The ppc64 head.S contains an enable_32b_mode function which is used
nowhere.  This patch removes it.

From: Paul Mackerras <paulus@samba.org>

This patch fixes a whole pile of problems in the xmon kernel debugger for
ppc64.  This basically makes xmon SMP-safe.  Now, when we enter xmon it
sends an IPI to the other CPUs to get them into xmon too.  It also changes
the way we do single-stepping and breakpoints so that we don't have to
remove a breakpoint to proceed from it (instead we either emulate the
instruction where the breakpoint was, or execute it out of place).  With
this patch, if we get an exception inside xmon, it will just return to the
xmon command loop instead of hanging the system as at present.

The patch is quite large because it updates the disassembler to the latest
version from binutils (trimmed a bit), which is why I didn't cc lkml.

When I added the out-of-line spinlocks on PPC64, I inadvertently introduced
a bug in the inline version of _raw_spin_trylock, where it returns the
opposite of what it should return.  The patch below fixes it.

This fixes busted asm constraints for readq & writeq implementation on
ppc64 that resulted in garbage beeing generated for writeq (plus an obvious
mistake in the prototype).

When hotplug cpu isn't enabled, cpu_is_offline is always false.  I had a stuck
cpu at boot that resulted in a lockup because we tried to start a migration
thread on it.  Instead of cpu_is_offline we can use !cpu_online which should
cover both the hotplug cpu enabled and disabled cases.

    when mounting an NFS filesystem.

RPC: Make "major" timeouts be of fixed length "timeo<<retrans"
     rather than counting the number of retransmissions. The
     clock starts at the first attempt to send each request.
                                                                                
RPC: Ensure that we "slow start" the RTT estimation after a
     major timeout has occurred.

    no longer calls the generic VFS read and write routines.
    This allows all application read requests to pass through
    to the server, instead of just the ones that appear to be
    inside the file. this eliminates the requirement to use a
    GETATTR operation before each read or write to determine
    where the EOF is. This is a significant performance and
    scalability win.

    It also removes all requirements for holding the inode
    semaphore during NFS direct reads and writes, as the read
    and write logic no longer needs atomic access to the size
    of the file. this also helps client CPU scalability by
    reducing the serialization of writes against a single file.

In several functions, d_instantiate is called before the transaction
is committed.  Under the rare condition that txCommit fails, the new
inode is released, but the dentry continues to point to it.  This
can lead to a seg fault.  The fix is to call d_instantiate after
txCommit has run successfully.

The jfs_log structure was never being freed at unmount time.

The NFS readlink() methods all take a buffer length argument.  Use that
instead of assuming PAGE_SIZE... 

We need to return ENAMETOOLONG rather than EIO.

Make sure NFS client doesn't see errors from mode setting on new symlinks.

When nfsd creates a symlink, it tries to set the mode as the mode is 
carried in the NFS request and some filesystems store a mode.

If the filesystem refuses to set the mode (e.g. -EOPNOTSUPP), this
error should not be returned to the client.

This adds support for the CP-104 Moxa Smartio serial cards.  Just add
the PCI ID information.

When the kmem_bufctl_t typedef got added to include/asm-ppc64/types.h,
it got added outside the #ifndef __ASSEMBLY__ section, causing
assembler errors.  This patch, from David Gibson, moves it inside the
#ifndef __ASSEMBLY__ region.

Add newlines to some printk debug trace of comempci.c driver.
