simplify dynamic bundle patching.

As it's impossible at present to compile and use IA32 support as a
module, disallow that; and also provide dummy functions to remove
compilation warnings if CONFIG_IA32_SUPPORT is off.

This makes the cpqfc driver recognize the HP Tachyon.  I moved the
device list to an __initdata structure so the driver doesn't build it at
runtime and changed it to use the proper PCI_DEVICE_ID_* names. 

With this patch applied, the driver happily detects the disks attached
to my HP Tachyon.

- Kill unneded parameters to ide_cmd_ioctl() and ide_task_ioctl().

- Apply Petr Vendrovecs fix for 32bit ver 16bit transfers.

- Make CD-ROM usable again by guarding the generic routines against request
   field abuse found there. We will try to convert this driver to the just to be
   finished struct ata_request after the generic changes stabilize a bit.
   The strcut ata_taskfile and struct ata_request merge to be more preciese.

- Don't provide symbolic links in /proc/ide - they are redundant data.

- Try to use a more reasonable default capacity value in ata_capacity().

- Fix ata_put() ata_get() usage in ide_check_media_change().

- Small readability fixes to the option parsing code.

- Apply Vojtech Pavliks /proc PIIX output fix.

- Replace all occurrences of ide_wait_taskfile() with ide_raw_taskfile().  One
   duplicated code path fewer.

Included is the latest version of the code. Indenting it properly
actually reduced the size of the files by another 10K or so.

Removes an atavism in declaration of sys_nfsservctl() - sorry, I should've
remove that junk when cond_syscall() thing was done.

dependency.  Non-legacy systems may have system memory
at 0xA0000, and if that's the case, we don't want to install the
VGA console.

Restructured conswitchp init slightly so that if both
CONFIG_DUMMY_CONSOLE and CONFIG_VGA_CONSOLE
are defined, conswitchp is always set to something, even if we
don't find VGA at 0xA0000.
