+From 6ebf6c4f9e5ebca123a5b5f24afe67cf0473cf92 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] m68k: fix build
+
+When <sys/reg.h> is included after <linux/ptrace.h>, the build fails
+on m68k with the following diagnostics:
+
+ In file included from /usr/include/linux/ptrace.h:101:0,
+ from ptrace.h:51,
+ from sigreturn.c:2:
+ /usr/include/m68k-linux-gnu/sys/reg.h:26:3: error: expected identifier
+ before numeric constant
+ PT_D1 = 0,
+ ^
+
+Apparently, the only architecture where strace needs definitions
+provided by <sys/reg.h> is x86_64, other three (m68k, tile, and x86)
+are fine with definitions already provided by <linux/ptrace.h>.
+
+Fix the issue by getting rid of <sys/reg.h> and defining necessary
+macros in linux/x86_64/arch_regs.h file.
+
+* configure.ac (AC_CHECK_HEADERS): Remove sys/reg.h.
+* regs.h: Do not include <sys/reg.h>.
+* linux/x86_64/arch_regs.h (R15, R14, R13, R12, RBP, RBX, R11, R10,
+R9, R8, RAX, RCX, RDX, RSI, RDI, ORIG_RAX, RIP, CS, EFLAGS, RSP, SS,
+FS_BASE, GS_BASE, DS, ES, FS, GS): New macros.
+* NEWS: Mention this fix.
+
+Fixes: v4.21~21 ("Include <sys/ptrace.h> early")
+[baruch: drop the NEWS and configure.ac hunks]
