2010-04-02kgdb: use atomic_inc and atomic_dec instead of atomic_setJason Wessel

2010-04-02kgdb: eliminate kgdb_wait(), all cpus enter the same wayJason Wessel
This is a kgdb architectural change to have all the cpus (master or slave) enter the same function. A cpu that hits an exception (wants to be the master cpu) will call kgdb_handle_exception() from the trap handler and then invoke a kgdb_roundup_cpu() to synchronize the other cpus and bring them into the kgdb_handle_exception() as well. A slave cpu will enter kgdb_handle_exception() from the kgdb_nmicallback() and set the exception state to note that the processor is a slave. Previously the salve cpu would have called kgdb_wait(). This change allows the debug core to change cpus without resuming the system in order to inspect arch specific cpu information. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>

2010-04-02kgdb: have ebin2mem call probe_kernel_write onceJason Wessel
Rather than call probe_kernel_write() one byte at a time, process the whole buffer locally and pass the entire result in one go. This way, architectures that need to do special handling based on the length can do so, or we only end up calling memcpy() once.

2010-04-02perf/scripts: Tuple was set from long in both branches in python_process_event()Tom Zanussi
This is a fix to the signed/unsigned field handling in the Python scripting engine, based on a patch from Roel Kluin. Basically, Python wants to use a PyInt (which is internally a long) if it can i.e. if the value will fit into that type. If not, it stores it into a PyLong, which isn't actually a long, but an arbitrary-precision integer variable. The code below is similar to to what Python does internally, and it seems to work as expected on the x86 and x86_64 sytems I tested it on.

2010-04-02perf, x86: Fix callgraphs of 32-bit processes on 64-bit kernelsTorok Edwin
When profiling a 32-bit process on a 64-bit kernel, callgraph tracing stopped after the first function, because it has seen a garbage memory address (tried to interpret the frame pointer, and return address as a 64-bit pointer). Fix this by using a struct stack_frame with 32-bit pointers when the TIF_IA32 flag is set. Note that TIF_IA32 flag must be used, and not is_compat_task(), because the latter is only set when the 32-bit process is executing a syscall, which may not always be the case (when tracing page fault events for example).

2010-04-02perf, x86: Fix AMD hotplug & constraint initializationPeter Zijlstra
Commit 3f6da39 ("perf: Rework and fix the arch CPU-hotplug hooks") moved the amd northbridge allocation from CPUS_ONLINE to CPUS_PREPARE_UP however amd_nb_id() doesn't work yet on prepare so it would simply bail basically reverting to a state where we do not properly track node wide constraints - causing weird perf results.

2010-04-01oom: fix the unsafe usage of badness() in proc_oom_score()Oleg Nesterov
proc_oom_score(task) has a reference to task_struct, but that is all. If this task was already released before we take tasklist_lock - we can't use task->group_leader, it points to nowhere - it is not safe to call badness() even if this task is ->group_leader, has_intersects_mems_allowed() assumes it is safe to iterate over ->thread_group list. - even worse, badness() can hit ->signal == NULL Add the pid_alive() check to ensure __unhash_process() was not called. Also, use "task" instead of task->group_leader. badness() should return the same result for any sub-thread. Currently this is not true, but this should be changed anyway.

2010-04-01microblaze: Support word copying in copy_tofrom_userMichal Simek
Word copying is used only for aligned addresses. Here is space for improving to use any better copying technique. Look at memcpy implementation. Signed-off-by: Michal Simek <monstr@monstr.eu>
