Subject: [PATCH v3 2/2] riscv: Enable HAVE_ARCH_HUGE_VMALLOC for 64BIT
Date: Wed, 12 Oct 2022 20:00:38 +0800	[thread overview]
Message-ID: <20221012120038.1034354-3-liushixin2@huawei.com> (raw)
In-Reply-To: <20221012120038.1034354-1-liushixin2@huawei.com>

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".
