* [PATCH] adfs: fix filename handlingJames Bursa2007-01-051-1/+1
| | | | | | | | | | Fix filenames on adfs discs being terminated at the first character greater than 128 (adfs filenames are Latin 1). I saw this problem when using a loopback adfs image on a 2.6.17-rc5 x86_64 machine, and the patch fixed it there.

* [PATCH] atiixp: Old drivers/ide layer driver for the ATIIXP hang fixAlan2007-01-051-8/+10
| | | | | | | | | | | | | | | When the old IDE layer calls into methods in the driver during error handling it is essentially random whether ide_lock is already held. This causes a deadlock in the atiixp driver which also uses ide_lock internally for locking. Switch to a private lock instead.

| | | | | | | | | | | | | | | | | | | | | /dev/sr0" Fix http://bugzilla.kernel.org/show_bug.cgi?id=7667 This is because the packet driver tries to send down read/write BLOCK_PC commands that don't use a bio and do not use sg lists. The right fix is to replace all the packet_command stuff in the packet driver by scsi_execute() which needs to be lifted from scsi code to the block code for that. Fix the bug for now. It's not the full way to a generic execute block pc infrastcuture but fixes the bug for the time being.

* [PATCH] KVM: Improve interrupt responseDor Laor2007-01-055-28/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | The current interrupt injection mechanism might delay an interrupt under the following circumstances: - if injection fails because the guest is not interruptible (rflags.IF clear, or after a 'mov ss' or 'sti' instruction). Userspace can check rflags, but the other cases or not testable under the current API. - if injection fails because of a fault during delivery. This probably never happens under normal guests. - if injection fails due to a physical interrupt causing a vmexit so that it can be handled by the host. In all cases the guest proceeds without processing the interrupt, reducing the interactive feel and interrupt throughput of the guest. This patch fixes the situation by allowing userspace to request an exit when the 'interrupt window' opens, so that it can re-inject the interrupt at the right time. Guest interactivity is very visibly improved.

| | | | | | | | | | | | | | KVM does kmalloc() in an atomic section while having preemption disabled via vcpu_load(). Fix this by moving the ->*_msr setup from the vcpu_setup method to the vcpu_create method.

* [PATCH] via82cxxx: fix cable detectionBartlomiej Zolnierkiewicz2007-01-051-73/+65
| | | | | | | | | | | | | | | | This patch fixes 2.6.15 regression, is straightforward and tested. Cable detection got broken probably while converting the driver to support multiple controllers. Cable detection is done by examining how BIOS configured the attached devices. The current code is broken in that it examines the status *after* modifying Clk66 configuration ending up detecting 40c cables as 80c. This patch fixes it.

* [PATCH] PCI: prevent down_read when pci_devices is emptyArd van Breemen2007-01-051-0/+24
| | | | | | | | | | | | | | | | | | | | The pci_find_subsys gets called very early by obsolete ide setup parameters. This is a bogus call since pci is not initialized yet, so the list is empty. But in the mean time, interrupts get enabled by down_read. This can result in a kernel panic when the irq controller gets initialized. This patch checks if the device list is empty before taking the semaphore, and hence will not enable irq's. Furthermore it will inform that it is called while pci_devices is empty as a reminder that the ide code needs to be fixed. The pci_get_subsys can get called in the same manner, and as such is patched in the same manner.

* [PATCH] kernelparams: detect if and which parameter parsing enabled irq'sArd van Breemen2007-01-051-0/+6
| | | | | | | | | | | | | | The parsing of some kernel parameters seem to enable irq's at a stage that irq's are not supposed to be enabled (Particularly the ide kernel parameters).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the G965, the GTT size may be larger than is required to cover the aperture. (In fact, on all hardware we've seen, the GTT is 512KB to the aperture's 256MB). A previous commit forced the aperture size to 512MB on G965 to match GTT, which would likely result in hangs at best if users tried to rely on agpgart's aperture size information. Instead, we use the resource length for the aperture size and the system's reported GTT size when available for the GTT size. Because the MSAC registers which had been read for aperture size detection on i9xx chips just cause a change in the resource size, we can use generic code for aperture detection on all i9xx.

| * | [AGPGART] Remove unnecessary flushes when inserting and removing pages.Thomas Hellstrom2006-12-222-23/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to speed up flipping of pages in and out of the AGP aperture as needed by the new drm memory manager. A number of global cache flushes are removed as well as some PCI posting flushes. The following guidelines have been used: 1) Memory that is only mapped uncached and that has been subject to a global cache flush after the mapping was changed to uncached does not need any more cache flushes. Neither before binding to the aperture nor after unbinding. 2) Only do one PCI posting flush after a sequence of writes modifying page entries in the GATT.
