-This patch is taken from Debian instead of the upstream URL because the
-upstream URL contains far more changes than occur in this patch.
-
-It was then modified to also work for armhf.
-
-From: Benjamin Barenblat <bbaren@google.com>
-Subject: Ignore missing CPU frequency on more architectures
-Forwarded: yes
-Applied-Upstream: https://github.com/abseil/abseil-cpp/commit/1918ad2ae38aa32c74b558b322479a8efdd76363
-
-Linux on MIPS, PA-RISC, RISC-V, and SystemZ doesn’t expose the nominal CPU
-frequency via /sys, so don’t worry if `NominalCPUFrequency` returns 1.0 on those
-platforms.
-
-Some POWER machines expose the CPU frequency; others do not. Since we can’t
-predict which type of machine the tests will run on, simply disable testing for
-`NominalCPUFrequency` on POWER.
-
-The author works at Google. Upstream applied this patch as Piper revision
-347079873 and exported it to GitHub; the Applied-Upstream URL above points to
-the exported commit.
