77d10d0e63 sparc64: Fix sparse warnings in pci.c
1) Declare pci_poke_* in pci_impl.h
2) of_create_pci_dev() should be static
3) ->setup_msi_irq() wants an unsigned int pointer not a plain
   int one
4) void value expression return in arch_teardown_msi_irq()

b0f1e7962f sparc64: Define WANT_PAGE_VIRTUAL
As sparse warns, without this struct page pointer subtraction is
extremely expensive, and this is a pretty common operation in
fast paths.

With this define struct page becomes 64 bytes which makes for a
simple subtract and shift, instead of a costly divide or reciprocol
multiply.

4845afac95 sparc64: Add __arch64__ to CHECKFLAGS
Otherwise sparse doesn't work.  The 32 vs. 64 header ifdef
used under arch/sparc/include/asm/ is:
