+Subject: [PATCH] Fix invalid sigprocmask call
+
+The POSIX document says
+
+    The pthread_sigmask() and sigprocmask() functions shall fail if:
+
+    [EINVAL]
+    The value of the how argument is not equal to one of the defined values.
+
+and this is how musl-libc is currently doing.  Fix the call to be safe
+and correct

+Subject: [PATCH] use <asm/sgidefs.h>
+
+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.

+Subject: [PATCH] mips-linux-nat: Define _ABIO32 if not defined
+
+This helps building gdb on mips64 on musl, since
+musl does not provide sgidefs.h this define is
+only defined when GCC is using o32 ABI, in that
+case gcc emits it as built-in define and hence
+it works ok for mips32
