[PATCH] don't clear i_sb
From: Christoph Hellwig <hch@lst.de>
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..

[PATCH] ia32 sched_clock() deadlock fix
From: Ingo Molnar <mingo@elte.hu>,
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.

[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
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.

[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 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.

Patch from: Amit Gurdasani
I have a PROLiNK 1456VH internal Rockwell-based ISA PnP K56flex fax modem

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.

ia64: Fix a ptrace-bug that caused "strace -f" to crash the inferior
process. The root-cause of the problem was that ptrace() tried
to copy the portion of the register backing store that landed on
the kernel stack back to users-space, but the resulting state
was inconsistent if the inferior process was in the middle of a
system-call (as would always be the case for strace).
The solution is to avoid all needless copying and to instead
ensure that when accessing a memory location that may belong to
a thread's register-backing store, we attach to that particular
thread, rather than the thread identified by the PID argument.
If the thread happens to be unattachable, we fall back to using
the thread identified by the PID argument. This should have the
desired effect if the thread has terminated already and if the
thread is running while ptrace() is trying to access its state,
all bets are off anyhow and there are no coherency guarantees.
In other words, this should be doing the right thing under all
circumstances.
The patch also fixes the case where PT_AR_BSP and/or PT_CFM are
written while the inferior process is in the middle of a system
call. This makes arguments passed to GDB inferior calls come
out right.
The patch was tested with strace -f and the GDB testsuite, which
showed no regressions compared to the previous version of the
kernel.

[PATCH] call_usermodehelper retval fix
The reworked firmware loader in the DVB patches needs the fix to the
call_usermodehelper() return value.
From: Rusty Russell <rusty@rustcorp.com.au>
MODULE_ALIAS_BLOCK() and MODULE_ALIAS_CHAR() define aliases of form
"XXX-<major>-<minor>", so we should probe for modules using this form.
Unfortunately in 2.4, block aliases were "XXX-<major>" and char aliases
were of both forms.
Ideally, all modules would now be using MODULE_ALIAS() macros to define
their aliases, and the old configuration files wouldn't matter as much.
Unfortunately, this hasn't happened, so we make request_module() return the
exit status of modprobe, and then do fallback when probing for char and
block devices.
