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.

Remove a lot of un-used and un-needed libgcc funstions from export list
for m68knommu syms.

Correct build lines for Motorola Dragonball 68x328 frame buffer driver. 

Patch from Georges Menie <georges@menie.org>

Remove ColdFire specific code sections for atomic_add and atomc_sub.

These are not needed, the m68k asm code for these functions is ColdFire
clean.

We should un-define all the x86 style IO routines when redefining local
versions.

Create init points for the Motorola Dragonball 68x328 frame
buffer driver.

Patch from Georges Menie <georges@menie.org>

A couple of fixups for asm-m68knommu/bitops.h:

. re-order definition of fls(), to be outside __KERNEL__
. add code for find_next_bit()

Big cleanup of the Motorola DragonBall 68x328 frame buffer.  It was
quite broken before. 

Patch from Georges Menie <georges@menie.org>.

Fix the cache flushing code for the ColdFire 5407 CPU.

The cpushl instruction arguments are wrong, causing it to miss some
cache lines.

Added a nommu version of sysctl_max_map_count.

Fix return value from do_munmap(), it should return 0 on success not
EINVAL.

Fix bug #2661

Raid currently calls ->unplug_fn under spin_lock_irqsave(), but unplug_fns
can sleep.


After a morning of scratching my head and trying to come up with some that
does less locking, the following is the best I can come up with.  I'm not
proud of it but it should work.

If I move "nr_pending" out or rdev into the per-personality structures
(e.g.  mirror_info), and if I had "atomic_inc_if_nonzero" I could do with
without locking so much, but random atomic* functions don't seem trivial

        spinlock_t *lp = &((struct netdev_private *)dev->priv)->lock;

There was a spin_unlock missing in the raw mode tx-completion path.  Probably
it slipped through because the raw mode stuff is never reached with my Actisys
hardware.

There is a uninitialized goal value being referenced in both ext3 and ext2
find goal block functions (ext3_find_goal() and ext2_find_goal()).

In the non-sequential write case, these functions check the goal value(non
zero) before calling ext3(2)_find_near() to find the goal block to
allocate.

Since the goal value is uninitialized(non zero), the ext3(2)_find_near() is
never being called in the non-sequential write, thus ext3(2)_find_goal()
failed to guide a goal block in the random write case.

ext3(2)_new_block() takes the junk goal value and will turn it to goal 0
since it's normally beyond the filesystem block number limit.  The fix is
trivial.

The IA64 hotplug CPU merge seems to have included some core changes: in
particular the recalc_bh_state() needs to sum for all (including offline)
cpus, since we don't empty the counters on CPU down.  The totals printed by
/proc/stat (the first loop) should include offline cpus, too (apparently
printing out the per-cpu lines for offline cpus confuses top).

The recent ARM-specific fix broke ia32.  Hopefully the ARM team can find an
arch-specific implementation of VGA_MAP_MEM() which makes it work.

Doing the algebra:

c = (a - b) * 3/2
a' = a - c = a - 3/2(a - b) = (2a - 3a + 3b)/2 = (3b - a)/2
a' >= 0
3b - a >= 0
3b >= a
b >= a/3
nr_free_pages() >= mempages/3

We can indeed get into trouble if we try to load a large kernel on a very
small box (ie kernel reserves more than 2/3 of usable memory).  Surprisingly I
haven't hit this, but here's a fix.

svc_recv may call svc_sock_release before rqstp->rq_res is initialized.
