RXE_POOL_ALIGN is only used in rxe_pool.c so move RXE_POOL_ALIGN to
rxe_pool.c from rxe_pool.h. RXE_POOL_CACHE_FLAGS is never used so it is
deleted from rxe_pool.h

In rxe_pool.c currently there are many cases where it is necessary to
compute the offset from a pool element struct to the object containing it
in a type independent way where the offset is different for each type. By
saving a pointer to the object when they are created extra work can be
saved.

In rxe_pool.c copy remaining pool setup parameters from rxe_pool_info into
rxe_pool. This saves looking up rxe_pool_info in the performance path.

Currently three different names are used to describe rxe pool elements.
They are referred to as entries, elems or pelems. This patch chooses one
'elem' and changes the other ones.

Most of the locks in the rxe driver are _irqsave/restore locks but in fact
there are no interrupt threads that run rxe code or share data with
rxe. There are softirq threads and data sharing so the appropriate lock
type is _bh. This patch replaces all irqsave type locks with bh type
locks.

The 'cmdq->cmdq_bitmap' bitmap is 'rcfw->cmdq_depth' bits long. The size
stored in 'cmdq->bmap_size' is the size of the bitmap in bytes.
Remove this erroneous 'bmap_size' and use 'rcfw->cmdq_depth' directly in
'bnxt_qplib_disable_rcfw_channel()'. Otherwise some error messages may be
missing.
Other uses of 'cmdq_bitmap' already take into account 'rcfw->cmdq_depth'
directly.

When optional counter support was added the allocation of the memory
holding the counter descriptors was not cleared properly. This caused
WARN_ON()s in the IB/sysfs code to be hit.
This is because the uninitialized memory made some of the counters wrongly
look like optional counters. Use kzalloc.
While here change the sizeof() calls to use the pointer rather than the
name of the type.

This change is needed for mlx5, because in case of QP creation failure, it
will go to the path of QP destroy which relies on proper CQ pointers.

some churn in obsolete drivers and a sweep through all drivers to call
scsi_done() directly instead of scsi->done() which removes a pointer
indirection from the hot path and a move to register core sysfs files
earlier, which means they're available to KOBJ_ADD processing, which

Here is the big set of char and misc and other tiny driver subsystem
updates for 5.16-rc1.
Loads of things in here, all of which have been in linux-next for a
while with no reported problems (except for one called out below.)
Included are:
- habanana labs driver updates, including dma_buf usage,
reviewed and acked by the dma_buf maintainers
- iio driver update (going through this tree not staging as they
really do not belong going through that tree anymore)
- counter driver updates
- hwmon driver updates that the counter drivers needed, acked by
the hwmon maintainer
- xillybus driver updates
- binder driver updates
- extcon driver updates
- dma_buf module namespaces added (will cause a build error in
arm64 for allmodconfig, but that change is on its way through
the drm tree)
- lkdtm driver updates
- pvpanic driver updates
- phy driver updates
- virt acrn and nitr_enclaves driver updates

If the driver returns a new MR during rereg it has to fill it with the
IOVA from the proper source. If IB_MR_REREG_TRANS is set then the IOVA is
cmd.hca_va, otherwise the IOVA comes from the old MR. mlx5 for example has
two calls inside rereg_mr:
return create_real_mr(new_pd, umem, mr->ibmr.iova,
new_access_flags);
and
return create_real_mr(new_pd, new_umem, iova, new_access_flags);
Unconditionally overwriting the iova in the newly allocated MR will
corrupt the iova if the first path is used.
Remove the redundant initializations from ib_uverbs_rereg_mr().

In the function irdma_post_recv, the function irdma_copy_sg_list is
not needed since the struct irdma_sge and ib_sge have the similar
member variables. The struct irdma_sge can be replaced with the
struct ib_sge totally.
This can increase the rx performance of irdma.

Add a new implementation for mmap by using the new mmap entry API. This

The upper limit of MAX_LP_MSG_LEN on HIP08 is 64K, and the upper limit on
HIP09 is 16K. Regardless of whether it is HIP08 or HIP09, only 16K will be
used. In order to ensure compatibility, it is unified to 16K.
Setting MAX_LP_MSG_LEN to 16K will not cause performance loss on HIP08.

We set the init CQ status to ARMED before. As a result, an unexpected CEQE
would be reported. Therefore, the init CQ status should be set to no_armed
rather than REG_NXT_CEQE.

'index.table' is a bitmap. So use 'bitmap_zalloc()' to simplify code,
improve the semantic and avoid some open-coded arithmetic in allocator
arguments.
Using 'bitmap_zalloc()' also allows the removal of a now useless
'bitmap_zero()'.
Also change the corresponding 'kfree()' into 'bitmap_free()' to keep
consistency.

Introduce ib_umem_dmabuf_get_pinned() which allows the driver to get a
dmabuf umem which is pinned and does not require move_notify callback
implementation.
The returned umem is pinned and DMA mapped like standard cpu umems, and is
released through ib_umem_release() (incl. unpinning and unmapping).
