Pull vfs inode time accessor updates from Christian Brauner:
 "This finishes the conversion of all inode time fields to accessor
  functions as discussed on list. Changing timestamps manually as we
  used to do before is error prone. Using accessors function makes this
  robust.

  It does not contain the switch of the time fields to discrete 64 bit
  integers to replace struct timespec and free up space in struct inode.
  But after this, the switch can be trivially made and the patch should
  only affect the vfs if we decide to do it"

cb7ab7854b IB/qib: Replace deprecated strncpy
`strncpy` is deprecated for use on NUL-terminated destination strings [1]
and as such we should prefer more robust and less ambiguous string
interfaces.

We know `txselect_list` is expected to be NUL-terminated based on its
use in `param_get_string()`:
| int param_get_string(char *buffer, const struct kernel_param *kp)
| {
| 	const struct kparam_string *kps = kp->str;
| 	return scnprintf(buffer, PAGE_SIZE, "%s\n", kps->string);
| }

Note that `txselect_list` is assigned to `kp_txselect`'s string field:
| static struct kparam_string kp_txselect = {
| 	.string = txselect_list,
| 	.maxlen = MAX_ATTEN_LEN
| };

Wherein it is then assigned the set and get methods:
| module_param_call(txselect, setup_txselect, param_get_string,
| 		  &kp_txselect, S_IWUSR | S_IRUGO);

Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

 - Usual driver cleanups in qedr, siw, erdma, hfi1, mlx4/5, irdma, mthca,
   hns, and bnxt_re
 
 - siw now works over tunnel and other netdevs with a MAC address by
   removing assumptions about a MAC/GID from the connection manager
 
 - "Doorbell Pacing" for bnxt_re - this is a best effort scheme to allow
   userspace to slow down the doorbell rings if the HW gets full

 - rxe bug fixes in queue draining and srq resizing
 
 - Support more ethernet speed options in the core layer

 - Multi-stage MTT support for erdma to allow much bigger MR registrations

Now that the driver core allows for struct class to be in read-only

placing them into read-only memory, instead of having to be dynamically

This clears the way to removing the vmas parameter from GUP altogether.

556eb8b791 Driver core changes for 6.4-rc1
Here is the large set of driver core changes for 6.4-rc1.
 
 Once again, a busy development cycle, with lots of changes happening in
 the driver core in the quest to be able to move "struct bus" and "struct
 class" into read-only memory, a task now complete with these changes.
 
 This will make the future rust interactions with the driver core more
 "provably correct" as well as providing more obvious lifetime rules for
 all busses and classes in the kernel.
 
 The changes required for this did touch many individual classes and
 busses as many callbacks were changed to take const * parameters
 instead.  All of these changes have been submitted to the various
 subsystem maintainers, giving them plenty of time to review, and most of
 them actually did so.
 
 Other than those changes, included in here are a small set of other
 things:
   - kobject logging improvements
   - cacheinfo improvements and updates
   - obligatory fw_devlink updates and fixes
   - documentation updates
   - device property cleanups and const * changes
   - firwmare loader dependency fixes.
 
 All of these have been in linux-next for a while with no reported
 problems.

697d5cf073 IB/qib: Drop redundant pci_enable_pcie_error_reporting()
pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

6ea0c2de31 RDMA/qib: Remove deprecated kmap() call
kmap() has been deprecated in favor of the kmap_local_page() call.
kmap_local_page() is thread local.

In the sdma coalesce case the page allocated is potentially free'ed in a
different context through qib_sdma_get_complete() ->
qib_user_sdma_make_progress().  The use of kmap_local_page() is
inappropriate in this call path.  However, the page is allocated using
GFP_KERNEL and will never be from highmem.

Remove the use of kmap calls and use page_address() in this case.

1aaba11da9 driver core: class: remove module * from class_create()
The module pointer in class_create() never actually did anything, and it
shouldn't have been requred to be set as a parameter even if it did
something.  So just remove it and fix up all callers of the function in
the kernel tree at the same time.

20ea778323 RDMA/hw/qib/qib_user_pages: remove FOLL_FORCE usage
FOLL_FORCE is really only for ptrace access. As we unpin the pinned pages
using unpin_user_pages_dirty_lock(true), the assumption is that all these
pages are writable.

FOLL_FORCE in this case seems to be a legacy leftover. Let's just remove
it.

32f57cb1b2 IB/qib: Fix duplicate sysfs directory name
The qib driver load has been failing with the following message:

  sysfs: cannot create duplicate filename '/devices/pci0000:80/0000:80:02.0/0000:81:00.0/infiniband/qib0/ports/1/linkcontrol'

The patch below has two "linkcontrol" names causing the duplication.

Fix by using the correct "diag_counters" name on the second instance.

7b6397d7e5 drivers/infiniband: replace open-coded string copy with get_task_comm
We'd better use the helper get_task_comm() rather than the open-coded
strlcpy() to get task comm.  As the comment above the hard-coded 16, we
can replace it with TASK_COMM_LEN.
