The current ECAM kernel implementation uses ioremap() to map the ECAM
configuration space memory region; this is not safe in that on some
architectures the ioremap interface provides mappings that allow posted
write transactions. This, as highlighted in the PCIe specifications (4.0 -
Rev0.3, "Ordering Considerations for the Enhanced Configuration Address
Mechanism"), can create ordering issues for software because posted writes
transactions on the CPU host bus are non posted in the PCI express fabric.

Update the ioremap() interface to use pci_remap_cfgspace() whose mapping
attributes guarantee that non-posted writes transactions are issued for
memory writes within the ECAM memory mapped address region.

The introduction of the pci_remap_cfgspace() interface allows PCI host
controller drivers to map PCI config space through a dedicated kernel
interface. Current PCI host controller drivers use the devm_ioremap_*()
devres interfaces to map PCI configuration space regions so in order to
update them to the new pci_remap_cfgspace() mapping interface a new set of
devres interfaces should be implemented so that PCI host controller drivers
can make use of them.

Introduce two new functions in the PCI kernel layer and Devres
documentation:

- devm_pci_remap_cfgspace()
- devm_pci_remap_cfg_resource()

so that PCI host controller drivers can make use of them to map PCI
configuration space regions.

The offset parameter in the devres devm_ioremap_*() functions kerneldoc

resource address.

Since it is actually misleading, fix the devres devm_ioremap_* offset

description (ie Resource address).

The PCI bus specification (rev 3.0, 3.2.5 "Transaction Ordering and
Posting") defines rules for PCI configuration space transactions ordering
and posting, that state that configuration writes have to be non-posted
transactions.

Current ioremap interface on ARM provides mapping functions that provide
"bufferable" writes transactions (ie ioremap uses MT_DEVICE memory type)
aka posted writes, so PCI host controller drivers have no arch interface to
remap PCI configuration space with memory attributes that comply with the
PCI specifications for configuration space.

Implement an ARM specific pci_remap_cfgspace() interface that allows to map
PCI config memory regions with MT_UNCACHED memory type (ie strongly ordered
- non-posted writes), providing a remap function that complies with PCI
specifications for config space transactions.

The PCI bus specification (rev 3.0, 3.2.5 "Transaction Ordering and
Posting") defines rules for PCI configuration space transactions ordering
and posting, that state that configuration writes are non-posted
transactions.

This rule is reinforced by the ARM v8 architecture reference manual (issue
A.k, Early Write Acknowledgment) that explicitly recommends that No Early
Write Acknowledgment attribute should be used to map PCI configuration
(write) transactions.

Current ioremap interface on ARM64 implements mapping functions where the
Early Write Acknowledgment hint is enabled, so they cannot be used to map
PCI configuration space in a PCI specs compliant way.

Implement an ARM64 specific pci_remap_cfgspace() interface that allows to
map PCI config region with nGnRnE attributes, providing a remap function
that complies with PCI specifications and the ARMv8 architecture reference
manual recommendations.

The PCI specifications (Rev 3.0, 3.2.5 "Transaction Ordering and Posting")
mandate non-posted configuration transactions. As further highlighted in
the PCIe specifications (4.0 - Rev0.3, "Ordering Considerations for the
Enhanced Configuration Access Mechanism"), through ECAM and ECAM-derivative
configuration mechanism, the memory mapped transactions from the host CPU
into Configuration Requests on the PCI express fabric may create ordering
problems for software because writes to memory address are typically posted
transactions (unless the architecture can enforce through virtual address
mapping non-posted write transactions behaviour) but writes to
Configuration Space are not posted on the PCI express fabric.

Current DT and ACPI host bridge controllers map PCI configuration space
(ECAM and ECAM-derivative) into the virtual address space through ioremap()
calls, that are non-cacheable device accesses on most architectures, but
may provide "bufferable" or "posted" write semantics in architecture like
eg ARM/ARM64 that allow ioremap'ed regions writes to be buffered in the bus
connecting the host CPU to the PCI fabric; this behaviour, as underlined in
the PCIe specifications, may trigger transactions ordering rules and must
be prevented.

Introduce a new generic and explicit API to create a memory mapping for
ECAM and ECAM-derivative config space area that defaults to
ioremap_nocache() (which should provide a sane default behaviour) but still
allowing architectures on which ioremap_nocache() results in posted write
transactions to override the function call with an arch specific
implementation that complies with the PCI specifications for configuration
transactions.

pci_remap_iospace() is marked as a weak symbol even though no architecture
is currently overriding it; given that its implementation internals have
already code paths that are arch specific (ie PCI_IOBASE and
ioremap_page_range() attributes) there is no need to leave the weak symbol
in the kernel since the same functionality can be achieved by customizing
per-arch the corresponding functionality.

  CIFS: use DFS pathnames in SMB2+ Create requests
  CIFS: set signing flag in SMB2+ TreeConnect if needed
  CIFS: let ses->ipc_tid hold smb2 TreeIds
  CIFS: add use_ipc flag to SMB2_ioctl()
  CIFS: add build_path_from_dentry_optional_prefix()
  CIFS: move DFS response parsing out of SMB1 code
  CIFS: Fix possible use after free in demultiplex thread

Build of HTML docs failing due to conversion of deviceiobook.tmpl in
8a8a602f and regulator.tmpl in 028f2533 to RST without removing from
DOCBOOKS in Makefile, resulting (in the case of deviceiobook) the
following error:

make[1]: *** No rule to make target 'Documentation/DocBook/deviceiobook.xml', needed by 'Documentation/DocBook/deviceiobook.aux.xml'.  Stop.
Makefile:1452: recipe for target 'htmldocs' failed
make: *** [htmldocs] Error 2

Update DOCBOOKS to reflect available books.
