The Kconfig text for CONFIG_DEBUG_SLAB and CONFIG_DEBUG_PAGEALLOC have always seemed a bit confusing. Change them to: CONFIG_DEBUG_SLAB: "Debug slab memory allocations" CONFIG_DEBUG_PAGEALLOC: "Debug page memory allocations" Cc: "David S.

Unmap pages from the kernel linear mapping after free_pages().

of memory corruptions.
