2010-03-14ACPI: delete the "acpi=ht" boot optionLen Brown
acpi=ht was important in 2003 -- before ACPI was universally deployed and enabled by default in the major Linux distributions. At that time, there were a fair number of people who or chose to, or needed to, run with acpi=off, yet also wanted access to Hyper-threading. Today we find that many invocations of "acpi=ht" are accidental, and thus is it possible that it is doing more harm than good. In 2.6.34, we warn on invocation of acpi=ht. In 2.6.35, we delete the boot option. Signed-off-by: Len Brown <len.brown@intel.com>

2010-03-14ACPI: remove "acpi=ht" DMI blacklistLen Brown
SuSE added these entries when deploying ACPI in Linux-2.4. I pulled them into Linux-2.6 on 2003-08-09. Over the last 6+ years, several entries have proven to be unnecessary and deleted, while no new entries have been added. Matthew suggests that they now have negative value, and I agree.

Anonymity has some good attributes. Blame avoidance is one of them. I've broad shoulders. It's me, then Dwight Howard... There might be another few of these where ->name or ->dev was used before struct device or net_device was registered.

2010-03-139p: Skip check for mandatory locks when unlockingSachin Prabhu
While investigating a bug, I came across a possible bug in v9fs. The problem is similar to the one reported for NFS by ASANO Masahiro in http://lkml.org/lkml/2005/12/21/334. v9fs_file_lock() will skip locks on file which has mode set to 02666. This is a problem in cases where the mode of the file is changed after a process has obtained a lock on the file. Such a lock will be skipped during unlock and the machine will end up with a BUG in locks_remove_flock(). v9fs_file_lock() should skip the check for mandatory locks when unlocking a file.

2010-03-13x86, k8 nb: Fix boot crash: enable k8_northbridges unconditionally on AMD ↵Borislav Petkov
systems de957628ce7c84764ff41331111036b3ae5bad0f changed setting of the x86_init.iommu.iommu_init function ptr only when GART IOMMU is found. One side effect of it is that num_k8_northbridges is not initialized anymore if not explicitly called. This resulted in uninitialized pointers in <arch/x86/kernel/cpu/intel_cacheinfo.c:amd_calc_l3_indices()>, for example, which uses the num_k8_northbridges thing through node_to_k8_nb_misc(). Fix that through an initcall that runs right after the PCI subsystem and does all the scanning. Then, remove initialization in gart_iommu_init() which is a rootfs_initcall and we're running before that. What is more, since num_k8_northbridges is being used in other places beside GART IOMMU, include it whenever we add AMD CPU support. The previous dependency chain in kconfig contained K8_NB depends on AGP_AMD64|GART_IOMMU which was clearly incorrect. The more natural way in terms of hardware dependency should be AGP_AMD64|GART_IOMMU depends on K8_NB depends on CPU_SUP_AMD && PCI. Make it so Number One!
