  "description": "In the Linux kernel, the following vulnerability has been resolved:  m68k: mm: Move initrd phys_to_virt handling after paging_init()  When booting with an initial ramdisk on platforms where physical memory does not start at address zero (e.g. on Amiga):      initrd: 0ef0602c - 0f800000     Zone ranges:       DMA      [mem 0x0000000008000000-0x000000f7ffffffff]       Normal   empty     Movable zone start for each node     Early memory node ranges       node   0: [mem 0x0000000008000000-0x000000000f7fffff]     Initmem setup node 0 [mem 0x0000000008000000-0x000000000f7fffff]     Unable to handle kernel access at virtual address (ptrval)     Oops: 00000000     Modules linked in:     PC: [\u003C00201d3c\u003E] memcmp\u002B0x28/0x56  As phys_to_virt() relies on m68k_memoffset and module_fixup(), it must not be called before paging_init().  Hence postpone the phys_to_virt handling for the initial ramdisk until after calling paging_init().  While at it, reduce #ifdef clutter by using IS_ENABLED() instead.",
