From: Andy Lutomirski Date: Fri, 5 Sep 2014 22:13:52 +0000 (-0700) Subject: x86, x32, audit: Fix x32's AUDIT_ARCH wrt audit X-Git-Tag: upstream/snapshot3+hdmi~17^2~100 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=406ad132276e8207e1700744d767aa80121b87ea;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git x86, x32, audit: Fix x32's AUDIT_ARCH wrt audit commit 81f49a8fd7088cfcb588d182eeede862c0e3303e upstream. is_compat_task() is the wrong check for audit arch; the check should be is_ia32_task(): x32 syscalls should be AUDIT_ARCH_X86_64, not AUDIT_ARCH_I386. CONFIG_AUDITSYSCALL is currently incompatible with x32, so this has no visible effect.
