kselftest/arm64: syscall-abi fix and enhancements

[PATCH 0/4] kselftest/arm64: syscall-abi fix and enhancements

Posted by Mark Brown 2 years, 8 months ago

The first patch here is a fix which should ideally be sent as such,
currently the program will hang on architecturally valid systems which
implement SME but not 128 bit vector lengths.  The remaining patches
are general enhancements, including coverage for the SME ABI on SME only
systems.
