With encrypted memory and confidential computing it became harder to maintain every changes in these hypercall implementations. Intention of this patchset is to introduce arch independent VMware hypercall API layer other subsystems such as device drivers can call to, while hiding architecture specific implementation behind. Second patch introduces the vmware_hypercall low and high bandwidth families of functions, with little enhancements there. Sixth patch adds tdx hypercall support arm64 implementation of vmware_hypercalls is in drivers/gpu/drm/ vmwgfx/vmwgfx_msg_arm64.h and going to be moved to arch/arm64 with a separate patchset with the introduction of VMware Linux guest support for arm64. No functional changes in drivers/input/mouse/vmmouse.c and drivers/ptp/ptp_vmw.c v1->v2 changes (no functional changes): - Improved commit message in patches 2 and 5. - Added Reviewed-by for all patches. - Added Ack from Dmitry Torokhov in patch 4. No fixes regarding reported by Simon Horman gcc error in this patch. x86 maintainers, please consider merging this patch set in your branch.
