By default the sve bits are not set. This patch adds a new hypercall, xc_altp2m_set_supress_ve_multi(), to set a range of sve bits. The core function, p2m_set_suppress_ve_multi(), does not break in case of a error and it is doing a best effort for setting the bits in the given range. A check for continuation is made in order to have preemption on large ranges. The gfn of the first error is stored in xen_hvm_altp2m_suppress_ve_multi.first_error_gfn and the error code is stored in xen_hvm_altp2m_suppress_ve_multi.first_error. If no error occurred the values will be 0.
