+From: Benjamin Barenblat <bbaren@google.com>
+Subject: Use absl::uint128 for AES random number generator
+Forwarded: yes
+Applied-Upstream: https://github.com/abseil/abseil-cpp/commit/b06e719ee985ecd63e0dffbc68499549216f817f
+
+Replace randen’s internal 128-bit integer struct, u64x2, with
+absl::uint128. This eliminates some code and improves support for
+big-endian platforms.
+
+The author works at Google. Upstream applied this patch as Piper
+revision 383475671 and exported it to GitHub; the Applied-Upstream URL
+above points to the exported commit.

+Subject: Make randen_slow endian-correct
+Forwarded: yes
+Applied-Upstream: https://github.com/abseil/abseil-cpp/commit/33541e751039a8c4bd3a395dd1a3a0928885814a
+
+Pay attention to the platform endianness when pulling bytes out of each
+AES block, and use platform-endian round keys.
+
+The author works at Google. Upstream applied this patch as Piper
+revision 383878281 and exported it to GitHub; the Applied-Upstream URL
+above points to the exported commit.

+Subject: Also use uint8_t golden values in randen_test.cc
+Forwarded: yes
+Origin: upstream, https://github.com/abseil/abseil-cpp/commit/cc413f8b674d61e3aa948386432e526e051afca0
+
+Also use uint8_t golden values in randen_test.cc
+    
+This makes randen_test, randen_slow_test, and randen_hwaes_test essentially
+identical, as is the intent.
+
+The author works at Google. Upstream applied this patch as Piper
+revision 405484423 and exported it to GitHub; the Applied-Upstream URL
+above points to the exported commit.
