Michael reported that the x86/hyperv initialization code printed the
following dmesg when running in a VM on Hyper-V:
[ 0.000738] Booting paravirtualized kernel on bare hardware
Let the x86/hyperv initialization code set pv_info.name to "Hyper-V";
with this addition, the dmesg read:
[ 0.000172] Booting paravirtualized kernel on Hyper-V

Changes since v1 ([1]):
- move the setting of pv_info.name to ms_hyperv_init_platform() (Wei Liu)

Thomas, will you be taking this? Would you rather have me deal with the
hyperv bits under arch/x86/?
