2007-05-12[POWERPC] Add arch/powerpc support for the Motorola PrPMC2800Dale Farnsworth

2007-05-12[POWERPC] Add bootwrapper support for Motorola PrPMC2800 platformMark A. Greer
The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or PrPMC2800 baseboard, respectively. There are several variants of each type of processor module which can have different amounts of memory, amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362. The bootwrapper code for that platform reads VPD from an I2C EEPROM to determine the processor module variant. From the variant, the amount of memory, etc. is determined and the device tree is updated accordingly. If the variant cannot be determined (e.g., corrupted VPD or a previously unknown variant), the property values already in the device tree are used. Also, the firmware for those platforms does not completely configure the mv64x60 host bridge so that configuration is done here. Signed-off-by: Mark A.

2007-05-12[POWERPC] Add DTS file for the Motorola PrPMC2800 platformMark A. Greer
Add the device tree source file for the prpmc2800 line of processor PMCs. Several of the property values are updated by the bootwrapper but sane defaults have been chosen in case the bootwrapper can't determine the exact processor board variant. The defaults should allow the kernel to boot despite having non-optimal device tree property values. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-05-12[POWERPC] Add interrupt support for Marvell mv64x60 chipsDale Farnsworth
There are 3 interrupt groups each with its own status/mask registers. We use a separate struct irq_chip for each interrupt group and handle interrupts in two stages or levels: level 1 selects the appropriate struct irq_chip, and level 2 selects individual interrupts within that irq_chip.

2007-05-12[POWERPC] Add bootwrapper support for Marvell/mv64x60 I2CMark A. Greer
Some platforms support a variety processor modules with no method of determining which exact processor module is being used except by examining Vital Product Data (VPD). The modules may have different amounts of memory, clock frequencies, etc. so reading the VPD becomes necessary to correctly set properties in the device tree before its passed to the kernel. Often the VPD is stored in I2C EEPROMs so an I2C driver becomes necessary. This I2C driver is for the I2C controller that's embedded on the Marvel mv64x60 line of host bridges. Signed-off-by: Mark A.

2007-05-12[POWERPC] Add bootwrapper support for Marvell MPSCMark A. Greer

2007-05-12[POWERPC] Add bootwrapper support for Marvell/mv64x60 hostbridgeMark A. Greer
The mv64x60 host bridge has many windows between its various components (cpu, system memory, ethernet ctlr, MPSC, DMA ctlr, PCI MEM, PCI I/O). Unfortunately, the firmware on some of mv64x60-based platforms do not properly or completely configure those windows (e.g., MPSC->system memory windows not configured or CPU->PCI MEM space not configured). So, the missing configuration needs to be done in either the bootwrapper or in the kernel. To keep the kernel as clean as possible, it is done in the bootwrapper. Note that I/O controller configuration is NOT being done, its only the windows to allow the I/O controllers and other components to access memory, etc. that is being done--drivers assume that their controllers can already access system memory). Table of routines and the windows they configure: mv64x60_config_ctlr_windows() ENET->System Memory MPSC->System Memory IDMA->System Memory mv64x60_config_pci_windows() PCI MEM->System Memory PCI I/O->Bridge's Registers mv64x60_config_cpu2pci_window() CPU->PCI MEM CPU->PCI I/O Signed-off-by: Mark A.

2007-05-12[POWERPC] Add Makefile rules to wrap dts file in zImageMark A. Greer
Add 'zImage.dts' and 'zImage.dts_initrd' build rules that automatically compile and wrap a dts file from arch/powerpc/boot/dts into the zImage file. The resulting zImage will be arch/powerpc/boot/zImage.dts.<platform> and arch/powerpc/boot/zImage.dts_initrd.<platform>, respectively. Having separate rules allows the user to choose whether to include a device tree--and which device tree--at build time. This is useful when one Makefile target builds a zImage that runs on several platforms except for differing device trees. By just setting CONFIG_DEVICE_TREE and running "make zImage.dts" the exact zImage you want is built without Makefile bloat or manually running the wrapper script. The dts file is expected to be arch/powerpc/boot/dts/$(CONFIG_DEVICE_TREE) Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-05-12[POWERPC] Simplify smp_space_timerswill schmidt
Greatly simplify the function smp_space_timers. The stolen time calculation (per comment within the code) doesn't need the half-jiffy stagger any more. There isn't an issue with bouncing off global locks, so we really shouldn't need any sort of staggering at all. However, the last_jiffy value still needs to be set. This removes the extra stagger logic, and just sets the values. This change should benefit applications that rely on barrier synchronization, and will help cut down OS jitter.

2007-05-11powerpc: fixup hard_irq_disable semanticsBenjamin Herrenschmidt
This patch renames the raw hard_irq_{enable,disable} into __hard_irq_{enable,disable} and introduces a higher level hard_irq_disable() function that can be used by any code to enforce that IRQs are fully disabled, not only lazy disabled. The difference with the __ versions is that it will update some per-processor fields so that the kernel keeps track and properly re-enables them in the next local_irq_disable(); This prepares powerpc for my next patch that introduces hard_irq_disable() generically.

2007-05-11[PATCH] audit signal recipientsAmy Griffis
When auditing syscalls that send signals, log the pid and security context for each target process. Optimize the data collection by adding a counter for signal-related rules, and avoiding allocating an aux struct unless we have more than one target process. For process groups, collect pid/context data in blocks of 16. Move the audit_signal_info() hook up in check_kill_permission() so we audit attempts where permission is denied.

2007-05-10[POWERPC] Fix incorrect calculation of I/O window addressesPaul Mackerras
My patch "Cope with PCI host bridge I/O window not starting at 0" introduced a bug in the calculation of the virtual addresses for the I/O windows of PCI host bridges other than the first, because it didn't account for the fact that hose->io_resource gets offset so that it reflects the range of global I/O port numbers assigned to the bridge.

2007-05-09[POWERPC] Change rheap functions to use ulongs instead of pointersTimur Tabi
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().

2007-05-09rename thread_info to stackRoman Zippel
This finally renames the thread_info field in task structure to stack, so that the assumptions about this field are gone and archs have more freedom about placing the thread_info structure. Nonbroken archs which have a proper thread pointer can do the access to both current thread and task structure via a single pointer. It'll allow for a few more cleanups of the fork code, from which e.g. ia64 could benefit.

2007-05-09Add suspend-related notifications for CPU hotplugRafael J. Wysocki
Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).
