From a2492ca86c98f676561f7d318b1e2e1786af0caf Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Fri, 23 Jun 2023 23:03:20 -0700 Subject: riscv: Select HAVE_ARCH_USERFAULTFD_MINOR This allocates the VM flag needed to support the userfaultfd minor fault functionality. Because the flag bit is >= bit 32, it can only be enabled for 64-bit kernels. See commit 7677f7fd8be7 ("userfaultfd: add minor fault registration mode") for more information.
