From be79afc740b5a1b2048cd67580cdb9d76d7e6cc2 Mon Sep 17 00:00:00 2001 From: Liu Shixin Date: Wed, 12 Oct 2022 20:00:38 +0800 Subject: [PATCH] riscv: Enable HAVE_ARCH_HUGE_VMALLOC for 64BIT MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit After we support HAVE_ARCH_HUGE_VMAP, we can now enable HAVE_ARCH_HUGE_VMALLOC too. This feature has been used in kvmalloc and alloc_large_system_hash for now. This feature can be disabled by kernel parameters "nohugevmalloc".
