LINEAR16 data format is unsigned, not signed. Impact is that affected attributes report negative values in the upper half of the supported value range. Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
2011-03-15hwmon: (pmbus) Continuously update temperature limit registersGuenter Roeck
PMBus only has one set of limit registers for up to three temperature sensors. Thus, changing a limit for one of the temperature sensors affects limits for other temperature sensors in the same page (and potentially multiple pages depending on the chip implementation). To handle this situation, re-read all temperature limit registers when updating sensor data. This way, all affected temperature limits are updated whenever the limit for a single sensor is changed.

2011-03-15hwmon: (pmbus) Improve support for paged temperature sensorsGuenter Roeck
Assumption so far was that PMBus devices would support TEMP2 and TEMP3 registers only on page 0, and that only the TEMP1 register would be used/supported on other pages. Turns out that is not correct. UCD92xx devices support TEMP1 and TEMP2 on page 0, and TEMP2 on other pages. So it is necessary to change the core code such that it does not make a page based assumptions about temperature register support. Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
2011-03-15hwmon: (pmbus) Improve support for paged fansGuenter Roeck
So far, it seemed like fans would either all be in page 0, or that there would be one page per fan. Turns out this was a wrong assumption. There is at least one PMBus fan controller which supports three pages with four fans each. Update code to handle this situation.

2011-03-15hwmon: (pmbus) More stringent checking of VOUT_MODE registerGuenter Roeck
Some PMBus chips do not support the VOUT_MODE register. To make matters worse, such chips may not return an error when reading the register either, but instead return 0xff. Check if the register exists using pmbus_check_byte_register() before reading its value. In addition, validate the returned value and ignore it if it is 0xff (which is invalid).

2011-03-15hwmon: (lm85) Do not update hysteresis and temp_auto_off if auto_temp_min is ↵Guenter Roeck
changed So far, the driver updates temp_auto_hyst and temp_auto_off if temp_auto_min changes. This may cause problems if temp_auto_off was not configured before configuring temp_auto_min, because one of the variables used (off_desired) is not initialized in this case. To simplify the code, and for consistency with other drivers, no longer update the delta between "min" and "off" until the user sets the "off" value again.

2011-03-14oom: oom_kill_process: fix the child_points logicOleg Nesterov
oom_kill_process() starts with victim_points == 0. This means that (most likely) any child has more points and can be killed erroneously. Also, "children has a different mm" doesn't match the reality, we should check child->mm != t->mm. This check is not exactly correct if t->mm == NULL but this doesn't really matter, oom_kill_task() will kill them anyway. Note: "Kill all processes sharing p->mm" in oom_kill_task() is wrong too.

2011-03-14MIPS: Alchemy: Fix reset for MTX-1 and XXS1500Florian Fainelli
Since commit 32fd6901 (MIPS: Alchemy: get rid of common/reset.c) Alchemy-based boards use their own reset function. For MTX-1 and XXS1500, the reset function pokes at the BCSR.SYSTEM_RESET register, but this does not work. According to Bruno Randolf, this was not tested when written. Previously, the generic au1000_restart() routine called the board specific reset function, which for MTX-1 and XXS1500 did not work, but finally made a jump to the reset vector, which really triggers a system restart. Fix reboot for both targets by jumping to the reset vector.

2011-03-14MIPS: Move idle task creation to work queueMaksim Rayskiy
To avoid forking usermode thread when creating an idle task, move fork_idle to a work queue. If kernel starts with maxcpus= option which does not bring all available cpus online at boot time, idle tasks for offline cpus are not created. If later offline cpus are hotplugged through sysfs, __cpu_up is called in the context of the user task, and fork_idle copies its non-zero mm pointer. This causes BUG() in per_cpu_trap_init. This also avoids issues with resource limits of the CPU writing to sysfs, containers, maybe others.

