Rodriguez" List-Id: linux-arch.vger.kernel.org While dusting out the firmware loader closet I spotted a PAGE_KERNEL_* fallback hack. This hurts my eyes, and it should also be blinding others. Turns out we have other PAGE_KERNEL_* fallback hacks in other places. This moves them to asm-generic, and keeps track of architectures which need some love or review. At least 0-day was happy with the changes. Matthew Wilcox did put together a PAGE_KERNEL_RO patch for ia64, that needs review and testing, and if it goes well it should be merged. Luis R.
