switches/ depends on RAPIDIO_DEBUG so the subdir-ccflags-y variant seems to be appropriate here. Signed-off-by:

The EXTRA_CFLAGS assignment in memstick/Makefile was not accomplishing anything because this flag only has effect on sources at the same level as the makefile (i.e., per directory). Since both core/ and host/ rely on MEMSTICK_DEBUG, the subdir-ccflags-y variant seems to be the appropriate choice. Signed-off-by:

This reverts the parent commit. I hate doing that, but it's generating some discussion ("half of it is right"), and since I am planning on doing the 2.6.38 release later today we can punt it to stable if required. Let's not rock the boat right now. Signed-off-by:Linus Torvalds <torvalds@linux-foundation.org>

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. Signed-off-by:

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. For MTX-1, the PHY is at address 31, and without this patch, the link detection/speed/duplex would not work correctly. CC: stable@kernel.org Signed-off-by:

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. Signed-off-by:

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.

This is the MIPS part of the following commits by Frederic Weisbecker: - f72c1a93 perf: Factorize callchain context handling Store the kernel and user contexts from the generic layer instead of archs, this gathers some repetitive code. - 56962b44 perf: Generalize some arch callchain code - Most archs use one callchain buffer per cpu, except x86 that needs to deal with NMIs. Provide a default perf_callchain_buffer() implementation that x86 overrides. - Centralize all the kernel/user regs handling and invoke new arch handlers from there: perf_callchain_user() / perf_callchain_kernel() That avoid all the user_mode(), current->mm checks and so... - Invert some parameters in perf_callchain_*() helpers: entry to the left, regs to the right, following the traditional (dst, src). - 70791ce9 perf: Generalize callchain_store() callchain_store() is the same on every archs, inline it in perf_event.h and rename it to perf_callchain_store() to avoid any collision. This removes repetitive code. - c1a65932 perf: Drop unappropriate tests on arch callchains Drop the TASK_RUNNING test on user tasks for callchains as this check doesn't seem to make any sense. Also remove the tests for !current that is not supposed to happen and current->pid as this should be handled at the generic level, with exclude_idle attribute. Reported-by:

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. Acked-by:

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:

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. Reported-by:
