2013-02-14	s390/pci: cleanup clp page allocation	Sebastian Ott	1	-1/+1
	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.

2012-11-30	s390/pci: CLP interface	Jan Glauber	1	-0/+28
	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>
