x86/kexec: fix very old regression and make compatible with modern Linux
References: bnc#619122
c/s 13829 lost the (32-bit only) cpu_has_pae argument passed to the
primary kernel's stub (in the 32-bit Xen case only), and Linux
2.6.27/.30 (32-/64-bit) introduced a new argument (for KEXEC_JUMP)
which for now simply gets passed a hardcoded value.
