2010-04-06Driver for Zipit Z2 battery chipMarek Vasut4-0/+352
This patch adds driver for Zipit Z2 battery chip called AER915. No details are known about the chip. The chip is available through I2C bus at address 0x55 and it's register 0x02 contains battery voltage.

2010-04-06ds2782_battery: Fix clientdata on removalWolfram Sang1-3/+0
Probably due to a copy & paste bug, clientdata was set again to the data structure (which is freed immediately afterwards) when it should be NULLed. Just remove the calls as the i2c-core does this automatically now.

2010-04-04proc: pagemap: Hold mmap_sem during page walkKAMEZAWA Hiroyuki1-49/+38
In initial design, walk_page_range() was designed just for walking page table and it didn't require mmap_sem. Now, find_vma() etc.. are used in walk_page_range() and we need mmap_sem around it. This patch adds mmap_sem around walk_page_range(). Because /proc/<pid>/pagemap's callback routine use put_user(), we have to get rid of it to do sane fix.

2010-04-02kgdb: eliminate kgdb_wait(), all cpus enter the same wayJason Wessel1-83/+82
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>

2010-04-02perf/scripts: Tuple was set from long in both branches in python_process_event()Tom Zanussi1-5/+12
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 Edwin2-5/+44
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).

2010-04-01oom: fix the unsafe usage of badness() in proc_oom_score()Oleg Nesterov1-2/+3
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.
