sh: Fix up PUD trampling in ranged page table init for X2TLB. page_table_range_init() presently allocates a PUD page for the 3-level page table case on X2 TLB configurations on each successive call. This results in the previous PUD page being trampled when PMDs with an overlapping PUD are initialized. This case was triggered by putting persistent kmaps immediately below the fixmap range for highmem. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
