[Xen-devel] [PATCH v2] Enhancements to hvmloader for Xen 4.8

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Hey!

These two patches came about as I was doing PCI passthrough with
rather large BAR regions and finding a lot of ballooning - which
was unnecessary as we only have 1744MB of MMIO space under 4GB and
all of the ballooning in and out would not help squeeze in a 2GB BAR
or higher in there.

Please review at your convience.

Konrad Rzeszutek Wilk (2):
      hvmloader: Use MB(x) and GB(x) macros
      hvmloader, pci: Don't try to relocate memory if 64-bit BAR is bigger than 
~2GB
