2ed84eeb88 trace: rename unlikely profiler to branch profiler
Impact: name change of unlikely tracer and profiler

Ingo Molnar suggested changing the config from UNLIKELY_PROFILE
to BRANCH_PROFILING. I never did like the "unlikely" name so I
went one step farther, and renamed all the unlikely configurations
to a "BRANCH" variant.

2b7d0390a6 tracing: branch tracer, fix vdso crash
Impact: fix bootup crash

the branch tracer missed arch/x86/vdso/vclock_gettime.c from
disabling tracing, which caused such bootup crashes:

  [  201.840097] init[1]: segfault at 7fffed3fe7c0 ip 00007fffed3fea2e sp 000077

also clean up the ugly ifdefs in arch/x86/kernel/vsyscall_64.c by
creating DISABLE_UNLIKELY_PROFILE facility for code to turn off
instrumentation on a per file basis.

23adec554a x86: add notrace annotations to vsyscall.
Add the notrace annotations to the vsyscall functions - there we are
not in kernel context yet, so the tracer function cannot (and must not)
be called.

a1289643ad x86: use explicit copy in vdso_gettimeofday()
Jeremy's gcc 3.4 seems to be unable to inline a 8 byte memcpy.  But the
vdso doesn't support external references.  Copy the structure members
of struct timezone explicitely instead.
