2008-04-08ub: remove BUG() after __blk_end_request and fix the condition causing itPete Zaitcev
When __blk_end_request returns nonzero, it means that the request was not completely processed and some BIOs are still attached. Since we have dequeued it by that time, it means leaking requests and hanging processes, which is why BUG() was in there. In ub this happens if a packet request ends normally, but with residue (e.g. when scsi_id issues INQUIRY). The fix is to make sure that arguments passed to __blk_end_request are correct: the full request length and not just transferred length. The transferred length is indicated to applications by adjusting rq->data_len with old, unchanged code outside of this patch.

These 32-bit CPUs have 36-bit physical address and PCI I/O and memory spaces are mapped beyond 4 GB; arch/ppc/ code has a fixup in ioremap() that creates an illusion of the PCI I/O and memory resources being mapped below 4 GB, while arch/powerpc/ code got rid of this fixup with PPC 44x having instead CONFIG_RESOURCES_64BIT=y -- this causes the resources to be truncated to 32-bit 'unsigned long' type in this driver, and so non-existant memory being ioremap'ed and then accessed...

The 'disable_cb' callback is designed as an optimization to tell the host we don't need callbacks now. As it is not reliable, the debug check is overzealous: it can happen on two CPUs at the same time. Document this. Even if it were reliable, the virtio_net driver doesn't disable callbacks on transmit so the START_USE/END_USE debugging reentrance protection can be easily tripped even on UP.

2008-04-06scsi: fix sense_slab/bio swapping livelockHugh Dickins
Since 2.6.25-rc7, I've been seeing an occasional livelock on one x86_64 machine, copying kernel trees to tmpfs, paging out to swap. Signature: 6000 pages under writeback but never getting written; most tasks of interest trying to reclaim, but each get_swap_bio waiting for a bio in mempool_alloc's io_schedule_timeout(5*HZ); every five seconds an atomic page allocation failure report from kblockd failing to allocate a sense_buffer in __scsi_get_command. __scsi_get_command has a (one item) free_list to protect against this, but rc1's [SCSI] use dynamically allocated sense buffer de25deb18016f66dcdede165d07654559bb332bc upset that slightly. When it fails to allocate from the separate sense_slab, instead of giving up, it must fall back to the command free_list, which is sure to have a sense_buffer attached. Either my earlier -rc testing missed this, or there's some recent contributory factor. One very significant factor is SLUB, which merges slab caches when it can, and on 64-bit happens to merge both bio cache and sense_slab cache into kmalloc's 128-byte cache: so that under this swapping load, bios above are liable to gobble up all the slots needed for scsi_cmnd sense_buffers below. That's disturbing behaviour, and I tried a few things to fix it. Adding a no-op constructor to the sense_slab inhibits SLUB from merging it, and stops all the allocation failures I was seeing; but it's rather a hack, and perhaps in different configurations we have other caches on the swapout path which are ill-merged. Another alternative is to revert the separate sense_slab, using cache-line-aligned sense_buffer allocated beyond scsi_cmnd from the one kmem_cache; but that might waste more memory, and is only a way of diverting around the known problem. While I don't like seeing the allocation failures, and hate the idea of all those bios piled up above a scsi host working one by one, it does seem to emerge fairly soon with the livelock fix. So lacking better ideas, stick with that one clear fix for now.

2008-04-04ipmi: change device node ordering to reflect probe orderCarol Hebert
In 2.6.14 a patch was merged which switching the order of the ipmi device naming from in-order-of-discovery over to reverse-order-of-discovery. So on systems with multiple BMC interfaces, the ipmi device names are being created in reverse order relative to how they are discovered on the system (e.g. on an IBM x3950 multinode server with N nodes, the device name for the BMC in the first node is /dev/ipmiN-1 and the device name for the BMC in the last node is /dev/ipmi0, etc.). The problem is caused by the list handling routines chosen in dmi_scan.c. Using list_add() causes the multiple ipmi devices to be added to the device list using a stack-paradigm and so the ipmi driver subsequently pulls them off during initialization in LIFO order. This patch changes the dmi_save_ipmi_device() list handling paradigm to a queue, thereby allowing the ipmi driver to build the ipmi device names in the order in which they are found on the system.

fix memory corruption and crash due to mis-sized grant table. A PV OS has two grant table data structures: the grant table itself and a free list. The free list is composed of an array of pages, which grow dynamically as the guest OS requires more grants. While the grant table contains 8-byte entries, the free list contains 4-byte entries. So we have half as many pages in the free list than in the grant table. There was a bug in the free list allocation code. The free list was indexed as if it was the same size as the grant table. But it's only half as large. So memory got corrupted, and I was seeing crashes in the slab allocator later on.

2008-04-03[TG3]: Add PHY workaround for 5784Matt Carlson
The 5784 B step and newer chips require the PHY DSPs to be fine-tuned based on one-time programmable values stored in the chip. This is essential to achieve optimal PHY operations especially when using long cables. We also need to properly handle the 10Mbit RX bit in the CPMU_CTRL register during PHY reset. Update version to 3.89. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-04-03[POWERPC] Fix MPC5200 (not B!) device tree so FEC ethernet worksRené Bürgel
This gets the FEC ethernet driver working again on the lite5200 platform. The FEC driver is also compatible with the MPC5200, not only with the MPC5200B, so this adds a suitable entry to the driver's match list. Furthermore this adds the settings for the PHY in the dts file for the Lite5200. Note, that this is not exactly the same as in the Lite5200B, because the PHY is located at f0003000:01 for the 5200, and at :00 for the 5200B. This was tested on a Lite5200 and a Lite5200B, both booted a kernel via tftp and mounted the root via nfs successfully.
