From eaca6eae3e0c41d41fcb9d1d70e00934988dff2e Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 25 Nov 2012 23:12:10 -0500 Subject: sanitize rt_sigaction() situation a bit Switch from __ARCH_WANT_SYS_RT_SIGACTION to opposite (!CONFIG_ODD_RT_SIGACTION); the only two architectures that need it are alpha and sparc. The reason for use of CONFIG_... instead of __ARCH_... is that it's needed only kernel-side and doing it that way avoids a mess with include order on many architectures.
