ia64: add generic defconfig file
Here's a generic_defconfig that works on all the ia64
platforms I'm aware of, and we can always update it if it's
missing a driver or two. Compile tested 'make compressed' and
'make modules', and boot tested on sn2, and I think Alex boot
tested on an HP machine.

Fix subtle fork() race that Ingo noticed.
We must not mark the process TASK_STOPPED early, because
that might allow a signal to wake it up before we actually
got to the "wake_up_forked_process()" state. Total confusion
would happen.
Make wake_up_forked_process() verify the new world order.

[PATCH] ia32 sched_clock() deadlock fix

Voyager is getting odd deadlocks due to the taking of xtime_lock() in

relax the requirement that TSC's be synchronised across CPUs. But it will

[PATCH] JFS fix for NFS on little-endian systems
From: Dave Kleikamp <shaggy@austin.ibm.com>
After Jose debugged the problem down to the routine jfs_get_parent, we

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.

[PATCH] Fix PnP BIOS call
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.
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.
This fixes BUG-on-swapout for srmmu-based systems. The problem is
caused by kmap_atomic_to_page being fed an aliased (pagetable) address
and returning bogons. This also adjusts the pkmap and fixmap base
addresses so they cannot overlap.

ia64: Cleanup EXPORT_SYMBOL usage
This cleans up the use of EXPORT_SYMBOL in ia64_ksyms.c by
moving most of them to the place where the symbol is defined.
Ideally, only symbols defined in assembler sources should
remain here, but there are some cases where an EXPORT_SYMBOL
is missing outside the arch/ia64 tree. I did not change them
for now. Also, EXPORT_SYMBOL_NOVERS is obsolete.
This patch for 2.6 fixes the problem found by Zoltan Farkas
with mixed PCI/ISA and a non-modular config. The problem is the old_netdev
ISA probing isn't skipping eth0 which already got assigned by the PCI
initialization.

Fix IDE "PIO WRITE wait for ready" test under extreme interrupt load.
From Daniel Tram Lux: under extreme irq load on an underpowered CPU,
the timeout loop may not make any progress, and decide that a timeout
occurred before it has actually tested the status register.
The minimal fix for now is to just have a final test _after_ the timeout
to remove the problem. The real fix would likely be to not have irqs
enabled between reading the status and the timeout.
