*	s390/pci: use virtual memory for iommu bitmap	Sebastian Ott	2013-08-30
\| \| \| \| \| \| \| \| \| \|	The bitmap used to mark dma mappings can be quite large on systems with huge amounts of memory. Use virtual memory for this bitmap.

\| \| \| \| \| \|	Rename s390pci_xyz to zpci_xxz and set_irq_ctrl to zpci_set_irq_ctrl. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
*	s390/pci: use to_pci_dev	Sebastian Ott	2013-06-26
\| \| \| \| \| \| \| \| \|	Use the to_pci_dev macro to fetch a pci_dev from a struct device pointer. Reviewed-by: Gerald Schaefer <gerald.schaefer@de.ibm.com> Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
*	s390/pci: return correct dma address for offset > PAGE_SIZE	Gerald Schaefer	2013-04-23
\| \| \| \| \| \| \| \| \| \| \|	For offset > PAGE_SIZE, s390_dma_map_pages() will issue a warning and return a wrong dma address. This patch removes the warning and fixes the dma return address calculation. Signed-off-by: Gerald Schaefer <gerald.schaefer@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
*	s390/pci: rename instruction wrappers	Sebastian Ott	2013-04-17
\| \| \| \| \| \| \| \| \|	Use distinct (and hopefully sane) names for the pci instruction wrappers. Reviewed-by: Gerald Schaefer <gerald.schaefer@de.ibm.com> Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
