2006-02-23sbp2: update 36byte inquiry workaround (fix compatibility regression)Stefan Richter
Since about Linux 2.6.14, sbp2's inquiry workaround did not work anymore due to changes in the SCSI layer. Update it to become effective again. Testing one of the two known affected bridges has shown that skip_ms_page_8 is required as well. Also, make force_inquiry_hack tunable via /sys/module/sbp2/parameters.

2006-02-23sbp2: variable status FIFO address (fix login timeout)Stefan Richter
Let the ieee1394 core select a suitable 1394 address range for sbp2's status FIFO instead of using a fixed range. Since the core only selects addresses which are guaranteed to be out of the "physical range" as per OHCI 1.1, this patch also fixes an old bug: OHCI controllers which implement a writeable PhysicalUpperBound register included sbp2's status FIFO in the physical range. That way sbp2 was never notified of a succesful login and always failed after timeout. Affected OHCI host adapters include ALi and Fujitsu controllers. As another side effect of this patch, the status FIFO is no longer located in a range for which OHCI chips perform "posted writes". Each status write now requires a response subaction. But since large data transfers involve only few status writes, there is no measurable decrease of I/O throughput. What's more, the status FIFO is now safe from potential host bus errors. Nevertheless, posted writes could be re-enabled by extensions to the ARM features of the 1394 stack.

2006-02-23sbp2: fix another deadlock after disconnectionStefan Richter
If there were commands enqueued but not completed before an SBP-2 unit was unplugged (or an attempt to reconnect failed), knodemgrd or any process which tried to remove the device would sleep uninterruptibly in blk_execute_rq(). Therefore make sure that all commands are completed when sbp2 retreats.

2006-02-20[PATCH] s390: V=V qdio fixesFrank Pavlic
Using FCP devices with V=V support, the input queue stalled when CCQ 97 had been returned in qdio_do_eqbs. When this happen we have to reissue the eqbs instruction. Another bug was when V=V was enabled we checked if hardware has SIGA-sync support. If not we returned with 0 from tiqdio_is_inbound_q_done. Thus qdio lost initiative on FCP devices and input queue stalled. Running devices in V=V there is no SIGA-sync support but nevertheless we have to process tiqdio_is_inbound_q_done either.

2006-02-20[PATCH] Terminate process that fails on a constrained allocationChristoph Lameter
Some allocations are restricted to a limited set of nodes (due to memory policies or cpuset constraints). If the page allocator is not able to find enough memory then that does not mean that overall system memory is low. In particular going postal and more or less randomly shooting at processes is not likely going to help the situation but may just lead to suicide (the whole system coming down). It is better to signal to the process that no memory exists given the constraints that the process (or the configuration of the process) has placed on the allocation behavior. The process may be killed but then the sysadmin or developer can investigate the situation. The solution is similar to what we do when running out of hugepages. This patch adds a check before we kill processes. At that point performance considerations do not matter much so we just scan the zonelist and reconstruct a list of nodes. If the list of nodes does not contain all online nodes then this is a constrained allocation and we should kill the current process.

2006-02-20[PATCH] libata: fix WARN_ON() condition in *_fill_sg()Tejun Heo

This patch fixes the assert()'s to take qc->pad_len into account. Although the condition check seems a bit excessive, as this part of code isn't still stable yet, I think it's worth to keep those.

2006-02-19[IRDA]: irda-usb bug fixesJean Tourrilhes
This patch fixes 2 bugs in the USB-IrDA code. The first one is a buffer overrun in the RX path. We are now using IRDA_SKB_MAX_MTU when initializing the Rx URB. The second one is a potential stack recursion when unplugging the USB dongle. It seems that first we get the Rx URB with a generic error code, and after a while the Rx URB comes again with a "disconnect" error code. Since we are resubmitting the Rx URB immediately after receiving the first error one, we might enter an endless loop. When getting an error Rx URB, the patch defers the Rx URB resubmitting so that it gives us a chance to catch the disconnect one, in case the dongle has juts been unplugged. Tested against 2.6.16-rc2.

2006-02-17[PATCH] ACPI: fix vendor resource length computationBjorn Helgaas
acpi_rs_get_list_length() needs to account for all the vendor-defined data bytes. Failing to include these causes buffers to be sized too small, which causes slab corruption when we later convert AML to resources and run off the end of the buffer. This causes slab corruption on machines that use ACPI vendor-defined resources. All HP ia64 machines do, and I'm told that some NEC machines may as well.
