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.

	this is a sync with the current ALSA CVS tree (last code
modification: (Sun Feb 17 17:46:41 2002 UTC)) and 2.5.5-pre1 code and
contains:

- ALSA code version 0.9.0beta11
- Config.in files updated (separated associated drivers to submenus)
- global sound/Makefile fixes
- added inclusion of missing header files for alpha architecture
- fixed power functions (bad locking)
- fixed copy_to_user calls (removed them from spinlocks)
- fixed freeing of resource structures
- fixed AD1816A driver (inverted volume controls)
- added new functions to allocate ISA DMA memory (cleanups in ISA drivers)
- updated ISA PnP detection in wavefront driver
- added joystick support for VIA686
- updated ES1968 (Maestro2) driver
- moved joystick support for YMFPCI to the control interface
- updated Korg1212 driver

Fixes overflow checks in smb_encode_path().

Adds an obvious helper, converts callers.

helper for safe access to parent's inumber

hfs compile fixes

  this patch adds support for older MGA-TVO-B (found on G200-TV)
to matroxfb.

			Petr Vandrovec

(1) Updates documentation.
(2) Remove 'current' and 'previous' hardware fields. X just do not play fair,
    and one cannot assume anything about current hardware state.
(3) Changes algorithm for computing PLL parameters to one used by Matrox. On
    recent chips (G550) there are no limits for PLL, you just have to try
    couple of possible combinations to find which one works on this
    particualr hardware.
(4) Add code which can intialize G450/G550 when BIOS did not initalize it
    (non-ia32 hardware, secondary devices on ia32 hardware).

				Petr Vandrovec

* move socket clearing code from sock_alloc to sock_alloc_inode, so
  root of socketfs does not contain garbage, and we have all initialization
  in one place
* add initialization of passcred to zero - otherwise it is left on some
  random value, causing at least autobind() to randomly fail on
  unix sockets

			Petr Vandrovec

* ipx needs cleared ipx_sk, mainly intrfc pointer member.
  Fixes boottime oops.

The patch has been changed like you wanted, with page->zone
shoved into page->flags. I've also pulled the thing up to
your latest changes from linux.bkbits.net so you should be
able to just pull it into your tree from:

Rik

- pte_offset_map2 => pte_offset_map_nested
- pte_unmap2 => pte_unmap_nested

adds simple support for atomically-mapped PTEs. On highmem systems this enables the allocation of the pagetables in highmem.

- the new vmalloc_to_page() interface should be used to determine the physical page a given vmalloc() area virtual address is mapped to.

This patch (+ BK changeset) converts the meye driver to the new DMA API,
this is necessary for the driver to be used in 2.5. 

Stelian.

ChangeSet@1.332, 2002-02-15 16:35:31+01:00, stelian@popies.net
  Convert to the new DMA API and allocate separate DMA pages instead of one big buffer.
