Subject: mm: hugetlb_vmemmap: replace early_param() with core_param()
Date: Tue, 28 Jun 2022 17:22:32 +0800
After the following commit:
78f39084b41d ("mm: hugetlb_vmemmap: add hugetlb_optimize_vmemmap sysctl")
There is no order requirement between the parameter of
"hugetlb_free_vmemmap" and "hugepages" since we have removed the check of
whether HVO is enabled from hugetlb_vmemmap_init(). Therefore we can
safely replace early_param() with core_param() to simplify the code.
