d7bae14707 TEMPORARY: schedule(): move threads when core is explicitly oversubscribed 2015-07-28 20:12:58 +09:00
Balazs Gerofi
9b1e691588 fix thread migration code (i.e., sched_setaffinity()) 
- moved migration code into idle() process and updated schedule() to detect
  when a thread has moved to another CPU in order to avoid doing housekeeping
  on behalf of the original one
- start CPU head from core 0
- keeps track of nested interrupts

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.

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".
