NFSv4 state model update
- Hierarchy of state attached to nfs4_client in order to
simplify state recovery.
state_owners hang off nfs4_client, whereas state hangs
off both open_owners and the nfs_inode.
- Model tries to minimize the number of open_owners on
the server by recycling unused open_owners into a pool.
- NFSv4 state attached to file->private_data. Previously
this was used by credentials (and still is for NFSv2/v3)
Abstract out setup/release of struct file and nfs_page
structure initialization in order to cope with these
conflicting uses of private_data.

Simplify the synchronous NFS read call interface by
passing a pointer to a filled nfs_read_data structure
(the same struct used by the asynchronous function calls)

The NFSv4 state model assumes that the client machine identifies
itself to the server once and once only.
This patch ensures that we do this by sharing the local identifier
struct nfs4_client among all mountpoints that talk to the same
server/ip address.

Fix up hangs with the upcall mechanism for RPCSEC_GSS and the
NFSv4 idmapper.
- Correct bugs in idmapper wait code.
- Correct layering bugs in RPCSEC_GSS and idmapper
- Ensure we advance the file pointer in case of partial
reads/writes of a message on the pipes

UDP round trip timer fix. Modify Karn's algorithm so that
we inherit timeouts from previous requests.
This means that we lengthen the window of time during which
we accept updates to the RTO estimate if we see an update.
Scheme proposed by Brian Mancuso, but it is standard for TCP
congestion control implementations.

[PATCH] v4l: bttv driver update
This updates the bttv driver. It depends on the videobuf patch.
* usual tv card list updates.
* sysfs adaptions.
* new, experimental i2c adapter code for bt878 chips
(not used by default yet).
* various minor fixes.

[PATCH] v4l: videobuf update
This updates the videobuf module used by the bttv, saa7134 and saa7146
drivers.
Changes:
* adds support for overlays (i.e. PCI-PCI DMA transfers).
* adds support for userspace DMA.
* fixes bug in the read() helper function (catch I/O errors).

[PATCH] cpufreq for x86-64
Reuses the i386 cpufreq code and add an notifier to the x86-64
timer code to track frequency changes.
All previous criticism of earlier patches should be addressed:
- it doesn't touch i386 now
- Doesn't include the ACPI P states driver anymore following brodo's request.

[PATCH] UID16 fixes
This fixes CONFIG_UID16 problems on x86-64 as discussed earlier.
CONFIG_UID16 now only selects the inclusion of kernel/uid16.c, all
conversions are triggered dynamically based on type sizes. This allows
x86-64 to both include uid16.c for emulation purposes, but not truncate
uids to 16bit in sys_newstat.
- Replace the old macros from linux/highuid.h with new SET_UID/SET_GID
macros that do type checking. Based on Linus' proposal.
- Fix everybody to use them.
- Clean up some cruft in the x86-64 32bit emulation allowed by this
(other 32bit emulations could be cleaned too, but I'm too lazy for
that right now)
- Add one missing EOVERFLOW check in x86-64 32bit sys_newstat while
I was at it.
there's one call to strncpy() in vfat that really should be a memcpy().
The source, msdos_name, is a space-filled char array, not a
NUL-terminated string.
The rest of the patch eliminates duplicate occurencies of the
CURRENT_TIME macro inside functions. This shrinks vfat.o by a few
bytes.

[PATCH] Fix sysrq-t free stack output
It seems that we're attempting to work out the free stack size using two
unrelated pointers for the lowest address of the stack. Fix this to use
the correct pointer.
- Remove dynamic allocation of major numbers. Just use static major 94.
- Use bus_id instead of device number where possible.
- Don't check open_count in dasd_generic_set_offline.
