powerpc/book3s_32: Fix build error with checkpoint restart
In file included from mm/vmscan.c:54:0: include/linux/swapops.h: In function ‘pte_to_swp_entry’: include/linux/swapops.h:69:2: error: implicit declaration of function ‘pte_swp_soft_dirty’ [-Werror=implicit-function-declaration] if (pte_swp_soft_dirty(pte)) ^ include/linux/swapops.h:70:3: error: implicit declaration of function ‘pte_swp_clear_soft_dirty’ [-Werror=implicit-function-declaration] pte = pte_swp_clear_soft_dirty(pte); We support soft dirty tracking only with book3s 64 for now. So change the Kconfig dependency accordingly. Also CHECKPOINT_RESTORE feature is not really dependent on SOFT_DIRTY. We track the dependency between MEM_SOFT_DIRTY and ARCH_SOFT_DIRTY through headers Fixes: 7207f43665b8 ("powerpc/mm: Add page soft dirty tracking") Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
