Subject: [PATCH v2 2/2] riscv: Enable HAVE_ARCH_HUGE_VMALLOC for 64BIT
Date: Sat, 8 Oct 2022 22:05:06 +0800	[thread overview]
Message-ID: <20221008140506.1066805-3-liushixin2@huawei.com> (raw)
In-Reply-To: <20221008140506.1066805-1-liushixin2@huawei.com>

After we support HAVE_ARCH_HUGE_VMAP, we can now enbale 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".
