The optimization for small ranges failed to do so # when the virtual address was in the vmalloc or module space. # # - Unbreak the trace event registration for syscalls without arguments # caused by the refactoring of the SYSCALL_DEFINE0() macro. # # - Move the printk in the TSC deadline timer code to a place where it # is guaranteed to only be called once during boot and cannot be # rearmed by clearing warn_once after boot. If it's invoked post boot # then lockdep rightfully complains about a potential deadlock as the # calling context is different. # # - A series of fixes for objtool and the ORC unwinder addressing # variety of small issues: # # - Stack offset tracking for indirect CFAs in objtool ignored # subsequent pushs and pops # # - Repair the unwind hints in the register clearing entry ASM code # # - Make the unwinding in the low level exit to usermode code stop # after switching to the trampoline stack. The unwind hint is no # longer valid and the ORC unwinder emits a warning as it can't # find the registers anymore. # # - Fix unwind hints in switch_to_asm() and rewind_stack_do_exit() # which caused objtool to generate bogus ORC data. # # - Prevent unwinder warnings when dumping the stack of a # non-current task as there is no way to be sure about the # validity because the dumped stack can be a moving target. # # - Make the ORC unwinder behave the same way as the frame pointer # unwinder when dumping an inactive tasks stack and do not skip # the first frame. # # - Prevent ORC unwinding before ORC data has been initialized # # - Immediately terminate unwinding when a unknown ORC entry type # is found. # # - Prevent premature stop of the unwinder caused by IRET frames. # # - Fix another infinite loop in objtool caused by a negative # offset which was not catched. # # - Address a few build warnings in the ORC unwinder and add # missing static/ro_after_init annotations" # # *
