This patch implements use of kvmalloc for GFP_KERNEL allocations, which may increase performance if the allocator is able to allocate physical memory, if kvmalloc is available as a public kernel interface (since v4.12). Otherwise it will simply fall back to virtual memory (vmalloc). Also fix vmem_alloc implementation which can lead to slow allocations since the first attempt with kmalloc does not make use of the noretry flag but tells the linux kernel to retry several times before it fails.
