intelfbhw_get_p1p2 is used only if REGDUMP is defined - compile it in only
if REGDUMP is defined - one less compiler warning.

According to drivers/video/intelfb/intelfb.h, the intelfb driver
supportes the following devices:
830M/845G/852GM/855GM/865G/915G/915GM/945G/945GM. So the description in
drivers/video/Kconfig and the documentation in
Documentation/fb/intelfb.txt is outdated.

[05/05] intelfb: Honor FB_ACTIVATE_VBL for display panning
Extends the intelfb_vsync struct to store panning offset. The interrupt service routine uses the stored panning offset if a pan is requested for the vsync. intelfbhw_disable_irq also pans the display if there is a pending request.

[04/05] intelfb: implement FBIO_WAITFORVSYNC ioctl
The (unofficial) FBIO_WAITFORVSYNC ioctl is implemented by sleeping on the appropriate waitqueue, as defined in my earlier patch. Currently, only display 0 (aka pipe A) is supported.

[03/05] intelfb: Implement basic interrupt handling
Functions have been added to enable and disable interrupts using the MMIO registers. Currently only pipe A vsync interrupts are enabled.
A generalized vsync accounting struct is defined, with the intent that it can encapsulate per-pipe vsync related info in the future. Currently a single instance is hard-coded.
The interrupt service routine currently only looks for vsync interrupts on pipe A, and increments a counter and wakes up anyone waiting on it.
This implementation is heavily influenced by similar implementations in the atyfb and matroxfb drivers.

[AK: This apparently broke some systems, but we need it to fix
a compile problem with old binutils and in theory the patch
is correct. So let's trying reenabling it again.]
o Currently bss segment is being placed somewhere in the middle (after .data)
section and after bss lots of init section and data sections are coming.
Is it intentional?
o One side affect of placing bss in the middle is that objcopy keeps the
bss in raw binary image (vmlinux.bin) hence unnecessarily increasing
the size of raw binary image. (In my case ~600K). It also increases
the size of generated bzImage, though the increase is very small
(896 bytes), probably a very high compression ratio for stream
of zeros.
o This patch moves the bss at the end hence reducing the size of
bzImage by 896 bytes and size of vmlinux.bin by 600K.
o This change benefits in the context of relocatable kernel patches. If
kernel bss is not part of compressed data (vmlinux.bin) then it does
not have to be decompressed and this area can be used by the decompressor
for its execution hence keeping the memory requirements bounded and
decompressor code does not stomp over any other data loaded beyond
kernel image (As might be the case with bootloaders like kexec).

We only need the timestamp on COOKIE-ECHO chunks, so instead of always
timestamping every SCTP packet, let common code timestamp if the socket
option is set. For COOKIE-ECHO, simply get the time of day if we don't
have a timestamp. This introduces a small possibility that the cookie
may be considered expired, but it will be renegotiated.

Currently if the sender is sending small messages, it can cause a receiver
to run out of receive buffer space even when the advertised receive window
is still open and results in packet drops and retransmissions. Including
a overhead while updating the sender's view of peer receive window will
reduce the chances of receive buffer space overshooting the receive window.

MSI is defined to be 32-bit write. The 5706 does 64-bit MSI writes
with byte enables disabled on the unused 32-bit word. This is legal
but causes problems on the AMD 8132 which will eventually stop
responding after a while.
Without this patch, the MSI test done by the driver during open will
pass, but MSI will eventually stop working after a few MSIs are
written by the device.
AMD believes this incompatibility is unique to the 5706, and
prefers to locally disable MSI rather than globally disabling it
using pci_msi_quirk.
Update version to 1.4.45.
