The pages backing page-table allocations for SRMMU are allocated via memblock as part of the "nocache" region initialisation during srmmu_paging_init() and should not be freed even if a later call to pgtable_pte_page_ctor() fails. Remove the broken call to __free_page(). Cc: David S. Miller <davem@davemloft.net> Cc: Kirill A.
