* fs_enet: Update for API changesScott Wood2007-10-17
| | | | | | | | | | | | | | | | | | | | This driver was recently broken by several changes for which this driver was not (or was improperly) updated: 1. SET_MODULE_OWNER() was removed. 2. netif_napi_add() was only being called when building with the old CPM binding. 3. The received/budget test was backwards. 4. to_net_dev() was wrong -- the device struct embedded in the net_device struct is not the same as the of_platform device in the private struct. 5. napi_disable/napi_enable was being called even when napi was not being used.

* [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctlsJeff Garzik2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.

* [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device.

* [POWERPC] Change rheap functions to use ulongs instead of pointersTimur Tabi2007-05-10
| | | | | | | | | | | | | | | | | | | | The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining. Untested files are: arch/alpha/kernel/err_common.c arch/alpha/kernel/err_ev6.c arch/alpha/kernel/err_ev7.c arch/ia64/sn/kernel/huberror.c arch/ia64/sn/kernel/xpnet.c arch/m68knommu/kernel/dma.c arch/mips/lib/iomap.c arch/powerpc/platforms/pseries/ras.c arch/ppc/8260_io/enet.c arch/ppc/8260_io/fcc_enet.c arch/ppc/8xx_io/enet.c arch/ppc/syslib/ppc4xx_sgdma.c arch/sh64/mach-cayman/iomap.c arch/xtensa/kernel/xtensa_ksyms.c arch/xtensa/platform-iss/setup.c drivers/i2c/busses/i2c-at91.c drivers/i2c/busses/i2c-mpc.c drivers/media/video/saa711x.c drivers/misc/hdpuftrs/hdpu_cpustate.c drivers/misc/hdpuftrs/hdpu_nexus.c drivers/net/au1000_eth.c drivers/net/fec_8xx/fec_main.c drivers/net/fec_8xx/fec_mii.c drivers/net/fs_enet/fs_enet-main.c drivers/net/fs_enet/mac-fcc.c drivers/net/fs_enet/mac-fec.c drivers/net/fs_enet/mac-scc.c drivers/net/fs_enet/mii-bitbang.c drivers/net/fs_enet/mii-fec.c drivers/net/ibm_emac/ibm_emac_core.c drivers/net/lasi_82596.c drivers/parisc/hppb.c drivers/sbus/sbus.c drivers/video/g364fb.c drivers/video/platinumfb.c drivers/video/stifb.c drivers/video/valkyriefb.c include/asm-arm/arch-ixp4xx/dma.h sound/oss/au1550_ac97.c I would welcome test reports for these files.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

| | * POWERPC: Bring the fs_no calculation to the relevant SoC enumerationVitaly Bordug2006-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fs_no mean used to be fs_enet driver driven, hence it was an enumeration across all the possible fs_enet "users" in the SoC. Now, with QE on the pipeline, and to make DTS descriptions more clear, fs_no features relevant SoC part number, with additional field to describe the SoC type. Another reason for that is now not only fs_enet is going to utilize those stuff. There might be UART, HLDC, and even USB, so to prevent confusion and be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were updated in that concern, as well as the relevant DTS.

| | * POWERPC: overhaul with cpm2_map mechanismVitaly Bordug2006-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | Incorporating the new way of cpm2 immr access, introduced in the previous patch, into CPM2 peripheral devices (fs_enet and cpm_uart). Both ppc and powerpc approved working( real actions taken in powerpc only, ppc just has a wrapper to keep init stuff consistent). Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>

| | | | | | | | | | | | | | | | | | | | | This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
