Clean up and unify the NOP selection infrastructure:

- Make the atomic 5-byte NOP a part of the selection system.
- Pick NOPs once during early boot and then be done with it.

x86/tracing: comment need for atomic nop 2009-09-10T21:22:44+00:00 Steven Rostedt srostedt@redhat.com 2009-09-10T21:22:44+00:00 fc06b8520b3bf9aaeb2e27debe6719c215bd4916 The dynamic function tracer relys on the macro P6_NOP5 always being an atomic NOP. If for some reason it is changed to be two operations (like a nop2 nop3) it can faults within the kernel when the function tracer modifies the code. This patch adds a comment to note that the P6_NOPs are expected to be atomic. This will hopefully prevent anyone from changing that.
