After commit ae7095a7c4 (nfsd4: helper function for getting mounted_on
ino) we ignore the return value from get_parent_attributes().
Also, the following FATTR4_WORD2_LAYOUT_BLKSIZE uses stat.blksize, so to
avoid overwriting that, use an independent value for the parent's
attributes.

If using clientid_counter, it seems possible that gen_confirm could

Both commit 0380a3f375 ("svcrdma: Add a separate "max data segs"
macro for svcrdma") and commit 7e5be28827bf ("svcrdma: advertise
the correct max payload") are incorrect. This commit reverts both
changes, restoring the server's maximum payload size to 1MB.
Commit 7e5be28827bf based the server's maximum payload on the
_client's_ RPCRDMA_MAX_DATA_SEGS value. That was wrong.
Commit 0380a3f375 tried to fix this so that the client maximum
payload size could be raised without affecting the server, but
managed to confuse matters more on the server side.
More importantly, limiting the advertised maximum payload size was
meant to be a workaround, not the actual fix. We need to revisit

server's maximum payload size is restored to 1MB.

Currently, preprocess_stateid_op calls nfs4_check_olstateid which
verifies that the open stateid corresponds to the current filehandle in the
call by calling nfs4_check_fh.
If the stateid is a NFS4_DELEG_STID however, then no such check is done.
This could cause incorrect enforcement of permissions, because the
nfsd_permission() call in nfs4_check_file uses current the current
filehandle, but any subsequent IO operation will use the file descriptor
in the stateid.
Move the call to nfs4_check_fh into nfs4_check_file instead so that it
can be done for all stateid types.

Kernel coding conventions frown upon having large nontrivial
functions in header files, and the preference these days is to
allow the compiler to make inlining decisions if possible.
As these functions are re-homed into a .c file, be sure that
comparisons with fields in struct rpcrdma_msg are with be32
constants.
This is a refactoring change; no behavior change is intended.

The Linux NFS server returns garbage in the data payload of inline
NFS/RDMA READ replies. These are READs of under 1000 bytes or so
where the client has not provided either a reply chunk or a write
list.
The NFS server delivers the data payload for an NFS READ reply to
the transport in an xdr_buf page list. If the NFS client did not
provide a reply chunk or a write list, send_reply() is supposed to
set up a separate sge for the page containing the READ data, and
another sge for XDR padding if needed, then post all of the sges via
a single SEND Work Request.
The problem is send_reply() does not advance through the xdr_buf
when setting up scatter/gather entries for SEND WR. It always calls
dma_map_xdr with xdr_off set to zero. When there's more than one
sge, dma_map_xdr() sets up the SEND sge's so they all point to the
xdr_buf's head.
The current Linux NFS/RDMA client always provides a reply chunk or
a write list when performing an NFS READ over RDMA. Therefore, it
does not exercise this particular case. The Linux server has never
had to use more than one extra sge for building RPC/RDMA replies
with a Linux client.
However, an NFS/RDMA client _is_ allowed to send small NFS READs
without setting up a write list or reply chunk. The NFS READ reply
fits entirely within the inline reply buffer in this case. This is
perhaps a more efficient way of performing NFS READs that the Linux
NFS/RDMA client may some day adopt.

When removing underlying RDMA device, the rmmod will hang forever if there
are any outstanding NFS/RDMA client mounts. The outstanding NFS/RDMA counts
could also prevent the server from shutting down. Further debugging shows
that the existing connections are not teared down and resource are not
released when receiving RDMA_CM_EVENT_DEVICE_REMOVAL event. It seems the
original code missing svc_xprt_put() in RDMA_CM_EVENT_REMOVAL event handler
thus svc_xprt_free is never invoked to release the existing connection
resources.
The patch has been passed removing, adding device back and forth without
stopping NFS/RDMA service. This will also allow a device to be unplugged
and swapped out without shutting down NFS service.

On an absent filesystem (one served by another server), we need to be
able to handle requests for certain attributest (like fs_locations, so
the client can find out which server does have the filesystem), but
others we can't.
We forgot to take that into account when adding another attribute

Things are looking quite decent at this stage but the recent work on
the FPU support took its toll:
- fix an incorrect overly restrictive ifdef
- select O32 64-bit FP support for O32 binary compatibility
- remove workarounds for Sibyte SB1250 Pass1 parts. There are rare
fixing the workarounds is not worth the effort.
- patch up an outdated and now incorrect comment"
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: fpu.h: Allow 64-bit FPU on a 64-bit MIPS R6 CPU
MIPS: SB1: Remove support for Pass 1 parts.
MIPS: Require O32 FP64 support for MIPS64 with O32 compat
MIPS: asm-offset.c: Patch up various comments refering to the old filename.

Pull ARM SoC fixes from Olof Johansson:
"By far most of the fixes here are updates to DTS files to deal with
some mostly minor bugs.
There's also a fix to deal with non-PM kernel configs on i.MX, a
regression fix for ethernet on PXA platforms and a dependency fix for
OMAP"
