Al Viro 7b7b1ace2d [PATCH] saner handling of auto_acct_off() and DQUOT_OFF() in umount
The way we currently deal with quota and process accounting that might
keep vfsmount busy at umount time is inherently broken; we try to turn
them off just in case (not quite correctly, at that) and

  a) pray umount doesn't fail (otherwise they'll stay turned off)
  b) pray nobody doesn anything funny just as we turn quota off

Moreover, LSM provides hooks for doing the same sort of broken logics.

The proper way to deal with that is to introduce the second kind of
reference to vfsmount.  Semantics:

 - when the last normal reference is dropped, all special ones are
   converted to normal ones and if there had been any, cleanup is done.
 - normal reference can be cloned into a special one
 - special reference can be converted to normal one; that's a no-op if
   we'd already passed the point of no return (i.e.  mntput() had
   converted special references to normal and started cleanup).

The way it works: e.g. starting process accounting converts the vfsmount
reference pinned by the opened file into special one and turns it back
to normal when it gets shut down; acct_auto_close() is done when no
normal references are left.  That way it does *not* obstruct umount(2)
and it silently gets turned off when the last normal reference to
vfsmount is gone.  Which is exactly what we want...

The same should be done by LSM module that holds some internal
references to vfsmount and wants to shut them down on umount - it should
make them special and security_sb_umount_close() will be called exactly
when the last normal reference to vfsmount is gone.

quota handling is even simpler - we don't use normal file IO anymore, so
there's no need to hold vfsmounts at all.  DQUOT_OFF() is done from
deactivate_super(), where it really belongs.

Adrian Bunk b449f63c8c [PATCH] drivers/pnp/: cleanups
This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global function:
  - core.c: pnp_remove_device
- #if 0 the following unneeded EXPORT_SYMBOL's:
  - card.c: pnp_add_card
  - card.c: pnp_remove_card
  - card.c: pnp_add_card_device
  - card.c: pnp_remove_card_device
  - card.c: pnp_add_card_id
  - core.c: pnp_register_protocol
  - core.c: pnp_unregister_protocol
  - core.c: pnp_add_device
  - core.c: pnp_remove_device
  - pnpacpi/core.c: pnpacpi_protocol
  - driver.c: pnp_add_id
  - isapnp/core.c: isapnp_read_byte
  - manager.c: pnp_auto_config_dev
  - resource.c: pnp_register_dependent_option
  - resource.c: pnp_register_independent_option
  - resource.c: pnp_register_irq_resource
  - resource.c: pnp_register_dma_resource
  - resource.c: pnp_register_port_resource
  - resource.c: pnp_register_mem_resource

Note that this patch #if 0's exactly one functions and removes no
functions.  Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular
code will use any of them, re-adding will be trivial.

Modular ISAPnP might be interesting in some cases, but this is more legacy
code.  If someone would work on it to sort all the issues out (starting
with the point that most users of __ISAPNP__ will have to be fixed)
re-enabling the required EXPORT_SYMBOL's won't be hard for him.

Ville Syrjälä 63921fbfbd [PATCH] matroxfb: Add support for Mystique AGP
Add new entries for Mystique AGP with the PCI ID 0x051e.

I don't actually have such boards but according to google they do exist.
Curiosly X.Org doesn't recognize that PCI ID.  And what's even more
interesting is that Matrox's own Windows drivers don't recognize it either.
After going through about a dozen different versions I did find one older
driver that does list this particular ID.  It is also listed in the pci.ids
file.

I'm not sure if non-220 AGP chips exist.  I left the chip revision check
intact for AGP chips nonetheless.

- if 1st detailed timing is preferred, use that

- else if modelist has detailed timings, use the first detailed timing
- else, use the very first entry from the modelist

Michal Januszewski 8fb6567e34 [PATCH] fbdev: fix the fb_find_nearest_mode() function
Currently the fb_find_nearest_mode() function finds a mode with screen
resolution closest to that described by the 'var' argument and with some
arbitrary refresh rate (eg.  in the following sequence of refresh rates: 70 60
53 85 75, 53 is selected).

This patch fixes the function so that it looks for the closest mode as far as
both resolution and refresh rate are concerned.  The function's first argument
is changed to fb_videomode so that the refresh rate can be specified by the
caller, as fb_var_screeninfo doesn't have any fields that could directly hold
this data.

Antonino A. Daplas c465e05a03 [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbcon
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
drivers that do not support hardware cursors is redundant.  The soft_cursor
function is usable by all drivers because it is just a wrapper around
fb_imageblit.  And because soft_cursor is an fbcon-specific hook, the file is
moved to the console directory.

Thus, drivers that do not support hardware cursors can leave the fb_cursor
field blank.  For drivers that do, they can fill up this field with their own
version.

The end result is a smaller code size.  And if the framebuffer console is not
loaded, module/kernel size is also reduced because the soft_cursor module will
also not be loaded.

Corey Minyard 393d2cc354 [PATCH] ipmi: use refcount in message handler
This patch is rather large, but it really can't be done in smaller chunks
easily and I believe it is an important change.  This has been out and tested
for a while in the latest IPMI driver release.  There are no functional
changes, just changes as necessary to convert the locking over (and a few
minor style updates).

The IPMI driver uses read/write locks to ensure that things exist while they
are in use.  This is bad from a number of points of view.  This patch removes
the rwlocks and uses refcounts and RCU lists to manage what the locks did.
