2011-05-26xen: cleancache shim to Xen Transcendent MemoryDan Magenheimer2-0/+265
This patch provides a shim between the kernel-internal cleancache API (see Documentation/mm/cleancache.txt) and the Xen Transcendent Memory ABI (see http://oss.oracle.com/projects/tmem). Xen tmem provides "hypervisor RAM" as an ephemeral page-oriented pseudo-RAM store for cleancache pages, shared cleancache pages, and frontswap pages. Tmem provides enterprise-quality concurrency, full save/restore and live migration support, compression and deduplication. A presentation showing up to 8% faster performance and up to 52% reduction in sectors read on a kernel compile workload, despite aggressive in-kernel page reclamation ("self-ballooning") can be found at: http://oss.oracle.com/projects/tmem/dist/documentation/presentations/TranscendentMemoryXenSummit2010.pdf Signed-off-by: Dan Magenheimer <dan.magenheimer@oracle.com> Reviewed-by: Jeremy Fitzhardinge <jeremy@goop.org> Cc: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Cc: Matthew Wilcox <matthew@wil.cx> Cc: Nick Piggin <npiggin@kernel.dk> Cc: Mel Gorman <mel@csn.ul.ie> Cc: Rik Van Riel <riel@redhat.com> Cc: Jan Beulich <JBeulich@novell.com> Cc: Chris Mason <chris.mason@oracle.com> Cc: Andreas Dilger <adilger@sun.com> Cc: Ted Ts'o <tytso@mit.edu> Cc: Mark Fasheh <mfasheh@suse.com> Cc: Joel Becker <joel.becker@oracle.com> Cc: Nitin Gupta <ngupta@vflare.org>

The bonding driver initializes some data structures only after its ndo_open routine is called. Among them is the initalization of the alb tx and rx hash locks. So if we add or remove a slave without first opening the bond master device, we run the risk of trying to lock/unlock a spinlock that has garbage for data in it, which results in our above softlock. Note that sometimes this works, because in many cases an unlocked spinlock has the raw_lock parameter initialized to zero (meaning that the kzalloc of the net_device private data is equivalent to calling spin_lock_init), but thats not true in all cases, and we aren't guaranteed that condition, so we need to pass the relevant spinlocks through the spin_lock_init function. Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to the ndo_init path, so they are ready for use by the bond_store_slaves path. Change notes: v2) Based on conversation with Jay and Nicolas it seems that the ability to enslave devices while the bond master is down should be safe to do. As such this is an outlier bug, and so instead we'll just initalize the errant spinlocks in the init path rather than the open path, solving the problem. We'll also remove the warnings about the bond being down during enslave operations, since it should be safe v3) Fix spelling error Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Reported-by: jtluka@redhat.com CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: nicolas.2p.debian@gmail.com CC: "David S.

2011-05-26via-velocity: don't annotate MAC registers as packedUlrich Hecht1-1/+1
On ARM, memory accesses through packed pointers behave in unexpected ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163 for discussion. In this particular case, 32-bit I/O registers are accessed bytewise, causing incorrect setting of the DMA address registers which in turn leads to an error interrupt storm that brings the system to a halt. Since the mac_regs structure does not need any packing anyway, this patch simply removes the attribute to fix the issue. Signed-off-by: Ulrich Hecht <uli@suse.de> Signed-off-by: David S.

2011-05-26mmc: core: eMMC bus width may not work on all platformsPhilip Rakity1-10/+102
CMD19 -- The offical way to validate bus widths from the JEDEC spec does not work on all platforms. Some platforms that use PCI/PCIe to connect their SD controllers are known to fail. If the quirk MMC_BUS_WIDTH_TEST is not defined we try to figure out the bus width by reading the ext_csd at different bus widths and compare this against the ext_csd read in 1 bit mode. If no ext_csd is available we default to 1 bit operations. Code has been tested on mmp2 against 8 bit eMMC and Transcend 2GB card that is known to not work in 4 bit mode. The physical pins on the card are not present to support 4 bit operation. Signed-off-by: Philip Rakity <prakity@marvell.com> Signed-off-by: Chris Ball <cjb@laptop.org>

2011-05-26RDMA/cma: Add support for netlink statistics exportNir Muchtar1-0/+99
Add callbacks and data types for statistics export of all current devices/ids. The schema for RDMA CM is a series of netlink messages. Each one contains an rdma_cm_stat struct. Additionally, two netlink attributes are created for the addresses for each message (if applicable). Their types used are: RDMA_NL_RDMA_CM_ATTR_SRC_ADDR (The source address for this ID) RDMA_NL_RDMA_CM_ATTR_DST_ADDR (The destination address for this ID) sockaddr_* structs are encapsulated within these attributes. In other words, every transaction contains a series of messages like: -------message 1------- struct rdma_cm_id_stats { __u32 qp_num; __u32 bound_dev_if; __u32 port_space; __s32 pid; __u8 cm_state; __u8 node_type; __u8 port_num; __u8 reserved; } RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute - contains the source address RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute - contains the destination address -------end 1------- -------message 2------- struct rdma_cm_id_stats RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute -------end 2------- Signed-off-by: Nir Muchtar <nirm@voltaire.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2011-05-26RDMA/cma: Pass QP type into rdma_create_id()Sean Hefty3-24/+40
The RDMA CM currently infers the QP type from the port space selected by the user. In the future (eg with RDMA_PS_IB or XRC), there may not be a 1-1 correspondence between port space and QP type. For netlink export of RDMA CM state, we want to export the QP type to userspace, so it is cleaner to explicitly associate a QP type to an ID. Modify rdma_create_id() to allow the user to specify the QP type, and use it to make our selections of datagram versus connected mode.

2011-05-25hwmon: New driver for the SMSC EMC6W201Jean Delvare3-0/+550
This is a new driver for the SMSC EMC6W201 hardware monitoring device. The device is functionally close to the EMC6D100 series, but is register-incompatible.

2011-05-25hwmon: (abituguru) Depend on DMIJean Delvare3-18/+2
The abituguru drivers are only built on X86, where DMI support is now enabled by default. So let these drivers depend on DMI, for the following gains: * Robustness and safety. Detection of these devices is weak and uses non-standard methods, it should really be limited to Abit boards unless the user explicitly asks otherwise. * Code simplicity. The code is easier to read without ifdefs. * Better build testing coverage. Now there's only one way to build the drivers, so no risk of build failure on exotic systems.

2011-05-25hwmon: (it87) Use request_muxed_regionNat Gurumoorthy1-12/+19
Serialize access to the hardware by using "request_muxed_region" macro defined by Alan Cox. Call to this macro will hold off the requestor if the resource is currently busy. "superio_enter" will return an error if call to "request_muxed_region" fails. Rest of the code change is to ripple an error return from superio_enter to the top level.

2011-05-25Move ACPI power meter driver to hwmonJean Delvare5-12/+11
As discussed earlier, the ACPI power meter driver would better live in drivers/hwmon, as its only purpose is to create hwmon-style interfaces for ACPI 4.0 power meter devices. Users are more likely to look for it there, and less likely to accidentally hide it by unselecting its dependencies. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: "Darrick J.

AMDs upcoming CPUs use the same mechanism for the internal temperature reporting as the Fam10h CPUs, so we just needed to add the appropriate PCI-ID to the list.
