All architectures have CONFIG_GENERIC_KERNEL_THREAD CONFIG_GENERIC_KERNEL_EXECVE __ARCH_WANT_SYS_EXECVE None of them have __ARCH_WANT_KERNEL_EXECVE and there are only two callers of kernel_execve() (which is a trivial wrapper for do_execve() now) left. Kill the conditionals and make both callers use do_execve(). Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela, ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version into asm-generic/module.h for all arches bar MIPS. Also, use the generic definition mod_arch_specific where possible. To this end, I've defined three new config bools: (*) HAVE_MOD_ARCH_SPECIFIC Arches define this if they don't want to use the empty generic mod_arch_specific struct. (*) MODULES_USE_ELF_RELA Arches define this if their modules can contain RELA records. This causes the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be defined by the arch rather than have the core emit an error message. (*) MODULES_USE_ELF_REL Arches define this if their modules can contain REL records. This causes the Elf_Rel mapping to be emitted and allows apply_relocate() to be defined by the arch rather than have the core emit an error message. Note that it is possible to allow both REL and RELA records: m68k and mips are two arches that do this. With this, some arch asm/module.h files can be deleted entirely and replaced with a generic-y marker in the arch Kbuild file. Additionally, I have removed the bits from m32r and score that handle the unsupported type of relocation record as that's now handled centrally.

Sigh, I missed to check which architecture Kconfig files actually include the core Kconfig file. There are a few which did not. So we broke them. Instead of adding the includes to those, we are better off to move the include to init/Kconfig like we did already with irqs and others. This does not change anything for the architectures using the old style periodic timer mode. It just solves the build wreckage there. For those architectures which use the clock events infrastructure it moves the include of the core Kconfig file to "General setup" which is a way more logical place than having it at random locations specified by the architecture specific Kconfigs.

Rather than requiring architectures that use gpiolib but don't have any need to define anything custom to copy an asm/gpio.h provide a Kconfig symbol which architectures must select in order to include gpio.h and for other architectures just provide the trivial implementation directly. This makes it much easier to do gpiolib updates and is also a step towards making gpiolib APIs available on every architecture. For architectures with existing boilerplate code leave a stub header in place which warns on direct inclusion of asm/gpio.h and includes linux/gpio.h to catch code that's doing this. Direct inclusion of asm/gpio.h has long been deprecated.

cmpxchg() is widely used by lockless code, including NMI-safe lockless code. But on some architectures, the cmpxchg() implementation is not NMI-safe, on these architectures the lockless code may need a spin_trylock_irqsave() based implementation. This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that NMI-safe lockless code can depend on it or provide different implementation according to it. On many architectures, cmpxchg is only NMI-safe for several specific operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

Impact: cleaner and consistent bootmem wrapping By setting CONFIG_HAVE_ARCH_BOOTMEM_NODE, archs can define arch-specific wrappers for bootmem allocation. However, this is done a bit strangely in that only the high level convenience macros can be changed while lower level, but still exported, interface functions can't be wrapped. This not only is messy but also leads to strange situation where alloc_bootmem() does what the arch wants it to do but the equivalent __alloc_bootmem() call doesn't although they should be able to be used interchangeably. This patch updates bootmem such that archs can override / wrap the backend function - alloc_bootmem_core() instead of the highlevel interface functions to allow simpler and consistent wrapping. Also, HAVE_ARCH_BOOTMEM_NODE is renamed to HAVE_ARCH_BOOTMEM. Signed-off-by: NTejun Heo <tj@kernel.org> Cc: Johannes Weiner <hannes@saeurebad.de>

The Hammerhead platform is built around a AVR32 32-bit microcontroller from Atmel. It offers versatile peripherals, such as ethernet, usb device, usb host etc. The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered Device (PD). Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing. This patch does include the basic support for the fpga device driver, but not the device driver itself.

This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read. The state will remain "FREEZING" until one of these things happens: 1) Userspace cancels the freezing operation by writing "RUNNING" to the freezer.state file 2) Userspace retries the freezing operation by writing "FROZEN" to the freezer.state file (writing "FREEZING" is not legal and returns EIO) 3) The tasks that blocked the cgroup from entering the "FROZEN" state disappear from the cgroup's set of tasks.

This patch lets the user enable support for EVKLCD100 and EVKLCD101 (refered to by EVKLCD10X). By enabling EVKLCD10X support the LCD controller and AC97 controller platform devices are added. The user can also choose between the EVKLCD100 (QVGA display) and the EVKLCD101 (VGA display), this is added to automagically select the correct panel timing and resolution parameters. Enabling support for EVKLCD10X addon board will cripple the MCI platform device a bit since they share two GPIO lines (detect and write-protect). These two lines are disabled when EVKLCD10X is enabled. The default configurations are based upon ATNGW100, but with added AC97C and LCDC driver. Virtual terminal is also enabled by default for EVKLCD10X boards. Verified on hardware with a NGW100 + EVKLCD100/101.

Implement Standby support. In this mode, we'll suspend all drivers, put the SDRAM in self-refresh mode and switch off the HSB bus ("frozen" mode.) Implement Suspend-to-mem support. In this mode, we suspend all drivers, put the SDRAM into self-refresh mode and switch off all internal clocks except the 32 kHz oscillator ("stop" mode.) The lowest-level suspend code runs from a small portion of SRAM allocated at startup time. This gets rid of a small potential race with the SDRAM where we might try to enter self-refresh mode in the middle of an icache burst. We also relocate all interrupt and exception handlers to SRAM during the small window when we enter and exit the low-power modes. We don't need to do any special tricks to start and stop the PLL. The main clock is automatically gated by hardware until the PLL is stable. Signed-off-by: NHaavard Skinnemoen <hskinnemoen@atmel.com>

This combines three patches from David Brownell: * avr32: tclib support * avr32: simplify clocksources * avr32: Turn count/compare into a oneshot clockevent device Register both TC blocks (instead of just the first one) so that the AT32/AT91 tclib code will pick them up (instead of just the avr32-only PIT-style clocksource). Rename the first one and its resources appropriately. More cleanups to the cycle counter clocksource code - Disable all the weak symbol magic; remove the AVR32-only TCB-based clocksource code (source and header). - Mark the __init code properly. - Don't forget to report IRQF_TIMER. - Make the system work properly with this clocksource, by preventing use of the CPU "idle" sleep state in the idle loop when it's used. Package the avr32 count/compare timekeeping support as a oneshot clockevent device, so it supports NO_HZ and high res timers. This means it also supports plugging in other clockevent devices and clocksources.

To allow flexible configuration of IDE introduce HAVE_IDE. All archs except arm, um and s390 unconditionally select it. For arm the actual configuration determine if IDE is supported. This is a step towards introducing drivers/Kconfig for arm.
