ptrace: use ptrace_request() in the remaining architectures
Use ptrace_request() in the three remaining architectures that didn't use it (m68knommu, h8300, microblaze). This means: - ptrace_request now handles PTRACE_{PEEK,POKE}{TEXT,DATA} and PTRACE_DETATCH calls that were previously called directly, or in case of h8300 even open coded. - adds new support for PTRACE_SETOPTIONS/PTRACE_GETEVENTMSG/ PTRACE_GETSIGINFO/PTRACE_SETSIGINFO Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Cc: Oleg Nesterov <oleg@redhat.com> Cc: Michal Simek <monstr@monstr.eu> Acked-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Roland McGrath <roland@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
