From Manfred Spraul

Always enable the cpu arrays, even on uniprocessor.

They provide LIFO ordering, which should improve cache hit rates.  And
the array allocator is slightly faster than the list operations.

From Manfred Spraul

remove kmem_ from all static function that are only used in slab.c.
Except kmem_cache_slabmgmt, I've renamed it to alloc_slabmgmt().

add_timer_on is like add_timer, except it takes a target CPU on which
to add the timer.

The slab code needs per-cpu timers for shrinking the per-cpu caches.

Patch from Dipankar Sarma  <dipankar@in.ibm.com>

This is Manfred's patch which provides a CPU_UP_PREPARE cpu notifier to
allow initialization of per_cpu data just before the cpu becomes fully
functional.

It also provides a facility for the CPU_UP_PREPARE handler to return
NOTIFY_BAD to signify that the CPU is not permitted to come up.  If
that happens, a CPU_UP_CANCELLED message is passed to all the handlers.

The patch also fixes a bogus NOFITY_BAD return from the softirq setup
code.

Patch has been acked by Rusty.

We need this mechanism in slab for starting per-cpu timers and for
allocating the per-cpu slab hgead arrays *before* the CPU has come up
and started using slab.

 - Remove obsolete documentation
 - Update arch/parisc/lib
 - Remove arch/parisc/tools, we use asm-offsets.c these days
 - Update arch/parisc/Makefile, defconfig & vmlinux.lds.S

Add support for the parisc64 architecture.

Performance monitor support for PA8000+ processors.

Update arch/parisc/kernel.

Update arch/parisc/mm

Update include/asm-parisc

Add support for unimplemented FP ops on PA processors.

This patch adds some new events to the sonypi driver (Fn key
pressed alone, jogdial turned fast or very fast) and cleanups
the code a little bit.

Thanks to Christian Gennerat for this contribution.

Latest version of the epoll interfaces.

struct subsystem may now contain a pointer to a NULL-terminated array of 
default attributes to be exported when an object is registered with the subsystem.
kobject registration will check the return values of the directory creation and 
the creation of each file, and handle it appropriately. 

The documentation has also been updated.

Previously, sysfs read() and write() calls looked for sysfs_ops in the struct 
sysfs_dir, in the kobject. Since objects belong to a subsystem, and is a member
of a group of like devices, the sysfs_ops have been moved to struct subsystem,
and are referenced from there.

The only remaining member of struct sysfs_dir is the dentry of the object's 
directory. That is moved out of the dir struct and directly into struct kobject.
That saves us 4 bytes/object.

All of the sysfs functions that referenced the struct have been changed to just
reference the dentry.

This fixes "choice" behaviour - it sets the correct default and fixes
oldconfig.

A struct subsystem is basically a collection of objects of a certain type,
and some callbacks to operate on objects of that type. 

subsystems contain embedded kobjects themselves, and have a similar set of 
library routines that kobjects do, which are mostly just wrappers for the
correlating kobject routines. 

kobjects are inserted in depth-first order into their subsystem's list of 
objects. Orphan kobjects are also given foster parents that point to their
subsystem. This provides a bit more rigidity in the hierarchy, and disallows
any orphan kobjects.

When an object is unregistered, it is removed from its subsystem's list. When
the objects' refcount hits 0, the subsystem's ->release() callback is called. 

Documentation describing the objects and the interfaces has also been added.

Add new configs to match changes done lately.

into home.transmeta.com:/home/torvalds/v2.5/kconfig

If we are to build menuconfig/xconfig, we may not have a .config
yet, so we shouldn't try to include it.

Set MODVERDIR before including the subdir Makefile, drivers/scsi/53c700
needs it.

Got it.  Breakage happened when Jens was switching to partial
completions - !uptodate is not quite the same as !err ;-)

With this fixed everything seems to work nicely.

It's now

int sysfs_create_link(struct kobject * kobj, struct kobject * target, char * name)

So, the caller doesn't have to determine the path of the target nor the depth of
the object we're creating the symlink for; it's all taken care of.

This mentions the web page with information about how to use
the 'usbtest' driver.

This is a version of a patch I sent out last Friday to help
address some of the "bad entry" errors that some folk
were seeing, seemingly only with control requests.  The fix
is just to not try being clever: remove one TD at a time and
patch the ED as if that TD had completed normally, then do
the next ... don't try to patch just once in this fault case.
(And it nukes some debug info I accidently submitted.)

I've gotten preliminary feedback that this helps.
