Dear RT folks!

I'm pleased to announce the v3.12.5-rt7 patch set.

Changes since v3.12.5-rt6
- the ptrace fix got a little wrong in check_task_state() and we had two
  return 0 which ensured that ptrace did not work. Noticed by Mike
  Galbraith.

Known issues:

      - bcache is disabled.

      - Brian Silverman reported a BUG (via Debian BTS) where gdb's
        record command does something nasty and causes a double fault on
        x86-64 kernel with 32bit userland (the debugged application).
        32bit and 64bit setup are not kernels are not affected. As far
        as I understand the problem so far, it is limited to x86.

The delta patch against v3.12.5-rt6 is appended below and can be found
here:
