The following patch-set fixes regressions caused by:
the commit "PCI: update bridge resources to get more big ranges when allocating space (again)" http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=da7822e5ad71ec9b745b412639f1e5e0ba795a20
patch 1/5: fix calculation of additional resource size for hotplug bridges patch 2/5: ability to resize assigned pci-resource patch 3/5: make SRIOV BARs resources optional patch 4/5: make cardbus bridge resources optional patch 5/5: code and terminology cleanup
The regression was caused on some platforms with limited i/o and memory resources, the optional resources were allocated ahead of required resources, thus starving the latter. The patchset ensures that all the required resources are satisfied before any optional resources are satisfied.
