[RESEND PATCH v2 2/4] PCI: Do not Use IORESOURCE_STARTALIGN to identify bridge resources

Now we use the IORESOURCE_STARTALIGN to identify bridge resources in __assign_resources_sorted(). That's quite fragile. We can't make sure that the PCI devices' resources will not use IORESOURCE_STARTALIGN any more. In this patch, we try to use a more robust way to identify bridge resources.

[RESEND PATCH v2 0/4] PCI: Add support for enforcing all MMIO BARs not to share PAGE_SIZE

This series aims to add an option for PCI resource allocator to force BARs not to share PAGE_SIZE. This would make sense to VFIO driver. Because current VFIO implementation disallows to mmap sub-page(size < PAGE_SIZE) MMIO BARs which may share the same page with other BARs for security

[RESEND PATCH v2 3/4] PCI: Add a new option for resource_alignment to reassign alignment

When using resource_alignment kernel parameter, the current implement reassigns the alignment by changing resources' size which can potentially break some drivers. For example, the driver uses the size to locate some register whose length is related to the size. This patch adds a new option

[PATCH 4/4] drm/doc: Appease sphinx

Mostly this is unexpected indents. But really it's just a demonstration for my patch, all these issues have been found using the correct source file and line number support I just added. All line numbers have been perfectly accurate. One issue looked a bit fishy in intel_lrc.c, where I don't
