2012-11-15Drivers: hv: Add Hyper-V balloon driverK. Y. Srinivasan
Add the basic balloon driver. Windows hosts dynamically manage the guest memory allocation via a combination memory hot add and ballooning. Memory hot add is used to grow the guest memory upto the maximum memory that can be allocatted to the guest. Ballooning is used to both shrink as well as expand up to the max memory. Supporting hot add needs additional support from the host. We will support hot add when this support is available. For now, by setting the VM startup memory to the VM max memory, we can use ballooning alone to dynamically manage memory allocation amongst competing guests on a given host. Signed-off-by: K. Y.

2012-09-04hv: vmbus_drv: detect hyperv through x86_hyperJason Wang
There are two reasons we need to use x86_hyper instead of query_hypervisor_presence(): - Not only hyperv but also other hypervisors such as kvm would set X86_FEATURE_HYTPERVISOR, so query_hypervisor_presence() will return true even in kvm. This may cause extra delay of 5 seconds before failing the probing in kvm guest. - The hypervisor has been detected in init_hypervisor(), so no need to do the work again.

The utf8s_to_utf16s conversion routine needs to be improved. Unlike its utf16s_to_utf8s sibling, it doesn't accept arguments specifying the maximum length of the output buffer or the endianness of its 16-bit output. This patch (as1501) adds the two missing arguments, and adjusts the only two places in the kernel where the function is called. A follow-on patch will add a third caller that does utilize the new capabilities. The two conversion routines are still annoyingly inconsistent in the way they handle invalid byte combinations.
