2009-05-10intel-iommu: Fix tiny theoretical race in write-buffer flush.David Woodhouse
In iommu_flush_write_buffer() we read iommu->gcmd before taking the register_lock, and then we mask in the WBF bit and write it to the register. There is a tiny chance that something else could have _changed_ iommu->gcmd before we take the lock, but after we read it. So we could be undoing that change. Never actually going to have happened in practice, since nothing else changes that register at runtime -- aside from the write-buffer flush it's only ever touched at startup for enabling translation, etc. But worth fixing anyway.

2009-05-10intel-iommu: Clean up handling of "caching mode" vs. IOTLB flushing.David Woodhouse
As we just did for context cache flushing, clean up the logic around whether we need to flush the iotlb or just the write-buffer, depending on caching mode. Fix the same bug in qi_flush_iotlb() that qi_flush_context() had -- it isn't supposed to be returning an error; it's supposed to be returning a flag which triggers a write-buffer flush. Remove some superfluous conditional write-buffer flushes which could never have happened because they weren't for non-present-to-present mapping changes anyway.

2009-05-10intel-iommu: Clean up handling of "caching mode" vs. context flushing.David Woodhouse
It really doesn't make a lot of sense to have some of the logic to handle caching vs. non-caching mode duplicated in qi_flush_context() and __iommu_flush_context(), while the return value indicates whether the caller should take other action which depends on the same thing. Especially since qi_flush_context() thought it was returning something entirely different anyway. This patch makes qi_flush_context() and __iommu_flush_context() both return void, removes the 'non_present_entry_flush' argument and makes the only call site which _set_ that argument to 1 do the right thing.

2009-04-29Intel IOMMU Pass Through SupportFenghua Yu
The patch adds kernel parameter intel_iommu=pt to set up pass through mode in context mapping entry. This disables DMAR in linux kernel; but KVM still runs on VT-d and interrupt remapping still works. In this mode, kernel uses swiotlb for DMA API functions but other VT-d functionalities are enabled for KVM. KVM always uses multi level translation page table in VT-d. By default, pass though mode is disabled in kernel. This is useful when people don't want to enable VT-d DMAR in kernel but still want to use KVM and interrupt remapping for reasons like DMAR performance concern or debug purpose.

2009-04-21driver synchronization: make scsi_wait_scan more advancedArjan van de Ven
There is currently only one way for userspace to say "wait for my storage device to get ready for the modules I just loaded": to load the scsi_wait_scan module. Expectations of userspace are that once this module is loaded, all the (storage) devices for which the drivers were loaded before the module load are present. Now, there are some issues with the implementation, and the async stuff got caught in the middle of this: The existing code only waits for the scsy async probing to finish, but it did not take into account at all that probing might not have begun yet. (Russell ran into this problem on his computer and the fix works for him) This patch fixes this more thoroughly than the previous "fix", which had some bad side effects (namely, for kernel code that wanted to wait for the scsi scan it would also do an async sync, which would deadlock if you did it from async context already.. there's a report about that on lkml): The patch makes the module first wait for all device driver probes, and then it will wait for the scsi parallel scan to finish.

2009-04-21PERCPU: Collect the DECLARE/DEFINE declarations togetherDavid Howells
Collect the DECLARE/DEFINE declarations together in linux/percpu-defs.h so that they're in one place, and give them descriptive comments, particularly the SHARED_ALIGNED variant. It would be nice to collect these in linux/percpu.h, but that's not possible without sorting out the severe #include recursion between the x86 arch headers and the general headers (and possibly other arches too).

2009-04-21FRV: Fix the section attribute on UP DECLARE_PER_CPU()David Howells
In non-SMP mode, the variable section attribute specified by DECLARE_PER_CPU() does not agree with that specified by DEFINE_PER_CPU(). This means that architectures that have a small data section references relative to a base register may throw up linkage errors due to too great a displacement between where the base register points and the per-CPU variable. On FRV, the .h declaration says that the variable is in the .sdata section, but the .c definition says it's actually in the .data section. The linker throws up the following errors: kernel/built-in.o: In function `release_task': kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o To fix this, DECLARE_PER_CPU() should simply apply the same section attribute as does DEFINE_PER_CPU(). However, this is made slightly more complex by virtue of the fact that there are several variants on DEFINE, so these need to be matched by variants on DECLARE.

Commit a6dc60f8975ad96d162915e07703a4439c80dcf0 ("vmscan: rename sc.may_swap to may_unmap") removed the may_swap flag, but memcg had used it as a flag for "we need to use swap?", as the name indicate. And in the current implementation, memcg cannot reclaim mapped file caches when mem+swap hits the limit. re-introduce may_swap flag and handle it at get_scan_ratio(). This patch doesn't influence any scan_control users other than memcg.

2009-04-21frv: insert PCI root bus resources for the MB93090 devel motherboardDavid Howells
Insert PCI root bus resources for the FRV-based MB93090 development kit motherboard. This is required because the CPU's window onto the PCI bus address space is considerably smaller than the CPU's full address space and non-PCI devices lie outside of the PCI window that we might want to access. Without this patch, the PCI root bus uses the platform-level bus resources, and these are then confined to the PCI window, thus making platform_device_add() reject devices outside of this window.

2009-04-21Btrfs: fix btrfs fallocate oops and deadlockChris Mason
Btrfs fallocate was incorrectly starting a transaction with a lock held on the extent_io tree for the file, which could deadlock. Strictly speaking it was using join_transaction which would be safe, but it is better to move the transaction outside of the lock. When preallocated extents are overwritten, btrfs_mark_buffer_dirty was being called on an unlocked buffer. This was triggering an assertion and oops because the lock is supposed to be held. The bug was calling btrfs_mark_buffer_dirty on a leaf after btrfs_del_item had been run. btrfs_del_item takes care of dirtying things, so the solution is a to skip the btrfs_mark_buffer_dirty call in this case.

2009-04-21NFS: Fix the XDR iovec calculation in nfs3_xdr_setaclargsTrond Myklebust
Commit ae46141ff08f1965b17c531b571953c39ce8b9e2 (NFSv3: Fix posix ACL code) introduces a bug in the calculation of the XDR header iovec. In the case where we are inlining the acls, we need to adjust the length of the iovec req->rq_svec, in addition to adjusting the total buffer length.
