From 74fca9da097b74117ae2cef9e5f0d9b0e28ccbb7 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Wed, 15 Sep 2010 11:16:08 -0400 Subject: arch/tile: Change struct sigcontext to be more useful Rather than just using pt_regs, it now contains the actual saved state explicitly, similar to pt_regs. By doing it this way, we provide a cleaner API for userspace (or equivalently, we avoid the need for libc to provide its own definition of sigcontext). While we're at it, move PT_FLAGS_xxx to where they are not visible from userspace. And always pass siginfo and mcontext to signal handlers, even if they claim they don't need it, since sometimes they actually try to use it anyway in practice.
