+For generic kernel features that need architecture support, the
+arch-support.txt file in each feature directory shows the arch
+support matrix, for all upstream Linux architectures.
+
+The meaning of entries in the tables is:
+
+ | ok | # feature supported by the architecture
+ |TODO| # feature not yet supported by the architecture
+ | .. | # feature cannot be supported by the hardware
