* [S390] Program check in diag 210 under 31 bitMichael Holzheu2007-07-10
| | | | | | | | | | If a virtual address is passed to the diag210 function under 31 bit, we get a programming exception, since diag 210 only works with physical addresses. To fix this, the content of the diag210 data structure is copied to a local structure and the physical address of that structure is passed to diagnose 210.

* [S390] Bogomips calculation for 64 bit.Martin Schwidefsky2007-07-10
| | | | | | | | | | The bogomips calculation triggered via reading from /proc/cpuinfo can return incorrect values if the qrnnd assembly is called with a pointer in %r2 with any of the upper 32 bits set. Fix this by using 64 bit division / remainder operation provided by gcc instead of calling the assembly. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add rudimentary check for the case that the page table overflows due to merging of s/g elements by the IOMMU. This would have lead to overwriting of arbitrary memory. After this change I expect that an offending command will be unsuccessfully retried until the scsi_device is taken offline by SCSI core.

Log the effective maximum speed of newly created nodes in dmesg. Also, read the config ROM (except bus info block) at the maximum speed rather than S100. This isn't a real optimization though because we still only use quadlet read requests for the entire ROM. The patch also adds support for S1600 and S3200, although such hardware does not exist yet.

| * ieee1394: remove old isochronous ABIStefan Richter2007-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}" from Adrian Bunk, November 20 2006. This patch also removes the underlying facilities in ohci1394 and disables them in pcilynx. That is, hpsb_host_driver.devctl() and hpsb_host_driver.transmit_packet() are no longer used for iso reception and transmission. Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso interface has never been implemented in pcilynx, pcilynx is now no longer useful for isochronous applications. raw1394 will still handle the request types but will complete the requests with errors that indicate API version conflicts.

This allows for parallelism between several host adapter cards. Properly serialize the driver hooks .update(), .suspend(), .resume(), and .remove() by means of device->sem.

Although all structures are more or less same, raw1394_iso_packets got pointer inside, and raw1394_cycle_timer got unwanted padding in the middle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * write(fd, buf, 52) from 32bit app was returning 56. Most of callers did not care, but some (arm registration) did, and anyway it looks bad if request for writing 52 bytes returns 56. And returning sizeof anything in 'int' is not good as well. So all functions now return '0' instead of sizeof(struct raw1394_request) on success, and write() itself provides correct return value (it just returns value it was asked to write on success as raw1394 does not do any partial writes at all). * Related to this was problem that write() could have returned 0 when kernel state would become corrupted and moved to different state than opened/initialized/connected. Now it returns -EBADFD which seemed appropriate.

Those devices have eaten quite an amount of our quirks space, which isn't particularly necessary - the quirks are not needed after the report descriptor is parsed, and they just consume bits. Therefore this patch separates the quirks for report descriptor fixup, and moves their handling into separate code. The quirks are then forgotten as soon as the report descriptor has been parsed. Module parameter 'rdesc_quirks' is introduced to be able to modify these quirks in runtime in a similar way to 'quirks' parameter for ordinary HID quirks. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
