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")
