1) Correct memory barriers.  Routines not returning a value need
   no memory barriers, however routines returning values do need
   them.
2) Actually implement non-atomic ext2 bitops.

Thanks to Anton Blanchard for pointing out the memory barrier
requirements.

When a zone (usually DMA) has no active pages, pages_scanned (which
triggers all_unreclaimable) is only incremented when scanning the active
list. 

Make sure it's incremented for scanned cache entries too.

qeth network driver changes:
 - Improve performance by omitting svs.
 - Use function callback mechanism to set layer 2 parameters when getting
   a reply for a Layer 2 command.
 - dev->hard_header must not be NULL when fake_ll is no set since
   IPv6 and Layer2 needs the default function set by network stack.
 - ping6 works now when running in layer 2 mode.
 - Save original dev->hard_header to restore it when the user doesn't
   want to use fake_ll anymore.
 - Fake ethernet header in outgoing packets. This currently works
   only if qeth is compiled without ipv6 support.
 - Add more debug information in case of failures in qeth_set_offline.
 - Using fake_ll with HiperSockets devices results in misaligned
   ip packets and thus no traffic over HiperSockets.
 - Start qeth_remove_device only after the qeth recovery completed.

- Diagnose 8 needs a response buffer below 2GB real storage.
  As the caller cannot always allocate the buffer with GFP_DMA the best
  solution is to rewrite cpcmd to use a bounce buffer if necessary.
  The old function was renamed to __cpcmd and can be called if appropriate.
  The early boot code does not provide kmalloc but need cpcmd functionality.
  These places have been converted to use __cpcmd, as the init code and data
  are below 2GB.
- In case of an 31 bit system, cpcmd is defined as __cpcmd.
- EXPORT_SYMBOL(cpcmd) moved into cpcmd.c
- some whitespace fixes in cpcmd.[c/h]

Fix some bugs in device-mapper handling of 64-bit values, replacing
dm_div_up() and dm_round_up() inlines with macros and removing some
avoidable divisions of 64-bit numbers.

The mirror region size is the granularity used to manage and monitor the
data copying, typically 512KB, so 32 bits (of sectors) should be plenty to
hold this.

Taken together with the two earlier patches:
  "fix TB stripe data corruption" (a missing cast) and
  "stripe_width should be sector_t",
I've now had 3 independent reports that this fixes device-mapper
for devices with large stripes.

Still awaiting test results for dm-crypt and dm-raid1.
