* Revert "[PATCH] kthread: update loop.c to use kthread"Linus Torvalds2006-06-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit c7b2eff059fcc2d1b7085ee3d84b79fd657a537b. Hugh Dickins explains: "It seems too little tested: "losetup -d /dev/loop0" fails with EINVAL because nothing sets lo_thread; but even when you patch loop_thread() to set lo->lo_thread = current, it can't survive more than a few dozen iterations of the loop below (with a tmpfs mounted on /tst): j=0 cp /dev/zero /tst while : do let j=j+1 echo "Doing pass $j" losetup /dev/loop0 /tst/zero mkfs -t ext2 -b 1024 /dev/loop0 >/dev/null 2>&1 mount -t ext2 /dev/loop0 /mnt umount /mnt losetup -d /dev/loop0 done it collapses with failed ioctl then BUG_ON(!bio). I think the original lo_done completion was more subtle and safe than the kthread conversion has allowed for." Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * kbuild: check license compatibility when building modulesSam Ravnborg2006-06-091-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modules that uses GPL symbols can no longer be build with kbuild, the build will fail during the modpost step. When a GPL-incompatible module uses a EXPORT_SYMBOL_GPL_FUTURE symbol then warn during modpost so author are actually notified. The actual license compatibility check is shared with the kernel to make sure it is in sync.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the hooks cra_init/cra_exit which are called during a tfm's construction and destruction respectively. This will be used by the instances to allocate child tfm's. For now this lets us get rid of the coa_init/coa_exit functions which are used for exactly that purpose (unlike the dia_init function which is called for each transaction). In fact the coa_exit path is currently buggy as it may get called twice when an error is encountered during initialisation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] all: Pass tfm instead of ctx to algorithmsHerbert Xu2006-06-261-14/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now algorithms have been happy to get a context pointer since they know everything that's in the tfm already (e.g., alignment, block size). However, once we have parameterised algorithms, such information will be specific to each tfm. So the algorithm API needs to be changed to pass the tfm structure instead of the context pointer. This patch is basically a text substitution. The only tricky bit is the assembly routines that need to get the context pointer offset through asm-offsets.h.

This feature is present starting from Intel Core Duo and Intel Core Solo processors. What this means is, the performance monitoring counters and some performance monitoring events are now defined in an architectural way (using cpuid). And there will be no need to check for family/model etc for these architectural events. Below is the patch to use this performance counters in nmi watchdog driver.

| * | | [PATCH] x86_64: Avoid broadcasting NMI IPIsKeith Owens2006-06-261-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some i386/x86_64 systems, sending an NMI IPI as a broadcast will reset the system. This seems to be a BIOS bug which affects machines where one or more cpus are not under OS control. It occurs on HT systems with a version of the OS that is not compiled without HT support. It also occurs when a system is booted with max_cpus=n where 2 <= n < cpus known to the BIOS. The fix is to always send NMI IPI as a mask instead of as a broadcast.

| * | | [PATCH] x86_64: Standardize i386/x86_64 handling of NMI_VECTORKeith Owens2006-06-261-0/+2

Make both behave the same, so IPI 2 is sent as NMI. The crash code was abusing send_IPI_allbutself() by passing a code instead of a vector, it only worked because crash knew about the internal code of send_IPI_allbutself(). Change crash to use NMI_VECTOR instead, and remove the comment about how crash was abusing the function. This patch is a pre-requisite for fixing the problem where sending an IPI as NMI would reboot some Dell Xeon systems. I cannot fix that problem while crash continus to abuse send_IPI_allbutself(). It also removes the inconsistency between i386 and x86_64 for NMI_VECTOR. That will simplify all the RAS code that needs to bring all the cpus to a clean stop, even when one or more cpus are spinning disabled.

I think that is caused by the atomic operations to clear/set the polling flag in thread_info. There is actually no reason to make this atomic - only the idle thread does it to itself, other CPUs only read it. So I moved it into ti->status. Converted i386/x86-64/ia64 for now because that was the easiest way to fix ACPI which also manipulates these flags in its idle function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch hooks Calgary into the build, the x86-64 IOMMU initialization paths, and introduces the Calgary specific bits. The implementation draws inspiration from both PPC (which has support for the same chip but requires firmware support which we don't have on x86-64) and gart. Calgary is different from gart in that it support a translation table per PHB, as opposed to the single gart aperture. Changes from previous version: * Addition of boot-time disablement for bus-level translation/isolation (e.g, enable userspace DMA for things like X) * Usage of newer IOMMU abstraction functions Signed-off-by: Muli Ben-Yehuda <muli@il.ibm.com> Signed-off-by: Jon Mason <jdmason@us.ibm.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
| * | | [PATCH] x86_64: Calgary IOMMU - IOMMU abstractionsJon Mason2006-06-262-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates a new interface for IOMMUs by adding a centralized location for IOMMU allocation (for translation tables/apertures) and IOMMU initialization. In creating these, code was moved around for abstraction, uniformity, and consiceness. Take note of the move of the iommu_setup bootarg parsing code to __setup. This is enabled by moving back the location of the aperture allocation/detection to mem init (which while ugly, was already the location of the swiotlb_init). While a slight departure from the previous patch, I belive this provides the true intention of the previous versions of the patch which changed this code. It also makes the addition of the upcoming calgary code much cleaner than previous patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | swiotlb relies on the gart specific iommu_aperture variable to know if we discovered a hardware IOMMU before swiotlb initialization. Introduce iommu_detected to do the same thing, but in a HW IOMMU neutral manner, in preparation for adding the Calgary HW IOMMU.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are the generic bits needed to enable reliable stack traces based on Dwarf2-like (.eh_frame) unwind information. Subsequent patches will enable x86-64 and i386 to make use of this. Thanks to Andi Kleen and Ingo Molnar, who pointed out several possibilities for improvement.
