| | | | | | | | | | | | | | | | | | | | | | The BCM148 has 4 cores but there are also just 4 generic timers available so use the ZBbus cycle counter instead of it. In addition the ZBbus counter also offers a much higher resolution and 64-bit counting so I'm considering a later complete conversion to it once I figure out if all members of the Sibyte SOC family support it - the docs seem to agree but the headers files seem to disagree ...

* | pid namespaces: define is_global_init() and is_container_init()Serge E. Hallyn2007-10-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | pid namespaces: round up the APIPavel Emelianov2007-10-193-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The set of functions process_session, task_session, process_group and task_pgrp is confusing, as the names can be mixed with each other when looking at the code for a long time. The proposals are to * equip the functions that return the integer with _nr suffix to represent that fact, * and to make all functions work with task (not process) by making the common prefix of the same name. For monotony the routines signal_session() and set_signal_session() are replaced with task_session_nr() and set_task_session(), especially since they are only used with the explicit task->signal dereference.

* [MIPS] SYNC emulation for MIPS I processorsMaciej W. Rozycki2007-10-171-78/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Userland, including the C library and the dynamic linker, is keen to use the SYNC instruction, even for "generic" MIPS I binaries these days. Which makes it less than useful on MIPS I processors. This change adds the emulation, but as our do_ri() infrastructure was not really prepared to take yet another instruction, I have rewritten it and its callees slightly as follows. Now there is only a single place a possible signal is thrown from. The place is at the end of do_ri(). The instruction word is fetched in do_ri() and passed down to handlers. The handlers are called in sequence and return a result that lets the caller decide upon further processing. If the result is positive, then the handler has picked the instruction, but a signal should be thrown and the result is the signal number. If the result is zero, then the handler has successfully simulated the instruction. If the result is negative, then the handler did not handle the instruction; to make it more obvious the calls do not follow the usual 0/-Exxx result convention they now return -1 instead of -EFAULT. The calculation of the return EPC is now at the beginning. The reason is it is easier to handle it there as emulation callees may modify a register and an instruction may be located in delay slot of a branch whose result depends on the register. It has to be undone if a signal is to be raised, but it is not a problem as this is the slow-path case, and both actions are done in single places now rather than the former being scattered through emulation handlers. The part of do_cpu() being covered follows the changes to do_ri(). Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> ---

A modern replacement is available as drivers/input/keyboard/lkkbd.c. There are no plans to do anything about this piece of code and it does not fit anywhere anymore, so it is not just a matter of maintenance or the lack of. There are still some bits that might be added to the new lkkbd.c driver based on the old code, and the embedded hardware documentation which is otherwise quite hard to get hold of might be useful to keep too.

| | | | | | | | | | | | | | | | | | | | 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.

* core_pattern: ignore RLIMIT_CORE if core_pattern is a pipeNeil Horman2007-10-171-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some time /proc/sys/kernel/core_pattern has been able to set its output destination as a pipe, allowing a user space helper to receive and intellegently process a core. This infrastructure however has some shortcommings which can be enhanced. Specifically: 1) The coredump code in the kernel should ignore RLIMIT_CORE limitation when core_pattern is a pipe, since file system resources are not being consumed in this case, unless the user application wishes to save the core, at which point the app is restricted by usual file system limits and restrictions. 2) The core_pattern code should be able to parse and pass options to the user space helper as an argv array. The real core limit of the uid of the crashing proces should also be passable to the user space helper (since it is overridden to zero when called). 3) Some miscellaneous bugs need to be cleaned up (specifically the recognition of a recursive core dump, should the user mode helper itself crash. Also, the core dump code in the kernel should not wait for the user mode helper to exit, since the same context is responsible for writing to the pipe, and a read of the pipe by the user mode helper will result in a deadlock. This patch: Remove the check of RLIMIT_CORE if core_pattern is a pipe. In the event that core_pattern is a pipe, the entire core will be fed to the user mode helper.

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.
