From 66f4e88cc69da7d9ec4d68cf370cc69742d4af81 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski <linux@dominikbrodowski.net> Date: Sun, 11 Mar 2018 11:34:38 +0100 Subject: x86/ioport: add ksys_ioperm() helper; remove in-kernel calls to sys_ioperm() Using this helper allows us to avoid the in-kernel calls to the sys_ioperm() syscall. The ksys_ prefix denotes that this function is meant as a drop-in replacement for the syscall. In particular, it uses the same calling convention as sys_ioperm(). This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined.
