There is some confusion about the meaning of 'bufsz' for a sunrpc server.
In some cases it is the largest message that can be sent or received. In
other cases it is the largest 'payload' that can be included in a NFS
message.
In either case, it is not possible for both the request and the reply to be
this large. One of the request or reply may only be one page long, which
fits nicely with NFS.
So we remove 'bufsz' and replace it with two numbers: 'max_payload' and
'max_mesg'. Max_payload is the size that the server requests. It is used
by the server to check the max size allowed on a particular connection:
depending on the protocol a lower limit might be used.
max_mesg is the largest single message that can be sent or received. It is
calculated as the max_payload, rounded up to a multiple of PAGE_SIZE, and
with PAGE_SIZE added to overhead. Only one of the request and reply may be
this size. The other must be at most one page.

Add a way for a no_page() handler to request a retry of the faulting
instruction. It goes back to userland on page faults and just tries again
in get_user_pages(). I added a cond_resched() in the loop in that later
case.
The problem I have with signal and spufs is an actual bug affecting apps and I
don't see other ways of fixing it.
In addition, we are having issues with infiniband and 64k pages (related to
the way the hypervisor deals with some HV cards) that will require us to muck
around with the MMU from within the IB driver's no_page() (it's a pSeries
specific driver) and return to the caller the same way using NOPAGE_REFAULT.
And to add to this, the graphics folks have been following a new approach of
memory management that involves transparently swapping objects between video
ram and main meory. To do that, they need installing PTEs from a no_page()
handler as well and that also requires returning with NOPAGE_REFAULT.
(For the later, they are currently using io_remap_pfn_range to install one PTE
from no_page() which is a bit racy, we need to add a check for the PTE having
already been installed afer taking the lock, but that's ok, they are only at
the proof-of-concept stage. I'll send a patch adding a "clean" function to do
that, we can use that from spufs too and get rid of the sparsemem hacks we do
to create struct page for SPEs. Basically, that provides a generic solution
for being able to have no_page() map hardware devices, which is something that
I think sound driver folks have been asking for some time too).
All of these things depend on having the NOPAGE_REFAULT exit path from
no_page() handlers.

Tim and Ananiev report that the recent WARN_ON_ONCE changes cause increased
cache misses with the tbench workload. Apparently due to the access to the
newly-added static variable.
Rearrange the code so that we don't touch that variable unless the warning is
going to trigger.
Also rework the logic so that the static variable starts out at zero, so we
can move it into bss.
It would seem logical to mark the static variable as __read_mostly too. But
it would be wrong, because that would put it back into the vmlinux image, and
the kernel will never read from this variable in normal operation anyway.
Unless the compiler or hardware go and do some prefetching on us?
For some reason this patch shrinks softirq.o text by 40 bytes.

Avoid the use of an uninitialized stack variable when the powerpc device tree
bootargs property is either missing or incorrectly defined. This also makes
CONFIG_CMDLINE work properly under these conditions. This change adds a test
for the existence of the bootargs property.
early_init_dt_scan_chosen() tests for a zero length bootargs property in its
CONFIG_CMDLINE processing, but the current implementation of
of_get_flat_dt_prop() doesn't assign a value to the length when no property is
found. Since an automatic variable is used, a stale value from the stack will
be used in the test.

This patch adds checking of the PCI_INTERRUPT_PIN register before
using standard OF parsing to retreive PCI interrupts. The reason is
that some PCI devices may have no PCI interrupt, though they may have
interrupts attached via other means. In this case, we shall not use
irq->pdev, but device-specific code can later retreive those interrupts
instead.
Without that patch, Maple and derivatives don't get the right interrupt
for the second IDE channel as the linux IDE code fallsback to the PCI
irq instead of trying to use the legacy ones for the on-board controller
(which has no PCI_INTERRUPT_PIN). Having no PCI IRQ assign to it (as it
doesn't request any) fixes it.

The "linux,tce-size" property is only 32 bits (see
prom_initialize_tce_table() in arch/powerpc/kernel/prom_init.c).
Treating it as an unsigned long in iommu_table_setparms() leads to
access beyond the end of the property's buffer, so we pass garbage to
the memset() in that function.
