Subject: mm: debug-pagealloc: fix kconfig dependency warning
From: Akinobu Mita <akinobu.mita@xxxxxxxxx>
Fix kconfig dependency warning to satisfy dependencies:
warning: (PAGE_POISONING) selects DEBUG_PAGEALLOC which has unmet
direct dependencies (DEBUG_KERNEL && ARCH_SUPPORTS_DEBUG_PAGEALLOC &&
(!HIBERNATION || !PPC && !SPARC) && !KMEMCHECK)

Unmap pages from the kernel linear mapping after free_pages().
This results in a large slowdown, but helps to find certain types
of memory corruption.
+ For architectures which don't enable ARCH_SUPPORTS_DEBUG_PAGEALLOC,
+ fill the pages with poison patterns after free_pages() and verify
+ the patterns before alloc_pages(). Additionally,
+ this option cannot be enabled in combination with hibernation as
+ that would result in incorrect warnings of memory corruption after
+ a resume because free pages are not saved to the suspend image.
