      x86: Allow FPU to be used at interrupt time even with eagerfpu · 5187b28f
      Pekka Riikonen authored
      With the addition of eagerfpu the irq_fpu_usable() now returns false
      negatives especially in the case of ksoftirqd and interrupted idle task,
      two common cases for FPU use for example in networking/crypto.  With
      eagerfpu=off FPU use is possible in those contexts.  This is because of
      the eagerfpu check in interrupted_kernel_fpu_idle():
      
      ...
        * For now, with eagerfpu we will return interrupted kernel FPU
        * state as not-idle. TBD: Ideally we can change the return value
        * to something like __thread_has_fpu(current). But we need to
        * be careful of doing __thread_clear_has_fpu() before saving
        * the FPU etc for supporting nested uses etc. For now, take
        * the simple route!
      ...
       	if (use_eager_fpu())
       		return 0;
      
      As eagerfpu is automatically "on" on those CPUs that also have the
      features like AES-NI this patch changes the eagerfpu check to return 1 in
      case the kernel_fpu_begin() has not been said yet.  Once it has been the
      __thread_has_fpu() will start returning 0.
      
      Notice that with eagerfpu the __thread_has_fpu is always true initially.
      FPU use is thus always possible no matter what task is under us, unless
      the state has already been saved with kernel_fpu_begin().
      
      [ hpa: this is a performance regression, not a correctness regression,
        but since it can be quite serious on CPUs which need encryption at
        interrupt time I am marking this for urgent/stable. ]

      x86, crc32-pclmul: Fix build with older binutils · 2baad612
      Jan Beulich authored
      binutils prior to 2.18 (e.g. the ones found on SLE10) don't support
      assembling PEXTRD, so a macro based approach like the one for PCLMULQDQ
      in the same file should be used.
      
      This requires making the helper macros capable of recognizing 32-bit
      general purpose register operands.

      MN10300: Enable IRQs more in system call exit work path · d17fc238
      David Howells authored
      Enable IRQs when calling schedule() for TIF_NEED_RESCHED and
      do_notify_resume().  If interrupts are enabled during do_notify_resume(), a
      warning can be seen (see lower down).
      
      Whilst we're at it, resume_userspace can be made local to entry.S as it is not
      called outside of there and it can be merged with the part of work_resched that
      occurs after schedule() is called.

      MN10300: Fix ret_from_kernel_thread · 1e00227d
      David Howells authored
      ret_from_kernel_thread needs to set A2 to the thread_info pointer before
      jumping to syscall_exit.
      
      Without this, we never correctly start userspace.
      
      This was caused by the rejuggling of the fork/exec paths in commit
