powerpc: Revert the initial stack protector support
Unfortunately the stack protector support we merged recently only works on some toolchains. If the toolchain is built without glibc support everything works fine, but if glibc is built then it leads to a panic at boot. The solution is not rc5 material, so revert the support for now. This reverts commits: 6533b7c16ee5 ("powerpc: Initial stack protector (-fstack-protector) support") 902e06eb86cd ("powerpc/32: Change the stack protector canary value per task") Fixes: 6533b7c16ee5 ("powerpc: Initial stack protector (-fstack-protector) support") Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

intersection between mempolicy and cpuset. I would expect the nodemask adjustment for saving overhead in g_p_f(), but that clearly doesn't happen in the current form. So we have both crazy complexity and overhead, AFAICS.

We check the zoneref pointer which is never NULL and we should check the zone pointer. Also document this in first_zones_zonelist() comment per Michal Hocko.
