I will try to change all the callers to kvmalloc() and kvzalloc(). The kvmalloc() and kvzalloc() are not ready to use in staging-testing branch on staging tree. If the kvmalloc and kvzalloc are available to use, I will replace atomisp_kernel_malloc() and atomisp_kernel_zalloc() with kvmalloc() and kvzalloc(). Thanks.
