* Generic ptrace interface that exports the architecture specific regsets

[33] Fix | Delete

* using the corresponding NT_* types (which are also used in the core dump).

[34] Fix | Delete

* Please note that the NT_PRSTATUS note type in a core dump contains a full

[35] Fix | Delete

* 'struct elf_prstatus'. But the user_regset for NT_PRSTATUS contains just the

[36] Fix | Delete

* elf_gregset_t that is the pr_reg field of 'struct elf_prstatus'. For all the

[37] Fix | Delete

* other user_regset flavors, the user_regset layout and the ELF core dump note

[38] Fix | Delete

* payload are exactly the same layout.

[39] Fix | Delete

*

[40] Fix | Delete

* This interface usage is as follows:

[41] Fix | Delete

* struct iovec iov = { buf, len};

[42] Fix | Delete

*

[43] Fix | Delete

* ret = ptrace(PTRACE_GETREGSET/PTRACE_SETREGSET, pid, NT_XXX_TYPE, &iov);

[44] Fix | Delete

*

[45] Fix | Delete

* On the successful completion, iov.len will be updated by the kernel,

[46] Fix | Delete

* specifying how much the kernel has written/read to/from the user's iov.buf.
