[XFS] Rename pagebuf debug option (ie. pagebuf tracing) into a generic XFS tracing option for the other XFS trace code to use too (once fixed).

SGI Modid: 2.5.x-xfs:slinx:159717a

dropping it cuts down on merge noise.  Simplifies the Makefile too.

JFS currently clears i_sb in some error pathes which can make the
core kernel OOPS because it may never be NULL.  Noticed because some
IBM people try to "fix" the core kernel for it now..

Voyager is getting odd deadlocks due to the taking of xtime_lock() in
sched_clock()->get_jiffies_64().

I had this patch queued up to fix a different deadlock, which occurs when we
relax the requirement that TSC's be synchronised across CPUs.  But it will
fix James' deadlock too.

- move around sp887x firmware file entry to be close to sp887x selection

- fix a bunch of filenames to point to /usr/lib/hotplug/firmware/ rather
  then /etc/dvb

- fix the av7110 firmware config entry for "make allyesconfig"

After Jose debugged the problem down to the routine jfs_get_parent, we
were able to find the problem.  I believe it only affects users of
NFS-exported JFS file systems on big-endian hardware.

The problem was a missing le32_to_cpu macro.  The patch also fixes a
return code to be more consistent other implementations of get_parent.

This fixes an oops when a kobject is unregistered before it's child is.
The usb-serial devices show this bug very easily (yank out a device
while its port is opened...)

Patch was originally written by Mike Gorse <mgorse@mgorse.dhs.org>

Add missing NR_VECTORS definition to visws and pc9800.  Also, make MSI
support dependent on CONFIG_X86_IO_APIC, as it won't build without IOAPIC
support.

Also consolidate a bunch of convoluted if's into a single
"is this an r200 or r300" function.

The recent escd fix I have made corrects a thinko in the PnPBIOS code and it
turns out that faults from calling /proc/pnp/bus/escd were probably not caused
by BIOS bugs.

Sometimes a menuconfig item is shown twice, so hide the other item.

Let gconf find it's glade file, even it's started with an absolute path
and check srcdir so it also works if it's compiled outside of the tree.

Fix for oops on rmmod caused by *_remove() function marked as __devinit
(and thus discarded after module initialization - if CONFIG_MODULES=y
and CONFIG_HOTPLUG is not set).
This patch changes __devinit to __devexit and adds __devexit_p() where
pointer to such function is used.

The only exception is au1000, where au1000_remove() is called from
cleanup_au1000() function - __devinit is jest removed there.

It was also removed in 2.4.23.

Use rq->cmd[0] instead of rq->flags for storing special request flags.

Per Jens' suggestion.  Tested by Stef van der Made <svdmade@planet.nl>.

Revert wrong changes introduced in 2.4.21.

The MSI port to x86-64 added an interrupt routing bug that makes the
kernel not boot anymore on some machines.

Fix that.

sometimes nanoseconds are used, sometimes microseconds, sometimes even something else.
