Set ARCH_SUPPORTS_SPECULATIVE_PAGE_FAULT for BOOK3S_64. This enables the Speculative Page Fault handler. Support is only provide for BOOK3S_64 currently because: - require CONFIG_PPC_STD_MMU because checks done in set_access_flags_filter() - require BOOK3S because we can't support for book3e_hugetlb_preload() called by update_mmu_cache() Cc: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Laurent Dufour <ldufour@linux.ibm.com> --- arch/powerpc/Kconfig | 1 + 1 file changed, 1 insertion(+)
