Subject: powerpc: Implement GET_IP/SET_IP
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=e62894273c7572cb1bec39096df605f42a66e964;p=~shefty%2Frdma-dev.git

powerpc: Implement GET_IP/SET_IP

With this change, helpers such as instruction_pointer() et al, get defined
in the generic header in terms of GET_IP

Removed the unnecessary definition of profile_pc in !CONFIG_SMP case as
suggested by Mike Frysinger.
