+Subject: [PATCH] Fix build on riscv32
+
+Define __NR_mmap in terms of __NR_mmap2 and __NR_futex interms of
+__NR_futex_time64 for rv32, since there calls dont exist for rv32
+
+Also recognise rv32 as a new 32bit platform
+
+Upstream-Status: Submitted [https://github.com/abseil/abseil-cpp/pull/675]
