Selecting 13 or 15 will lead to a compile-time error "Unsupported PAGE_SIZE"
(in include/asm/ppc_page_asm.h), so users will not be able to run kernel with
PAGE_SIZE different than 4K, 16K or 64K anyway.
Do you think that replacing one integer option CONFIG_PPC_PAGE_SHIFT with
three logical options (i.e., CONFIG_PPC_PAGE_SIZE_4K,
CONFIG_PPC_PAGE_SIZE_16K and CONFIG_PPC_PAGE_SIZE_64K) will be the better
choice ?
Regards, Yuri.
