If there are devices that use interrupts over a suspend event, ACPI must restore the PCI interrupt links on resume. Anything else breaks any device that hasn't been converted to the new (dubious) PM rules. Drivers that need the irq free/re-aquire sequence can be done one by one independently of this one.

There's no real guarantee that handle_mm_fault() will always be able to break a COW situation - if an update from another thread ends up modifying the page table some way, handle_mm_fault() may end up requiring us to re-try the operation. That's normally fine, but get_user_pages() ended up re-trying it as a read, and thus a write access could in theory end up losing the dirty bit or be done on a page that had not been properly COW'ed. This makes get_user_pages() always retry write accesses as write accesses by making "follow_page()" require that a writable follow has the dirty bit set. That simplifies the code and solves the race: if the COW break fails for some reason, we'll just loop around and try again. Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

Reported by: Jochen Hein (Bugzilla Bug 4312) When there is disk I/O happening, the framebuffer has a little snow on the screen. Once I/O has finished, no garbage remains on screen. This bug was explained by: Knut Petersen Most important is CRTC register 2f, signal quality is also improved for higher vclk values by changing set_vclk() according to the X drivers and cyblafb.c The fix is to set the performance register (0x2f) with a more stable value.

Reported by: Jochen Hein (Bugzilla Bug 4386) booting leaves the end of long lines in the last line on screen when scrolling. When X is running, scrolling puts garbage on the screen (looks like X data) Console switch fixes the screen. Behaviour seems to be identical with noaccel and without on the video=tridentfb parameter in lilo.conf. This bug was explained by: Knut_Petersen Acceleration is broken for all BLADE 3D chips for all versions of kernel 2.6 except for 32bit modes. Most important reason is that the u32 col parameter of the graphics engine needs the color value replicated to all u8 of the u32 (8bit modes) and to both u16 of the u32. Fix color value passed to graphics engine, verified by the reporter. Signed-off-by: NAntonino Daplas <adaplas@pol.net> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

This removes sys_set_zone_reclaim() for now. While i'm sure Martin is trying to solve a real problem, we must not hard-code an incomplete and insufficient approach into a syscall, because syscalls are pretty much for eternity. I am quite strongly convinced that this syscall must not hit v2.6.13 in its current form. Firstly, the syscall lacks basic syscall design: e.g. it allows the global setting of VM policy for unprivileged users. (!) [ Imagine an Oracle installation and a SAP installation on the same NUMA box fighting over the 'optimal' setting for this flag. What will they do? Will they try to set the flag to their own preferred value every second or so? ] Secondly, it was added based on a single datapoint from Martin: http://marc.theaimsgroup.com/?l=linux-mm&m=111763597218177&w=2 where Martin characterizes the numbers the following way: ' Run-to-run variability for "make -j" is huge, so these numbers aren't terribly useful except to see that with reclaim the benchmark still finishes in a reasonable amount of time. ' in other words: the fundamental problem has likely not been solved, only a tendential move into the right direction has been observed, and a handful of numbers were picked out of a set of hugely variable results, without showing the variability data. How much variance is there run-to-run? I'd really suggest to first walk the walk and see what's needed to get stable & predictable kernel compilation numbers on that NUMA box, before adding random syscalls to tune a particular aspect of the VM ... which approach might not even matter once the whole picture has been analyzed and understood! The third, most important point is that the syscall exposes VM tuning internals in a completely unstructured way. What sense does it make to have a _GLOBAL_ per-node setting for 'should we go to another node for reclaim'? If then it might make sense to do this per-app, via numalib or so. The change is minimalistic in that it doesnt remove the syscall and the underlying infrastructure changes, only the user-visible changes. We could perhaps add a CAP_SYS_ADMIN-only sysctl for this hack, a'ka /proc/sys/vm/swappiness, but even that looks quite counterproductive when the generic approach is that we are trying to reduce the number of external factors in the VM balance picture.

When you rm a watch, an IN_IGNORED event is sent down the event queue with the watch descriptor that you just rm'd. If you then add a watch you could get the ignored watch's wd and if you haven't read the entire event queue, user space will think that it's newly created watch was just ignored. To avoid this problem we just use idr_get_new_above instead of idr_get_new.

SCSI=m must disallow static drivers. The problem is that all the SATA drivers depend on SCSI_SATA. With SCSI=m and SCSI_SATA=y this allows the static enabling of the SATA drivers with unwanted effects, e.g.: - SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y -> SCSI_ATA_ADMA is built statically but scsi/built-in.o is not linked into the kernel - SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y, SCSI_SATA_AHCI=m -> SCSI_ATA_ADMA and libata are built statically but scsi/built-in.o is not linked into the kernel, SCSI_SATA_AHCI is built modular (unresolved symbols due to missing libata) Signed-off-by: NAdrian Bunk <bunk@stusta.de> Cc: Jeff Garzik <jgarzik@pobox.com> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NJeff Garzik <jgarzik@pobox.com>

The bug is evident when it is seen once. dst gc timer was backed off, when gc queue is not empty. But this means that timer quickly backs off, if at least one destination remains in use. Normally, the bug is invisible, because adding new dst entry to queue cancels the backoff. But it shots deadly with destination cache overflow when new destinations are not released for long time f.e. after an interface goes down. The fix is to cancel backoff when something was released.

Tunnel modules used to obtain module refcount each time when some tunnel was created, which meaned that tunnel could be unloaded only after all the tunnels are deleted. Since killing old MOD_*_USE_COUNT macros this protection has gone.

The patch adds boundary check for the MAX_GSI_NUM. Same as the update for i386, the patch addresses a problem with ACPI SCI IRQ. The patch corrects the code such that SCI IRQ is skipped and duplicate entry is avoided. The VIA chipset uses 4-bit IRQ register for internal interrupt routing, and therefore cannot handle IRQ numbers assigned to its devices. The patch corrects this problem by allowing PCI IRQs below 16.
