The first 2.5.2 prepatch

Kernel.org: The first Linux 2.5.2 prepatch is now out. You can get it here, or you can use one of the mirrors. Please remember to read the changelog.

pre1:
 - me: revert the "kill(-1..)" change.  POSIX isn't that clear on the
   issue anyway, and the new behaviour breaks things.
 - Jens Axboe: more bio updates
 - Al Viro: rd_load cleanups. hpfs mount fix, mount cleanups
 - Ingo Molnar: more raid updates
 - Jakub Jelinek: fix Linux/x86 confusion about arg passing of "save_v86_state" and "do_signal"
 - Trond Myklebust: fix NFS client race conditions
