  To: linux-arch; +Cc: Carlos O'Donell


This patch continues to hang around at Morton manor.  last time it was
discussed Andi had issues with it and thing petered out.

Can we please wrap this up one ay or the other?



From: "Carlos O'Donell" <carlos@baldric.uwo.ca>

These changes allow 64-bit arches to copy siginfo_t to a 32-bit userspace in
a generic fashion.  All 64-bit arches with compat 32-bit tasks can take
advantage of the generic code.  hppa64 already uses this code, with ia64 and
ppc64 changes in the works.

Most arches use the asm-generic/siginfo.h definition.  For those arches with
64-bit platforms, and requiring compat with 32-bit tasks, we create a generic
layer for copying siginfo_t structures to userspace.  First we define the
required compat_ structures in include/asm-generic/compat_signal.h and in
include/linux/compat_siginfo.h.  The latter is not in asm-generic, because
doing so would require that all arches add an asm/compat_siginfo.h for the
generic code to work.

Next we implement a generic compat_copy_siginfo_to_user in
kernel/compat_signal.c.  To make use of the compat copy routine we add a
check in kernel/signal.c to determine if the task requires a compat copy, and
if so, call compat_copy_siginfo_to_user instead.
