*	[S390] replace diag10() with diag10_range() function	Michael Holzheu	2011-05-10	1	-21/+0
\| \| \| \| \| \| \| \| \| \| \| \| \|	Currently the diag10() function can only release one page. For exploiters that have to call diag10 on a contiguous memory region this is suboptimal. This patch replaces the diag10() function with diag10_range() that is able to release multiple pages. In addition to that the new function now allows to release memory with addresses higher than 2047 MiB. This was due to a restriction of the diagnose implementation under z/VM prior to release 5.2.

*	[S390] vmur: fix diag14 exceptions with addresses > 2GB.	Michael Holzheu	2007-08-22	1	-0/+102
	There are several s390 diagnose calls, which must be executed below the 2GB memory boundary. In order to enforce this, those diagnoses must be compiled into the kernel. Currently diag 14 can be called within the vmur kernel module from addresses above 2GB. This leads to specification exceptions. This patch moves diag10, diag14 and diag210 into the new diag.c file.
