This patch fixes the undefined instruction oops due to execution
of thumb-2 code in ARM mode. The zero bit in the symbol address
returned by kallsyms_lookup_name is not set, leading to switching
to ARM mode that generates oops while executing thumb-2 code. For
detailed discussion, see [1].

Perf counter context info needs to be at fixed addresses
Fixes a kernel oops when using perf counter with multiple contexts. The
cpu hotplug notifier callback needs to have the callback notifier block
at a fixed address, but the context array may move as it is expanded.
The reason why we use a context array instead of an array of pointers is
to minimize the amount of memory accesses in the tracing hot path.
Let's special-case perf counters and put them in their own memory region
to account for cpu hotplug requirements.

sched instrumentation: show user-visible prio
/proc exports task_prio priority (offset - MAX_RT_PRIO). Export the
user-visible priority from scheduler events rather than the
implementation-specific priority.

scheduler instrumentation: rename "pid" fields to "tid"
The Linux getpid(), gettid() ABIs present "tid == thread id" and "pid ==
process id".
The internal Linux kernel representation is "pid == thread id" and "tgid
== process id".
Given that we want to expose an ABI to end-users that matches the
vision of user-space (rather than that of the implementation), use "tid"
field names to represent thread ids in the sched events.
