 - trivial: cache file->f_dentry->d_inode; saves a few bytes of compiled
   size.
 - move expand_stack inside ARCH_STACK_GROWSUP, add an alternate
   implementation for PA-RISC.
 - partially fix the comment (mmap_sem is held for READ, not for WRITE).
   It still doesn't make sense, saying we don't need to take the spinlock
   right before we take it.  I expect one of the vm hackers will know
   what the right thing is.

Testing of course revealed some bugs introduced during the cleanups,
so these are fixed here with a couple of other small bits, like improved
debugging code.

This is invoked by mount -remount,resize=<blocks>.
See Documentation/filesystems/jfs.txt for more information.

This brain fart is left over from some cleanup of these functions a _long_ 
time ago. We need to dput() the dentry, since we have an implicit count of
one left over from the create function.

Instead, we were dput() on the directory that it was in, which we didn't 
have a matching dget() for.

In order for JFS to be able to quiesce the current activity, while
blocking new transactions, the locking needed some rework.  New
transactions are stopped in the functions txBegin or txBeginAnon,
where the rdwrlock (IREAD_LOCK/IWRITE_LOCK) may be held.  Dirty
inodes may need to be committed while new transactions are blocked
here, so another lock is introduced (commit_sem) which is taken after
txBegin/txBeginAnon is called.  This ensures that the proper
serialization takes place, without the write_inode method needing to
grab the rdwrlock.

In addition, the use of IWRITE_LOCK and IREAD_LOCK has been removed
from directory inodes.  The serialization done by the VFS using i_sem
is sufficient to avoid races.

This patch removes JFS's dependency on down_write_trylock.
