* libata: increase 128 KB / cmd limit for ATAPI tape drivesTony Battersby2007-11-03
| | | | | | | | | | | | | | | | | | | | | | | Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are limited in the amount of data that they can transfer by the max_sectors value. The max_sectors value is currently calculated according to the command set for disk drives, which doesn't apply to tape drives. The default max_sectors value of 256 limits ATAPI tape drive commands to 128 KB. This patch against 2.6.24-rc1 increases the max_sectors value for tape drives to 65535, which permits tape drive commands to transfer just under 32 MB. Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V SATA tape drive. Note that some of the chipset drivers also set their own max_sectors value, which may override the value set in libata-core. I don't have any of these chipsets to test, so I didn't go messing with them. Also, ATAPI devices other than tape drives may benefit from similar changes, but I have only tape drives and disk drives to test.

* sata_promise: fix endianess bug in ASIC PRD bug workaroundMikael Pettersson2007-11-03
| | | | | | | | | | | | | | | | | The original workaround for the Promise ASIC PRD bug contained an endianess bug which I failed to detect: the adjustment of the last PRD entry's length field applied host arithmetic to little-endian data, which is incorrect on big-endian machines. We have the length available in host-endian format, so do the adjustment on host-endian data and then convert and store it in the PRD entry's little-endian data field. Thanks to an anonymous reviewer for detecting this bug. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* Use i8253.c lock for PC speaker on MIPS, too.Ralf Baechle2007-11-02
| | | | | | | | | | The Jazz machines have to use the PIT timer for dyntick and highresolution kernels. This may break because currently just like i386 used to do MIPS uses two separate spinlocks in the actual PIT code and the PC speaker code. So switch to do it the same that x86 currently does PIT locking. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * Input: inport, logibm - use KERN_INFO when reporting missing mouseHelge Deller2007-11-01
| | | | | | | | | | | | | | | | | | | | | | | | Many mouse drivers are often compiled (e.g. in Linux distributions) into the kernel at the same time just to make sure that at least one driver will suceed in find it's mouse device. Nevertheless, only the inport and logitech busmouse mouse drivers report with KERN_ERR log level if the mouse wasn't found. They should use KERN_INFO instead, because it's not an error if the mouse isn't attached at all. Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
