I took a quick look through the patches - here are some comments:
uml-clean-arch_switch -
This chunk is strange:
@@ -141,7 +148,6 @@ static void new_thread_handler(int sig)
set_cmdline("(kernel thread)");
change_sig(SIGUSR1, 1);
- change_sig(SIGVTALRM, 1);
change_sig(SIGPROF, 1);
local_irq_enable();
if(!run_kernel_thread(fn, arg, ¤t->thread.exec_buf))
If you're fixing a bug, you should say what it is. But the original
looks right, since the process has been scheduled and is running on
its kernel stack, so it should be able to take timer interrupts now.
uml-add-tls-support -
copy_thread - OK for now, but we should move the CLONE_TLS bit into
arch code.
arch_ptrace - Do all arches have PTRACE_[GS]ET_THREAD_AREA, maybe move
inside an ifdef PTRACE_GET_THREAD_AREA
Any patches that change new files should be merged into this, I
think. That basically means that the stack will mostly collapse into
this one patch. I didn't see any patches which add new bits of
functionality which would make sense standalone.
global-ldt-sem - We should be using mutexes now, not semaphores
detect-2_4-host - is there no more direct way to detect TLS support?
undo-global-ldt-sem - what's so horrible about the global? it won't
be highly contended, so making a single mutex saves memory from every
ldt.
