| * | sanitize tsk_is_polling()Al Viro2012-10-0126-38/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make default just return 0. The current default (checking TIF_POLLING_NRFLAG) is taken to architectures that need it; ones that don't do polling in their idle threads don't need to defined TIF_POLLING_NRFLAG at all. ia64 defined both TS_POLLING (used by its tsk_is_polling()) and TIF_POLLING_NRFLAG (not used at all). Killed the latter... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| * | m68k: switch to generic sys_execve()/kernel_execve()Al Viro2012-10-015-37/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tricky part here is that task_pt_regs() on m68k works *only* for process inside do_signal(). However, we need something much simpler - pt_regs of a process inside do_signal() may be at different offsets from the stack bottom, depending on the way we'd entered the kernel, but for a task inside sys_execve() it *is* at constant offset. Moreover, for a kernel thread about to become a userland process the same location is also fine - setting sp to that will leave the kernel stack pointer at the very bottom of the kernel stack when we finally switch to userland.

| * | m68k: always set stack frame format for ColdFire on thread startGreg Ungerer2012-10-011-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The stack frame "format" field needs to be explicitly set on thread creation on ColdFire. For a normal long word aligned user stack pointer the frame format is 0x4. We were doing this for non-MMU ColdFire, but not for the case with MMU enabled. So fix it so we always do it if targeting ColdFire. The old code happend to rely on the stack frame format being inhereted from the process calling exec. Furture changes means that may not always work, so we really do want to set it explicitly. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | the only non-obvious part is that current_pt_regs() is really needed here - task_pt_regs() is NULL for kernel threads; it's OK for ptrace uses (the thing task_pt_regs() is intended for), but not for us. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | during hotplug The CPU hotplug callback related to writeback calls writeback_set_ratelimit() during every state change in the hotplug sequence. This is unnecessary since num_online_cpus() changes only once during the entire hotplug operation.
