system_call_after_swapgs doesn't really benefit from forcing alignment from it - quite the opposite, native code needlessly so far got a big NOP instruction inserted in front of it. Xen being the only user of the separate entry point can well live with the branch going to three bytes into a cache line. The compatibility mode ptregs entry points for one can make use of the GLOBAL() macro, and should be suitably aligned. Their shared continuation point (ia32_ptregs_common) otoh doesn't need to be global at all, but should continue to be properly aligned.
