2013-08-23ata: acpi: rework the ata acpi bind supportAaron Lu1-2/+0
Binding ACPI handle to SCSI device has several drawbacks, namely: 1 During ATA device initialization time, ACPI handle will be needed while SCSI devices are not created yet. So each time ACPI handle is needed, instead of retrieving the handle by ACPI_HANDLE macro, a namespace scan is performed to find the handle for the corresponding ATA device. This is inefficient, and also expose a restriction on calling path not holding any lock. 2 The binding to SCSI device tree makes code complex, while at the same time doesn't bring us any benefit. All ACPI handlings are still done in ATA module, not in SCSI. Rework the ATA ACPI binding code to bind ACPI handle to ATA transport devices(ATA port and ATA device). The binding needs to be done only once, since the ATA transport devices do not go away with hotplug. And due to this, the flush_work call in hotplug handler for ATA bay is no longer needed. Tested on an Intel test platform for binding and runtime power off for ODD(ZPODD) and hard disk; on an ASUS S400C for binding and normal boot and S3, where its SATA port node has _SDD and _GTF control methods when configured as an AHCI controller and its PATA device node has _GTF control method when configured as an IDE controller. SATA PMP binding and ATA hotplug is not tested. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Tested-by: Dirk Griesbach <spamthis@freenet.de> Signed-off-by: Tejun Heo <tj@kernel.org>
2013-08-23math64: New separate div64_u64_rem helperMike Snitzer1-0/+13
Commit f792685006274a850e6cc0ea9ade275ccdfc90bc ("math64: New div64_u64_rem helper") implemented div64_u64 in terms of div64_u64_rem. But div64_u64_rem was removed because it slowed down div64_u64 (and there were no other users of div64_u64_rem). Device Mapper's I/O statistics support has a need for div64_u64_rem; reintroduce this helper as a separate method that doesn't slow down div64_u64, especially on 32-bit systems.

2013-08-23dmaengine: make dma_submit_error() return an error codeDan Carpenter1-1/+4
The problem here is that the dma_xfer() functions in drivers/ata/pata_arasan_cf.c and drivers/mtd/nand/fsmc_nand.c expect dma_submit_error() to return an error code so they return 1 when they intended to return a negative. So far as I can tell, none of the ->tx_submit() functions ever do return error codes so this patch should have no effect in the current code. I also changed it from a define to an inline.

2013-08-22Revert "x86 get_unmapped_area(): use proper mmap base for bottom-up direction"Linus Torvalds1-1/+0
This reverts commit df54d6fa54275ce59660453e29d1228c2b45a826. The commit isn't necessarily wrong, but because it recalculates the random mmap_base every time, it seems to confuse user memory allocators that expect contiguous mmap allocations even when the mmap address isn't specified. In particular, the MATLAB Java runtime seems to be unhappy. See https://bugzilla.kernel.org/show_bug.cgi?id=60774 So we'll want to apply the random offset only once, and Radu has a patch for that.

2013-08-22PCI: Simplify pcie_bus_configure_settings() interfaceBjorn Helgaas1-1/+1
Based on a patch by Jon Mason (see URL below). All users of pcie_bus_configure_settings() pass arguments of the form "bus, bus->self->pcie_mpss". The "mpss" argument is redundant since we can easily look it up internally. In addition, all callers check "bus->self" for NULL, which we can also do internally. This patch simplifies the interface and the callers. No functional change.

2013-08-22[SCSI] zfcp: fix lock imbalance by reworking request queue lockingMartin Peschke1-0/+57
This patch adds wait_event_interruptible_lock_irq_timeout(), which is a straight-forward descendant of wait_event_interruptible_timeout() and wait_event_interruptible_lock_irq(). The zfcp driver used to call wait_event_interruptible_timeout() in combination with some intricate and error-prone locking. Using wait_event_interruptible_lock_irq_timeout() as a replacement nicely cleans up that locking. This rework removes a situation that resulted in a locking imbalance in zfcp_qdio_sbal_get(): BUG: workqueue leaked lock or atomic: events/1/0xffffff00/10 last function: zfcp_fc_wka_port_offline+0x0/0xa0 [zfcp] It was introduced by commit c2af7545aaff3495d9bf9a7608c52f0af86fb194 "[SCSI] zfcp: Do not wait for SBALs on stopped queue", which had a new code path related to ZFCP_STATUS_ADAPTER_QDIOUP that took an early exit without a required lock being held. The problem occured when a special, non-SCSI I/O request was being submitted in process context, when the adapter's queues had been torn down. In this case the bug surfaced when the Fibre Channel port connection for a well-known address was closed during a concurrent adapter shut-down procedure, which is a rare constellation. This patch also fixes these warnings from the sparse tool (make C=1): drivers/s390/scsi/zfcp_qdio.c:224:12: warning: context imbalance in 'zfcp_qdio_sbal_check' - wrong count at exit drivers/s390/scsi/zfcp_qdio.c:244:5: warning: context imbalance in 'zfcp_qdio_sbal_get' - unexpected unlock Last but not least, we get rid of that crappy lock-unlock-lock sequence at the beginning of the critical section. It is okay to call zfcp_erp_adapter_reopen() with req_q_lock held.

