From 499b5d176a77773cab5479264a3d5067176df21c Mon Sep 17 00:00:00 2001 From: Timothy E Baldwin Date: Thu, 12 May 2016 18:47:29 +0100 Subject: linux-user: Renumber TARGET_QEMU_ESIGRETURN, make it not arch-specific Currently we define a QEMU-internal errno TARGET_QEMU_ESIGRETURN only on the MIPS and PPC targets; move this to errno_defs.h so it is available for all architectures, and renumber it to 513. We pick 513 because this is safe from future use as a system call return value: Linux uses it as ERESTART_NOINTR internally and never allows that errno to escape to userspace.
