IDA adds overhead to store IDs bitmap with maximal value of IDA
can be upto 2099202 (IDA_MAX = 0x80000000U / IDA_BITMAP_BITS - 1).
However, there is no need to add such enormous number of devices
and it is enough for now to limit it to be 8192.

The API surrounding refcount_t should be used in place of atomic_t
when variables are being used as reference counters. This API can
prevent issues such as counter overflows and use-after-free
conditions. Within the dm zoned target stack, the atomic_t API is
used for bioctx->ref and cw->refcount. Change these to use
refcount_t, avoiding the issues mentioned.

iov sysfs tree is created under ib device at

And,
ibdev->ports_parent->parent = &ibdev->dev.
Therefore, refer to device's kobject directly instead of
indirect access to it.
Additionally, iov entries are created under device kobject and deleted
before device is removed. There is no need to hold additional reference
to device kobject in provider driver.

The ucma users supply timeout in u32 format, it means that any number
with most significant bit set will be converted to negative value
by various rdma_*, cma_* and sa_query functions, which treat timeout
as int.
In the lowest level, the timeout is converted back to be unsigned long.

hns3 does one maping, but do multiple unmapping when tx is done,
which may cause unmapping problem.

the non-first bd is zero. If desc_cb.length is zero, we do not
unmap the buffer.

Align the use of local PTT to propagate through the qed_mcp* API's.
Global ptt should not be used.
Register access should be done through layers. Register address is
mapped into a PTT, PF translation table. Several interface functions
require a PTT to direct read/write into register. There is a pool of
PTT maintained, and several PTT are used simultaneously to access
device registers in different flows. Same PTT should not be used in
flows that can run concurrently.
To avoid running out of PTT resources, too many PTT should not be
acquired without releasing them. Every PF has a global PTT, which is
used throughout the life of PF, in most important flows for register
access. Generic functions acquire the PTT locally and release after
the use. This patch aligns the use of Global PTT and Local PTT
accordingly.

hdr.cmd can be indirectly controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/infiniband/core/ucma.c:1686 ucma_write() warn: potential
spectre issue 'ucma_cmd_table' [r] (local cap)
Fix this by sanitizing hdr.cmd before using it to index
ucm_cmd_table.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].
