Christophe Leroy 03d701c2d9 powerpc/32s: Don't use SPRN_SPRG_PGDIR in hash_page 
SPRN_SPRG_PGDIR is there mainly to speedup SW TLB miss handlers
for powerpc 603.

We need to free SPRN_SPRG2 to reduce the mess with CONFIG_VMAP_STACK.

In hash_page(), reading PGDIR from thread_struct will be in the noise
performance wise.
