Other nits: please make this similar to previous changelogs in
capitalization, sentence structure, etc. If we figure out that this
is safe, and I end up applying it, I can just tweak it myself, but if
you post it again, something like this is what I'm looking for:
PCI: Don't allocate child bus outside parent bus number range
Don't allocate a child bus if the new bus number does not fit in the
parent's bus resource window.
The next patch is missing a subject line:
PCI/MSI: Export MSI and IRQ functions for use by modules
Export the following functions for use by modules:
msi_desc_to_pci_dev()
pci_msi_create_irq_domain()
irq_domain_set_info()
And the following:
x86/PCI: Allow PCI domain-specific DMA ops
I know this seems pedantic, but try to use "x86/PCI" consistently
because I think it's distracting to have the boiler-plate be different
in non-useful ways, e.g.,
510fb6779eed x86/pci: Initial commit for new VMD device driver
510fb6779eed x86/pci: Initial commit for new VMD device driver
b7a48e92f508 x86-pci: allow pci domain specific dma ops
8affb487d4a4 x86/PCI: Don't alloc pcibios-irq when MSI is enabled
991de2e59090 PCI, x86: Implement pcibios_alloc_irq() and pcibios_free_irq()
