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.

Rename print_backtrace to show_stack and improve it, remove the
#if 0 around set_fpexc mode and add get_fpexc_mode, add the
__NR_security define and reserve syscall 225 for Tux.

We don't unmask the interrupt at the end of handling it if there
is no action (i.e. someone has done free_irq).  Add some likely
and unlikely hints and fix synchronize_irq.

in preference to probing at startup.

We now use boot_mem_size if it is nonzero and only call
ppc_md.find_end_of_memory if boot_mem_size is zero.

This is invoked by mount -remount,resize=<blocks>.

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.
