Linus Torvalds 3491aa0478 VFIO updates for v6.15-rc1
- Relax IGD support code to match display class device rather than
    specifically requiring a VGA device. (Tomita Moeko)
 
  - Accelerate DMA mapping of device MMIO by iterating at PMD and PUD
    levels to take advantage of huge pfnmap support added in v6.12.
    (Alex Williamson)
 
  - Extend virtio vfio-pci variant driver to include migration support
    for block devices where enabled by the PF. (Yishai Hadas)
 
  - Virtualize INTx PIN register for devices where the platform does
    not route legacy PCI interrupts for the device and the interrupt
    is reported as IRQ_NOTCONNECTED. (Alex Williamson)

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.
