 "New AMD PCI ID for NTB, and a number of bug fixes for ntb_hw_switchtec
  for Linux v5.17"

* tag 'ntb-5.17' of git://github.com/jonmason/ntb:
  ntb_hw_switchtec: Fix a minor issue in config_req_id_table()
  ntb_hw_switchtec: Remove code for disabling ID protection
  ntb_hw_switchtec: Update the way of getting VEP instance ID
  ntb_hw_switchtec: AND with the part_map for a valid tpart_vec
  ntb_hw_switchtec: Fix bug with more than 32 partitions
  ntb_hw_switchtec: Fix pff ioread to read into mmio_part_cfg_all
  ntb_hw_switchtec: fix the spelling of "its"
  NTB/msi: Fix ntbm_msi_request_threaded_irq() kernel-doc comment
  ntb_hw_amd: Add NTB PCI ID for new gen CPU

The req_id_table_size field is 16-bit wide, use ioread16() to read the
value.

ID protection is a firmware setting for NT window access control. With
it enabled, only the posted requests with requester IDs in the requester
ID table will be allowed to access the NT windows. Otherwise all posted
requests are allowed. Normally user will configure it statically via the
Switchtec config file, and it will take effect when the firmware boots
up. The driver can also toggle the ID protection setting dynamically,
which will overwrite the static setting in the Switchtec config file as
a side effect.

Currently, the driver disables the ID protection. However, it's not
necessary to disable the ID protection at the driver level as the driver
has already configured the proper requester IDs in the requester ID
table to allow the corresponding posted requests to hit the NT windows.
Remove the code that disables the ID protection to make the static
setting prevail.

Note: ID protection is not applicable to non-posted requests.

Some firmware versions return 1 in the target partition vector for
undefined partitions. AND with the part_map to give a valid tpart_vec.

Switchtec could support as mush as 48 partitions, but ffs & fls are
for 32 bit argument, in case of partition index larger than 31, the
current code could not parse the peer partition index correctly.
Change to the 64 bit version __ffs64 & fls64 accordingly to fix this
bug.

Array mmio_part_cfg_all holds the partition configuration of all
partitions, with partition number as index. Fix this by reading into
mmio_part_cfg_all for pff.

Use the possessive "its" instead of the contraction "it's" (it is)
in user messages.

in ntbm_msi_request_threaded_irq() kernel-doc comment to remove
some warnings found by running scripts/kernel-doc, which is caused
