Hence make KUAP a BOOK3S_64 feature. Also make it a subfeature of PPC_MEM_KEYS. Hash translation is going to use pkeys to support KUAP/KUEP. Adding this dependency reduces the code complexity and enables us to move some of the initialization code to pkeys.c Signed-off-by: Aneesh Kumar K.V --- arch/powerpc/platforms/Kconfig.cputype | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/powerpc/platforms/Kconfig.cputype b/arch/powerpc/platforms/Kconfig.cputype index 0c3c1902135c..8100d5c0812d 100644 --- a/arch/powerpc/platforms/Kconfig.cputype +++ b/arch/powerpc/platforms/Kconfig.cputype @@ -99,6 +99,8 @@ config PPC_BOOK3S_64 select ARCH_SUPPORTS_NUMA_BALANCING select IRQ_WORK select PPC_MM_SLICES + select PPC_HAVE_KUAP if PPC_MEM_KEYS + select PPC_HAVE_KUEP if PPC_MEM_KEYS config PPC_BOOK3E_64 bool "Embedded processors" @@ -350,8 +352,6 @@ config PPC_RADIX_MMU bool "Radix MMU Support" depends on PPC_BOOK3S_64 select ARCH_HAS_GIGANTIC_PAGE - select PPC_HAVE_KUEP - select PPC_HAVE_KUAP default y help Enable support for the Power ISA 3.0 Radix style MMU.
