| |
Hi all,
This lacks the first 17 patches of the v3 posting which are en-route to tip/core/objtool and should show up there somewhere later this evening.
As should be familiar by now; these patches implement the noinstr (no-instrument) validation in objtool as requested by Thomas, to ensure critical code (entry for now, idle later) run no unexpected code.
Functions are marked with: noinstr, which implies notrace, noinline and sticks things in the .noinstr.text section. Such functions can then use instr_begin() and instr_end() to allow calls to code outside of this section in sanctioned areas.
