From ee1bc694fbaec1a662770703fc34a74abf418938 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Sun, 25 Apr 2021 21:58:31 +1000 Subject: [PATCH] powerpc/kvm: Fix build error when PPC_MEM_KEYS/PPC_PSERIES=n lkp reported a randconfig failure: In file included from arch/powerpc/include/asm/book3s/64/pkeys.h:6, from arch/powerpc/kvm/book3s_64_mmu_host.c:15: arch/powerpc/include/asm/book3s/64/hash-pkey.h: In function 'hash__vmflag_to_pte_pkey_bits': >> arch/powerpc/include/asm/book3s/64/hash-pkey.h:10:23: error: 'VM_PKEY_BIT0' undeclared 10 | return (((vm_flags & VM_PKEY_BIT0) ? H_PTE_PKEY_BIT0 : 0x0UL) | | ^~~~~~~~~~~~ We added the include of book3s/64/pkeys.h for pte_to_hpte_pkey_bits(), but that header on its own should only be included when PPC_MEM_KEYS=y. Instead include linux/pkeys.h, which brings in the right definitions when PPC_MEM_KEYS=y and also provides empty stubs when PPC_MEM_KEYS=n.
