/* On architectures, that started to support PTRACE_O_TRACESYSGOOD
|
|
* in linux 2.4, there are two different definitions of
|
|
* PTRACE_SETOPTIONS: linux 2.4 uses 21 while linux 2.6 uses 0x4200.
|
|
* For binary compatibility, 2.6 also supports the old "21", named
|
|
* PTRACE_OLDSETOPTION. On these architectures, UML always must use
|
|
* "21", to ensure the kernel runs on 2.4 and 2.6 host without
|
|
* recompilation. So, we use PTRACE_OLDSETOPTIONS in UML.
|
|
* We also want to be able to build the kernel on 2.4, which doesn't
|
|
* have PTRACE_OLDSETOPTIONS. So, if it is missing, we declare
|
|
* PTRACE_OLDSETOPTIONS to to be the same as PTRACE_SETOPTIONS.
|
|
*
|
|
* On architectures, that start to support PTRACE_O_TRACESYSGOOD on
|
|
* linux 2.6, PTRACE_OLDSETOPTIONS never is defined, and also isn't
|
|
* supported by the host kernel. In that case, our trick lets us use
|
|
* the new 0x4200 with the name PTRACE_OLDSETOPTIONS.
