From 6c81fe7925cc4c42de49e17be21eb86d1173c3a7 Mon Sep 17 00:00:00 2001 From: Larry Bassel Date: Fri, 30 May 2014 12:34:15 -0700 Subject: arm64: enable context tracking Make calls to ct_user_enter when the kernel is exited and ct_user_exit when the kernel is entered (in el0_da, el0_ia, el0_svc, el0_irq and all of the "error" paths). These macros expand to function calls which will only work properly if el0_sync and related code has been rearranged (in a previous patch of this series). The calls to ct_user_exit are made after hw debugging has been enabled (enable_dbg_and_irq). The call to ct_user_enter is made at the beginning of the kernel_exit macro. This patch is based on earlier work by Kevin Hilman. Save/restore optimizations were also done by Kevin.
