[PATCH] kNFSd: Be more careful with readlock in exp_parent
We currently hold a read_lock of dparent_lock
while calling exp_get_by_name on several ancestors
of a given dentry. However exp_get_by_name can
malloc(GFP_KERNEL), so that isn't a good idea.
Now we only claim the lock while actually
stepping up the parent chain.
Except for dev_node_t, the contents of include/pcmcia/driver_ops.h
aren't used anywhere within the kernel. It's a left-over file from the
days when cardbus 32-bit cards weren't handled as pci devices, and
their drivers as pci drivers. So, move the dev_node_t to
include/pcmcia/ds.h, remove the lone in-kernel reference to
driver_ops.h, and remove the contents of driver_ops.h.
[PCMCIA] remove "init_status" from struct pcmcia_driver
As we don't have a late_initcall in ds.c any more, we can't easily
distinguish between in-kernel drivers and those built as modules. This
information was used by cardmgr to detect whether "rmmod" makes
sense. As unloading of modules seems to be deprecated behaviour anyway
in 2.5., and the current driver unloading process is IMO broken
anyway, I don't shed any tears on this lost functionality.
Previously, "Driver Services" could only be called when the socket
drivers were initialized earlier. This caused an awful lot of
problems, especially when modprobe tried to load ds.ko and a pcmcia
card driver at once.
As all socket devices are registered with the driver model core as
being of "class_type pcmcia_socket_class", we can take use of that and
register them with "Driver Services" upon detection or upon
module loading of ds.c.
Also, the "I-need-two-initcalls-in-a-module"-tweak can go away.
Unfortunately, this patch reportedly breaks some RedHat pcmcia init
scritps - they relied on the failed loading of ds.c to detect that no
socket driver was loaded previously. To properly detect this, you
should take a look at the /sys/class/pcmcia_socket/devices directory.

[XFS] Add back the pagebuf flag for scheduling on the data daemon. Moving
this into just a pagebuf_iodone parameter was broken as we don't have
sufficient state in all the places we need it to make the decision.
[XFS] Separate the quota source into its own subdirectory ala dmapi.
Push a bunch of quota- and dmapi-specific code down into these
subdirs which previously was compiled into the core XFS code,
and don't descend into these subdirs if options config'd off.

[ARM] Fix ARM do_div() implementation
The ARM do_div() implementation was rather lax in that it only

providing a 64-bit by 32-bit division in asm.
This is necessary for posix-timers to function correctly.

OK, as the consensus seems to be that in the short run changing things
for a full reset implementation is not worth it, here's an implementation
that does the best we can do without.
It issues a reset only if we can be sure that there are no other users
of the device in question.
As the version currently in the storage driver is broken anyway,
this is a definite improvement. And it addresses the need of exporting
the probe/remove functions for storage's sake.

[PATCH] x86-64 updates
Lots of x86-64 updates. Merge with 2.4 and NUMA works now. Also reenabled
the preemptive kernel. And some other bug fixes.
IOMMU disabled by default now because it has problems.
- Add more CONFIG options for device driver debugging and iommu
force/debug. (don't enable iommu force currently)
- Some S3/ACPI fixes/cleanups from Pavel.
- Set MSG_COMPAT_* in msg_flags for networking 32bit emulation.
This unfortunately still doesn't fix the fd passing problems.
- Sync PCI IOMMU code with 2.4 (minor fixes, flush less often)
- Really fix UP compilation (Pavel)
- Reenable preempt
- Fix CONFIG_DISCONTIGMEM bootup and enable. Still needs more tuning.
- Fix some bugs in topology discovery and clean code up.
- Don't put unwind tables into object files
- Some kernel debugging hooks
- Move CPU detection into early real mode code to better interact with
vesafb consoles
- Initialize mode in real mode character output
- New 32bit FPU signal save/restore
- Various fixes in FPU handling in ptrace
- Fix security holes in ptrace (32bit and 64bit)
- Fix serial ioctl (including security hole)
- Add bluetooth ioctls to 32bit emu (from sparc64)
- Correctly enable si_val in queued signals in 32bit emulation
- Rework SEM_STAT emulation. LTP still fails unfortunately.
- Fix error case in msg* emulation
- Fix debug register access from ptrace (Michal Ludvig, me)
- Fix handling of NULL arguments in 32bit execve
- Fix some error cases for 32bit readv/writev (LTP still complains)
- Remove rate control from unimplemented syscall warnings
- Fix error message for missing aperture
- Turn some APIC printks into Dprintk to make the bootup more quiet
- Some fixes for no APIC (probably still broken), add disableapic
option (untested)
- Sync K8 MCE handler with 2.4. Should work a lot better now.
- Remove never used KDB hooks
- Fix buffer overflow in command line copying
- Merge from i386: use separate status word for lazy FPU state
- Don't force the IOMMU for dma masks < 4GB.
- Print backtrace in Sysrq-T (from Andrea)
- Merge from i386: fix FPU race in fork.
- Disable NX mode by default for now
- Rewrite dump_pagetable
- Fix off by one bug in ioremap (i386 merge)
- Merge from i386: handle VIA pci bridge bugs
