This patch set implements STRICT_KERNEL_RWX on Powerpc32
after fixing a few issues related to kernel code page protection.
At the end we take the opportunity to get rid of some unneccessary/outdated
fixmap stuff.
Changes from v1 to v2:
* Rebased on latest linux-next following including of STRICT_KERNEL_RWX for
PPC64
* Removed from the serie the two patches already applied.
