The limited number of link-encryption (IDE) streams that a given set of host bridges supports is a platform specific detail. Provide pci_ide_init_nr_streams() as a generic facility for either platform TSM drivers, or PCI core native IDE, to report the number available streams. After invoking pci_ide_init_nr_streams() an "available_secure_streams" attribute appears in PCI host bridge sysfs to convey that count. Introduce a device-type, @pci_host_bridge_type, now that both a release method and sysfs attribute groups are being specified for all 'struct pci_host_bridge' instances.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
