[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.

Getting rid of sloppy logics:

a) in do_follow_link() we have the wrong vfsmount dropped if our symlink
had been mounted on something.  Currently it worls only because we never
get such situation (modulo filesystem playing dirty tricks on us).  And
it obfuscates already convoluted logics...

b) same goes for open_namei().

c) in __link_path_walk() we have another "it should never happen" sloppiness -
out_dput: there does double-free on underlying vfsmount and leaks the covering
one if we hit it just after crossing a mountpoint.  Again, wrong vfsmount
getting dropped.

d) another too-early-mntput() race - in do_follow_mount() we need to postpone
conditional mntput(path->mnt) until after dput(path->dentry).  Again, this one

[PATCH] s390: uml ptrace fixes

To make UML build and run on s390, I needed to do these two little
changes:

1) UML includes some of the subarch's (s390) headers. I had to
   change one of them with the following one-liner, to make this
   compile. AFAICS, this change doesn't break compilation of s390
   itself.

2) UML needs to intercept syscalls via ptrace to invalidate the syscall,
   read syscall's parameters and write the result with the result of
   UML's syscall processing. Also, UML needs to make sure, that the host
   does no syscall restart processing. On i386 for example, this can be
   done by writing -1 to orig_eax on the 2nd syscall interception
   (orig_eax is the syscall number, which after the interception is used
   as a "interrupt was a syscall" flag only.
   Unfortunately, s390 holds syscall number and syscall result in gpr2 and
   its "interrupt was a syscall" flag (trap) is unreachable via ptrace.
   So I changed the host to set trap to -1, if the syscall number is changed
   to an invalid value on the first syscall interception.

[PATCH] ARM: 2700/1: Disable IXP2000 IRQs at bootup

Patch from Deepak Saxena

The IXDP2800 bootloader does not disable IRQs before jumping into
the kernel and this is causing the Grand Unified KGDB to crash
the system when we do an early call to trap_init() and irq handlers
have not yet been registered. This patch disables IRQs before we
jump into the kernel.

Problem:
When a module requests a DMA channel via the function s3c2410_dma_request(), this function requests the appropriate irq under the name of the client module. When the client module is unloaded, it calls s3c2410_dma_free() which does not free the irq. Consequently, when e.g. running "cat /proc/interrupts", the irq owner points to freed memory, leading to a kernel oops.

[NET]: Fix HH_DATA_OFF.

When the hardware header size is a multiple of HH_DATA_MOD, HH_DATA_OFF()
incorrectly returns HH_DATA_MOD (instead of 0). This affects ieee80211 layer
as 802.11 header is 32 bytes long.

[NET]: Fix locking in shaper driver.

 o use a semaphore instead of an opencoded and racy lock
 o move locking out of shaper_kick and into the callers - most just
   released the lock before calling shaper_kick
 o remove in_interrupt() tests.  from ->close we can always block, from
   ->hard_start_xmit and timer context never

[PATCH] ppc64: remove decr_overclock

Now that we have HZ=1000 there is much less of a need for decr_overclock.
Remove it.

Leave spread_lpevents but move it into iSeries_setup.c.  We should look at
making event spreading the default some day.
