parisc uses iova and iova_length in scatterlist structure instead of dma_address and dma_length. However, the accessor are used so we can convert parisc to use asm-generic/scatterlist.h easily.

This is the first half of the attempt to use asm-generic/scatterlist.h on every architecture. There are only two ways to define scatterlist structure. So it's easy to convert every architecture to use asm-generic/scatterlist.h. This patch: The trick for ISA_DMA_THRESHOLD in asm-generic/scatterlist.h doesn't work for powerpc.

2010-05-27rapidio: fix maintenance access to higher memory areasThomas Moll1-7/+30
Fix the maintenance access functions to farend RapidIO devices. 1. Fixed shift of the given offset, to open the maintenance window 2. Mask offset to limit access to the opened maintenance window 3. Added extended destid part to rowtear register, required for 16bit mode This method is matching maintenance transactions generation described by Freescale in the appnote AN2932. With this modification full access to a 16MB maintenance window is possible, this patch is required for IDT cps switches. For easier handling of the access routines, the access was limited to aligned memory regions. This should be no problem because all registers are 32bit wide.

But we are going to make ->signal refcountable, change the code to use ->sighand. Note: this code doesn't need this check and tasklist_lock at all, it should be converted to use lock_task_sighand().

Some workloads that create a large number of small files tend to assign too many pages to node 0 (multi-node systems). Part of the reason is that the rotor (in cpuset_mem_spread_node()) used to assign nodes starts at node 0 for newly created tasks.

2010-05-27davinci: mmc: pass number of SG segments as platform dataSudhakar Rajashekhara1-0/+3
On some platforms like DM355, the number of EDMA parameter slots available for EDMA_SLOT_ANY usage are few. In such cases, if MMC/SD uses 16 slots for each instance of MMC controller, then the number of slots available for other modules will be very few. By passing the number of EDMA slots to be used in MMC driver from platform data, EDMA slots available for other purposes can be controlled. Most of the platforms will not use this platform data variable. But on DM355, as the number of EDMA resources available is limited, the number of scatter- gather segments used inside the MMC driver can be 8 (passed as platform data) instead of 16. On DM355, when the number of scatter-gather segments was reduced to 8, I saw a performance difference of about 0.25-0.4 Mbytes/sec during write. Read performance variations were negligible.

2010-05-25driver core: add devname module aliases to allow module on-demand auto-loadingKay Sievers1-0/+1
This adds: alias: devname:<name> to some common kernel modules, which will allow the on-demand loading of the kernel module when the device node is accessed. Ideally all these modules would be compiled-in, but distros seems too much in love with their modularization that we need to cover the common cases with this new facility. It will allow us to remove a bunch of pretty useless init scripts and modprobes from init scripts. The static device node aliases will be carried in the module itself. The program depmod will extract this information to a file in the module directory: $ cat /lib/modules/2.6.34-00650-g537b60d-dirty/modules.devname # Device nodes to trigger on-demand module loading. microcode cpu/microcode c10:184 fuse fuse c10:229 ppp_generic ppp c108:0 tun net/tun c10:200 dm_mod mapper/control c10:235 Udev will pick up the depmod created file on startup and create all the static device nodes which the kernel modules specify, so that these modules get automatically loaded when the device node is accessed: $ /sbin/udevd --debug ... static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184 static_dev_create_from_modules: mknod '/dev/fuse' c10:229 static_dev_create_from_modules: mknod '/dev/ppp' c108:0 static_dev_create_from_modules: mknod '/dev/net/tun' c10:200 static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235 udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666 udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666 A few device nodes are switched to statically allocated numbers, to allow the static nodes to work. This might also useful for systems which still run a plain static /dev, which is completely unsafe to use with any dynamic minor numbers. Note: The devname aliases must be limited to the *common* and *single*instance* device nodes, like the misc devices, and never be used for conceptually limited systems like the loop devices, which should rather get fixed properly and get a control node for losetup to talk to, instead of creating a random number of device nodes in advance, regardless if they are ever used. This facility is to hide the mess distros are creating with too modualized kernels, and just to hide that these modules are not compiled-in, and not to paper-over broken concepts.

2010-05-25endian: #define __BYTE_ORDERJoakim Tjernlund7-31/+2
Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.

Extend gdbstub to support more features of gdb remote protocol to keep gdb-7 and emacs gud mode happy: (*) The D command. Detach debugger. (*) The H command. Handle setting the target thread by ignoring it. (*) The qAttached command. Indicate we 'attached' to an existing process. (*) The qC command. Indicate that the current thread ID is 0. (*) The qOffsets command. Indicate that no relocation has been done. (*) The qSymbol:: command. Indicate that we're not interested in looking up any symbol addresses. (*) The qSupported command. Indicate the maximum packet size and the fact that reverse step and continue aren't supported. (*) The vCont? command. Indicate that we don't support any of its variants. Also make it possible to trace the commands and replies without tracing the individual character I/O.
