Relax DEVX access upon modify commands to be UVERBS_ACCESS_READ.
The kernel doesn't need to protect what firmware protects, or what
causes no damage to anyone but the user.
As firmware needs to protect itself from parallel access to the same
object, don't block parallel modify/query commands on the same object in
the kernel side.
This change will allow user space application to run parallel updates to
different entries in the same bulk object.

- Rework and simplify eventfd_signal() and eventfd_signal_mask()

- Make relatime_need_update() return bool
- Use GFP_KERNEL instead of GFP_USER when allocating superblocks
- Replace deprecated ida_simple_*() calls with their current ida_*()
counterparts

- Fix a false-positive lockdep warning in pipe_write() for watch

Gen P7 adapters needs to share a toggle bits information received
in kernel driver with the user space. User space needs this
info during the request notify call back to arm the CQ.
User space application can get this page using the
UAPI routines. Library will mmap this page and get the
toggle bits to be used in the next ARM Doorbell.
Uses a hash list to map the CQ structure from the CQ ID.
CQ structure is retrieved from the hash list while the
library calls the UAPI routine to get the toggle page
mapping. Currently the full page is mapped per CQ. This
can be optimized to enable multiple CQs from the same
application share the same page and different offsets
in the page.

This patch introduces improvements for matching egress traffic sent by the
local device. When applicable, all egress traffic from the local vport is
now tagged with the provided value. This enhancement is particularly useful
for FDB steering purposes.
The primary focus of this update is facilitating the transmission of
traffic from the hypervisor to a VF. To achieve this, one must initiate an
SQ on the hypervisor and subsequently create a rule in the FDB that matches
on the eswitch manager vport and the SQN of the aforementioned SQ.
Obtaining the SQN can be had from SQ opened, and the eswitch manager vport
match can be substituted with the register c0 value exposed by this patch.

Add basic support for 5760X P7 devices. Add new chip
revisions. The first version support is similar to
the existing P5 adapters. Extend the current support
for P5 adapters to P7 also.

When a reserved QP fails to be created, the memory of the remaining

IB-core and rdma-core restrict the sgid_index specified by users,
which is uint8_t/u8 data type, to only be within the range of 0-255,
so it's meaningless to support excessively large gid_table_len.
On the other hand, ib-core creates as many sysfs gid files as
gid_table_len, most of which are not only useless because of the
reason above, but also greatly increase the traversal time of
the sysfs gid files for applications.
This patch limits the maximum length of gid table to 256.

Now, different devices may have the same interrupt name, which
makes it difficult for users to distinguish between these
interrupts.
Modify the naming style to be consistent with our network devices.
Before:
"hns-aeq-0"
"hns-ceq-0"
...
Now:
"hns-0000:35:00.0-aeq-0"
"hns-0000:35:00.0-ceq-0"

Virtual QP and CQ require a 4K HW page size but the driver passes
PAGE_SIZE to ib_umem_find_best_pgsz() instead.
Fix this by using the appropriate 4k value in the bitmap passed to
ib_umem_find_best_pgsz().

The SQ is shared for between kernel and used by storing the kernel page
pointer and passing that to a kmap_atomic().
This then requires that the alignment is PAGE_SIZE aligned.
Fix by adding an iWarp specific alignment check.

Ever since the eventfd type was introduced back in 2007 in commit
e1ad7468c7 ("signal/timer/event: eventfd core") the eventfd_signal()
function only ever passed 1 as a value for @n. There's no point in
keeping that additional argument.
