For ARM only common parts were removed from and re-use generic do_bug_frame() for ARM. RISC-V will be switched to use and in the future, it will use common the version of do_bug_frame() when xen/common will work for RISC-V. --- Changes in V2: * Update cover letter. * Switch to x86 implementation as generic as it is more compact ( at least from the point of view of bug frame structure). * Put [PATCH v1 4/4] xen: change to as second patch, update the patch to change all to among the whole project to not break compilation. * Rename CONFIG_GENERIC_DO_BUG_FRAME to CONFIG_GENERIC_BUG_FRAME. * Change the macro bug_loc(b) to avoid the need for a cast: #define bug_loc(b) ((unsigned long)(b) + (b)->loc_disp) * Rename BUG_FRAME_STUFF to BUG_FRAME_STRUCT * Make macros related to bug frame structure more generic. * Rename bug_file() in ARM implementation to bug_ptr() as generic do_bug_frame() uses bug_ptr(). * Introduce BUG_INSTR and MODIFIER to make _ASM_BUGFRAME_TEXT reusable between x86 and RISC-V. * Rework do_invalid_op() in x86 ( re-use handle_bug_frame() and find_bug_frame() ) --- Oleksii Kurochko (4): xen: introduce CONFIG_GENERIC_BUG_FRAME xen: change to xen/arm: switch ARM to use generic implementation of bug.h xen/x86: switch x86 to use generic implemetation of bug.h xen/arch/arm/Kconfig | 1 + xen/arch/arm/include/asm/bug.h | 32 +----- xen/arch/arm/include/asm/div64.h | 2 +- xen/arch/arm/include/asm/traps.h | 2 - xen/arch/arm/traps.c | 79 ------------- xen/arch/arm/vgic/vgic-v2.c | 2 +- xen/arch/arm/vgic/vgic.c | 2 +- xen/arch/x86/Kconfig | 1 + xen/arch/x86/acpi/cpufreq/cpufreq.c | 2 +- xen/arch/x86/include/asm/asm_defns.h | 2 +- xen/arch/x86/include/asm/bug.h | 88 +-------------- xen/arch/x86/traps.c | 81 +++----------- xen/common/Kconfig | 3 + xen/common/Makefile | 1 + xen/common/bug.c | 113 +++++++++++++++++++ xen/drivers/cpufreq/cpufreq.c | 2 +- xen/include/xen/bug.h | 161 +++++++++++++++++++++++++++ xen/include/xen/lib.h | 2 +- 18 files changed, 306 insertions(+), 270 deletions(-) create mode 100644 xen/common/bug.c create mode 100644 xen/include/xen/bug.h
