If we use jump table in module init, there are marked as removed in __jump_table section after init is done. But we already applied ro permissions on the module, so we can't modify a read only section (crash in remove_jump_label_module_init). Make the __jump_table section rw.

ea530692 made a CPU use monitor/mwait when offline. This is not the optimal choice for AMD wrt to powersavings and we'd prefer our cores to halt (i.e. enter C1) instead. For this, the same selection whether to use monitor/mwait has to be used as when we select the idle routine for the machine. With this patch, offlining cores 1-5 on a X6 machine allows core0 to boost again.

This reverts commit 86b1e8dd ("x86: Make relocatable kernel work with new binutils"). Markus Trippelsdorf reported a boot failure caused by this patch.
