5bc0530893 sparc: move select of ARCH_SUPPORTS_MSI
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.

86ed40bd6f sparc: unify sections.h
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.

878a553595 sparc: We need to implement arch_ptrace_stop().
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.

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.
