powerpc/pkeys: Fix build error with PPC_MEM_KEYS disabled
IS_ENABLED() instead of #ifdef still requires variable declaration. In this specific case, default_uamor is declared in asm/pkeys.h which is only included if PPC_MEM_KEYS is enabled. arch/powerpc/mm/book3s64/hash_utils.c: In function ‘hash__early_init_mmu_secondary’: arch/powerpc/mm/book3s64/hash_utils.c:1119:21: error: ‘default_uamor’ undeclared (first use in this function) 1119 | mtspr(SPRN_UAMOR, default_uamor); | ^~~~~~~~~~~~~ Fixes: 6553fb799f60 ("powerpc/pkeys: Fix boot failures with Nemo board (A-EON AmigaOne X1000)") Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20200817103301.158836-1-aneesh.kumar@linux.ibm.com
