The target needs to return the lesser of the client's Inbound RDMA
Read Queue Depth (IRD), provided in the connection parameters, and
the local device's Outbound RDMA Read Queue Depth (ORD). The latter
limit is max_qp_init_rd_atom, not max_qp_rd_atom.

The svcrdma_ord value caps the ORD value for iWARP transports, which
do not exchange ORD/IRD values at connection time. Since no other
Linux kernel RDMA-enabled storage target sees fit to provide this
cap, I'm removing it here too.

initiator_depth is a u8, so ensure the computed ORD value does not

In a traditional NFS deployment using auth_unix, the clients are trusted
to correctly report the credentials of their logged-in users.  The
server assumes that only root on client machines is allowed to send
requests from low-numbered ports, so it can use the originating port
number to distinguish "real" NFS clients from NFS clients run by
ordinary users, to prevent ordinary users from spoofing credentials.

The originating port number on a gss-authenticated request is less
important.  The authentication ties the request to a user, and we take
it as proof that that user authorized the request.  The low port number
check no longer adds much.

So, don't enforce low port numbers in the auth_gss case.

The interface for flushing the sunrpc auth cache was poorly
designed and has caused problems a number of times.

The design is that you write a timestamp, and all entries
created before that time are discarded.
The most obvious problem is that this is not what people
actually want.  They want to just flush the whole cache.
The 1-second granularity can be a problem, as can the use
of wall-clock time.

A current problem is that code will write the current time to
this file - expecting it to clear everything - and if the
seconds number ticks over before this timestamp is checked,
the test "then >= now" fails, and a full flush isn't forced.

So lets just drop the subtleties and always flush the whole
cache.  The worst this could do is impose an extra cost
refilling it, but that would require someone to be using
non-standard tools.

We still report an error if the string written is not a number,
but we cause any valid number to flush the whole cache.

Commit fd8aa909 ("xen: optimize xenbus driver for multiple concurrent
xenstore accesses") optimized xenbus concurrent accesses but in doing so
broke UABI of /dev/xen/xenbus. Through /dev/xen/xenbus applications are in
charge of xenbus message exchange with the correct header and body. Now,
after the mentioned commit the replies received by application will no
longer have the header req_id echoed back as it was on request (see
specification below for reference), because that particular field is being
overwritten by kernel.

struct xsd_sockmsg
{
  uint32_t type;  /* XS_??? */
  uint32_t req_id;/* Request identifier, echoed in daemon's response.  */
  uint32_t tx_id; /* Transaction id (0 if not related to a transaction). */
  uint32_t len;   /* Length of data following this. */

  /* Generally followed by nul-terminated string(s). */
};

Before there was only one request at a time so req_id could simply be
forwarded back and forth. To allow simultaneous requests we need a
different req_id for each message thus kernel keeps a monotonic increasing
counter for this field and is written on every request irrespective of
userspace value.

Forwarding again the req_id on userspace requests is not a solution because
we would open the possibility of userspace-generated req_id colliding with
kernel ones. So this patch instead takes another route which is to
artificially keep user req_id while keeping the xenbus logic as is. We do
that by saving the original req_id before xs_send(), use the private kernel
counter as req_id and then once reply comes and was validated, we restore
back the original req_id.

  ia64: fix build failure with CONFIG_SWIOTLB

In many cases, page tables can be accessed concurrently by either another
CPU (due to things like fast gup) or by the hardware page table walker
itself, which may set access/dirty bits. In such cases, it is important
to use READ_ONCE/WRITE_ONCE when accessing page table entries so that
entries cannot be torn, merged or subject to apparent loss of coherence
due to compiler transformations.

Whilst there are some scenarios where this cannot happen (e.g. pinned
kernel mappings for the linear region), the overhead of using READ_ONCE
/WRITE_ONCE everywhere is minimal and makes the code an awful lot easier
to reason about. This patch consistently uses these macros in the arch
code, as well as explicitly namespacing pointers to page table entries
from the entries themselves by using adopting a 'p' suffix for the former
(as is sometimes used elsewhere in the kernel source).
