*	[S390] qdio: convert global statistics to per-device stats	Jan Glauber	2010-01-04
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Revamp the qdio performance statistics and move them from procfs to debugfs using the seq_file interface. Since the statistics are not intended for the general user the removal of /proc/qdio_perf should not surprise anyone. The per device statistics are disabled by default, writing 1 to /<debugfs mountpoint>/qdio/<device bus ID>/statistics enables the statistics for the given device.

*	[S390] cio: consistent infrastructure for internal I/O requests	Peter Oberparleiter	2009-12-07
\| \| \| \| \| \| \| \|	Reduce code duplication by introducing a central infrastructure to perform an internal I/O operation on a CCW device. Signed-off-by: Peter Oberparleiter <peter.oberparleiter@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
*	[S390] cio: move scsw helper functions to header file	Heiko Carstens	2009-09-11
\| \| \| \| \| \| \| \| \| \|	All scsw helper functions are very short and usage of them shouldn't result in function calls. Therefore we move them to a separate header file. Also saves a lot of EXPORT_SYMBOLs. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
*	[S390] split/move machine check handler code	Heiko Carstens	2009-03-26

*	[S390] qdio: new qdio driver.	Jan Glauber	2008-07-17
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	List of major changes: - split qdio driver into several files - seperation of thin interrupt code - improved handling for multiple thin interrupt devices - inbound and outbound processing now always runs in tasklet context - significant less tasklet schedules per interrupt needed - merged qebsm with non-qebsm handling - cleanup qdio interface and added kerneldoc - coding style Reviewed-by: Cornelia Huck <cornelia.huck@de.ibm.com> Reviewed-by: Utz Bacher <utz.bacher@de.ibm.com> Reviewed-by: Ursula Braun <braunu@de.ibm.com> Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
*	[S390] cio: Add chsc subchannel driver.	Cornelia Huck	2008-07-14
\| \| \| \| \| \| \| \| \| \| \| \| \|	This patch adds a driver for subchannels of type chsc. A device /dev/chsc is created which may be used to issue ioctls to: - obtain information about the machine's I/O configuration - dynamically change the machine's I/O configuration via asynchronous chsc commands Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

*	[S390] cio: replace subchannel evaluation queue with bitmap	Peter Oberparleiter	2007-04-27
\| \| \| \| \| \| \| \| \| \| \| \|	Use a bitmap for indicating which subchannels require evaluation instead of allocating memory for each evaluation request. This approach reduces memory consumption during recovery in case of massive evaluation request occurrence and removes the need for memory allocation failure handling.

*	Linux-2.6.12-rc2v2.6.12-rc2	Linus Torvalds	2005-04-16
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
