removes extra hassle of setting up -cpu to match required
feature. My MTE test continue working fine and require one less configuration
option - undeniable improvement in user experience!

This is often because .free_lppacas lacks a __initdata
annotation or the annotation of lppaca_size is wrong.
Fix it by using proper annotation for free_lppacas. Additionally, annotate
{allocate,new}_llpcas properly.

.free_area_init_core.isra.47() references a function __init
.set_pageblock_order(). If .set_pageblock_order is only used by
.free_area_init_core.isra.47 then annotate .set_pageblock_order with a
matching annotation.
Fix it by proper annotation of prom_rtas_call.
