The Linux NVDIMM PEM drivers require arch support to map and access the persistent memory device. This series adds RISC-V PMEM support using recently added Svpbmt and Zicbom support.
First two patches are fixes and remaining two patches add the required PMEM support for Linux RISC-V.
These patches can also be found in riscv_pmem_v6 branch at: https://github.com/avpatel/linux.git
Changes since v5: - Rebased on Linux-6.1-rc5 - Directly add pmem.o in obj-y of PATCH3 - Dropped PATCH1 since this is already merged.
Changes since v4: - Simplify PATCH2 by implementing RISC-V specific arch_memremap_wb()
Changes since v3: - Pickup correct version of Drew's patch as PATCH1
Changes since v2: - Rebased on Linux-6.1-rc1 - Replaced PATCH1 with the patch proposed by Drew
Changes since v1: - Fix error reported by test bot https://lore.kernel.org/all/202208272028.IwrNZ0Ur-lkp@intel.com/
