Fix two N_TTY line discipline issues related to resuming a stopped TTY
(typically done with ctrl-S):
1) Fix handling of character that resumes a stopped TTY (with IXANY)
With "stty ixany", the TTY line discipline would lose the first character
after the stop, so typing, for example, "hi^Sthere" resulted in "hihere"
(the 't' would cause the resume after ^S, but it would then be thrown away
rather than processed as an input character). This was inconsistent with
the behavior of other Unix systems.
2) Fix interrupt signal (e.g. ctrl-C) behavior in stopped TTYs
With "stty -ixany" (often the default), interrupt signals were ignored
in a stopped TTY until the TTY was resumed with the start char (typically
ctrl-Q), which was inconsistent with the behavior of other Unix systems.

Turn on INTR/QUIT/SUSP echoing in the N_TTY line discipline (e.g. ctrl-C
will appear as "^C" if stty echoctl is set and ctrl-C is set as INTR).
Linux seems to be the only unix-like OS (recently I've verified this on
Solaris, BSD, and Mac OS X) that does *not* behave this way, and I really
miss this as a good visual confirmation of the interrupt of a program in
the console or xterm. I remember this fondly from many Unixs I've used
over the years as well. Bringing this to Linux also seems like a good way
to make it yet more compliant with standard unix-like behavior.

The clean up procedure now uses platform device "release" callback to
handle memory clean up. For this purpose "release" function callback was
added to struct tpm_vendor_specific, so hw device driver provider can get
called when it is safe to remove all allocated resources.
This is supposed to fix a bug in device removal, where device while in
receive function (waiting on timeout) was prone to segfault, if the
tpm_chip struct was unallocated before the timeout expired (in
tpm_remove_hardware).

After analyzing the elements that save_flags/cli/sti/restore_flags were
protecting, convert their usages to a global spinlock (the easiest and
most obvious next-step). There were some usages of flags being
intentionally cached, because the code already knew the state of
interrupts. These have been taken into account.
This allows us to remove CONFIG_BROKEN_ON_SMP. Completely untested.

Convert the io_req_t members to unsigned int, to allow use on machines with
more than 16 bits worth of IO ports (i.e. secondary busses on ppc64, etc).
There was only a couple of places in drivers where a change was needed. I
left printk formats alone (there are lots of %04x-style formats in there),
mostly to not change the format on the platforms that only have 16-bit io
addresses, but also because the padding doesn't really add all that much value
most of the time.
I found only one sprintf of an address, and upsized the string accordingly (I
doubt anyone will have anywhere near INT_MAX as irq value, but at least
there's room for it now).

This adds support for flushing the chipsets on the 915, 945, 965 and G33
families of Intel chips.
The BIOS doesn't seem to always allocate the BAR on the 965 chipsets
so I have to use pci resource code to create a resource
It adds an export for pcibios_align_resource.
This bumps the AGP interface to 0.103.
Certain Intel chipsets contains a global write buffer, and this can require
flushing from the drm or X.org to make sure all data has hit RAM before
initiating a GPU transfer, due to a lack of coherency with the integrated
graphics device and this buffer.
This just adds generic support to the AGP interfaces, a follow-on patch
will add support to the Intel driver to use this interface.
