2008-07-25locking: add typecheck on irqsave and friends for correct flagsSteven Rostedt
There haave been several areas in the kernel where an int has been used for flags in local_irq_save() and friends instead of a long. This can cause some hard to debug problems on some architectures. This patch adds a typecheck inside the irqsave and restore functions to flag these cases.

2008-07-25endian: Always evaluate arguments.David Miller
Changeset 7fa897b91a3ea0f16c2873b869d7a0eef05acff4 ("ide: trivial sparse annotations") created an IDE bootup regression on big-endian systems. In drivers/ide/ide-iops.c, function ide_fixstring() we now have the loop: for (p = end ; p != s;) be16_to_cpus((u16 *)(p -= 2)); which will never terminate on big-endian because in such a configuration be16_to_cpus() evaluates to "do { } while (0)" Therefore, always evaluate the arguments to nop endian transformation operations.

2008-07-25[MTD] [NAND] subpage read feature as a way to increase performance. Alexey Korolev
This patch enables NAND subpage read functionality. If upper layer drivers are requesting to read non page aligned data NAND subpage-read functionality reads the only whose ECC regions which include requested data when original code reads whole page. This significantly improves performance in many cases.

2008-07-25firewire: fw-ohci: TSB43AB22/A dualbuffer workaroundStefan Richter
Isochronous reception in dualbuffer mode is reportedly broken with TI TSB43AB22A on x86-64. Descriptor addresses above 2G have been determined as the trigger: https://bugzilla.redhat.com/show_bug.cgi?id=435550 Two fixes are possible: - pci_set_consistent_dma_mask(pdev, DMA_31BIT_MASK); at least when IR descriptors are allocated, or - simply don't use dualbuffer. This fix implements the latter workaround. But we keep using dualbuffer on x86-32 which won't give us highmen (and thus physical addresses outside the 31bit range) in coherent DMA memory allocations. Right now we could for example also whitelist PPC32, but DMA mapping implementation details are expected to change there.

