Mike Rapoport 0cfc8a8d70 sparc32: fix page table traversal in srmmu_nocache_init()
The srmmu_nocache_init() uses __nocache_fix() macro to add an offset to
page table entry to access srmmu_nocache_pool.

But since sparc32 has only three actual page table levels, pgd, p4d and
pud are essentially the same thing and pgd_offset() and p4d_offset() are
no-ops, the __nocache_fix() should be done only at PUD level.

Remove __nocache_fix() for p4d_offset() and pud_offset() and keep it
only for PUD and lower levels.

Fixes: c2bc26f7ca ("sparc32: use PUD rather than PGD to get PMD in srmmu_nocache_init()")
