Even on uniprocessor we always reported the number of physical
cpus in the system via /proc/cpuinfo.  But when this got changed
to use num_possible_cpus() it always reads as "1" on uniprocessor.
This change was unintentional.

So scan the firmware device tree and count the number of cpu
nodes, and report that, as we always did.

Currently recvmsg generates SIGPIPE whereas sendmsg does not; for the
other stacks it seems to be the other way round!

It also fixes the bug where reading from a socket whose peer has shutdown
returned -EINVAL rather than 0.

This will let me chop the code size of several drivers right down. In
many cases the actual private data is very useful and constant for a
given host controller so being able to just pass it at probe time would
be very useful indeed (eg with the via driver would could pass the udma
clocking and reduce the code size, or with the AMD one the UDMA
multiplier and the offset)

We needed the VDSO symbols in the arch/ppc asm-offsets.c, and there
were a few usages of _systemcfg still left lying around.

When we created the instructions to read/write SPRs in xmon, we were
setting up a ppc64-style procedure descriptor and calling that, which
doesn't work in 32-bit.  For 32-bit a function pointer just points
to the instructions of the function.  This fixes it to do the right
thing for both 32-bit and 64-bit.

32-bit SMP powermacs weren't booting with ARCH=powerpc because the
boot cpu wasn't saving away the state of various control registers,
but the secondary CPUs were loading them from the uninitialized
state.  This adds the necessary save-state call.
Signed-off-by: Paul Mackerras <paulus@samba.org>

This patch moves the vdso's to arch/powerpc, adds support for the 32
bits vdso to the 32 bits kernel, rename systemcfg (finally !), and adds
some new (still untested) routines to both vdso's: clock_gettime() with
support for CLOCK_REALTIME and CLOCK_MONOTONIC, clock_getres() (same
clocks) and get_tbfreq() for glibc to retreive the timebase frequency.

Tom,Steve: The implementation of get_tbfreq() I've done for 32 bits
returns a long long (r3, r4) not a long. This is such that if we ever
add support for >4Ghz timebases on ppc32, the userland interface won't
have to change.

I have tested gettimeofday() using some glibc patches in both ppc32 and
ppc64 kernels using 32 bits userland (I haven't had a chance to test a
64 bits userland yet, but the implementation didn't change and was
tested earlier). I haven't tested yet the new functions.

Since the udbg code in ppc64 has no ppc32 equivalent, move it straight
over into arch/powerpc (and include/asm-powerpc for udbg.h).  In time,
we probably want to meld the various bits and pieces of 32-bit early
debugging code into udbg, but for now only include it on
CONFIG_PPC64=y builds.  The only change during the move is to
standardise the protecting #ifdef/#define in udbg.h, and move its
banner comment above the initial #ifdef (which seems to be normal
practice).

Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64).  Built
for 32bit multiplatform (ARCH=powerpc).

Convert to sparsemem and remove all the discontigmem code in the
process. This has a few advantages:

- The old numa_memory_lookup_table can go away
- All the arch specific discontigmem magic can go away

We also remove the triple pass of memory properties and instead create a
list of per node extents that we iterate through. A final cleanup would
be to change our lmb code to store extents per node, then we can reuse
that information in the numa code.
