+Subject: [PATCH 11/11] gdbserver ctrl-c handling
+
+This problem was created by the upstream commit 78708b7c8c
+After applying the commit, it will send SIGINT to the process
+group(-signal_pid).
+But if we use gdbserver send SIGINT, and the attached process is not a
+process
+group leader, then the "kill (-signal_pid, SIGINT)" returns error and
+fails  to
+interrupt the attached process.

+Build fix for MIPS with musl libc
+
+The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
+but not by musl. Regardless of the libc, the kernel headers provide
+<asm/sgidefs.h> which provides the same definitions, so use that
+instead.

+This helps building gdb on mips64 on musl, since