2013-08-21drivers: base: use standard device online/offline for state changeSeth Jennings1-10/+3
There are two ways to set the online/offline state for a memory block: echo 0|1 > online and echo online|online_kernel|online_movable|offline > state. The state attribute can online a memory block with extra data, the "online type", where the online attribute uses a default online type of ONLINE_KEEP, same as echo online > state. Currently there is a state_mutex that provides consistency between the memory block state and the underlying memory. The problem is that this code does a lot of things that the common device layer can do for us, such as the serialization of the online/offline handlers using the device lock, setting the dev->offline field, and calling kobject_uevent(). This patch refactors the online/offline code to allow the common device_[online|offline] functions to be used. The result is a simpler and more common code path for the two state setting mechanisms. It also removes the state_mutex from the struct memory_block as the memory block device lock provides the state consistency. No functional change is intended by this patch.

This patch moves the generalized implementation of of_get_cpu_node from PowerPC to DT core library, thereby adding support for retrieving cpu node for a given logical cpu index on any architecture. The CPU subsystem can now use this function to assign of_node in the cpu device while registering CPUs. It is recommended to use these helper function only in pre-SMP/early initialisation stages to retrieve CPU device node pointers in logical ordering. Once the cpu devices are registered, it can be retrieved easily from cpu device of_node which avoids unnecessary parsing and matching.

2013-08-21sh_eth: remove 'register_type' field from 'struct sh_eth_plat_data'Sergei Shtylyov1-7/+0
Now that the 'register_type' field of the 'sh_eth' driver's platform data is not used by the driver anymore, it's time to remove it and its initializers from the SH platform code. Also move *enum* declaring values for this field from <linux/sh_eth.h> to the local driver's header file as they're only needed by the driver itself now...

2013-08-21quota: Add a new quotactl command Q_XGETQSTATVChandra Seetharaman1-0/+1
XFS now supports three types of quotas (user, group and project). Current version of Q_XGETSTAT has support for only two types of quotas. In order to support three types of quotas, the interface, specifically struct fs_quota_stat, need to be expanded. Current version of fs_quota_stat does not allow expansion without breaking backward compatibility. So, a quotactl command and new fs_quota_stat structure need to be added. This patch adds a new command Q_XGETQSTATV to quotactl() which takes a new data structure fs_quota_statv. This new data structure provides support for future expansion and backward compatibility. Callers of the new quotactl command have to set the version of the data structure being passed, and kernel will fill as much data as requested. If the kernel does not support the user-space provided version, EINVAL will be returned. User-space can reduce the version number and call the same quotactl again.

Before this patch, you had to use ctnetlink instead, thus, we save the conntrack lookup. * Export xt_rpfilter and xt_HMARK header files, from Nicolas Dichtel. ==================== Signed-off-by: David S.

2013-08-20jiffies: Avoid undefined behavior from signed overflowPaul E. McKenney1-4/+4
According to the C standard 3.4.3p3, overflow of a signed integer results in undefined behavior. This commit therefore changes the definitions of time_after(), time_after_eq(), time_after64(), and time_after_eq64() to avoid this undefined behavior. The trick is that the subtraction is done using unsigned arithmetic, which according to 6.2.5p9 cannot overflow because it is defined as modulo arithmetic. This has the added (though admittedly quite small) benefit of shortening four lines of code by four characters each. Note that the C standard considers the cast from unsigned to signed to be implementation-defined, see 6.3.1.3p3. However, on a two's-complement system, an implementation that defines anything other than a reinterpretation of the bits is free to come to me, and I will be happy to act as a witness for its being committed to an insane asylum. (Although I have nothing against saturating arithmetic or signals in some cases, these things really should not be the default when compiling an operating-system kernel.) Signed-off-by: Paul E.
