It is not so difficult as it looks. The master pgd looking as:
.org 0x1000 ENTRY(swapper_pg_dir) .long 0x00102007 .long 0x00103007 .fill BOOT_USER_PGD_PTRS-2,4,0 /* default: 766 entries */ .long 0x00102007 .long 0x00103007 /* default: 254 entries */ .fill BOOT_KERNEL_PGD_PTRS-2,4,0
should become:
.org 0x1000 ENTRY(swapper_pg_dir) .long 0x00102007 .long 0x00103007 .... # every entry addresses 4 MB exactly .... # so add as much as you want .long 0x0010X007 .fill BOOT_USER_PGD_PTRS-X+2,4,0 /* default: 766-X entries */ .long 0x00102007 .long 0x00103007 .... # every entry addresses 4 MB exactly .... # so add as much as you want /* default: 254-X entries */ .fill BOOT_KERNEL_PGD_PTRS-X+2,4,0
empty_zero_page, empty_bad_page, etc... offsets should be also appropriately changed and the corresponding code in mm init as well.
But i honestly don't see the point of all that.
