Tomas Hruby 87c576584d Internal 64M buffer for profiling ...

- when profiling is compiled in kernel includes a 64M buffer for
  sample

- 64M is the default used by profile tool as its buffer

- when using nmi profiling it is not possible to always copy sample
  stright to userland as the nmi may (and does) happen in bad moments

- reduces sampling overhead as samples are copied out only when
  profiling stops
