[Qemu-devel] Clean cache related code which was used only by PPC hosts

[Stefan Weil]

These patches clean an issue which was discussed some weeks ago
(http://lists.nongnu.org/archive/html/qemu-devel/2011-09/msg02279.html):

Code which was only needed for the PPC* tcg targets
(flush_icache_range, qemu_cache_utils_init)
was defined in files used by all host architectures.

The 1st patch is trivial and only included because I stumbled
across flush_icache_range in a linux-user file.

The 2nd patch works for non PPC* hosts, but I could not test
it on PPC* host variants. I only moved and formatted code,
so hopefully it won't break anything for PPC*.

[PATCH 1/2] linux-user: Remove unused code
[PATCH 2/2] tcg/ppc*: Move cache initialization to ppc specific code

Kind regards,

Stefan Weil
