2011-06-21iommu/amd: Move missing parts to drivers/iommuJoerg Roedel7-9/+11
A few parts of the driver were missing in drivers/iommu. Move them there to have the complete driver in that directory. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-06-21iommu: Move iommu Kconfig entries to submenuJoerg Roedel1-0/+13
For better navigation this patch moves the drivers/iommu drivers into its own submenu in Kconfig. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-06-21x86/ia64: intel-iommu: move to drivers/iommu/Ohad Ben-Cohen12-80/+62
This should ease finding similarities with different platforms, with the intention of solving problems once in a generic framework which everyone can use. Note: to move intel-iommu.c, the declaration of pci_find_upstream_pcie_bridge() has to move from drivers/pci/pci.h to include/linux/pci.h. This is handled in this patch, too. As suggested, also drop DMAR's EXPERIMENTAL tag while we're at it. Compile-tested on x86_64. Signed-off-by: Ohad Ben-Cohen <ohad@wizery.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

2011-06-14drivers: iommu: move to a dedicated folderOhad Ben-Cohen9-10/+9
Create a dedicated folder for iommu drivers, and move the base iommu implementation over there. Grouping the various iommu drivers in a single location will help finding similar problems shared by different platforms, so they could be solved once, in the iommu framework, instead of solved differently (or duplicated) in each driver.

2011-06-12vlan: Fix the ingress VLAN_FLAG_REORDER_HDR checkJiri Pirko4-31/+61
Testing of VLAN_FLAG_REORDER_HDR does not belong in vlan_untag but rather in vlan_do_receive. Otherwise the vlan header will not be properly put on the packet in the case of vlan header accelleration. As we remove the check from vlan_check_reorder_header rename it vlan_reorder_header to keep the naming clean. Fix up the skb->pkt_type early so we don't look at the packet after adding the vlan tag, which guarantees we don't goof and look at the wrong field. Use a simple if statement instead of a complicated switch statement to decided that we need to increment rx_stats for a multicast packet. Hopefully at somepoint we will just declare the case where VLAN_FLAG_REORDER_HDR is cleared as unsupported and remove the code. Until then this keeps it working correctly. Signed-off-by: Eric W.

When encountering an EIO while reading from a nodatasum extent, we insert an error record into the inode's failure tree. btrfs_readpage_end_io_hook returns early for nodatasum inodes. We'd better clear the failure tree in that case, otherwise the kernel complains about BUG extent_state: Objects remaining on kmem_cache_close() on rmmod.

2011-06-11btrfs: fix unlocked access of delalloc_inodesDavid Sterba1-2/+1
list_splice_init will make delalloc_inodes empty, but without a spinlock around, this may produce corrupted list head, accessed in many placess, The race window is very tight and nobody seems to have hit it so far.

2011-06-11btrfs: remove 64bit alignment padding to allow extent_buffer to fit into one ↵richard kennedy1-1/+1
fewer cacheline Reorder extent_buffer to remove 8 bytes of alignment padding on 64 bit builds. This shrinks its size to 128 bytes allowing it to fit into one fewer cache lines and allows more objects per slab in its kmem_cache. slabinfo extent_buffer reports :- before:- Sizes (bytes) Slabs ---------------------------------- Object : 136 Total : 123 SlabObj: 136 Full : 121 SlabSiz: 4096 Partial: 0 Loss : 0 CpuSlab: 2 Align : 8 Objects: 30 after :- Object : 128 Total : 4 SlabObj: 128 Full : 2 SlabSiz: 4096 Partial: 0 Loss : 0 CpuSlab: 2 Align : 8 Objects: 32 Signed-off-by: Richard Kennedy <richard@rsk.demon.co.uk> Signed-off-by: Chris Mason <chris.mason@oracle.com>
2011-06-11Btrfs: clear current->journal_info on async transaction commitSage Weil1-1/+4
Normally current->jouranl_info is cleared by commit_transaction. For an async snap or subvol creation, though, it runs in a work queue. Clear it in btrfs_commit_transaction_async() to avoid leaking a non-NULL journal_info when we return to userspace. When the actual commit runs in the other thread it won't care that it's current->journal_info is already NULL.

2011-06-11Btrfs: make sure to recheck for bitmaps in clustersChris Mason1-4/+5
Josef recently changed the free extent cache to look in the block group cluster for any bitmaps before trying to add a new bitmap for the same offset. This avoids BUG_ON()s due covering duplicate ranges. But it didn't go quite far enough. A given free range might span between one or more bitmaps or free space entries. The code has looping to cover this, but it doesn't check for clustered bitmaps every time. This shuffles our gotos to check for a bitmap in the cluster for every new bitmap entry we try to add.
