Al updated Documentation/filesystems/porting with 2.5 changes but there
is no mention of lseek.  The following patch, against 2.5.5, adds lseek
to the list of functions that no longer are called with the BKL.

	Robert Love

The attached patch implements proper locking in ALSA lseek methods.
Note ALSA has 3 lseek implementations, but only:

	sound/core/info.c :: snd_info_entry_llseek()

requires locking.  I wrapped the function in the BKL.  According to
Jaroslav Kysela the gus_mem_proc method is only called from above.  The
third lseek, in hwdep.c, clearly doesn't need locking.  Without this
patch, the above lseek is not safe.

This patch add the validity check of 2 values (fats, reserved). These
values must not be 0.

Here enclosed patch for eata.c, eata.h, u14-34f.c, u14-34f.h
to be applied to lk-2.5.5.

eata.c:
       + Remove any reference to virt_to_bus().
       + Fix pio hang while detecting multiple HBAs.
       + Fixed a board detection bug: in a system with
         multiple ISA/EISA boards, all but the first one
          were erroneously detected as PCI.

u14-34f.c:
       + Remove any reference to virt_to_bus().
       + Fix pio hang while detecting multiple HBAs.

After BKL was moved from the VFS into the filesystem's methods in the lookup
call, we do not need to check BKL is actually held (we know it is not).
This patch patch removes unneeded lock_depth check.
Without this patch reiserfs cannot be used on SMP.

2.5.5 Oopses at boot time with a disk in a zipdrive.
With this patch all is fine. I have not read the
patch, certainly not checked it for correctness,
just observed that it works for me.
I think the author is Rich Baum.

Fix i810 audio for DMA mapping (from Pete Zaitcev).

Numerous LVM fixes & cleanups.
Gets things compiling again, and allegedly works according to feedback.
Mostly from Anders in absence of any maintainence by LVM people.

There are two critical problems with lvm in 2.5.2-pre11 (and earlier).
* ioctls on the chardev allocates a >4k lv_t on stack. if the ioctl is
LV_CREATE, LV_EXTEND, LV_REDUCE or LV_RENAME data is copied into this
and the task_struct will most certainly be corrupted.
* sizeof(lv_t) differs between user and kernelspace. The userspace version
of the lv_t structure is much smaller than the kernelspace version. This
leads to corruption of memory in the userspace application when an lv_t is
copied from kernelspace to userspace, as in "vgdisplay -v"

The following patch addresses these two issues. It puts the user-space
version of the lv_t into a substructure of the kernelspace version. When
communicating to userspace just the userlv_t part is used. This avoids the
allocation of the lv_t on the stack by allocation just a userlv_t instead.

1.  Kill the ide-probe-mod by merging it with ide-mod. There is *really*
    no reaons for having this stuff split up into two different
    modules unless you wan't to create artificial module dependancies
    and waste space of page boundaries during memmory allocation for the
    modules

2.  Kill the ide_module_t - which is unnecessary and presents a
    "reimplementation" of module handling inside the ide driver.  This
    is achieved by attaching the initialization routine ot the
    ide_driver_t, which will be gone next time, since there is no sane
    reason apparently, which this couldn't be done during the
    module-generic initialization of the corresponding driver module.

3.  Kill unnecessary tagging of "subdriver" with IDE_SUBDRIVER_VERSION -
    we have plenty of other mechanisms for module consistency checking.
    And anyway the ide code didn't any consistence checks on this value
    at all.

NOTE: The ide_(un)register_module() functions will be killed in next round.

The attached patch does:

1. Kill two exports which mankind will never know what they where good for

2. Kill duplicated comments.

3. Kill declarations of never defined functions

4. Some other minor tidups here and there.
