* 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.

* kprobes: support kretprobe blacklistMasami Hiramatsu2007-10-161-0/+2
| | | | | | | | | | | | | | | | | Introduce architecture dependent kretprobe blacklists to prohibit users from inserting return probes on the function in which kprobes can be inserted but kretprobes can not. This patch also removes "__kprobes" mark from "__switch_to" on x86_64 and registers "__switch_to" to the blacklist on x86-64, because that mark is to prohibit user from inserting only kretprobe.

* [AVR32] Fix random segfault with preemptionPhilippe Rétornaz2007-10-111-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | As explained on: http://www.avrfreaks.net/index.php?nameÿphpBB2&fileÿewtopic&tS307 If the current process is preempted before it can copy RAR_SUP and RSR_SUP both register are lost and the process will segfault as soon as it return from the syscall since the return adress will be corrupted. This patch disable IRQ as soon as we enter the syscall path and reenable them when the copy is done. In the interrupt handlers, check if we are interrupting the srrf instruction, if so disable interrupts and return. The interrupt handler will be re-called immediatly when the interrupts are reenabled. After some stressing workload: - find / > /dev/null in loop - top (in ssh) - ping -f avr32 The segfaults are not seen anymore.

* [AVR32] Remove unneeded 8K alignment of .text sectionHaavard Skinnemoen2007-10-111-1/+0
| | | | | | | | | | | | | | __init_end, which comes immediately before .text, is already page aligned, and that should be more than enough for the .text section. The reason why we need to align the .text section is because the interrupt handler offset is ORed with EVBA, so we need to provide enough alignment of EVBA that this OR operation works as an ADD. Currently, the last interrupt handler is not nearly a full page away from EVBA, so it won't be a problem. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

* generic bug: use show_regs() instead of dump_stack()Heiko Carstens2007-07-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current generic bug implementation has a call to dump_stack() in case a WARN_ON(whatever) gets hit. Since report_bug(), which calls dump_stack(), gets called from an exception handler we can do better: just pass the pt_regs structure to report_bug() and pass it to show_regs() in case of a warning. This will give more debug informations like register contents, etc... In addition this avoids some pointless lines that dump_stack() emits, since it includes a stack backtrace of the exception handler which is of no interest in case of a warning. E.g. on s390 the following lines are currently always present in a stack backtrace if dump_stack() gets called from report_bug(): [<000000000001517a>] show_trace+0x92/0xe8) [<0000000000015270>] show_stack+0xa0/0xd0 [<00000000000152ce>] dump_stack+0x2e/0x3c [<0000000000195450>] report_bug+0x98/0xf8 [<0000000000016cc8>] illegal_op+0x1fc/0x21c [<00000000000227d6>] sysc_return+0x0/0x10 Acked-by: Jeremy Fitzhardinge <jeremy@goop.org> Acked-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Cc: Andi Kleen <ak@suse.de> Cc: Kyle McMartin <kyle@parisc-linux.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Paul Mundt <lethal@linux-sh.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* move die notifier handling to common codeChristoph Hellwig2007-05-083-17/+3
| | | | | | | | | | | | | | | | | | | | | | | This patch moves the die notifier handling to common code. Previous various architectures had exactly the same code for it. Note that the new code is compiled unconditionally, this should be understood as an appel to the other architecture maintainer to implement support for it aswell (aka sprinkling a notify_die or two in the proper place) arm had a notifiy_die that did something totally different, I renamed it to arm_notify_die as part of the patch and made it static to the file it's declared and used at. avr32 used to pass slightly less information through this interface and I brought it into line with the other architectures.

| | | | | | | | | | | | | | With the current strategy of using the bootmem allocator to allocate or reserve framebuffer memory, there's a slight chance that the requested area has been taken by the boot allocator bitmap before we get around to reserving it. By inserting the framebuffer region as a reserved region as early as possible, we improve our chances for success and we make the region visible as a reserved region in dmesg and /proc/iomem without any extra work.
