[Qemu-ppc] [PATCH] powerpc pci: fixed packing of ranges[]

Subject: [Qemu-ppc] [PATCH] powerpc pci: fixed packing of ranges[]
Date: Wed, 18 Jul 2012 18:22:51 +1000

By default mingw-gcc is trying to pack structures the way to
preserve binary compatibility with MS Visual C what leads to
incorrect and unexpected padding in the PCI bus ranges property of
the sPAPR PHB.

The patch replaces __attribute__((packed)) with more strict QEMU_PACKED
which actually is __attribute__((gcc_struct, packed)) on Windows.
