* [S390] s390: rename CPU_IDLE to S390_CPU_IDLEHeiko Carstens2007-07-10
| | | | | | | | | | | | | sched-cfs-v2.6.22-git-v18.patch introduces CPU_IDLE in sched.h. This conflict with the already existing define in include/asm-s390/processor.h Just rename the s390 defines, since they will go away as soon as we support CONFIG_NO_HZ instead of our own CONFIG_NO_IDLE_HZ.

* [S390] zcrypt: fix request timeout handlingRalph Wuerthner2007-07-10
| | | | | | | | | | Under very high load zcrypt requests may timeout while waiting on the request queue. Modify zcrypt that timeouts are based on crypto adapter responses. A timeout occurs only if a crypto adapter does not respond within a given time frame to sumitted requests.

| | | | | | | | | After the in-kernel system call has been remove the system call path can be optimized. The problem state bit of the old psw is always set between system_call and sysc_do_svc.

* [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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

This patch translates relative ABS_VOLUME events into appropriate number of series of VOLUME_UP or VOLUME_DOWN events respectively, so that userspace sees the correct values in the end. kernel.org bugzilla 5233 Reported-by: Jochen Eisinger <jochen@penguin-breeder.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
