[PATCH] powerpc/40x: Always fault when _PAGE_ACCESSED is not set

The kernel expects pte_young() to work regardless of CONFIG_SWAP. Make sure a minor fault is taken to set _PAGE_ACCESSED when it is not already set, regardless of the selection of CONFIG_SWAP. Fixes: 2c74e2586bb9 ("powerpc/40x: Rework 40x PTE access and TLB miss") Cc: sta...@vger.kernel.org Signe
