From 47b2c3fff4932e6fc17ce13d51a43c6969714e20 Mon Sep 17 00:00:00 2001 From: Bilal Amarni Date: Thu, 8 Jun 2017 14:47:26 +0100 Subject: security/keys: add CONFIG_KEYS_COMPAT to Kconfig CONFIG_KEYS_COMPAT is defined in arch-specific Kconfigs and is missing for several 64-bit architectures : mips, parisc, tile. At the moment and for those architectures, calling in 32-bit userspace the keyctl syscall would return an ENOSYS error. This patch moves the CONFIG_KEYS_COMPAT option to security/keys/Kconfig, to make sure the compatibility wrapper is registered by default for any 64-bit architecture as long as it is configured with CONFIG_COMPAT.
