CONFIG_X86_PAE

Use PAE page tables

Type: bool

Help

If enabled, use PAE-style page tables instead of 32-bit page tables.
The advantage is support for the Execute Disable bit, at a cost of
more memory for paging structures.

Direct dependencies

X86_MMU && !X86_64 && X86

(Includes any dependencies from ifs and menus.)
