commit 4f115596133fa168bac06bb34c6efd8f4d84c22e upstream.
The commit
f9aad622006bd64c ("mm: rename GENERIC_PTDUMP and PTDUMP_CORE")
has broken PTDUMP and the Kconfig options that use it on ARCH=i386, including CONFIG_DEBUG_WX.
CONFIG_GENERIC_PTDUMP was renamed into CONFIG_ARCH_HAS_PTDUMP, but it was mistakenly moved from "config X86" to "config X86_64". That made PTDUMP unavailable for i386.
Move CONFIG_ARCH_HAS_PTDUMP back to "config X86" to fix it.
