Pull RISC-V updates from Palmer Dabbelt: "This contains a handful of patches for this merge window: - Support for kasan - 32-bit physical addresses on rv32i-based systems - Support for CONFIG_DEBUG_VIRTUAL - DT entry for the FU540 GPIO controller, which has recently had a device driver merged These boot a buildroot-based system on QEMU's virt board for me" * tag 'riscv-for-linus-5.6-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: dts: Add DT support for SiFive FU540 GPIO driver riscv: mm: add support for CONFIG_DEBUG_VIRTUAL riscv: keep 32-bit kernel to 32-bit phys_addr_t kasan: Add riscv to KASAN documentation. riscv: Add KASAN support kasan: No KASAN's memmove check if archs don't have it.
