Change 4787572d0580 made if_alloc_domain() never fail, then also do the

No functional change intended.

ntb_hw_plx: Workaround read-only scratchpad registers2024-02-05T20:37:15ZAlexander Motinmav@FreeBSD.org2024-01-27T21:51:46Zurn:sha1:825b7c222a6b47ebf5d8974d02e3a7d9b59f5a0d
On several systems we've noticed that when NTB link goes down, the
Physical Layer User Test Pattern registers we use as additional
scratchpad registers (that is explicitly allowed by the chip specs)
become read-only for about 100us. I see no explanation for this in
the chip specs, neither why it was not seen before, may be a race.
Since we do need these registers, workaround it by repeating writes
until we succeed or 1ms timeout expire.

ntb: Use uintmax_t casts and %j to print physical addresses.2022-09-28T20:56:31ZJohn Baldwinjhb@FreeBSD.org2022-09-28T20:56:31Zurn:sha1:124e46735e07037afafbf0caa097faafb09c7329
This fixes -Wint-to-pointer-cast errors with GCC when compiling on
i386 where physical addresses are not the same size as pointers.

In NTB gen3 driver, it was supposed to disable NTB bar access by
default, but due to incorrect register access method, the bar disable
logic does not work as expected. Those registers should be modified
through NTB bar0 rather than PCI configuration space.
Besides, we'd better to protect ourselves from a bad buddy node so
ingress disable logic should be implemented together.

The only thing around NTB using Giant lock is NewBus, and these callouts
have nothing to do with it.
