Susumu Komaeandpostpeta e30946f1f0 fix PTRACE_CONT may cause error. 
refs #369
 2015-01-29 14:10:31 +09:00
Susumu Komaeandpostpeta c3ade864d9 fix PTRACE_PEEKUSER, PTRACE_POKEUSER, PTRACE_GETREGS. 
support PTRACE_SETREGS.
  In struct process, add 'unsigned long *ptrace_debugreg', instead of 'struct user *userp'.
  debug registers are read/written from/to ptrace_debugreg, save/restore in schedule().
  most general registers are proc->uctx.
  fs_base is proc->thread.tlsblock_base.
  gs_base,ds,es,fs,gs and orig_rax are uncompleted.
  other members in 'struct user' are ignored, same as Linux implementation.

NAKAMURA Gou 0942bf0ce0 make dkprintf() evaluate its parameters always 
Parameters of dkprintf() should be evaluated even if dkprintf() is
disabled.  Because this enables to find expression of parameter obsolete
and to avoid unnecessary compiler warnings such as "unused variable".

bgerofi@riken.jpandBalazs Gerofi bgerofi@riken.jp b2cab453f1 clone(): do not allow setting CLONE_THREAD and CLONE_VM separately 
XXX: When CLONE_VM is set but CLONE_THREAD is not the new thread is
meant to have its own thread group, i.e., when calling exit_group()
the cloner thread wouldn't be killed. However, this is a problem on
the Linux side because we do not invoke clone in mcexec when threads
are created. Thus, currently no support for this combination is
provided.

NAKAMURA Gou 11947a4ce3 initialize and propagate a cpu affinity (temporary fix)

fix.

NAKAMURA Gou d2cb890cdd idle(): recheck runq just before cpu status check 
There is a problem which causes wait4(2) hang when wait4(2) called by a
process races with its child process termination.
This is a quick fix for this problem. See idle().
