The `set_no_disk_inquiry_request` function now uses the correct min

Enables support of different map-on-demand values per NI. This is
required to support OPA coexistence with MLX5 cards. MLX5 does not
support FMR, which is enabled via map-on-demand. However OPA's
performance is greatly enahanced when FMR is enabled. In order
to enable coexistence of both of these two types of cards we
need to be able to set different map-on-demand values for both NIs.
This patch also lays the ground work for other per NI tunables to
be added in future patches.

For a normal FID, we can know on which target the related object
is allocated via querying FLDB; but it is not true for an IDIF.
To locate the OST via the given IDIF, when the IDIF is generated,
we pack the OST index in it. Then for any given FID, in spite of
t is a normal FID or not, we has the method to know which target
it belongs to. That is useful for LFSCK.
For old IDIF, the OST index is not part of the IDIF, means that
ifferent OSTs may have the same IDIFs, that may cause the IFID
in LMA does not match the read FID. Under such case, we need to
make some compatible check to avoid to trigger unexpected.
tgt_validate_obdo() converts the ostid contained in the RPC body
to fid and changes the "struct ost_id" union, then the users can
access ost_id::oi_fid directly without call ostid_to_fid() again.
It also contains some other fixing and cleanup.

When a guest is initializing, KVM provides facility bits that can be
successfully used by the guest. It's done by applying
kvm_s390_fac_list_mask mask on host facility bits stored by the STFLE
instruction. Facility bits can be one of two kinds: it's either a
hypervisor managed bit or non-hypervisor managed.
The hardware provides information which bits need special handling.
Let's automatically passthrough to guests new facility bits, that
don't require hypervisor support.

We only have one cpuid for all VCPUs, so let's directly use the one in the
cpu model. Also always store it directly as u64, no need for struct cpuid.

If we don't have SIGP SENSE RUNNING STATUS enabled for the guest, let's
not enable interpretation so we can correctly report an invalid order.

Only enable PFMF interpretation if the necessary facility (EDAT1) is
available, otherwise the pfmf handler in priv.c will inject an exception

The right part of the following or expression is only evaluated if
td is nonzero.
!td || (td && td.status == USB_TD_INPROGRESS)
So no need to check td again.

The firmware of R-Car USB 3.0 host controller will control the reset.
So, if the xhci driver doesn't do firmware downloading (e.g. kernel
configuration is CONFIG_USB_XHCI_PLATFORM=y and CONFIG_USB_XHCI_RCAR
is not set), the reset of USB 3.0 host controller doesn't work
correctly. Then, the host controller will cause long wait in
xhci_reset() because the CMD_RESET bit of op_regs->command is not
cleared for 10 seconds.
So, this patch modifies the Kconfig to enable both CONFIG_USB_XHCI_PLATFORM
and CONFIG_USB_XHCI_RCAR.
Fixes: 4ac8918f3a7 (usb: host: xhci-plat: add support for the R-Car H2 and M2 xHCI controllers)
