This series has a few small enhancements for the existing standalone floating point stress tests and then builds on those with a kselftest integrated program which gives those a very quick spin from within kselftest, as well as having an option to set a custom timeout to allow for use with longer soak testing. This makes it much easier to get thorough testing of the floating point state management logic, rather than requiring custom setup for coverage of the various vector lengths in the system as is needed at present. It might be nice in future to extend this to attach to some or all of the test programs with ptrace and read/write their registers as another means of potentially triggering race conditions or corruption but that's definitely another step. v2: - Rebase onto v6.0-rc3. - Announce the results of enumeration before we start everything.
