[Adeos-main] [pull request] Improve ftrace interaction

[Jan Kiszka <jan.kiszka@domain.hid>]

The following changes since commit 7c90959b7e4eb5ef8a775ec17005c23f30daade1:
  Philippe Gerum (1):
        ipipe: introduce 3-level IRQ pending map

are available in the git repository at:

  git://git.kiszka.org/ipipe-2.6 queues/2.6.32-noarch

These patches address various possible configuration errors around
ftrace that can cause hard crashes over I-pipe kernels. Moreover, one
patch enables the safe use of ftrace's PID filtering that comes for free
for the I-pipe tracer now.

The patches also apply on 2.6.33-noarch but were only tested on
2.6.32-x86.


Jan Kiszka (5):
      Use ipipe_safe_current in ftrace_pid_func
      Prevent unsafe ftrace usage over I-pipe
      Disable branch tracing/profiling under I-pipe
      Do no kill ftrace on failing function test
      Fix ipipe_safe_current definition for !CONFIG_IPIPE
