Changing the sysctl net.core.dev_weight has no effect because the weight
of the backlog devices is set during initialization and never changed.
This patch propagates any changes to the global value affected by sysctl
to the per-cpu devices. It is done every time the packet handler
function is run.

Some bits of the kernel assume that gp always points to valid memory,
in particular PHYSICAL_MODE_ENTER() assumes that both gp and sp are
valid virtual addresses with associated physical pages. The IA64
module loader puts gp well past the end of the module, with no physical
backing. Offsets on gp are still valid, but physical mode addressing
breaks for modules. Ensure that gp always falls within the module
body. Also ensure that gp is 8 byte aligned.

We should never apply a lookup intent to anything other than the last
path component in an open(), create() or access() call.
Introduce the helper nfs_lookup_check_intent() which always returns
zero if LOOKUP_CONTINUE or LOOKUP_PARENT are set, and returns the
intent flags if we're on the last component of the lookup.
By doing so, we fix a bug in open(O_EXCL), where we may end up
optimizing away a real lookup of the parent directory.

[AGPGART] Replace check_bridge_mode() with (bridge->mode & AGSTAT_MODE_3_0).
As mentioned earlier, the current check_bridge_mode() code assumes
that AGP bridges are PCI devices. This isn't always true. Definitely
not for HP zx1 chipset and the same seems to be the case for SGI's AGP
bridge.
The patch below fixes the problem by picking up the AGP_MODE_3_0 bit
from bridge->mode. I feel like I may be missing something, since I
can't see any reason why check_bridge_mode() wasn't doing that in the
first place. According to the AGP 3.0 specs, the AGP_MODE_3_0 bit is
determined during the hardware reset and cannot be changed, so it
seems to me it should be safe to pick it up from bridge->mode.
With the patch applied, I can definitely use AGP acceleration both
with AGP 2.0 and AGP 3.0 (one with an Nvidia card, the other with an
ATI FireGL card).
Unless someone spots a problem, please apply this patch so 3d
acceleration can work on zx1 boxes again.
This makes AGP work again on machines with an AGP bridge that isn't a
PCI device.

When Linux is running on the Xen virtual machine monitor, physical
addresses are virtualised and cannot be directly referenced by the AGP
GART. This patch fixes the GART driver for Xen by adding a layer of
abstraction between physical addresses and 'GART addresses'.
Architecture-specific functions are also defined for allocating and freeing
the GATT. Xen requires this to ensure that table really is contiguous from
the point of view of the GART.
These extra interface functions are defined as 'no-ops' for all existing
architectures that use the GART driver.

On some 5701 devices with older bootcode, the LED configuration bits in
SRAM may be invalid with value zero. The fix is to check for invalid
bits (0) and default to PHY 1 mode. Incorrect LED mode will lead to
error in programming the PHY.
Thanks to Grant Grundler for debugging the problem.
>From Grant:
| In May, 2004, tg3 v3.4 changed how MAC_LED_CTRL (0x40c) was getting
| programmed and how to determine what to program into LED_CTRL. The new
| code trusted NIC_SRAM_DATA_CFG (0x00000b58) to indicate what to write
