This reverts the parent commit.

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.

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.

When au1000_eth probes the MII bus for PHY address, if we do not set au1000_eth platform data's phy_search_highest_address, the MII probing logic will exit early and will assume a valid PHY is found at address 0.

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.

Leverage the commit for ARM by Will Deacon: - 446a5a8b 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.

Ignore events that are in off/error state or belong to a different PMU. This patch originates from the following commit for ARM by Will Deacon: - 65b4711f ARM: 6352/1: perf: fix event validation The validate_event function in the ARM perf events backend has the following problems: 1.) Events that are disabled count towards the cost. 2.) Events associated with other PMUs [for example, software events or breakpoints] do not count towards the cost, but do fail validation, causing the group to fail. This patch changes validate_event so that it ignores events in the PERF_EVENT_STATE_OFF state or that are scheduled for other PMUs.

This is the MIPS part of the following commits by Peter Zijlstra: - a4eaf7f1 perf: Rework the PMU methods Replace pmu::{enable,disable,start,stop,unthrottle} with pmu::{add,del,start,stop}, all of which take a flags argument. 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. - 33696fc0 perf: Per PMU disable Changes perf_disable() into perf_pmu_disable(). - 24cd7f54 perf: Reduce perf_disable() usage Since the current perf_disable() usage is only an optimization, remove it for now. This eases the removal of the __weak hw_perf_enable() interface. - b0a873eb perf: Register PMU implementations Simple registration interface for struct pmu, this provides the infrastructure for removing all the weak functions. - 51b0fe39 perf: Deconstify struct pmu sed -ie 's/const struct pmu\>/struct pmu/g' `git grep -l "const struct pmu\>"` Reported-by: NWu Zhangjin <wuzhangjin@gmail.com> Acked-by: NDavid Daney <ddaney@caviumnetworks.com> Signed-off-by: NDeng-Cheng Zhu <dengcheng.zhu@gmail.com> To: a.p.zijlstra@chello.nl To: fweisbec@gmail.com To: will.deacon@arm.com Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Cc: wuzhangjin@gmail.com Cc: paulus@samba.org Cc: mingo@elte.hu Cc: acme@redhat.com Cc: dengcheng.zhu@gmail.com Cc: matt@console-pimps.org Cc: sshtylyov@mvista.com Cc: ddaney@caviumnetworks.com Patchwork: http://patchwork.linux-mips.org/patch/2012/Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

This is the MIPS part of the following commit by Peter Zijlstra: - e360adbe 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.

The old prepare_ftrace_return() for MIPS is confused and have introduced some problem. This patch cleans up the names of the arguments, variables and related functions. For MIPS, the 2nd argument of prepare_ftrace_return() is not really the 'selfpc' described in ftrace-design.txt but instead it is the self return address. This did break the compatibility of the generic interface but really reduced one unneeded calculation for to get the current function name, the parent return address and the self return address are enough, no need to tranform the self return address to the self address. But set_graph_function of function graph tracer is an exception, it does need the 2nd argument of prepare_ftrace_return() as 'selfpc', for it will use 'selfpc' to match user's configuration of function graph entries, but in reality, it doesn't need the 'selfpc' but the recorded ip address of the mcount calling site in the __mcount_loc section. So, the 2nd argument of prepare_ftrace_return() is not important, the real requirement is the right recorded ip address should be calculated and assign to trace.func, this will be fixed in the next patches.

The kernel automatically evaluates partition tables of storage devices.

In more detail: for (i = 0 ; i < le16_to_cpu(label->d_npartitions); i++, partition++) { iterates from 0 to d_npartitions - 1, where d_npartitions is read from the partition table without validation and partition is a pointer to an array of at most 8 d_partitions.

Using __get_user_check(x, ptr++, size) leads to double increment of pointer. This macro uses the macro get_user directly, which itself is used in this way (get_user(x, ptr++)) in some functions of the kernel. The patch fixes the error.

Setting the pci ops on subsys initcall unconditionally will break multi platform kernels on anything except ce4100. Use x86_init.pci.init ops to call this only on real ce4100 platforms.
