The Svrsw60t59b extension allows to free the PTE reserved bits 60 and 59 for software to use. Reviewed-by: Alexandre Ghiti <alexghiti@rivosinc.com> Signed-off-by: Chunyan Zhang <zhangchunyan@iscas.ac.cn> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>
The Svrsw60t59b extension allows to free the PTE reserved bits 60 and 59 for software, this patch uses bit 59 for soft-dirty. To add swap PTE soft-dirty tracking, we borrow bit 3 which is available for swap PTEs on RISC-V systems.

The Svrsw60t59b extension allows to free the PTE reserved bits 60 and 59 for software, this patch uses bit 60 for uffd-wp tracking Additionally for tracking the uffd-wp state as a PTE swap bit, we borrow bit 4 which is not involved into swap entry computation.
