Rashmica Gupta 5f337e3e5b selftests/powerpc: Add test to check if VSRs are corrupted ... When a transaction is aborted, VSR values should rollback to the checkpointed values before the transaction began. VSRs used elsewhere in the kernel during a transaction, or while the transaction is suspended should not affect the checkpointed values. Prior to the bug fix in commit d31626f70b ("powerpc: Don't corrupt transactional state when using FP/VMX in kernel") when VMX was requested by the kernel the .vr_state (which held the checkpointed state of VSRs before the transaction) was overwritten with the current state from outside the transation. Thus if the transaction did not complete, the VSR values would be "rolled back" to potentially incorrect values.
