In the watchdog-test program and watchdog-api.txt, pass the values to the WDIOC_SETOPTIONS ioctl as a pointer to an integer containing the values intead of directly in the third ioctl argument. The actual watchdog drivers in drivers/watchdog don't read the options directly from the argument but use get_user and copy_from_user.

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: NJason Wessel <jason.wessel@windriver.com>

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.

While the MMUCR.URB and ITLB/UTLB differentiation works fine for all SH-4 and later TLBs, these features are absent on SH-3. This splits out local_flush_tlb_all() in to SH-4 and PTEAEX copies while restoring the old SH-3 one, subsequently fixing up the build. This will probably want some further reordering and tidying in the future, but that's out of scope at present. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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.

When the system has no lmb bram, main memory should be start from zero because of microblaze vectors. DTS fragment could look like: DDR2_SDRAM: memory@0 { device_type = "memory"; reg = < 0x0 0x10000000 >; } ; Then you have to setup CONFIG_KERNEL_BASE_ADDR=0 which caused that kernel physical start address will be zero. On reset vector place will be jump to 0x100 and on 0x100 starts kernel text. You have to solve how to load the kernel before cpu starts. Tested with XMD.
