ARC: dw2 unwind: add infrastructure for adding cfi pseudo ops to asm

2016-09-30T21:48:22+00:00

1. detect whether binutils supports the cfi pseudo ops 2. define conditional macros to generate the ops 3. define new ENTRY_CFI/END_CFI to annotate hand asm code. - Needed because we don't want to emit dwarf info in general ENTRY/END used by lowest level trap/exception/interrutp handlers as unwinder gets confused trying to unwind out of them. We want unwinder to instead stop when it hits onfo those routines - These provide minimal start/end cfi ops assuming routine doesn't touch stack memory/regs Signed-off-by: Vineet Gupta

ARC: switch to generic ENTRY/END assembler annotations

2014-03-26T09:01:28+00:00

With commit 9df62f054406 "arch: use ASM_NL instead of ';'" the generic macros can handle the arch specific newline quirk. Hence we can get rid of ARC asm macros and use the "C" style macros. Signed-off-by: Vineet Gupta

arch: use ASM_NL instead of ';' for assembler new line character in the macro

2014-01-27T20:45:29+00:00

For some assemblers, they use another character as newline in a macro (e.g. arc uses '`'), so for generic assembly code, need use ASM_NL (a macro) instead of ';' for it. Signed-off-by: Chen Gang Acked-by: Vineet Gupta Signed-off-by: Michal Marek

ARC: Fundamental ARCH data-types/defines

2013-02-11T14:30:34+00:00

* L1_CACHE_SHIFT * PAGE_SIZE, PAGE_OFFSET * struct pt_regs, struct user_regs_struct * struct thread_struct, cpu_relax(), task_pt_regs(), start_thread(), ... * struct thread_info, THREAD_SIZE, INIT_THREAD_INFO(), TIF_*, ... * BUG() * ELF_* * Elf_* To disallow user-space visibility into some of the core kernel data-types such as struct pt_regs, #ifdef __KERNEL__ which also makes the UAPI header spit (further patch in the series) to NOT export it to asm/uapi/ptrace.h Signed-off-by: Vineet Gupta Cc: Jonas Bonn Cc: Al Viro Acked-by: Arnd Bergmann
