From 350e88bad4964da6feabee02a1a70381bcdb087e Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Mon, 13 May 2019 17:22:59 -0700 Subject: mm: memblock: make keeping memblock memory opt-in rather than opt-out Most architectures do not need the memblock memory after the page allocator is initialized, but only few enable ARCH_DISCARD_MEMBLOCK in the arch Kconfig. Replacing ARCH_DISCARD_MEMBLOCK with ARCH_KEEP_MEMBLOCK and inverting the logic makes it clear which architectures actually use memblock after system initialization and skips the necessity to add ARCH_DISCARD_MEMBLOCK to the architectures that are still missing that option.
