#     powerpc/8xx: Map 32Mb of RAM at init.
#     
#     At the time being, initial MMU setup allows 24 Mbytes
#     of DATA and 8 Mbytes of code.
#     
#     Some debug setup like CONFIG_KASAN generate huge
#     kernels with text size over the 8M limit and data over the
#     24 Mbytes limit.
#     
#     Here is an 8xx kernel compiled with CONFIG_KASAN_INLINE for
#     one of my boards:
#     
#     [root@po16846vm linux-powerpc]# size -x vmlinux
#        text    data     bss     dec     hex filename
#     0x111019c       0x41b0d4        0x490de0        26984528        19bc050 vmlinux
#     
#     This patch maps up to 32 Mbytes code based on _einittext symbol
#     and allows 32 Mbytes of memory instead of 24.
