+Subject: [PATCH] linux-serial-test.c: fix missing CMSPAR define on MIPS
+
+This patch is an adaptation of
+https://git.busybox.net/buildroot/diff/package/freerdp/0003-add-missing-define.patch?id=78cd32631e959e04b1a2f18be7b0757e21482438
+
+linux-serial-test.c uses CMSPAR, which is defined by glibc in
+bits/termios.h.
+
+glibc has two flavours of bits/termios.h: a generic one and an
+architecture-specific one. When installing, glibc will install the
+architecture-specific file if it exists, otherwise it installs the
+generic file. Only Alpha, MIPS, PPC and Sparc have their own
+bits/termios.h.
+
+The generic bits/termios.h, as well as the Alpha, PPC and Sparc flavours
+do define CMSPAR. However, the MIPS flavour does not define it.
+
+Define CMSPAR to the value from the generic value, which is also the
+value known to the Linux kernel for MIPS.
