This series reduces by 70% the time required to activate
ftrace on an 8xx with CONFIG_STRICT_KERNEL_RWX.
Measure is performed in function ftrace_replace_code() using mftb()
around the loop.
With the series,
- Without CONFIG_STRICT_KERNEL_RWX, 416000 TB ticks are measured.
- With CONFIG_STRICT_KERNEL_RWX, 546000 TB ticks are measured.

Patch 2 was the keystone of this series. What happened to it ?
It broke on 64-bit. I think I know why but I haven't had time to test
it. Will try and get it fixed in the next day or two.
You didn't find any solution at the end, or didn't have time ?
What was the problem exactly ? I made a quick try on QEMU and it was
working as expected.
Should I make it a ppc32-only change ?
