sparc: unify ptrace.h
The two ptrace.h implementations are very alike but the small differences required two set of ifdef/else/endif pairs. The definition of reg_window32 could have been shared but that would have required several updates in sparc32 code as all printk formatting for example assume it is longs. sparc_stackf looked like anohter candidate to share if the 32 bit was renamed to sparc_stackf32. But it contains two pointers in the sparc32 version which would have been 64 bit in the sparc64 version so it was non-trivial. Using a set of accessor macros could do the trick if pursued later. The sparc64 specific definitions are not protected by ifdef - as it should not be required to do so. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
