linux-stable.git/arch/riscv/include/asm/vmalloc.h, branch linux-6.3.y Linux kernel stable tree riscv: Enable HAVE_ARCH_HUGE_VMAP for 64BIT 2022-10-29T00:10:01+00:00 Liu Shixin liushixin2@huawei.com 2022-10-12T12:00:37+00:00 310f541a027b1d5dc68f44f176cde618e6ee9691 This sets the HAVE_ARCH_HUGE_VMAP option, and defines the required page table functions. With this feature, ioremap area will be mapped with huge page granularity according to its actual size. This feature can be disabled by kernel parameter "nohugeiomap".
