2009-03-26[S390] Use csum_partial in checksum.hFrank Munzert1-1/+3
The cksm function in system.h is duplicate to csum_partial in checksum.h. Remove cksm and use csum_partial instead. Signed-off-by: Frank Munzert <munzert@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2008-07-17[S390] zfcpdump: Make SCSI disk dump tool recognize storage holesFrank Munzert1-7/+94
The kernel part of zfcpdump establishes a new debugfs file zcore/memmap which exports information on memory layout (start address and length of each memory chunk) to its userspace counterpart.

2007-10-12[S390] zcore: fix inline assembly in memcpy_real()Michael Holzheu1-3/+4
memcpy_real uses the mvcle instruction. This instruction alters all used registers (source, destination and 2 x count). Therefore we have to flag those registers as input/output registers (+d). In addition to that, we have to specify, that we read from memory designated by "src" and write to memory designated by "dest".

2007-04-27[S390] zfcpdump support.Michael Holzheu1-0/+651
s390 machines provide hardware support for creating Linux dumps on SCSI disks. For creating a dump a special purpose dump Linux is used. The first 32 MB of memory are saved by the hardware before the dump Linux is booted. Via an SCLP interface, the saved memory can be accessed from Linux. This patch exports memory and registers of the crashed Linux to userspace via a debugfs file. For more information refer to Documentation/s390/zfcpdump.txt, which is included in this patch.
