| * ethtool: Call ethtool's get/set_settings callbacks with cleaned dataDavid Decotigny2011-04-292-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes sure that when a driver calls the ethtool's get/set_settings() callback of another driver, the data passed to it is clean. This guarantees that speed_hi will be zeroed correctly if the called callback doesn't explicitely set it: we are sure we don't get a corrupted speed from the underlying driver. We also take care of setting the cmd field appropriately (ETHTOOL_GSET/SSET). This applies to dev_ethtool_get_settings(), which now makes sure it sets up that ethtool command parameter correctly before passing it to drivers. This also means that whoever calls dev_ethtool_get_settings() does not have to clean the ethtool command parameter. This function also becomes an exported symbol instead of an inline. All drivers visible to make allyesconfig under x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * | [SCSI] qla2xxx: Refactor call to qla2xxx_read_sfp for thermal temperature.Joe Carnuccio2011-05-171-42/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eliminate duplicate code by refactoring the calls to qla2xxx_read_sfp() in qla2x00_get_thermal_temp(). This keeps the parameter values separate from the mailbox register mechanics. This also allows qla2xxx_read_sfp() to be the sole "spec" for READ SFP semantics.

| * | [SCSI] arcmsr: simplify some double loops in sleeping functionsTomas Henzl2011-05-011-74/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I removed outer loops in ...wait_msgint_ready the sleeptime and retrycount are in fact never changed so I changed them into defines. In arcmsr_flush_hba_cache is a loop removed, which printed the same printk 100 times, one line in log is enough I think. The arcmsr_sleep_for_bus_reset has lost a functionality with the latest patches, The only thing the function does is a long sleep, so it's replaced with a ssleep.

| * | [SCSI] iterate over devices individually for /proc/scsi/scsiJeff Mahoney2011-05-011-6/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems with very large numbers (> 1600 or so) of SCSI devices, cat /proc/scsi/scsi ends up failing with -ENOMEM. This is due to the show routine simply iterating over all of the devices with bus_for_each_dev(), and trying to dump all of them into the buffer at the same time. On my test system (using scsi_debug with 4064 devices), the output ends up being ~ 632k, far more than kmalloc will typically allow. This patch defines its own seq_file opreations to iterate over the scsi devices.The result is that each show() operation only dumps ~ 180 bytes into the buffer at a time so we don't run out of memory. If the "Attached devices" header isn't required, we can dump the sfile->private bit completely. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

| * | [SCSI] ibmvscsi: Improve CRQ reset reliabilityBrian King2011-05-011-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an issue seen where an event occurs which causes the ibmvscsi driver to reset its CRQ. Upon re-registering its CRQ, it receives H_CLOSED, indicating the Virtual I/O Server is not yet ready to receive commands. This resulted in the ibmvscsi driver essentially offlining the adapter and not recovering. The fix is to re-enable our interrupt so that when the Virtual I/O server is ready and sends a CRQ init, we will be able to receive it and resume initialization of the VSCSI adapter.

| * | [SCSI] ipr: increase the dump size for 64 bit adaptersKleber Sacilotto de Souza2011-05-012-21/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the size of the dump generated by the driver is limited in 4MB, which is insufficient to gather much useful data from the new 64 bit adapters. This patch makes the needed changes to increase the dump limit for the 64 bit adapters to 32MB, or even to a bigger value in the future, but keeping the current limitations for the legacy 32 bit adapters.
