[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v9 02/27] Revert "HYPERCALL_version_op. New hypercall mirroring XENVER_ but sane."
This reverts commit 2716d875379d538c1dfccad78a99ca7db2e09f90.
As it was decided that the existing XENVER hypercall - while having
grown organically over the years can still be expanded.
