blk_run_page() is incorrectly using page->mapping, which makes it racy against
removal from swapcache.

Make block_sync_page() use page_mapping(), and remove bkl_run_page(), which
only had one caller.

Split the system_state state `SYSTEM_SHUTDOWN' into SYSTEM_HALT,
SYSTEM_POWER_OFF and SYSTEM_RESTART and export system_state to modules.

This allows driver shutdown routines to know why they are being shutdown.  The
IDE subsystem wants this so that it knows to not spin the disks down across a
reboot.

This allows building the math-emu code as a module only when
CONFIG_SMP is not set. The fp trap handler cannot be preempted
on a single-CPU (as CONFIG_PREEMPT is not going to be supported
on alpha), so the module can be safely unloaded at any time.

Avoid warnings about truncating them when building the
name database.

Seperate function, cruft removed and old_hwif

With minor fixes from me

reiserfs_file_write unlocks the pages it operated on before updating
i_size.  This can lead to races with writepage, who checks i_size when
deciding how much of the file to zero out.

This patch also replaces SetPageReferenced with mark_page_accessed() in
reiserfs_file_write

This was verified to fix the BitKeeper data corruption problems that
Steven Cole has been debugging, where concurrent writes to a file and
writebacks to disk would cause zeroes in the file when CONFIG_PREEMPT
was enabled.

- clear hwif->hw in setup-pci.c before using it

- fix arch/arm/Kconfig to allow IDE only on platforms supporting it

- introduce IDE_ARCH_OBSOLETE_INIT and ide_default_io_ctl() so
  we can use generic ide_init_hwif_ports() and kill no longer needed
  <asm-arm/arch-*/ide.h> (leave broken lh7a40x and sa1100 versions)

Cross-compile tested on ARM.

Add drivers/ide/arm/ide_arm.c for simple default IDE interfaces
and clean obsolete ide_init_default_hwifs() implementations
in asm-arm/arch-{cl7500,rpc,shark}/ide.h and asm-arm26/ide.h.

This allows us to kill ide_init_default_hwifs() completely
in the next patch (because lh7a40x and sa1100 are broken).

Cross-compile tested on ARM.

* Convert all netdev->priv references to the fancy new netdev_priv().

* Reads/writes from/to eeprom using ethtool weren't working right
  on big-endian.  Now they are.

* Changed mapping on Rx skb to bi-directional.  skb->data holds both the
  RFD structure and the packet data, and the RFD is read/written by
  HW.  Issue found on Xscale HW that doesn't handle cache syncs auto-
  matically.  Other changes in patch are whitespace/spelling.
