It is counter intuitive to have the select listed
as part of the PCI option.
Move the select to the SPARC64 specific part of the config.
PCI_MSI has a dependency on PCI so it does not harm to have
it always selected.

While doing this use standard names for start/end
so we could use definitions straight from asm-generic
for all the typical symbols.
This also allowed us to drop the use of PROVIDE in the linker
script so sprc is less non-standard on this area.

Use a dedicated aligned section for the init_thread_union
variable and declare this section in vmlinux.lds.
This align sparc with most other architectures. Eventually this allow
the init_task bits to be unified across all architectures.

In order to always provide fully synchronized state to the debugger,
we might need to do a synchronize_user_stack().
A pair of hooks, arch_ptrace_stop_needed() and arch_ptrace_stop(),
exist to handle this kind of situation. It was created for
the sake of IA64.
Use them, to flush the kernel side cached register windows
to the user stack, when necessary.

Use sparc64 version of scatterlist.h.
There are three main differences:
dma_addr_t replaces __u32
dma_address replaces dvma_address
dma_length replaces dvma_length
dma_addr_t is a u32 on sparc32.

Without fancy makefile rules it's not straightforward
to prevent both arch/sparc/kernel/audit.o and lib/audit.o
from both being used on sparc32.
Since arch/sparc/kernel/audit.c is identical to lib/audit.c
except some CONFIG_COMPAT protected sections of code, just
use it on sparc32 too as that's the simplest way to fix
this.
