In bnxt_re_register_ib(), strscpy() is called with the length of the
source string rather than the size of the destination buffer.
This is fine as long as the destination buffer is larger than the source
string, but we should still use the destination buffer size instead to
call strscpy() as intended. And since 'node_desc' has a fixed size, we
can safely omit the size argument and let strscpy() infer it using
sizeof().

When using KSM (Key Scatter-gather Memory) access mode, the HW requires
the IOVA to be aligned to the selected page size.
Without this alignment, the HW may not function correctly.
Currently, mlx5_umem_mkc_find_best_pgsz() does not filter out page sizes
that would result in misaligned IOVAs for KSM mode. This can lead to
selecting page sizes that are incompatible with the given IOVA.
Fix this by filtering the page size bitmap when in KSM mode, keeping
only page sizes to which the IOVA is aligned to.

The mlx5 driver currently derives max_qp_wr directly from the
log_max_qp_sz HCA capability:
props->max_qp_wr = 1 << MLX5_CAP_GEN(mdev, log_max_qp_sz);
However, this value represents the number of WQEs in units of Basic
Blocks (see MLX5_SEND_WQE_BB), not actual number of WQEs. Since the size
of a WQE can vary depending on transport type and features (e.g., atomic
operations, UMR, LSO), the actual number of WQEs can be significantly
smaller than the WQEBB count suggests.
This patch introduces a conservative estimation of the worst-case WQE size
— considering largest segments possible with 1 SGE and no inline data or
special features. It uses this to derive a more accurate max_qp_wr value.

Add new UCMA command and the corresponding CMA implementation. Userspace
can send this command to request service resolution based on service
name or ID.
On a successful resolution, one or multiple service records are
returned, the first one will be used as destination address by default.
Two new CM events are added and returned to caller accordingly:
- RDMA_CM_EVENT_ADDRINFO_RESOLVED: Resolve succeeded;
- RDMA_CM_EVENT_ADDRINFO_ERROR: Resolve failed.
Internally two new CM states are added:
- RDMA_CM_ADDRINFO_QUERY: CM is in the process of IB service
resolution;
- RDMA_CM_ADDRINFO_RESOLVED: CM has finished the resolve process.
With these new states, beside existing state transfer processes, 2 new
processes are supported:
1. The default address is used:
RDMA_CM_ADDR_BOUND ->
RDMA_CM_ADDRINFO_QUERY ->
RDMA_CM_ADDRINFO_RESOLVED ->
RDMA_CM_ROUTE_QUERY
2. To use a different address:
RDMA_CM_ADDR_BOUND ->
RDMA_CM_ADDRINFO_QUERY->
RDMA_CM_ADDRINFO_RESOLVED ->
RDMA_CM_ADDR_QUERY ->
RDMA_CM_ADDR_RESOLVED ->
RDMA_CM_ROUTE_QUERY
In the 2nd case, resolve_addrinfo returns multiple records, a user
could call rdma_resolve_addr() with the one that is not the first.

futex: Move futex cleanup to __mmdrop()
Probe and display L3 Cache topology
Add ability to average an added counter
(useful for pre-integrated "counters", such as Watts)
Break the limit of 64 built-in counters.

may be readable by all, but
/sys/devices/system/cpu/intel_uncore_frequency/package_X_die_Y/current_freq_khz
may be readable only by root.
Non-root turbostat users see complaints in this scenario.
Fail probe of the interface if we can't read current_freq_khz.

Together with the RAPL MSRs, there are more MSRs gone on DMR, including
PLR (Perf Limit Reasons), and IRTL (Package cstate Interrupt Response
Time Limit) MSRs. The configurable TDP info should also be retrieved
from TPMI based Intel Speed Select Technology feature.
Remove the access of these MSRs for DMR. Improve the DMR platform
feature table to make it more readable at the same time.
