+Subject: [PATCH] mips: Use hardcodes values for ABI syscall bases
+
+mips kernels 5.13+ have stopped exposing the UAPIs which provided these
+defines, the values are more or less static so just use the hardcoded
+values for now. Use __NR_syscalls to get number of syscalls supported
+and include asm-generic/unistd.h to get this definition
