Roger Pau Monné 288b2385b8 xen/privcmd: fix integer truncation in IOCTL_PRIVCMD_MMAPBATCH ... The size field in the XENMEM_add_to_physmap_range is an uint16_t, and the privcmd driver was doing an implicit truncation of an int into an uint16_t when filling the hypercall parameters. Fix this by adding a loop and making sure privcmd splits ioctl request into 2^16 chunks when issuing the hypercalls.
