nvme: limit I/O queue trackers to Identify MAXCMD
MAXCMD is the maximum number of commands the controller processes at
one time for a particular I/O queue. Allocating more trackers than
that only queues commands inside the controller. Controllers
reporting 0 are unaffected.

nvme: name the Create I/O queue cdw11 fields, use Medium QPRIO
The Create I/O queue commands carried magic 0x1/0x3 cdw11 values, and
the implicit QPRIO of zero classifies every I/O queue Urgent the
moment weighted round robin arbitration is enabled. No functional
change with the round robin default.

bce_vhci: fix duplicate endpoint queue registration, ratelimit failure logging
bce_vhci_endpoint_create() was registering both the IN and OUT
submission queues on every call, regardless of which direction
the endpoint actually needed.
The per-stage firmware registration failures weren't rate-limited,
so a stuck registration will spam the console.

mlx5ib: use the hardware Toeplitz id when creating an RSS TIR
create_rss_raw_qp_tir() wrote MLX5_RX_HASH_FUNC_TOEPLITZ (the

the hardware encoding from mlx5_ifc.h, where 1 is INVERTED_XOR8 and
Toeplitz is MLX5_TIRC_RX_HASH_FN_HASH_TOEPLITZ (2).

linuxkpi: Add `hrtimer_setup()`
`hrtimer_setup()` replaces `hrtimer_init()` in Linux 6.15. The API and
the role are the same, except:
* it takes the `function` callback as argument
* if `function` is NULL, it assigns a default callback
At the same time, we hide `hrtimer_init()` if LINUXKPI_VERSION is
greater than or equal to 61500 because it was dropped in Linux 6.15.

nfsuserd.c: Fix handling where pw_name/gr_name differ from lookup name
When an NSS backend returns a canonical pw_name or gr_name that differs from
the lookup name supplied by the NFSv4 upcall, nfsuserd stores the successful
mapping in the kernel cache under the canonical name instead of the requested
name.
This causes the retry lookup performed by nfsv4_strtouid() or
nfsv4_strtogid() to miss the newly inserted cache entry, resulting in the
default UID/GID being returned although the NSS lookup itself succeeded.

linuxkpi: Fix assertion in `lkpi_vmf_insert_pfn_prot_locked()`
Before this change, the assertion would not catch a page index matching
the end address, even though the end address of a mapping is outside of
that mapping.
While here, add another assertion to catch page indexes outside of the
expected range earlier.
Also, pagefaulting an address outside of the mapping range should return
`VM_FAULT_SIGBUS` instead of panicing.
