Most definitions of current_text_addr were the same as _THIS_IP_, but a few archs had inline assembly instead. This patch removes the final call site of current_text_addr, making all of the definitions dead code. Signed-off-by: Nick Desaulniers --- I suspect that current_text_addr predated GNU C extensions for statement expressions and/or taking the address of a label, then the macro was reimplemented for every new archs include/asm/processor.h, even though there were very few call sites, and none required an assembly implementation vs the C implementation. I am sad to see a few neat arch specific ways of getting the ip/pc, but we should prefer the higher level C in cases where assembly is not required. And the definitions can always be found again in git history. arch/alpha/include/asm/processor.h | 6 ------ arch/arc/include/asm/processor.h | 8 -------- arch/arm/include/asm/processor.h | 6 ------ arch/arm64/include/asm/processor.h | 7 ------- arch/c6x/include/asm/processor.h | 11 ----------- arch/h8300/include/asm/processor.h | 6 ------ arch/hexagon/include/asm/processor.h | 3 --- arch/ia64/include/asm/processor.h | 6 ------ arch/m68k/include/asm/processor.h | 6 ------ arch/microblaze/include/asm/processor.h | 12 ------------ arch/mips/include/asm/processor.h | 5 ----- arch/nds32/include/asm/processor.h | 6 ------ arch/nios2/include/asm/processor.h | 6 ------ arch/openrisc/include/asm/processor.h | 5 ----- arch/parisc/include/asm/processor.h | 11 ----------- arch/powerpc/include/asm/processor.h | 6 ------ arch/riscv/include/asm/processor.h | 6 ------ arch/s390/include/asm/processor.h | 6 ------ arch/sh/include/asm/processor_32.h | 6 ------ arch/sh/include/asm/processor_64.h | 15 --------------- arch/sparc/include/asm/processor_32.h | 6 ------ arch/sparc/include/asm/processor_64.h | 6 ------ arch/unicore32/include/asm/processor.h | 6 ------ arch/x86/include/asm/kexec.h | 3 ++- arch/x86/include/asm/processor.h | 12 ------------ arch/x86/um/asm/processor_32.h | 8 -------- arch/x86/um/asm/processor_64.h | 3 --- arch/xtensa/include/asm/processor.h | 8 -------- 28 files changed, 2 insertions(+), 193 deletions(-) diff --git a/arch/alpha/include/asm/processor.h b/arch/alpha/include/asm/processor.h index cb05d045efe3..6100431da07a 100644 --- a/arch/alpha/include/asm/processor.h +++ b/arch/alpha/include/asm/processor.h @@ -10,12 +10,6 @@ #include /* for ADDR_LIMIT_32BIT */ -/* - * Returns current instruction pointer ("program counter"). - */ -#define current_text_addr() \ - ({ void *__pc; __asm__ ("br %0,.+4" : "=r"(__pc)); __pc; }) - /* * We have a 42-bit user address space: 4TB user VM... */ diff --git a/arch/arc/include/asm/processor.h b/arch/arc/include/asm/processor.h index 8ee41e988169..10346d6cf926 100644 --- a/arch/arc/include/asm/processor.h +++ b/arch/arc/include/asm/processor.h @@ -98,14 +98,6 @@ extern void start_thread(struct pt_regs * regs, unsigned long pc, extern unsigned int get_wchan(struct task_struct *p); -/* - * Default implementation of macro that returns current - * instruction pointer ("program counter"). - * Should the PC register be read instead ?
