Currently x86's get_sigframe() checks for "current->sas_ss_size"
to determine whether there is a need to switch to sigaltstack.
The common practice used by all other arches is to check for
sas_ss_flags(sp) == 0

This patch makes the code consistent with other arches and also
allows for the further sigaltstack improvements within this patch serie.
You've duplicate part of the check. That whole block is already
checking !sigstack. Can you remove that now?
OK.
