This driver has lots of functions marked always inline which is actually
counterproductive with modern compilers. Better to move the functions to
the one file they are used (proper scope) and let compiler decide.
For trivial functions leave them as static inline.

virtio_net_hdr_mem member within virtqueue structure stores a
physical address and is defined as void ptr. When 32bit pmd is used
with 64bit kernel this leads to truncation of 64bit physical address
and pkt i/o does not work.

removed the typecasts

Since Linux commit fb51ccbf217 (PCI: Rework config space blocking services),
the functions pci_(un)block_user_cfg_access are replaced by
pci_cfg_access_(un)lock.
The compatibility with older functions was broken since commit 399a3f0db8b0
(igb_uio: fix IRQ mode handling).

This pach reworks how IRQ mode handling is done.
The biggest code change is to use the standard INTX management
code that exists in more recent kernels (and provide backport version).
This also fixes the pci_lock code which was broken, since it was
not protecting against config access, and was doing trylock.
Make this driver behave like other Linux drivers.
Start at MSI-X and degrade to less desireable modes
automatically if the desired type is not available.

Since only one MSI-X entry is ever defined, there is no need to
put it as an array in the driver private data structure. One msix_entry
can just be put on the stack and initialized there.
Also remove the unused backport defines related to MSI-X.
I suspect this code was just inherited from some other project and
never cleaned up.
