[PATCH 11/15] x86/kconfig/64: Enable popular MM options in the defconfig

[Ingo Molnar]

Since the x86 defconfig aims to be a distro kernel work-alike with
fewer drivers and a shorter build time, enable the following
MM options that are typically enabled on major Linux distributions:

- ACPI_HOTPLUG_MEMORY, ZSWAP, SLAB hardening, MEMORY_HOTPLUG,
  MEMORY_HOTREMOVE, PAGE_REPORTING, KSM, higher DEFAULT_MMAP_MIN_ADDR,
  MEMORY_FAILURE, HWPOISON_INJECT, TRANSPARENT_HUGEPAGE,
  TRANSPARENT_HUGEPAGE_MADVISE, IDLE_PAGE_TRACKING, ZONE_DEVICE
  DEVICE_PRIVATE, ANON_VMA_NAME, USERFAULTFD, multi-gen LRU.
