* UBI: use vmalloc for large buffersArtem Bityutskiy2007-07-18
| | | | | | | UBI allocates temporary buffers of PEB size, which may be 256KiB. Use vmalloc instead of kmalloc for such big temporary buffers. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: add few more commentsArtem Bityutskiy2007-07-18
| | | | | | | Add few comments above ubi_scan_add_used() to explain why it is so complex. Requested by Satyam Sharma <satyam.sharma@gmail.com>. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: set correct gluebi device sizeArtem Bityutskiy2007-07-18

* UBI: fix error path in create_vtbl()Artem Bityutskiy2007-07-18
| | | | | | | | | | | There were several bugs in volume table creation error path. Thanks to Satyam Sharma <satyam.sharma@gmail.com> and Florin Malita <fmalita@gmail.com> for finding and analysing them: http://lkml.org/lkml/2007/5/3/274 This patch makes ubi_scan_add_to_list() static and renames it to add_to_list(), just because it is not needed outside scan.c anymore.

* slob: Kill off duplicate kzalloc() definition.Paul Mundt2007-07-17
| | | | | | | | | | With the slab zeroing allocations cleanups Christoph stubbed in a generic kzalloc(), which was missed on SLOB.

* Revert drivers/ide/ide.c scsi_cmd_ioctl() usage changesLinus Torvalds2007-07-17
| | | | | | | | | | | | | The old IDE driver is not ready to take generic SCSI commands, even if it uses them for some specific issues (ie the tray open/close ioctls for IDE CD-ROM's). Pointed out by Bartlomiej. I'm sure we'll have it fixed properly soon enough, but for now we should not allow it to cause problems.

| * [S390] qdio: output queue stall on FCP and network devicesFrank Pavlic2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | When running QIOASSIST enabled qdio devices in a z/VM environment the output queue for such devices stall in heavy workload situations. When SQBS and EQBS instructions returns CCQ=96 qdio does not reissue the instruction again with the register settings done by millicode but processed the returned qdio buffer. This is wrong. qdio has to reissue the instruction once again on CCQ=96, as we already do it for CCQ=97.

| * [S390] Fix disassembly of RX_URRD, SI_URD & PC-relative instructions.Christian Borntraeger2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The instructions with format RX_URRD and SI_URD and instructions with a PC relative operand are not disassembled correctly. For RX_URRD and SI_URD instructions find_insn sets opfrag to code[0]. The mask byte of these two formats is 0x00. table->opfrag will never be identical to (opfrag & opmask) and no matching instruction will be found. Set the mask byte to 0xff to actually check byte 0 against the table. For PC relative instructions the (unsigned) offset value needs to be casted to an signed integer so that negative branch offsets are handled correctly.