2011-03-14MIPS, Perf-events: Use unsigned delta for right shift in event updateDeng-Cheng Zhu
Leverage the commit for ARM by Will Deacon: - 446a5a8b1eb91a6990e5c8fe29f14e7a95b69132 ARM: 6205/1: perf: ensure counter delta is treated as unsigned Hardware performance counters on ARM are 32-bits wide but atomic64_t variables are used to represent counter data in the hw_perf_event structure. The armpmu_event_update function right-shifts a signed 64-bit delta variable and adds the result to the event count. This can lead to shifting in sign-bits if the MSB of the 32-bit counter value is set. This results in perf output such as: Performance counter stats for 'sleep 20': 18446744073460670464 cycles <-- 0xFFFFFFFFF12A6000 7783773 instructions # 0.000 IPC 465 context-switches 161 page-faults 1172393 branches 20.154242147 seconds time elapsed This patch ensures that the delta value is treated as unsigned so that the right shift sets the upper bits to zero.

The new interface extends the capability to stop a counter while keeping it scheduled on the PMU. We replace the throttled state with the generic stopped state. This also allows us to efficiently stop/start counters over certain code paths (like IRQ handlers). It also allows scheduling a counter without it starting, allowing for a generic frozen state (useful for rotating stopped counters). The stopped state is implemented in two different ways, depending on how the architecture implemented the throttled state: 1) We disable the counter: a) the pmu has per-counter enable bits, we flip that b) we program a NOP event, preserving the counter state 2) We store the counter state and ignore all read/overflow events For MIPSXX, the stopped state is implemented in the way of 1.b as above. - 33696fc0d141bbbcb12f75b69608ea83282e3117 perf: Per PMU disable Changes perf_disable() into perf_pmu_disable(). - 24cd7f54a0d47e1d5b3de29e2456bfbd2d8447b7 perf: Reduce perf_disable() usage Since the current perf_disable() usage is only an optimization, remove it for now.

2011-03-14MIPS, Perf-events: Work with irq_workDeng-Cheng Zhu
This is the MIPS part of the following commit by Peter Zijlstra: - e360adbe29241a0194e10e20595360dd7b98a2b3 irq_work: Add generic hardirq context callbacks Provide a mechanism that allows running code in IRQ context. It is most useful for NMI code that needs to interact with the rest of the system -- like wakeup a task to drain buffers. Perf currently has such a mechanism, so extract that and provide it as a generic feature, independent of perf so that others may also benefit. The IRQ context callback is generated through self-IPIs where possible, or on architectures like powerpc the decrementer (the built-in timer facility) is set to generate an interrupt immediately. Architectures that don't have anything like this get to do with a callback from the timer tick. These architectures can call irq_work_run() at the tail of any IRQ handlers that might enqueue such work (like the perf IRQ handler) to avoid undue latencies in processing the work. For MIPSXX, we need to call irq_work_run() at the tail of the perf IRQ handler as described above.

2011-03-14MIPS: Fix GCC-4.6 'set but not used' warning in ieee754int.hDavid Daney
GCC-4.6 can find more unused code than previous versions could. In the case of arch/mips/math-emu/ieee754int.h, the COMPXSP and COMPXDP macros are used in several places, but a couple of them leave xs unused. The easiest thing to do is mark it as __maybe_unused to quiet the warning.

The variable arg3 in _sys_sysmips() is unused. Remove it. Signed-off-by: David Daney <ddaney@caviumnetworks.com> To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/2034/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2011-03-14MIPS: Fix GCC-4.6 'set but not used' warning in signal*.cDavid Daney
GCC-4.6 can find more unused code than previous versions could. In the case of protected_restore_fp_context{,32}, the variable tmp is really used. Its use is tricky in that we really care about the side effects of the __put_user() calls. So we must mark tmp with __maybe_unused to quiet the warning.

2011-03-14MIPS: Loongson: Remove ad-hoc cmdline defaultRobert Millan
Loongson builds have an ad-hoc cmdline default of "console=ttyS0,115200 root=/dev/hda1". These settings come from a vendor; I remember builds from Lemote branch requiring a "console=tty" override in order to get a working console. At least on Yeeloong, they're particularly useless: there's no external serial port, and the IDE drive is now recognised as /dev/sda.
