* Combine instrumentation menus in kernel/Kconfig.instrumentationMathieu Desnoyers2007-10-19
| | | | | | | | | | | | | | | | | 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.

| * 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

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.

* define new percpu interface for shared dataFenghua Yu2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | per cpu data section contains two types of data. One set which is exclusively accessed by the local cpu and the other set which is per cpu, but also shared by remote cpus. In the current kernel, these two sets are not clearely separated out. This can potentially cause the same data cacheline shared between the two sets of data, which will result in unnecessary bouncing of the cacheline between cpus. One way to fix the problem is to cacheline align the remotely accessed per cpu data, both at the beginning and at the end. Because of the padding at both ends, this will likely cause some memory wastage and also the interface to achieve this is not clean. This patch: Moves the remotely accessed per cpu data (which is currently marked as ____cacheline_aligned_in_smp) into a different section, where all the data elements are cacheline aligned. And as such, this differentiates the local only data and remotely accessed data cleanly.

* ALPHA: support graphics on non-zero PCI domainsJay Estabrook2007-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code replaces earlier and incomplete handling of graphics on non-zero PCI domains (aka hoses or peer PCI buses). An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose SRM consoles are capable of configuring and handling graphics options on non-zero hoses. All other machines have the option set FALSE. A routine, "find_console_vga_hose()", is used to find the graphics device which the machine's firmware believes is the console device, and it sets a global (pci_vga_hose) for later use in managing access to the device. This is called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a custom version of this routine because of extra complexity. A routine, "locate_and_init_vga()", is used to find the graphics device and set a global (pci_vga_hose) for later use in managing access to the device, in the case where "find_console_vga_hose" has failed. Various adjustments are made to the ioremap and ioportmap routines for detecting and translating "legacy" VGA register and memory references to the real PCI domain.

Additionally the sys_utime function was changed to match compat_sys_utime which already use do_utimes instead of duplicating the work. Also, the completely missing futimensat() functionality is added. We have such a function in glibc but we have to resort to using /proc/self/fd/* which not everybody likes (chroot etc).

* Fixes and cleanups for earlyprintk aka boot consoleGerd Hoffmann2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The console subsystem already has an idea of a boot console, using the CON_BOOT flag. The implementation has some flaws though. The major problem is that presence of a boot console makes register_console() ignore any other console devices (unless explicitly specified on the kernel command line). This patch fixes the console selection code to *not* consider a boot console a full-featured one, so the first non-boot console registering will become the default console instead. This way the unregister call for the boot console in the register_console() function actually triggers and the handover from the boot console to the real console device works smoothly. Added a printk for the handover, so you know which console device the output goes to when the boot console stops printing messages. The disable_early_printk() call is obsolete with that patch, explicitly disabling the early console isn't needed any more as it works automagically with that patch. I've walked through the tree, dropped all disable_early_printk() instances found below arch/ and tagged the consoles with CON_BOOT if needed. The code is tested on x86, sh (thanks to Paul) and mips (thanks to Ralf). Changes to last version: Rediffed against -rc3, adapted to mips cleanups by Ralf, fixed "udbg-immortal" cmd line arg on powerpc.
