Commit 4f9a58d7 ("increase
AT_VECTOR_SIZE to terminate saved_auxv properly") changes the size of
AT_VECTOR_SIZE from hard coded '44' to a calculation based on the value
of AT_VECTOR_SIZE_ARCH and AT_VECTOR_SIZE_BASE.

The change works for arch/powerpc, but it breaks arch/ppc because the
needed AT_VECTOR_SIZE_ARCH is not present in include/asm-ppc/system.h
and a default value of 0 is used instead.  This results in
AT_VECTOR_SIZE being too small and it causes a kernel crash on loading
init.

The BCM148 has 4 cores but there are also just 4 generic timers available
so use the ZBbus cycle counter instead of it.  In addition the ZBbus
counter also offers a much higher resolution and 64-bit counting so I'm
considering a later complete conversion to it once I figure out if all
members of the Sibyte SOC family support it - the docs seem to agree but
the headers files seem to disagree ...

Add a Kconfig entry which will toggle some sanity checks on the sg
entry and tables.
Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:

- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
  at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
  with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
  NULL when passed such an entry.

It's thus important that sg table users use the proper accessors to get
and set the page member.

make vmlinux would delete the content of $(MODVERDIR)
equals .tmp_versions. This caused a subsequent
make modules_install to fail.

Fix it so we clean the directory only for the
modules build - but we still unconditionally create it so
we can do:
make dir/file.ko
without a preceeding make modules.
