clocksource/hyperv_timer.h is included into the VDSO build. It includes asm/mshyperv.h which in turn includes the world and some more. This worked so far by chance, but any subtle change in the include chain results in a build breakage because VDSO builds are building user space libraries. Include asm/hyperv-tlfs.h instead which contains everything what the VDSO build needs except the hv_get_raw_timer() define. Move this define into a separate header file, which contains the prerequisites (msr.h) and is included by clocksource/hyperv_timer.h. Fixup drivers/hv/vmbus_drv.c which relies on the indirect include of asm/mshyperv.h. With that the VDSO build only pulls in the minimum requirements.
