This series imports a series of tests for FPSIMD and SVE originally written by Dave Martin to the tree. Since these extensions have some overlap in terms of register usage and must sometimes be tested together they're dropped into a single directory. I've adapted some of the tests to run within the kselftest framework but there are also some stress tests here that are intended to be run as soak tests so aren't suitable for running by default and are mostly just integrated with the build system. There doesn't seem to be a more suitable home for those stress tests and they are very useful for work on these areas of the code so it seems useful to have them somewhere in tree.
v2: Rebased onto v5.9-rc1

Will,
Patches look good to me from selftests perspective. My acked by for these patches to go through arm64.
Acked-by: Shuah Khan skhan@linuxfoundation.org
If you would like me to take these through kselftest tree, give me your Acks. I can queue these up for 5.10-rc1
thanks, -- Shuah
