46bdf77768 RDMA: Fix dependencies for rdma_user_mmap_io
The mlx4 driver produces a link error when it is configured
as built-in while CONFIG_INFINIBAND_USER_ACCESS is set to =m:

drivers/infiniband/hw/mlx4/main.o: In function `mlx4_ib_mmap':
main.c:(.text+0x1af4): undefined reference to `rdma_user_mmap_io'

The same function is called from mlx5, which already has a
dependency to ensure we can call it, and from hns, which
appears to suffer from the same problem.

This adds the same dependency that mlx5 uses to the other two.

0425e3e6e0 RDMA/hns: Support flush cqe for hip08 in kernel space
According to IB protocol, there are some cases that work requests must
return the flush error completion status through the completion queue. Due
to hardware limitation, the driver needs to assist the flush process.

This patch adds the support of flush cqe for hip08 in the cases that
needed, such as poll cqe, post send, post recv and aeqe handle.

The patch also considered the compatibility between kernel and user space.

d34ac5cd3a RDMA, core and ULPs: Declare ib_post_send() and ib_post_recv() arguments const
Since neither ib_post_send() nor ib_post_recv() modify the data structure
their second argument points at, declare that argument const. This change
makes it necessary to declare the 'bad_wr' argument const too and also to
modify all ULPs that call ib_post_send(), ib_post_recv() or
ib_post_srq_recv(). This patch does not change any functionality but makes
it possible for the compiler to verify whether the
ib_post_(send|recv|srq_recv) really do not modify the posted work request.

To make this possible, only one cast had to be introduce that casts away
constness, namely in rpcrdma_post_recvs(). The only way I can think of to
avoid that cast is to introduce an additional loop in that function or to
change the data type of bad_wr from struct ib_recv_wr ** into int
(an index that refers to an element in the work request list). However,
both approaches would require even more extensive changes than this
patch.

 2) allow making references to nodes other than device nodes in ACPI.

As a by-product, convert the fwnode interger arguments to u64. The
arguments were 64-bit integers on ACPI but the fwnode arguments were
just 32-bit.

33023fb85a IB/core: add max_send_sge and max_recv_sge attributes
This patch replaces the ib_device_attr.max_sge with max_send_sge and
max_recv_sge. It allows ulps to take advantage of devices that have very
different send and recv sge depths.  For example cxgb4 has a max_recv_sge
of 4, yet a max_send_sge of 16.  Splitting out these attributes allows
much more efficient use of the SQ for cxgb4 with ulps that use the RDMA_RW
API. Consider a large RDMA WRITE that has 16 scattergather entries.
With max_sge of 4, the ulp would send 4 WRITE WRs, but with max_sge of
16, it can be done with 1 WRITE WR.

47ec386662 RDMA: Convert drivers to use sgid_attr instead of sgid_index
The core code now ensures that all driver callbacks that receive an
rdma_ah_attrs will have a sgid_attr's pointer if there is a GRH present.

Drivers can use this pointer instead of calling a query function with
sgid_index. This simplifies the drivers and also avoids races where a
gid_index lookup may return different data if it is changed.

fad953ce0b treewide: Use array_size() in vzalloc()
The vzalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:

        vzalloc(a * b)

with:
        vzalloc(array_size(a, b))

as well as handling cases of:

        vzalloc(a * b * c)

with:

        vzalloc(array3_size(a, b, c))

This does, however, attempt to ignore constant size factors like:

        vzalloc(4 * 1024)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

6396bb2215 treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

// Fix redundant parens around sizeof().

type TYPE;
expression THING, E;

f5e27a203f Merge branch 'k.o/for-rc' into k.o/wip/dl-for-next
Several items of conflict have arisen between the RDMA stack's for-rc
branch and upcoming for-next work:

9fd4350ba8 ("IB/rxe: avoid double kfree_skb") directly conflicts with
2e47350789 ("IB/rxe: optimize the function duplicate_request")

Patches already submitted by Intel for the hfi1 driver will fail to
apply cleanly without this merge

Other people on the mailing list have notified that their upcoming
patches also fail to apply cleanly without this merge

Merge tag 'for-linus-unmerged' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma updates from Jason Gunthorpe:
 "Doug and I are at a conference next week so if another PR is sent I
  expect it to only be bug fixes. Parav noted yesterday that there are
  some fringe case behavior changes in his work that he would like to
  fix, and I see that Intel has a number of rc looking patches for HFI1
  they posted yesterday.

  Parav is again the biggest contributor by patch count with his ongoing
  work to enable container support in the RDMA stack, followed by Leon
  doing syzkaller inspired cleanups, though most of the actual fixing
  went to RC.

  There is one uncomfortable series here fixing the user ABI to actually
  work as intended in 32 bit mode. There are lots of notes in the commit
  messages, but the basic summary is we don't think there is an actual
  32 bit kernel user of drivers/infiniband for several good reasons.

  However we are seeing people want to use a 32 bit user space with 64
  bit kernel, which didn't completely work today. So in fixing it we
  required a 32 bit rxe user to upgrade their userspace. rxe users are
  still already quite rare and we think a 32 bit one is non-existing.

   - Fix RDMA uapi headers to actually compile in userspace and be more
     complete

71591d1280 RDMA/hns: Replace __raw_write*(cpu_to_le*()) with LE write*()
There is no need to repeat the semantics of writel() and similar.
Moreover sparse complains about this:

drivers/infiniband/hw/hns/hns_roce_hw_v1.c:1690:22: expected unsigned long long val
drivers/infiniband/hw/hns/hns_roce_hw_v1.c:1690:22: got restricted __le64 <noident>

Fixing this by replacing __raw_write*(cpu_to_le*()) calls by plain
write*() ones.

Note, write*() accessors are little endian by definition.

8b9b8d143b RDMA/hns: Fix the endian problem for hns
The hip06 and hip08 run on a little endian ARM, it needs to
revise the annotations to indicate that the HW uses little
endian data in the various DMA buffers, and flow the necessary
swaps throughout.

The imm_data use big endian mode. The cpu_to_le32/le32_to_cpu
swaps are no-op for this, which makes the only substantive
change the handling of imm_data which is now mandatory swapped.

This also keep match with the userspace hns driver and resolve
the warning by sparse.
