+Subject: gdb-rhbz1932645-aarch64-ptrace-header-order.patch
+
+;; [aarch64] Backport fix for aarch64-linux-hw-point.c build problem
+;; (RH BZ 1932645).
+
+Fix aarch64-linux-hw-point.c build problem
+
+Due to a recent glibc header file change, the file
+nat/aarch64-linux-hw-point.c no longer builds on Fedora rawhide.
+
+An enum for PTRACE_SYSEMU is now provided by <sys/ptrace.h>.  In the
+past, PTRACE_SYSEMU was defined only in <asm/ptrace.h>.  This is
+what it looks like...
+
+In <asm/ptrace.h>:
+
+ #define PTRACE_SYSEMU		  31
+
+In <sys/ptrace.h>:
+
+enum __ptrace_request
+{
+  ...
+  PTRACE_SYSEMU = 31,
+ #define PT_SYSEMU PTRACE_SYSEMU
+
+  ...
+}
+
+When <asm/ptrace.h> and <sys/ptrace.h> are both included in a source
+file, we run into the following build problem when the former is
+included before the latter:
+
+In file included from nat/aarch64-linux-hw-point.c:26:
+/usr/include/sys/ptrace.h:86:3: error: expected identifier before numeric constant
+   86 |   PTRACE_SYSEMU = 31,
+      |   ^~~~~~~~~~~~~
+
+(There are more errors after this one too.)
+
+The file builds without error when <asm/ptrace.h> is included after
+<sys/ptrace.h>.  I found that this is already done in
+nat/aarch64-sve-linux-ptrace.h (which is included by
+nat/aarch64-linux-ptrace.c).
+
+I've tested this change on Fedora rawhide and Fedora 33, both
+running on an aarch64 machine.
