From 42f355ef59a2f98fa4affb4265d3ba3e2d86baf1 Mon Sep 17 00:00:00 2001 From: Richard Guy Briggs Date: Wed, 19 May 2021 16:00:20 -0400 Subject: audit: replace magic audit syscall class numbers with macros Replace audit syscall class magic numbers with macros. This required putting the macros into new header file include/linux/audit_arch.h since the syscall macros were included for both 64 bit and 32 bit in any compat code, causing redefinition warnings.
