Sebastian Ott	add09d61fe	s390/pci: cleanup clp page allocation ... Use the __get_free_pages wrapper in clp_alloc_block. Also change the allocation to use one page only. This page is used as CLP response block e.g. to list available pci functions. Using one page we can list > 250 pci functions at once and we have code to loop around this CLP command (if not all functions fit into to the CLP block) already in place.

Jan Glauber	a755a45dd9	s390/pci: CLP interface ... CLP instructions are used to query the firmware about detected PCI functions, the attributes of those functions and to enable or disable a PCI function. The CLP interface is the equivalent to a PCI bus scan. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>	2012-11-30 15:40:47 +01:00
