77528e2aed RDMA/mlx5: Reorder calls to pcie_relaxed_ordering_enabled() 
The mkc is the key for the mkey cache, hence, created in each attempt to
get a cache mkey, while pcie_relaxed_ordering_enabled() is called during
the setting of the mkc, but used only for cases where
IB_ACCESS_RELAXED_ORDERING is set.

pcie_relaxed_ordering_enabled() is an expensive call (26 us). Reorder the
code so the driver will call it only when it is needed.

9ee2516c43 RDMA/mlx5: Store ndescs instead of the translation table size 
Currently, ent->xlt stores the translation table size. This data should
not be stored in the cache entry but be written directly to the mailbox.
Store ndescs instead, and deduce the translation table size from it
according to the access mode.

56561ac6b2 RDMA/mlx5: Merge similar flows of allocating MR from the cache 
When allocating a MR from the cache, the driver calls to get_cache_mr(),

of mlx5_mr_cache_alloc(), so use it instead.

a099b08599 RDMA/rxe: Revert changes from irqsave to bh locks 
A previous patch replaced all irqsave locks in rxe with bh locks.  This
ran into problems because rdmacm has a bad habit of calling rdma verbs
APIs while disabling irqs. This is not allowed during spin_unlock_bh()
causing programs that use rdmacm to fail.  This patch reverts the changes
to locks that had this problem or got dragged into the same mess. After
this patch blktests/check -q srp now runs correctly.

drivers/infiniband/hw/hfi1/affinity.c code calls cpumask_weight() to check
if any bit of a given cpumask is set. We can do it more efficiently with
cpumask_empty() because cpumask_empty() stops traversing the cpumask as
soon as it finds first set bit, while cpumask_weight() counts all bits
unconditionally.

c1289d5d85 RDMA/rtrs-clt: Do stop and failover outside reconnect work. 
We can't do instant reconnect, not to DDoS server, but we should stop and
failover earlier, so there is less service interruption.

To avoid deadlock, as error_recovery is called from different callback
like rdma event or hb error handler, add a new err recovery_work.

ac491992f3 RDMA/pvrdma: Remove useless DMA-32 fallback configuration 
As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL.

So, if it fails, the 32 bits case will also fail for the same reason.

Simplify code and remove some dead code accordingly.

40c843218f Merge tag 'perf-tools-for-v5.17-2022-01-22' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux 
Pull more perf tools updates from Arnaldo Carvalho de Melo:

 - Fix printing 'phys_addr' in 'perf script'.

 - Fix failure to add events with 'perf probe' in ppc64 due to not
   removing leading dot (ppc64 ABIv1).

 - Fix cpu_map__item() python binding building.

 - Support event alias in form foo-bar-baz, add pmu-events and
   parse-event tests for it.

 - No need to setup affinities when starting a workload or attaching to
   a pid.

 - Use path__join() to compose a path instead of ad-hoc snprintf()
   equivalent.

 - Override attr->sample_period for non-libpfm4 events.

 - Use libperf cpumap APIs instead of accessing the internal state
   directly.

 - Sync x86 arch prctl headers and files changed by the new
   set_mempolicy_home_node syscall with the kernel sources.

 - Remove duplicate include in cpumap.h.

 - Remove redundant err variable.
