This adds basic support to md.c.

This makes swsusp 64bit compatible, and makes it work in case of two
mirrors of physical memory (x86-64 works like that). It also contains
few accumulated cleanups.

swsusp: Move loop variables into assembly, where they are used.

This moves CONFIG_SOFTWARE_SUSPEND where it belongs, and makes
ACPI_SLEEP depend on it to prevent compile problems.

  If the call to devfs_register() fails, then the driver does not deregister
  its misc device before returning an error. This should fix it.

  	1) removes one call to check_region
  	2) uses request_region instead
  	3) calls release_region in case of driver initialisation error later on

  Every definition if sigmask() was the same.  In one case it was
  mutilply defined for the arm architecture.  This patch removes all the
  architecture defines of sigmask and moves the generic define from
  the protection of __HAVE_ARCH_SIG_BITOPS.

  As far as I can see, setup_arg_pages code is hosed for the

  Does any arch even use this?

  	timer_exit() isn't a public function, and doesn't even exist in 2.5.
