------------------------------------------------------
Subject: powerpc: invalid size for swapper_pg_dir with CONFIG_PTE_64BIT=y
From: "Cedric Hombourger" <chombourger@xxxxxxxxx>
The size of swapper_pg_dir is 8k instead of 4k when using 64-bit PTEs
(CONFIG_PTE_64BIT). Checked by printing the size of this variable from C
code. Kernel successfuly transferred control to init with this change
while it was crashing in map_page() before.
