Prev: [RFC PATCH 2/3] ARM: Mark CPU_32v6K as depended on CPU_V7
Next: [RFC PATCH 1/3] kbuild: Warn on selecting symbols with unmet direct dependencies
From: Catalin Marinas on 8 Jun 2010 12:30
DEBUG_PAGEALLOC currently depends on ARCH_SUPPORTS_DEBUG_PAGEALLOC.
However, it is selected by PAGE_POISONING which depends on
!ARCH_SUPPORTS_DEBUG_PAGEALLOC.

This patch changes the DEBUG_PAGEALLOC entry so that the dependency is
moved to the definition line rather than having an explicit "depends on"
line.
