Part of the memory (first 512kbytes) was # mapped with BATs instead of page table, but it was also entirely # mapped as executable. # # In commit 385e89d5b20f ("powerpc/mm: add exec protection on # powerpc 603"), we started adding exec protection to some 6xx, namely # the 603, for pages mapped via pagetables. # # Then, in commit 63b2bc619565 ("powerpc/mm/32s: Use BATs for # STRICT_KERNEL_RWX"), the exec protection was extended to BAT mapped # memory, so that really only the kernel text could be executed. # # The problem here is that kexec is based on copying some code into # upper part of memory then executing it from there in order to install # a fresh new kernel at its definitive location. # # However, the code is position independant and first part of it is # just there to deactivate the MMU and jump to the second part. So it # is possible to run this first part inplace instead of running the # copy. Once the MMU is off, there is no protection anymore and the # second part of the code will just run as before. # # Reported-by: Aaro Koskinen <aaro.koskinen@iki.fi> # Fixes: 63b2bc619565
