cfbddd0d0b sparc64: fix sparse warning in prom_64.c
Fix following warning:
prom_64.c:376:6: warning: symbol 'arch_find_n_match_cpu_physical_id' was not declared. Should it be static?

Add missing include to pick up prototype.
Rearrange includes to use the inverse christmas tree structure.

070826820d sparc64, sched: Remove unused sparc64_multi_core
Remove sparc64_multi_core because it's not used any more.

It was added by a2f9f6bbb3 ("Fix {mc,smt}_capable()"), and the last uses
were removed by e637d96bf462 ("sched: Remove unused mc_capable() and
smt_capable()").

d1cb9d1af0 of: Make cpu node handling more portable.
Use for_each_node_by_type() to iterate all cpu nodes in the
system.

Provide and overridable function arch_find_n_match_cpu_physical_id,
which sees if the given device node matches 'cpu' and if so sets
'*thread' when non-NULL to the cpu thread number within the core.

The default implementation behaves the same as the existing code.

Add a sparc64 implementation.

5da444aae5 sparc: fix format string argument for prom_printf()
prom_printf() takes printf style arguments.  Specifing GCC's format
attribute reveals that there are several wrong usages of prom_printf().

This fixes those wrong format strings and arguments, and also leaves
format attributes in order to detect similar mistakes at compile time.

cdd0b0ac12 sparc: remove several unnecessary module.h include instances
Building an allyesconfig doesn't reveal a hidden need
for any of these.  Since module.h brings in the whole kitchen
sink, it just needlessly adds 30k+ lines to the cpp burden.

      FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

      sed -i \

        M=$(echo $N | sed 's/lmb/memblock/g')
        mv $N $M
      done

and remove some wrong change like lmbench and dlmb etc.

also move memblock.c from lib/ to mm/

89229071c0 cpumask: Use accessors code.: sparc64
Impact: use new API

Use the accessors rather than frobbing bits directly.  Most of this is
in arch code I haven't even compiled, but is straightforward.

Add final len assignment in sparc64's get_one_property() (it's necessary
to avoid unchecked return value warnings on the sparc32 side),
and mark name argument const on sparc32's copy.

b9e5567cda sparc: Move property building code into prom_common.c
Unfortunately there is some sparc32/sparc64 ifdef'ery in
here due to the difference in how the prom_firstprop()
and prom_nextprop() routines work.

This will be eliminated eventually.

a88b5ba8bd sparc,sparc64: unify kernel/
o Move all files from sparc64/kernel/ to sparc/kernel
  - rename as appropriate
o Update sparc/Makefile to the changes
o Update sparc/kernel/Makefile to include the sparc64 files

NOTE: This commit changes link order on sparc64!

Link order had to change for either of sparc32 and sparc64.
And assuming sparc64 see more testing than sparc32 change link
order on sparc64 where issues will be caught faster.
