Make a note in dmesg when we overwrite legacy IDE BAR info. We previously
logged something like this:
pci 0000:00:1f.1: reg 0x10: [io 0x0000-0x0007]
and then silently overwrote the resource. There's an example in the
bugzilla below. This doesn't fix the bugzilla; it just makes what's going
on more obvious.
No functional change; merely adds some dev_info() calls.

The pci_bus_alloc_resource() "type_mask" parameter is used to compare with
the "flags" member of a struct resource, so it should be the same type,
namely "unsigned long".
No functional change because all current IORESOURCE_* flags fit in 32 bits.

When allocating space from a bus resource, i.e., from apertures leading to
this bus, make sure the entire resource type matches. The previous code
assumed the IORESOURCE_TYPE_BITS field was a bitmask with only a single bit
set, but this is not true. IORESOURCE_TYPE_BITS is really an enumeration,
and we have to check all the bits.
See 72dcb1197228 ("resources: Add register address resource type").
No functional change. If we used this path for allocating IRQs, DMA
channels, or bus numbers, this would fix a bug because those types are
indistinguishable when masked by IORESOURCE_IO | IORESOURCE_MEM. But we
don't, so this shouldn't make any difference.

We don't set the type (I/O, memory, etc.) of resources added by
__request_region(), which leads to confusing messages like this:
address space collision: [io 0x1000-0x107f] conflicts with ACPI CPU throttle [??? 0x00001010-0x00001015 flags 0x80000000]
Set the type of a new resource added by __request_region() (used by
request_region() and request_mem_region()) to the type of its parent. This
makes the resource tree internally consistent and fixes messages like the
above, where the ACPI CPU throttle resource really is an I/O port region,
but request_region() didn't fill in the type, so %pR didn't know how to
print it.

Paul reported that after f75b99d5a77d ("PCI: Enforce bus address limits in
resource allocation") on a 32-bit kernel (CONFIG_PHYS_ADDR_T_64BIT not
set), intel-gtt complained "can't ioremap flush page - no chipset
flushing". In addition, other PCI resource allocations, e.g., for bridge
windows, failed.
This happens because we incorrectly skip bus resources of
[mem 0x00000000-0xffffffff] because we think they are of size zero.
When resource_size_t is 32 bits wide, resource_size() on
[mem 0x00000000-0xffffffff] returns 0 because (r->end - r->start + 1)
overflows.
Therefore, we can't use "resource_size() == 0" to decide that allocation
from this resource will fail. allocate_resource() should fail anyway if it
can't satisfy the address constraints, so we should just depend on that.
A [mem 0x00000000-0xffffffff] bus resource is obviously not really valid,
but we do fall back to it as a default when we don't have information about
host bridge apertures.

The generic pci_enable_resources() does essentially the same thing as the
code in the s390 version of pcibios_enable_device().
There are differences, but I don't think any of them are a problem. The
generic code:
- Checks everything up to PCI_NUM_RESOURCES, not PCI_BAR_COUNT (6), so
we'll now check the ROM resource, IOV resources, and bridge windows.
- Checks for res->flags & IORESOURCE_UNSET. The s390 code never sets
IORESOURCE_UNSET, so this isn't a problem.
- Checks res->parent. The s390 pcibios_add_device() calls
pci_claim_resource() on all BARs (except ROM, IOV, and bridge windows)
so this isn't a problem either.

We don't need anything arch-specific in pcibios_enable_device(), so drop
the arch implementation and use the default generic one.
Note: pci_enable_resources() checks that r->parent is non-NULL, which
basically checks that pci_claim_resource() or request_resource() has been
called for each BAR. I don't see where that happens for tile, but this
patch doesn't change that behavior, so if it worked before, it should still
work.

Don't enable memory or I/O decoding if we haven't assigned or claimed the
BAR's resource.
If we enable decoding for a BAR that hasn't been assigned an address, we'll
likely cause bus conflicts. This declines to enable decoding for resources
with IORESOURCE_UNSET.
Note that drivers can use pci_enable_device_io() or pci_enable_device_mem()
if they only care about specific types of BARs. In that case, we don't
bother checking whether the corresponding resources are assigned or
claimed.

Currently, clustering support for scsi_debug is disabled. This is
because there are for_each_sg() loops which assume that each sg list
element is consisted with a single page. But enabling clustering
support, each sg list element for scsi commands can be consisted with
multiple pages.
This replaces these for_each_sg() loops with sg mapping iterator which
is capable of handling each sg list element is consisted with multiple
pages.

When resp_xdwriteread() can't allocate temporary buffer, it returns -1.
But the return value is used as scsi status code and -1 is not

what target_core_mod does for xdwriteread when running out of memory.
