The kernel currently prints:

 nfsd: nobody listening for auth.unix.ip upcall; has some daemon not been started?

on every bootup, during initscripts.

Neil Brown <neilb@cse.unsw.edu.au> says:

  It was part of the recent set of idmapper patches.  Bruce wanted the admin
  to get a warning when the idmapper daemon wasn't running.  I thought the
  same warning should apply to any daemon that responded to upcalls.

  In the case of auth.unix.ip it isn't strictly necessary for a daemon to be
  running (for comparability with 2.4).

  You can get rid of the warning by doing:

    mount -t nfsd nfsd /proc/fs/nfs

  before mountd is started (init scripts should start doing this I hope, but
  distributions don't tend to use the init script from nfs-utils, so it is
  hard to push it).  This will trigger mountd to listen on auth.unix.ip and
  others.


That's a hassle, so Bruce's patch limits the warning purely to the new
idmapper cache.  It provides a callback in the cache_detail that individual
caches can use to log messages when upcalls fail because a userspace daemon
not running.  Implement this method for the idmapping caches.

There are a few include which should have been under __KERNEL__.

Early in the boot process on pSeries machines, we look in the Open Firmware
device tree for information about the interrupt assignments, and assign
virtual IRQ numbers for each physical IRQ.  There is currently a couple of
bugs in this code which result in us assigning virtual IRQs for nonexistent
physical IRQs.  This causes problems when we call the firmware to enable or
disable those nonexistent physical IRQs.  Some versions at least of the
firmware will hit an assertion failure and crash the machine when this
happens.

This patch fixes the bugs and ensures that we don't try and use nonexistent
physical IRQ numbers.  One bug was that we were mapping ISA interrupts,
which is unnecessary since virtual IRQ numbers 0 - 15 are reserved for
them.  The other was that when we had a PCI interrupt (which is always in
the range 1 to 4, corresponding to INTA to INTD) which didn't have a
mapping in the PCI host bridge above it, we were just using the original
number (usually 1) rather than ignoring it.

We have cards that want over 2MB of PCI consistent memory.  The
IOMAP_MAX_ORDER limit is just to catch bad drivers early, so we can bump
this a bit.

We want some room to grow but our maximum get_free_pages allocation on
ppc64 is currently 16MB, so it doesnt make sense to go above that.

enter_rtas now takes an unsigned long.

This patch allows us to dynamically add virtual disks to an iSeries partition.
 It works like this: after you have created the virtual disk file on OS/400
and attached it to the Linux partition, you need to write to
/sys/bus/vio/drivers/viodasd/probe (it doesn't matter what you write).  This
will do the probe.  It calls add_disk() for each new disk, so we get hotplug
events as a side effect.

This was the nicest way I could think of doing this as the interface to the
hypervisor is polled ...

Fix a couple of nasty lurking bugs in viopath.c and add information
required to know if the iseries_veth module should be loaded on legacy
iSeries systems.

From: Anton Blanchard, Dave Hansen and Olof Johansson:

Fix multiple bugs in the ppc64 NUMA topology probe code.

- We were using HW cpu numbers instead of logical ones.  615, 630, 650,
  some 670 and some 690 SMP will all fail to boot without this patch.

- The old code would BUG() when it got confused (more NUMA zones than the
  kernel is configured for etc).

- The common depth calculation was incorrect.  Dave found an OF property
  that gives us exactly what we want.

- Things were broken on SMT machines.

The new code should work on those broken systems and should no longer BUG()
but fall back to a flat topology when it gets confused.

In _raw_spin_lock_flags we were branching to the wrong spot and would
restore random stuff to the MSR.

From: Zdenek Pavlas <pavlas@nextra.cz>

On any x86 without cpuid, early_cpu_detect() left x86_cache_alignment as
zero, so kmem_cache_init() calls cache_estimate() with align == 0, and
it loops forever. I've tried this trivial fix, and it works for me.

Andi Kleen looked over this, and ok'd it.

This improves the stack traces we get on PPC64 by putting a marker in
those stack frames that are created as a result of an interrupt or
exception.  The marker is "regshere" (0x7265677368657265).

With this, stack traces show where exceptions have occurred, which can
be very useful.  This also improves the accuracy of the trace because
the relevant return address can be in the link register at the time of
the exception rather than on the stack.  We now print the PC and
exception type for each exception frame, and then the link register if
appropriate as the next item in the trace.

- access SA1111 GPIO using sa1111_set_io functions.
- access Lubbock misc register using lubbock_set_misc_wr
- fix CF voltage selection.
- don't fiddle with PCMCIA voltage selection when selecting CF
  voltage.
- wait for the voltage switches to stabilise before reading the
  new card state.

Patch from Ian Campbell

The recent changeset "Sanitise handling of unneeded syscall stubs" missed

__ARCH_WANT_SYS_PAUSE from include/asm-arm/unistd.h.

Disabling IRQs over context switches causes unreasonable IRQ latency
on VIVT cached machines, so provide our own prepare_arch_switch(),
finish_arch_switch() and task_running() implementations.  We provide
an optimised UP version so we don't end up needlessly incrementing
and decrementing the preempt count.

These are supposed to be ordered by option name.

Using these old definitions on PXA will result in randomly
scribbling over memory.  Remove them.

Any architecture (like pa-risc) that makes use of the helper function
flush_dcache_mmap_lock() won't compile with the new rmap due to use of
the wrong "mapping". 

Trivial fix.

- There are only 16 entries in the pseudo palette
- For dual-panel displays, we need to halve the display height
- When disabling the LCD controller, use LCCR0_DIS (aka slow disable)
  rather than quick disable.
- Clean up compiler warnings.

Some SA1111 devices are unable to clear the PS/2 receive IRQ before
it has been serviced, so we always re-enter the handler one more
time than is strictly necessary.  We can't clear the IRQ after
servicing because that causes race conditions with other SA1111
devices, so we take the easy option and always return IRQ_HANDLED.

- Move CKEN manipulation into power management handling (so we don't
  shut down the clock to the console port.)
- .iotype should be using UPIO_xxx not SERIAL_IO_xxx
- Remove each port when module is unloaded.
- Remove needless #include.
- Remove ASYNC_SKIP_TEST - we don't have any tests to skip.

This provides an atomic method to update the Lubbock board specific
register from various drivers.

Fix an oops caused by a missing failure return value for devices which
do not require DMA bouncing.

The PCMCIA devices are not devices for the kernel and the bt3c_cs
driver uses a fake device for calling request_firmware(). The fake
device initialization must also set .kobj.k_name to prevent an oops
until PCMCIA devices are fully integrated into the driver model.

It is not possible to use __module_get() when adding a new RFCOMM
session, because there is a case where no reference count is hold.
This happens when the module is not in use right now and an incoming
connection occurs.
