Andreas Kling ae2d72377d Kernel: Enable the x86 WP bit to catch invalid memory writes in ring 0 
Setting this bit will cause the CPU to generate a page fault when
writing to read-only memory, even if we're executing in the kernel.

Seemingly the only change needed to make this work was to have the
inode-backed page fault handler use a temporary mapping for writing
the read-from-disk data into the newly-allocated physical page.
