| | | | | | | | | | | | | | | | | Quoting Randy: "It seems sad that this patch sources Kconfig.marker, a 7-line file, 20-something times. Yes, you (we) don't want to put those 7 lines into 20-something different files, so sourcing is the right thing. However, what you did for avr32 seems more on the right track to me: make _one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES, and MARKERS and then use (source) that in all of the arches."

* Use helpers to obtain task pid in printks (arch code)Alexey Dobriyan2007-10-19
| | | | | | | | | | | | | | | One of the easiest things to isolate is the pid printed in kernel log. There was a patch, that made this for arch-independent code, this one makes so for arch/xxx files. It took some time to cross-compile it, but hopefully these are all the printks in arch code.

* pid namespaces: define is_global_init() and is_container_init()Serge E. Hallyn2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is_init() is an ambiguous name for the pid==1 check. Split it into is_global_init() and is_container_init(). A cgroup init has it's tsk->pid == 1. A global init also has it's tsk->pid == 1 and it's active pid namespace is the init_pid_ns. But rather than check the active pid namespace, compare the task structure with 'init_pid_ns.child_reaper', which is initialized during boot to the /sbin/init process and never changes. Changelog: 2.6.22-rc4-mm2-pidns1: - Use 'init_pid_ns.child_reaper' to determine if a given task is the global init (/sbin/init) process. This would improve performance and remove dependence on the task_pid(). 2.6.21-mm2-pidns2: - [Sukadev Bhattiprolu] Changed is_container_init() calls in {powerpc, ppc,avr32}/traps.c for the _exception() call to is_global_init(). This way, we kill only the cgroup if the cgroup's init has a bug rather than force a kernel panic.

* Remove dma_cache_(wback|inv|wback_inv) functionsRalf Baechle2007-10-17
| | | | | | | | | | | | | | | | | | | | dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized cache managment API for I/O purposes. Originally it was basically the raw MIPS low level cache API exported to the entire world. The API has suffered from a lack of documentation, was not very widely used unlike it's more modern brothers and can easily be replaced by dma_cache_sync. So remove it rsp. turn the surviving bits back into an arch private API, as discussed on linux-arch.

| * kbuild: enable 'make CFLAGS=...' to add additional options to CCSam Ravnborg2007-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

* | During VM oom condition, kill all threads in process groupWill Schmidt2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have had complaints where a threaded application is left in a bad state after one of it's threads is killed when we hit a VM: out_of_memory condition. Killing just one of the process threads can leave the application in a bad state, whereas killing the entire process group would allow for the application to restart, or be otherwise handled, and makes it very obvious that something has gone wrong. This change allows the entire process group to be taken down, rather than just the one thread.
