Subject: [PATCH v7 03/24] powerpc/mm: Define CONFIG_SPECULATIVE_PAGE_FAULT
Date: Tue,  6 Feb 2018 17:49:49 +0100	[thread overview]
Message-ID: <1517935810-31177-4-git-send-email-ldufour@linux.vnet.ibm.com> (raw)
In-Reply-To: <1517935810-31177-1-git-send-email-ldufour@linux.vnet.ibm.com>

Define CONFIG_SPECULATIVE_PAGE_FAULT for BOOK3S_64 and SMP. 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()
