2006-02-27[MIPS] SMP: Fix initialization order bug.Ralf Baechle3-7/+11
A recent change requires cpu_possible_map to be initialized before smp_sched_init() but most MIPS platforms were initializing their processors in the prom_prepare_cpus callback of smp_prepare_cpus. The simple fix of calling prom_prepare_cpus from one of the earlier SMP initialization hooks doesn't work well either since IPIs may require init_IRQ() to have completed, so bit the bullet and split prom_prepare_cpus into two initialization functions, plat_smp_setup which is called early from setup_arch and plat_prepare_cpus called where prom_prepare_cpus used to be called.

2006-02-24[PATCH] flags parameter for linkatUlrich Drepper1-1/+1
I'm currently at the POSIX meeting and one thing covered was the incompatibility of Linux's link() with the POSIX definition. The name. Linux does not follow symlinks, POSIX requires it does. Even if somebody thinks this is a good default behavior we cannot change this because it would break the ABI. But the fact remains that some application might want this behavior. We have one chance to help implementing this without breaking the behavior. For this we could use the new linkat interface which would need a new flags parameter. If the new parameter is AT_SYMLINK_FOLLOW the new behavior could be invoked. I do not want to introduce such a patch now. But we could add the parameter now, just don't use it. The patch below would do this. Can we get this late patch applied before the release more or less fixes the syscall API?

2006-02-21[MIPS] Add topology_init.Rojhalat Ibrahim1-0/+20
A recent patch introduced cpu topology in sysfs. When you run a kernel with SMP and sysfs enabled, you now get an Oops on boot. The following patch fixes that by adding topology_init to arch/mips/kernel/smp.c. The code is copied from arch/s390/kernel/smp.c.

2006-02-14[MIPS] Rewrite get_wchan and its helper functions using kallsyms_lookup.Atsushi Nemoto1-81/+77
Implement get_wchan() and frame_info_init() using kallsyms_lookup(). This fixes problem with static sched/lock functions and mfinfo[] maintenance issue. If CONFIG_KALLSYMS was disabled, get_wchan() just returns thread_saved_pc() value. Also unwind stackframe based on "addiu sp,-imm" analysis instead of frame pointer.

2006-01-10[PATCH] sanitize building of fs/compat_ioctl.cChristoph Hellwig2-52/+1
Now that all these entries in the arch ioctl32.c files are gone [1], we can build fs/compat_ioctl.c as a normal object and kill tons of cruft. We need a special do_ioctl32_pointer handler for s390 so the compat_ptr call is done. This is not needed but harmless on all other architectures. Also remove some superflous includes in fs/compat_ioctl.c Tested on ppc64. [1] parisc still had it's PPP handler left, which is not fully correct for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd kick in for all netdevice users. We can introduce a proper handler in one of the next patch series by adding a compat_ioctl method to struct net_device but for now let's just kill it - parisc doesn't compile in mainline anyway and I don't want this to block this patchset.

2006-01-08[PATCH] use ptrace_get_task_struct in various placesChristoph Hellwig1-20/+6
The ptrace_get_task_struct() helper that I added as part of the ptrace consolidation is useful in variety of places that currently opencode it. Switch them to the common helpers. Add a ptrace_traceme() helper that needs to be explicitly called, and simplify the ptrace_get_task_struct() interface. We don't need the request argument now, and we return the task_struct directly, using ERR_PTR() for error returns. It's a bit more code in the callers, but we have two sane routines that do one thing well now.

2006-01-04Relax the rw_verify_area() error checking.Linus Torvalds1-2/+2
In particular, allow over-large read- or write-requests to be downgraded to a more reasonable range, rather than considering them outright errors. We want to protect lower layers from (the sadly all too common) overflow conditions, but prefer to do so by chopping the requests up, rather than just refusing them outright.
