Even after the previous fix you can still set CONFIG_ACPI_BOOT indirectly even without CONFIG_ACPI by choosing CONFIG_PCI and CONFIG_PCI_MMCONFIG. That doesn't build very well either. This makes PCI_MMCONFIG depend on ACPI, fixing that hole. [ I guess in theory Kconfig could follow the whole chain of dependencies for things that get selected, but that sounds insanely complicated, so we'll just fix up these things by hand. --Linus ] Signed-off-by: Alexander Nyberg <alexn@telia.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

There is a race in the kernel cpuset code, between the code to handle notify_on_release, and the code to remove a cpuset. The notify_on_release code can end up trying to access a cpuset that has been removed. In the most common case, this causes a NULL pointer dereference from the routine cpuset_path. However all manner of bad things are possible, in theory at least. The existing code decrements the cpuset use count, and if the count goes to zero, processes the notify_on_release request, if appropriate. However, once the count goes to zero, unless we are holding the global cpuset_sem semaphore, there is nothing to stop another task from immediately removing the cpuset entirely, and recycling its memory. The obvious fix would be to always hold the cpuset_sem semaphore while decrementing the use count and dealing with notify_on_release. However we don't want to force a global semaphore into the mainline task exit path, as that might create a scaling problem. The actual fix is almost as easy - since this is only an issue for cpusets using notify_on_release, which the top level big cpusets don't normally need to use, only take the cpuset_sem for cpusets using notify_on_release. This code has been run for hours without a hiccup, while running a cpuset create/destroy stress test that could crash the existing kernel in seconds. This patch applies to the current -linus git kernel.

The original pwc author raised some questions about the reverse engineering of the decompressor algorithms used in the pwc driver. Having done some detailed investigation it appears those concerns that clean room policy was not followed are reasonable. I've also had a friendly discussion with Philips to ask their view on this. This removes the problem items of code which reduces the pwc functionality in the kernel a little but leaves all the framework for setup that will be needed for decompressors in user space (where they eventually belong). This change set is designed to be the minimal risk change set given that 2.6.12 is hopefully close to hand, with a view to merging the much updated pwc code in 2.6.13 series kernels. Someone else can then redo the decompressors properly (clean room) in user space. Note that while its easy to say that it should have been caught earlier, but the violation was really only obvious to someone who had access to both the proprietary source and the 'GPL' source.

We fixed this bug before, but it didn't take. It may have been the case that the problem was first noticed to occur in a CONFIG_REGPARM compile. But it's not regparm functions that need not to make tail calls, it's asmlinkage functions called with a user pt_regs frame on the stack supplying their arguments. prevent_tail_call probably doesn't do anything at all in regparm functions (your argument registers are going to be clobbered, period). It was a braino to conditionalize that definition in the first place. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Here is a fixed up version of the reorder feature of netem. It is the same as the earlier patch plus with the bugfix from Julio merged in. Has expected backwards compatibility behaviour. Go ahead and merge this one, the TCP strangeness I was seeing was due to the reordering bug, and previous version of TSO patch.

Netem works better if there if packets are just queued in the inner discipline rather than having a separate delayed queue. Change to use the dequeue/requeue to peek like TBF does. By doing this potential qlen problems with the old method are avoided. The problems happened when the netem_run that moved packets from the inner discipline to the nested discipline failed (because inner queue was full). This happened in dequeue, so the effective qlen of the netem would be decreased (because of the drop), but there was no way to keep the outer qdisc (caller of netem dequeue) in sync. The problem window is still there since this patch doesn't address the issue of requeue failing in netem_dequeue, but that shouldn't happen since the sequence dequeue/requeue should always work. Long term correct fix is to implement qdisc->peek in all the qdisc's to allow for this (needed by several other qdisc's as well).

From: Marcello Maggioni <hayarms@gmail.com> Problem: Some drives (NEC 3500, TDK 1616N, Mad-dog MD-16XDVD9, RICOH MP5163DA, Memorex DVD9 drive and IO-DATA's too for sure), if a CD/DVD is inserted into the tray when the system is booted and if before the OS bootup the BIOS checked for the presence of a bootable CD/DVD into the drive, during the IDE probe phase the drive may result busy and remain so for the next 25/30 seconds . This cause the drive to be skipped during the booting phase and not begin usable until the next reboot (if the reboot goes well and the drive doesn't timeout again). Solution: Rising the timeout time from 10 seconds to 35 seconds (during these 35 seconds every drive should wake up for sure according to the tests I've done).

From: Stuart Hayes <Stuart_Hayes@dell.com> The system can panic with a null pointer dereference using ide-scsi if PIO is being done on scatter gather pages that are in high memory, because page_address() returns 0. We are actually seeing this using a tape drive. This patch will kmap_atomic() the pages before performing PIO. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@elka.pw.edu.pl>

When testing ATAPI PIO data transfer on the ppc64 platform, __atapi_pio_bytes() got zero when sg_dma_len() is used. I checked the <asm-ppc64/scatterlish.h>, the struct scatterlist is defined as: struct scatterlist { struct page *page; unsigned int offset; unsigned int length; /* For TCE support */ u32 dma_address; u32 dma_length; }; #define sg_dma_address(sg) ((sg)->dma_address) #define sg_dma_len(sg) ((sg)->dma_length) So, if the scatterlist is not DMA mapped, sg_dma_len() will return zero on ppc64. The same problem should occur on the x86-64 platform. On the i386 platform, sg_dma_len() returns sg->length, that's why the problem does not occur on an i386. Changes: - Use sg->length if the scatterlist is not DMA mapped (yet). Signed-off-by: Albert Lee <albertcc@tw.ibm.com>
