[PATCH v7 07/27] arm64/sve: Check SVE virtualisability

2019-03-29 Thread Dave Martin
Due to the way the effective SVE vector length is controlled and trapped at different exception levels, certain mismatches in the sets of vector lengths supported by different physical CPUs in the system may prevent straightforward virtualisation of SVE at parity with the host. This patch analyses
