2010-05-15ARM: 6132/1: PL330: Add common core driverJassi Brar
PL330 is a configurable DMA controller PrimeCell device. The register map of the device is well defined. The configuration of a particular implementation can be read from the six configuration registers CR0-4,Dn. This patch implements a driver for the specification:- http://infocenter.arm.com/help/topic/com.arm.doc.ddi0424a/DDI0424A_dmac_pl330_r0p0_trm.pdf The exported interface should be sufficient to implement a driver for any DMA API.

2010-05-15ARM: 6094/1: Extend cache-l2x0 to support the 16-way PL310Jason McMullan
The L310 cache controller's interface is almost identical to the L210. One major difference is that the PL310 can have up to 16 ways. This change uses the cache's part ID and the Associativity bits in the AUX_CTRL register to determine the number of ways. Also, this version prints out the CACHE_ID and AUX_CTRL registers.

2010-05-15ARM: convert /proc/cpu/aligment to seq_fileAlexey Dobriyan
Convert code away from ->read_proc/->write_proc interfaces. Switch to proc_create()/proc_create_data() which makes addition of proc entries reliable wrt NULL ->proc_fops, NULL ->data and so on. Problem with ->read_proc et al is described here commit 786d7e1612f0b0adb6046f19b906609e4fe8b1ba "Fix rmmod/read/write races in /proc entries" This patch is part of an effort to remove the old simple procfs PAGE_SIZE buffer interface.

2010-04-14ARM: remove unnecessary cache flushRussell King
This cache flush occurs when we first insert a page into the page tables, where a page did not exist previously.

2010-03-18Btrfs: fix the inode ref searches done by btrfs_search_path_in_treeChris Mason
This is used by the inode lookup ioctl to follow all the backrefs up to the subvol root. But the search being done would sometimes land one past the last item in the leaf instead of finding the backref. This changes the search to look for the highest possible backref and hop back one item. It also fixes a leaked path on failure to find the root. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2010-03-18Btrfs: allow treeid==0 in the inode lookup ioctlChris Mason
When a root id of 0 is sent to the inode lookup ioctl, it will use the root of the file we're ioctling and pass the root id back to userland along with the results. This allows userland to do searches based on that root later on. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2010-03-18Btrfs: return keys for large items to the search ioctlChris Mason
The search ioctl was skipping large items entirely (ones that are too big for the results buffer). This changes things to at least copy the item header so that we can send information about the item back to userland. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2010-03-18Btrfs: fix key checks and advance in the search ioctlChris Mason
The search ioctl was working well for finding tree roots, but using it for generic searches requires a few changes to how the keys are advanced. This treats the search control min fields for objectid, type and offset more like a key, where we drop the offset to zero once we bump the type, etc. The downside of this is that we are changing the min_type and min_offset fields during the search, and so the ioctl caller needs extra checks to make sure the keys in the result are the ones it wanted. This also changes key_in_sk to use btrfs_comp_cpu_keys, just to make things more readable. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2010-03-18of: Fix comparison of "compatible" propertiesGrant Likely
Commit 7c7b60cb87547b1664a4385c187f029bf514a737 "of: put default string compare and #a/s-cell values into common header" Breaks various things on powerpc due to using strncasecmp instead of strcasecmp for comparing against "compatible" strings. This causes things like the 4xx PCI code to fail miserably due to the partial matches in code like this: for_each_compatible_node(np, NULL, "ibm,plb-pcix") ppc4xx_probe_pcix_bridge(np); for_each_compatible_node(np, NULL, "ibm,plb-pci") ppc4xx_probe_pci_bridge(np); It's not quite right to do partial name match. Entries in a compatible list are meant to be matched whole. If a device is compatible with both "foo" and "foo1", then the device should have both strings in its "compatible" property. This patch reverts powerpc and microblaze us to use strcasecmp.

2010-03-17memory hotplug: allow setting of phys_deviceHeiko Carstens
/sys/devices/system/memory/memoryX/phys_device is supposed to contain the number of the physical device that the corresponding piece of memory belongs to. In case a physical device should be replaced or taken offline for whatever reason it is necessary to set all corresponding memory pieces offline. The current implementation always sets phys_device to '0' and there is no way or hook to change that. Seems like there was a plan to implement that but it wasn't finished for whatever reason. So add a weak function which architectures can override to actually set the phys_device from within add_memory_block().

2010-03-17jffs2: fix up rb_root initializations to use RB_ROOTVenkatesh Pallipadi
jffs2 uses rb_node = NULL; to zero rb_root. The problem with this is that 17d9ddc72fb8bba0d4f678 ("rbtree: Add support for augmented rbtrees") in the linux-next tree adds a new field to that struct which needs to be NULL as well. This patch uses RB_ROOT as the intializer so all of the relevant fields will be NULL'd.

2010-03-17ahci: use BIOS date in broken_suspend listTejun Heo
HP is recycling both DMI_PRODUCT_NAME and DMI_BIOS_VERSION making ahci_broken_suspend() trigger for later products which are not affected by the original problems. Match BIOS date instead of version and add references to bko's so that full information can be found easier later.

bko#15481 shows that we're missing some NVIDIA ahci PCI IDs. Peer Chen confirms that IDs 0x580-0x58f are reserved for cases where Linux ID option is selected in the BIOS and are only used for mcp65-73. Add 0x0581-0x058f. http://bugzilla.kernel.org/show_bug.cgi?id=15481 Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Peer Chen <pchen@nvidia.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
