From d3c1cfcdb43e023ab1b1c7a555cd9e929026500a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20P=C3=A4rtel?= Date: Thu, 2 Aug 2012 00:49:17 +0200 Subject: um: pass siginfo to guest process MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit UML guest processes now get correct siginfo_t for SIGTRAP, SIGFPE, SIGILL and SIGBUS. Specifically, si_addr and si_code are now correct where previously they were si_addr = NULL and si_code = 128.
