'Restructure architecture specific code' series (now merged in char-misc) introduced a regression wrt kexec/kdump. Hypercall and TSC pages setup was moved out to the architecture specific code and the cleanup was dropped. We, however, still need this cleanup: in kexec case the new kernel may try using these pages as normal memory and will certainly crash. Restore the minimal cleanup moving it to the architecture specific code. Commit ids I mention in 'Fixes:' tags are from char-misc-next.
