Justin Hibbits ec17d5e06a powerpc/pmap: Tighten condition for removing tracked pages in Book-E pmap
There are cases where there's no vm_page_t structure for a given physical
address, such as the CCSR.  In this case, trying to obtain the
md.page_tracked struct member would lead to a NULL dereference, and panic.
Tighten this up by checking for kernel_pmap AND that the page structure
actually exists before dereferencing.  The flag can only be set when it's
tracked in the kernel pmap anyway.
