker treated these offsets as bytes, so the
original check was wrong. I fixed the units in a patch during
the 2.6.36 cycle, but this ended up breaking some existing
userspace (probably due to a bug in either userspace texture allocation
or the drm texture mipmap checker). So for now, until we come
up with a better fix, just warn if the mipmap size it too large.
This will keep existing userspace working and it should be just
as safe as before when we were checking the wrong units. These
are GPU MC addresses, so if they fall outside of the VRAM or
GART apertures, they end up at the GPU default page, so this should
be safe from a security perspective.
v2: Just disable the warning. It just spams the log and there's
nothing the user can do about it.
