To: paulus; +Cc: linuxppc-dev
From: Masakazu Mokuno <mokuno@sm.sony.co.jp>
Rework the PS3 htab code to remove the need to ioremap the hash table
by using the HV calls lv1_insert_htab_entry() and
lv1_read_htab_entries().
This fixes a runtime failure on the PS3 introduced by the powerpc
ioremap_prot rework of commit a1f242ff460e4b50a045fa237c3c56cce9eabf83.
