Stephane noticed that the ANY flag was in generic arch code, and Cyrill reported that it broke the P4 code. Solve this by merging x86_pmu::raw_event into x86_pmu::hw_config and provide intel_pmu and amd_pmu specific versions of this callback. The intel_pmu one deals with the ANY flag, the amd_pmu adds the few extra event bits AMD64 has.

ARCH_PERFMON_EVENTSEL bit masks are often used in the kernel. This patch adds macros for the bit masks and removes local defines. The function intel_pmu_raw_event() becomes x86_pmu_raw_event() which is generic for x86 models and same also for p6. Duplicate code is removed.

The big rename: cdd6c482 perf: Do the big rename: Performance Counters -> Performance Events accidentally renamed some members of stucts that were named after registers in the spec. To avoid confusion this patch reverts some changes.

When profiling a 32-bit process on a 64-bit kernel, callgraph tracing stopped after the first function, because it has seen a garbage memory address (tried to interpret the frame pointer, and return address as a 64-bit pointer). Fix this by using a struct stack_frame with 32-bit pointers when the TIF_IA32 flag is set. Note that TIF_IA32 flag must be used, and not is_compat_task(), because the latter is only set when the 32-bit process is executing a syscall, which may not always be the case (when tracing page fault events for example).

Commit 3f6da390 ("perf: Rework and fix the arch CPU-hotplug hooks") moved the amd northbridge allocation from CPUS_ONLINE to CPUS_PREPARE_UP however amd_nb_id() doesn't work yet on prepare so it would simply bail basically reverting to a state where we do not properly track node wide constraints - causing weird perf results. Fix up the AMD NorthBridge initialization code by allocating from CPU_UP_PREPARE and installing it from CPU_STARTING once we have the proper nb_id. It also properly deals with the allocation failing.

proc_oom_score(task) has a reference to task_struct, but that is all. If this task was already released before we take tasklist_lock - we can't use task->group_leader, it points to nowhere - it is not safe to call badness() even if this task is ->group_leader, has_intersects_mems_allowed() assumes it is safe to iterate over ->thread_group list. - even worse, badness() can hit ->signal == NULL Add the pid_alive() check to ensure __unhash_process() was not called. Also, use "task" instead of task->group_leader. badness() should return the same result for any sub-thread. Currently this is not true, but this should be changed anyway.

When the system has no lmb bram, main memory should be start from zero because of microblaze vectors. DTS fragment could look like: DDR2_SDRAM: memory@0 { device_type = "memory"; reg = < 0x0 0x10000000 >; } ; Then you have to setup CONFIG_KERNEL_BASE_ADDR=0 which caused that kernel physical start address will be zero. On reset vector place will be jump to 0x100 and on 0x100 starts kernel text. You have to solve how to load the kernel before cpu starts. Tested with XMD.
