This patch set implements STRICT_KERNEL_RWX on Powerpc32
after fixing a few issues related to kernel code page protection.
It superseeds the previous patch set identified "Fix kernel protection
and implement CONFIG_DEBUG_RODATA on PPC32"
This set is based on Balbir Singh <bsinghar...@gmail.com> set identified
"Enable STRICT_KERNEL_RWX" and applies on top of it.
At the end we take the opportunity to get rid of some unneccessary/outdated
fixmap stuff.

powerpc/mm: rename map_page() to map_kernel_page() on PPC32
