Rather than having every driver fiddle about setting its private
IRQ operations and data, provide a helper function to contain
this functionality in one place.

Arrange to remove the driver-private IRQ operations and data when
the device is removed from the driver, and remove the driver
private code to do this.

This fixes potential problems caused by drivers forgetting to
remove these hooks.

In 9d6a8c5c we changed posix_test_lock
to modify its single file_lock argument instead of taking separate input
and output arguments.  This makes it no longer safe to set the output
lock's fl_type to F_UNLCK before looking for a conflict, since that
means searching for a conflict against a lock with type F_UNLCK.

This fixes a regression which causes F_GETLK to incorrectly report no
conflict on most filesystems (including any filesystem that doesn't do
its own locking).

Also fix posix_lock_to_flock() to copy the lock type.  This isn't
strictly necessary, since the caller already does this; but it seems
less likely to cause confusion in the future.

When a raid1 has only one working drive, we want read error to propagate up
to the filesystem as there is no point failing the last drive in an array.

Currently the code perform this check is racy.  If a write and a read a
both submitted to a device on a 2-drive raid1, and the write fails followed
by the read failing, the read will see that there is only one working drive
and will pass the failure up, even though the one working drive is actually
the *other* one.

This reverts commit c9ccf30d.

Entering the kernel at startup_32 without passing our real mode data in
%esi, and without guaranteeing that physical and virtual addresses are
identity mapped makes head.S impossible to maintain.

The only user of this infrastructure is lguest which is not merged so
nothing we currently support will break by removing this over designed
nightmare, and only the pending lguest patches will be affected.  The
pending Xen patches have a different entry point that they use.

We are currently discussing what Xen and lguest need to do to boot the
kernel in a more normal fashion so using startup_32 in this weird manner is
clearly not their long term direction.

So let's remove this code in head.S before it causes brain damage to people
trying to maintain head.S

We keep on getting "right shift count >= width of type" warnings when doing
things like

	sector_t s;

	x = s >> 56;

because with CONFIG_LBD=n, s is only 32-bit.  Similar problems can occur with
dma_addr_t's.

So add a simple wrapper function which code can use to avoid this warning.
The above example would become

	x = upper_32_bits(s) >> 24;

The first user is in fact AFS.

Avoid atomic overhead in slab_alloc and slab_free

SLUB needs to use the slab_lock for the per cpu slabs to synchronize with
potential kfree operations.  This patch avoids that need by moving all free
objects onto a lockless_freelist.  The regular freelist continues to exist
and will be used to free objects.  So while we consume the
lockless_freelist the regular freelist may build up objects.

If we are out of objects on the lockless_freelist then we may check the
regular freelist.  If it has objects then we move those over to the
lockless_freelist and do this again.  There is a significant savings in
terms of atomic operations that have to be performed.

We can even free directly to the lockless_freelist if we know that we are
running on the same processor.  So this speeds up short lived objects.
They may be allocated and freed without taking the slab_lock.  This is
particular good for netperf.

In order to maximize the effect of the new faster hotpath we extract the
hottest performance pieces into inlined functions.  These are then inlined
into kmem_cache_alloc and kmem_cache_free.  So hotpath allocation and
freeing no longer requires a subroutine call within SLUB.

[I am not sure that it is worth doing this because it changes the easy to
read structure of slub just to reduce atomic ops.  However, there is
someone out there with a benchmark on 4 way and 8 way processor systems
that seems to show a 5% regression vs.  Slab.  Seems that the regression is
due to increased atomic operations use vs.  SLAB in SLUB).  I wonder if
this is applicable or discernable at all in a real workload?]