2008-07-25powerpc/pseries: vio bus support for CMORobert Jennings
This is a large patch but the normal code path is not affected. For non-pSeries platforms the code is ifdef'ed out and for non-CMO enabled pSeries systems this does not affect the normal code path. Devices that do not perform DMA operations do not need modification with this patch. The function get_desired_dma was renamed from get_io_entitlement for clarity. Overview Cooperative Memory Overcommitment (CMO) allows for a set of OS partitions to be run with less RAM than the aggregate needs of the group of partitions. The firmware will balance memory between the partitions and page in/out memory as needed. Based on the number and type of IO adpaters preset each partition is allocated an amount of memory for DMA operations and this allocation will be guaranteed to the partition; this is referred to as the partition's 'entitlement'. Partitions running in a CMO environment can only have virtual IO devices present. The VIO bus layer will manage the IO entitlement for the system. Accounting, at a system and per-device level, is tracked in the VIO bus code and exposed via sysfs. A set of dma_ops functions are added to the bus to allow for this accounting. Bus initialization At initialization, the bus will calculate the minimum needs of the system based on providing each device present with a standard minimum entitlement along with a spare allocation for the bus to handle hotplug events. If the minimum needs can not be met the system boot will be halted. Device changes The significant changes for devices while running under CMO are that the devices must specify how much dedicated IO entitlement they desire and must also handle DMA mapping errors that can occur due to constrained IO memory. The virtual IO drivers are modified to silence errors when DMA mappings fail for CMO and handle these failures gracefully. Each devices will be guaranteed a minimum entitlement that can always be mapped. Devices will specify how much entitlement they desire and the VIO bus will attempt to provide for this. Devices can change their desired entitlement level at any point in time to address particular needs (via vio_cmo_set_dev_desired()), not just at device probe time. VIO bus changes The system will have a particular entitlement level available from which it can provide memory to the devices. The bus defines two pools of memory within this entitlement, the reserved and excess pools. Each device is provided with it's own entitlement no less than a system defined minimum entitlement and no greater than what the device has specified as it's desired entitlement. The entitlement provided to devices comes from the reserve pool. The reserve pool can also contain a spare allocation as large as the system defined minimum entitlement which is used for device hotplug events. Any entitlement not needed to fulfill the needs of a reserve pool is placed in the excess pool. Each device is guaranteed that it can map up to it's entitled level; additional mapping are possible as long as there is unmapped memory in the excess pool. Bus probe As the system starts, each device is given an entitlement equal only to the system defined minimum entitlement. The reserve pool is equal to the sum of these entitlements, plus a spare allocation. The VIO bus also tracks the aggregate desired entitlement of all the devices. If the system desired entitlement is greater than the size of the reserve pool, when devices unmap IO memory it will be reserved and a balance operation will be scheduled for some time in the future. Entitlement balancing The balance function tries to fairly distribute entitlement between the devices in the system with the goal of providing each device with it's desired amount of entitlement. Devices using more than what would be ideal will have their entitled set-point adjusted; this will effectively set a goal for lower IO memory usage as future mappings can fail and deallocations will trigger a balance operation to distribute the newly unmapped memory. A fair distribution of entitlement can take several balance operations to achieve. Entitlement changes and device DLPAR events will alter the state of CMO and will trigger balance operations. Hotplug events The VIO bus allows for changes in system entitlement at run-time via 'vio_cmo_entitlement_update()'. When devices are added the hotplug device event will be preceded by a system entitlement increase and this is reversed when devices are removed. The following changes are made that the VIO bus layer for CMO: * add IO memory accounting per device structure. * add IO memory entitlement query function to driver structure. * during vio bus probe, if CMO is enabled, check that driver has memory entitlement query function defined. Fail if function not defined. * fail to register driver if io entitlement function not defined. * create set of dma_ops at vio level for CMO that will track allocations and return DMA failures once entitlement is reached. Entitlement will limited by overall system entitlement. Devices will have a reserved quantity of memory that is guaranteed, the rest can be used as available. * expose entitlement, current allocation, desired allocation, and the allocation error counter for devices to the user through sysfs * provide mechanism for changing a device's desired entitlement at run time for devices as an exported function and sysfs tunable * track any DMA failures for entitled IO memory for each vio device. * check entitlement against available system entitlement on device add * track entitlement metrics (high water mark, current usage) * provide function to reset high water mark * provide minimum and desired entitlement numbers at a bus level * provide drivers with a minimum guaranteed entitlement * balance available entitlement between devices to satisfy their needs * handle system entitlement changes and device hotplug Signed-off-by: Robert Jennings <rcj@linux.vnet.ibm.com> Acked-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2008-07-25powerpc/pseries: iommu enablement for CMORobert Jennings
To support Cooperative Memory Overcommitment (CMO), we need to check for failure from some of the tce hcalls. These changes for the pseries platform affect the powerpc architecture; patches for the other affected platforms are included in this patch. pSeries platform IOMMU code changes: * platform TCE functions must handle H_NOT_ENOUGH_RESOURCES errors and return an error. Architecture IOMMU code changes: * Calls to ppc_md.tce_build need to check return values and return DMA_MAPPING_ERROR for transient errors. Architecture changes: * struct machdep_calls for tce_build*_pSeriesLP functions need to change to indicate failure. * all other platforms will need updates to iommu functions to match the new calling semantics; they will return 0 on success. The other platforms default configs have been built, but no further testing was performed.

2008-07-25ELF loader support for auxvec base platform stringNathan Lynch
Some IBM POWER-based platforms have the ability to run in a mode which mostly appears to the OS as a different processor from the actual hardware. For example, a Power6 system may appear to be a Power5+, which makes the AT_PLATFORM value "power5+". This means that programs are restricted to the ISA supported by Power5+; Power6-specific instructions are treated as illegal. However, some applications (virtual machines, optimized libraries) can benefit from knowledge of the underlying CPU model. A new aux vector entry, AT_BASE_PLATFORM, will denote the actual hardware. For example, on a Power6 system in Power5+ compatibility mode, AT_PLATFORM will be "power5+" and AT_BASE_PLATFORM will be "power6". The idea is that AT_PLATFORM indicates the instruction set supported, while AT_BASE_PLATFORM indicates the underlying microarchitecture. If the architecture has defined ELF_BASE_PLATFORM, copy that value to the user stack in the same manner as ELF_PLATFORM.

2008-07-24x86-64: Clean up 'save/restore_i387()' usageLinus Torvalds
Suresh Siddha wants to fix a possible FPU leakage in error conditions, but the fact that save/restore_i387() are inlines in a header file makes that harder to do than necessary. So start off with an obvious cleanup. This just moves the x86-64 version of save/restore_i387() out of the header file, and moves it to the only file that it is actually used in: arch/x86/kernel/signal_64.c. So exposing it in a header file was wrong to begin with. [ Side note: I'd like to fix up some of the games we play with the 32-bit version of these functions too, but that's a separate matter. The 32-bit versions are shared - under different names at that! - by both the native x86-32 code and the x86-64 32-bit compatibility code ] Acked-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
