The specifications for the Armv8.1-M Mainline can be found in https://developer.arm.com/docs/ddi0553/latest The patch series looks fine to me, apart from two small problems: 1) It introduces some assembler testsuite failures for non-ELF based ARM toolchains: Checking Binutils in: arm-wince-pe ...

Cheers Nick PS. This was from testing with the entire patch series applied. I have not narrowed down the specific patches that introduce the new failures, but I assume that it will be simple for you to do this yourself.
