[PATCH v4 7/9] pseries/plpks: add HCALLs for PKWM wrapping key life cycle management

[sashiko-bot at kernel.org]

> The PKWM trusted source uses a single wrapping key per LPAR, created only
> once during trust source initialization. All the wrap and unwrap requests
> are bound to this default wrapping key.
> 
> Implement H_PKS_REVOKE_OBJECT, H_PKS_UNREVOKE_OBJECT, and
> H_PKS_GET_OBJECTLABELS HCALLs to enable support for revoking and unrevoking
> PKWM wrapping keys, and for retrieving wrapping key labels. The label
> retrieval operation (H_PKS_GET_OBJECTLABELS) applies to all wrapping keys
> including the default one, while the life cycle operations
> (H_PKS_REVOKE_OBJECT/H_PKS_UNREVOKE_OBJECT) apply only to user-created
> wrapping keys.
