2005-05-28[PATCH] intelfb section fixPatrick McManus
On Nov 16 2004 a change to intelfbdrv.c was commited (as part of 0.9.2 it looks like) that added __initdata to all of the module param variables that seems to create the opportunity for an oops. I've recently been chasing an OOPS (http://marc.theaimsgroup.com/?l=linux-kernel&m=111552250920370&w=2) I created by reading every file on the /sys file system and I've traced it back to this code in the intelfbdrv. Though I had root privs in my initial problem report, it turns out they are un-necessary to generate the oops - all you've got to do is "cat /sys/module/intelfb/parameters/mode" enough times and eventually it will oops. This is because sysfs automatically exports all module_param declarations to the sysfs file system.. which means those variables can be dynamically evaluated at any later time, which of course means marking them __initdata is a bad idea ;).. when they happen to be char *'s it is an especially bad idea ;). Applying the patch below clears up the OOPS for me.

2005-05-28[PATCH] ppc32: Fix cpufreq vs. sleep issueBenjamin Herrenschmidt
Recent kernels occasionally trigger a PMU timeout on some mac laptops, typically on wakeup from sleep. This seem to be caused by either a too big latency caused by the cpufreq switch on wakeup from sleep or by an interrupt beeing lost due to the reset of the interrupt controller done during wakeup. This patch makes that code more robust by stopping PMU auto poll activity around cpufreq changes on machines that use the PMU for such changes (long latency switching involving a CPU hard reset and flush of all caches) and by removing the reset of the open pic interrupt controller on wakeup (that can cause the loss of an interrupt and Darwin doesn't do it, so it must not be necessary).

2005-05-28[PATCH] drop note_interrupt() for per-CPU for proper scalingJohn Hawkes
The "unhandled interrupts" catcher, note_interrupt(), increments a global desc->irq_count and grossly damages scaling of very large systems, e.g., >192p ia64 Altix, because of this highly contented cacheline, especially for timer interrupts. 384p is severely crippled, and 512p is unuseable. All calls to note_interrupt() can be disabled by booting with "noirqdebug", but this disables the useful interrupt checking for all interrupts. I propose eliminating note_interrupt() for all per-CPU interrupts. This was the behavior of linux-2.6.10 and earlier, but in 2.6.11 a code restructuring added a call to note_interrupt() for per-CPU interrupts. Besides, note_interrupt() is a bit racy for concurrent CPU calls anyway, as the desc->irq_count++ increment isn't atomic (which, if done, would make scaling even worse).

2005-05-28Input:Adrian Bunk
This patch adds dummy gameport_register_port, gameport_unregister_port and gameport_set_phys functions to gameport.h for the case when a driver can't use gameport. This fixes the compilation of some OSS drivers with GAMEPORT=n without the need to #if inside every single driver. This patch also removes the non-working and now obsolete SOUND_GAMEPORT. This patch is also an alternative solution for ALSA drivers with similar problems (but #if's inside the drivers might have the advantage of saving some more bytes of gameport is not available). The only user-visible change is that for GAMEPORT=m the affected OSS drivers are now allowed to be built statically (but they won't have gameport support).

2005-05-27[PATCH] Note on ACPI build fixAlexander Nyberg
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.

2005-05-27[PATCH] cpuset exit NULL dereference fixPaul Jackson
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.

2005-05-27[PATCH] remove non-cleanroom pwc driver compressionAlan Cox
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.

2005-05-26libata: Fix use-after-iounmapJeff Garzik
Jens Axboe pointed out that the iounmap() call in libata was occurring too early, and some drivers (ahci, probably others) were using ioremap'd memory after it had been unmapped. The patch should address that problem by way of improving the libata driver API: * move ->host_stop() call after all ->port_stop() calls have occurred. * create default helper function ata_host_stop(), and move iounmap() call there. * add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark). sata_qstor appears to require the host-stop-before-port-stop ordering that existed prior to applying the attached patch.
