>From 5b48b64319463a4ccab560304ce3cf72c71d081d Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Tue, 21 Feb 2012 14:45:52 +0100 Subject: [PATCH] x86-64: Fix CFI data for common_interrupt Commit eab9e6 "x86-64: Fix CFI data for interrupt frames" introduced a DW_CFA_def_cfa_expression in the SAVE_ARGS_IRQ macro. To later define the CFA using a simple register+offset rule both register and offset need to be supplied. Just using CFI_DEF_CFA_REGISTER leaves the offset undefined. So use CFI_DEF_CFA with reg+off explicitly at the end of common_interrupt.
