#     powerpc/6xx: fix setup and use of SPRN_SPRG_PGDIR for hash32
#     
#     Not only the 603 but all 6xx need SPRN_SPRG_PGDIR to be initialised at
#     startup. This patch move it from __setup_cpu_603() to start_here()
#     and __secondary_start(), close to the initialisation of SPRN_THREAD.
#     
#     Previously, virt addr of PGDIR was retrieved from thread struct.
#     Now that it is the phys addr which is stored in SPRN_SPRG_PGDIR,
#     hash_page() shall not convert it to phys anymore.
#     This patch removes the conversion.
#     
#     Fixes: 93c4a162b014 ("powerpc/6xx: Store PGDIR physical address in a SPRG")
