Merge tag 'riscv-for-linus-5.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt: - A build fix to always build modules with the 'medany' code model, as the module loader doesn't support 'medlow'. - A Kconfig warning fix for the SiFive errata. - A pair of fixes that for regressions to the recent memory layout changes. - A fix for the FU740 device tree. * tag 'riscv-for-linus-5.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: dts: fu740: fix cache-controller interrupts riscv: Ensure BPF_JIT_REGION_START aligned with PMD size riscv: kasan: Fix MODULES_VADDR evaluation due to local variables' name riscv: sifive: fix Kconfig errata warning riscv32: Use medany C model for modules
