      [POWERPC] Fix build errors when BLOCK=n · 576e393e
      由 Emil Medve 提交于 
      These are the symptom error messages:

The fix tries to use the smallest scope CONFIG_* symbols that will fix
the build problem.  In this case <linux/ide.h> needs to be included
only if IDE=y or IDE=m were selected.  Also, ppc_ide_md is needed only
if BLK_DEV_IDE=y or BLK_DEV_IDE=m

Moved the EXPORT_SYMBOL(ppc_ide_md) from ppc_ksysms.c next to its
declaration in setup_32.c which made <linux/ide.h> not needed. With
<linux/ide.h> gone from ppc_ksyms.c, <asm/cacheflush.h> is needed to
address the following warnings and errors:

  CC      arch/powerpc/kernel/ppc_ksyms.o

      [POWERPC] Avoid pointless WARN_ON(irqs_disabled()) from panic codepath · 8fd7675c
      由 Satyam Sharma 提交于 
      > ------------[ cut here ]------------
> Badness at arch/powerpc/kernel/smp.c:202

comes when smp_call_function_map() has been called with irqs disabled,
which is illegal. However, there is a special case, the panic() codepath,
when we do not want to warn about this -- warning at that time is pointless
anyway, and only serves to scroll away the *real* cause of the panic and
distracts from the real bug.

* So let's extract the WARN_ON() from smp_call_function_map() into all its
  callers -- smp_call_function() and smp_call_function_single()

* Also, introduce another caller of smp_call_function_map(), namely
  __smp_call_function() (and make smp_call_function() a wrapper over this)
  which does *not* warn about disabled irqs

* Use this __smp_call_function() from the panic codepath's smp_send_stop()

We also end having to move code of smp_send_stop() below the definition
of __smp_call_function().

      [POWERPC] add Kconfig option for optimizing for cell · 3164cccd
      由 Arnd Bergmann 提交于 
      Since the PPE on cell is an in-order core, it suffers significantly
from wrong instruction scheduling.  This adds a Kconfig option that
enables passing -mtune=cell to gcc in order to generate object
code that runs well on cell.
