2012-10-06mn10300: only add -mmem-funcs to KBUILD_CFLAGS if gcc supports itGeert Uytterhoeven
It seems the current (gcc 4.6.3) no longer provides this so make it conditional. As reported by Tony before, the mn10300 architecture cross-compiles with gcc-4.6.3 if -mmem-funcs is not added to KBUILD_CFLAGS.

2012-10-05ARM: 7548/1: include linux/sched.h in syscall.hWade Farnsworth
The syscall tracing patch introduces a compile bug in lttng-modules when the latter calls syscall_get_nr(), similar to the following: <path-to-linux>/arch/arm/include/asm/syscall.h:21:2: error: implicit declaration of function 'task_thread_info' [-Werror=implicit-function-declaration] The issue is that we are using task_thread_info() in the syscall_get_nr() function in asm/syscall.h, but not explicitly including sched.h from this file, so we can expect this bug might surface any time that syscall_get_nr() is called. Explicitly including sched.h solves the problem.

2012-10-05nohz: Fix one jiffy count too far in idle cputimeFrederic Weisbecker
When we stop the tick in idle, we save the current jiffies value in ts->idle_jiffies. This snapshot is substracted from the later value of jiffies when the tick is restarted and the resulting delta is accounted as idle cputime. This is how we handle the idle cputime accounting without the tick. But sometimes we need to schedule the next tick to some time in the future instead of completely stopping it. In this case, a tick may happen before we restart the periodic behaviour and from that tick we account one jiffy to idle cputime as usual but we also increment the ts->idle_jiffies snapshot by one so that when we compute the delta to account, we substract the one jiffy we just accounted. To prepare for stopping the tick outside idle, we introduced a check that prevents from fixing up that ts->idle_jiffies if we are not running the idle task. But we use idle_cpu() for that and this is a problem if we run the tick while another CPU remotely enqueues a ttwu to our runqueue: CPU 0: CPU 1: tick_sched_timer() { ttwu_queue_remote() if (idle_cpu(CPU 0)) ts->idle_jiffies++; } Here, idle_cpu() notes that &rq->wake_list is not empty and hence won't consider the CPU as idle. As a result, ts->idle_jiffies won't be incremented. But this is wrong because we actually account the current jiffy to idle cputime. And that jiffy won't get substracted from the nohz time delta. So in the end, this jiffy is accounted twice. Fix this by changing idle_cpu(smp_processor_id()) with is_idle_task(current). This way the jiffy is substracted correctly even if a ttwu operation is enqueued on the CPU.

2012-10-04Input: wacom - introduce wacom_fix_phy_from_hidJason Gerecke
The Cintiq 24HD touch cannot use wacom_set_phy_from_res to determine the physical size of the touch sensor since the pen and touch are on separate USB devices. The physical size is, however, provided in the HID descriptor, just scaled to a unit we don't use. This patch introduces the function wacom_fix_phy_from_hid to let us make use of the unit and exponent data provided by HID to set the [xy]_phy variables to an appropriate value. This function relies on a trimmed-down version of hidinput_calc_abs_res from the hid-input.c.
