drm/i915: prepare for fair lru eviction

- Add an alignment parameter for evict_something. It's not really great to
  whack a carefully sized hole into the gtt with the wrong alignment.
  Especially since the fallback path is a full evict.

- With the inactive scan stuff we need to evict more that one object, so
  move the unbind call into the helper function that scans for the object
  to be evicted, too.  And adjust its name.

one outstanding pageflip request.

Furthermore I've changed the busy loop into a ringbuffer wait.
Busy-loops that don't check whether the chip died are simply evil.
And performance should actually improve, because there's usually
a decent amount of rendering queued on the gpu, hopefully rendering
that MI_WAIT into a noop by the time it's executed.

The current code holds dev->struct_mutex while executing this loop,
hence stalling all other gem activity anyway.

nfsd: don't allow setting maxblksize after svc created

It's harmless to set this after the server is created, but also
ineffective, since the value is only used at the time of
svc_create_pooled().  So fail the attempt, in keeping with the pattern
set by write_versions, write_{lease,grace}time and write_recoverydir.

(This could break userspace that tried to write to nfsd/max_block_size
between setting up sockets and starting the server.  However, such code
wouldn't have worked anyway, and I don't know of any examples--rpc.nfsd

Commit 59db4a0c102e0de226a3395dbf25ea51bf845937 "nfsd: move more into
nfsd_startup()" inadvertently moved nfsd_versions after

not explicitly set the list of nfsd versions, this results in
svc-create_pooled() being called with an empty versions array.  The
resulting incomplete initialization leads to a NULL dereference in
svc_process_common() the first time a client accesses the server.

Move nfsd_reset_versions() back before the svc_create_pooled(); this
time, put it closer to the svc_create_pooled() call, to make this
mistake more difficult in the future.

nfsd41: Fix a crash when a callback is retried

If a callback is retried at nfsd4_cb_recall_done() due to
some error, the returned rpc reply crashes here:

@@ -514,6 +514,7 @@ decode_cb_sequence(struct xdr_stream *xdr, struct nfsd4_cb_sequence *res,
  u32 dummy;
  __be32 *p;

 + BUG_ON(!res);
  if (res->cbs_minorversion == 0)
  return 0;

[BUG_ON added for demonstration]

This is because the nfsd4_cb_done_sequence() has NULLed out
the task->tk_msg.rpc_resp pointer.

Also eventually the rpc would use the new slot without making
sure it is free by calling nfsd41_cb_setup_sequence().

This problem was introduced by a 4.1 protocol addition patch:
[0421b5c5] nfsd41: Backchannel: Implement cb_recall over NFSv4.1

Which was overlooking the possibility of an RPC callback retries.
For not-4.1 case redoing the _prepare is harmless.
