svcauth_null_accept() and svcauth_unix_accept() are currently hard-wired to
check the source ip address on an incoming request against the export table,
which make sense for nfsd but not necessarily for other rpc-based services.

So instead we have the accept() method call a program-specific
pg_authenticate() method.  We also move the call to this method into
svc_process instead of calling it from the flavor-specific accept() routines.

This patch makes "find" work when traversing nohide exports on NFSv3.  The
READDIRPLUS reply needs to not return a file handle for the ".." entry when
the directory is a server side mountpoint, which would be the directory
itself, otherwise the client remembers the wrong file handle and gets
confused.

Use ARMv6 supersections for 16MiB static kernel direct mapped memory
regions when possible.
Based on comments received for the first version of this patch, this
version has added a comment to clarify that ARMv6 supersections are
only valid for the domain == 0 case and moved the supersection address
mask and size macros before the hardware page table definitions.

On some ARM-based processor's (eg, Atmel's AT91RM9200) it is necessary

Remove the include of bast-cpld.h, as it shouldn't be here as
it only defines some extra bast-specific registers, and does
not affect the configuration of the hardware dependenat items.
Ensure that the file is included in the one place it is needed
and not included.
This should discourage anyone else putting include files in

Patch from Ben Dooks

The patch does a number of updates, which are inter-dependant
on each other, for the s3c2440 support and some clean-ups for
all s3c24xx architecture in general.
1) Remove the s3c24xx_{fclk,hclk,pclk} variables, and pass
   these values to the clock core on initialisation. This
   removes the needless double copy, as only the timer code
   uses these directly (see point 4).
   Add an over-all xtal clock to the clock core
2) Add a sysdev driver to the clock code to ensure all the
   s3c2440 clocks are added if an s3c2440 is present.
3) Add the new IRQs to irq.c, and initialise them if the
   sysdev for the s3c2440 is present.
4) Change the timer code to request the timer clk and
   use it to get the frequency.
Depends on patch 2467/1

prompted this re-write.

Patch from Lennert Buytenhek

This patch makes the ixp2000 port use section mappings for on-chip
registers.  This has two advantages:
1. It saves some TLB entries.
2. It enables us to work around ixp2400 erratum #66, for which the
   suggested (and only) fix involves mapping all on-chip registers
   using XCB=101 instead of XCB=000.
This patch was derived from an older patch for the same erratum
(ARM patch ID 2265/1), made by Deepak Saxena.
Note that this patch does not actually constitute a workaround for
erratum #66, it merely lays the foundation for such a workaround.
