The mips_rtc_lock is no longer needed because RTC operations should be
protected already by other mechanism. (rtc_lock, local_irq_save, etc.)
    
Also, locking whole rtc_get_time/rtc_set_time should be avoided while
some RTC routines might take very long time (a few seconds).

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.

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.

converted to struct fb_monspecs and a private modelist.  The search will be
done in this manner:

- if 1st detailed timing is preferred, use that
- else if dimensions of the display are known, use that to estimate xres and
- else if modelist has detailed timings, use the first detailed timing

including it.  I've generated a font_rl.c file and related minor

is why I use it and selected it for conversion.  I believe the font is GPL'd.

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.

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.

There are a couple of tests which could possibly be confused by extremely
large numbers appearing in 'xdr' packets.  I think the closest to an exploit
you could get would be writing random data from a free page into a file - i.e.
 leak data out of kernel space.

I'm fairly sure they cannot be used for remote compromise.
