Merge tag 'riscv-for-linus-5.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt:
"This contains a handful of fixes that I would like to target for 5.6:
- A pair of fixes to module loading, which we hope solve the last of
the issues with module text being loaded too sparsely for our call
relocations.
- A Kconfig fix that disallows selecting memory models not supported
by NOMMU.
- A series of Kconfig updates to ease selecting the drivers necessary
to run on QEMU's virt platform.
- DTS updates for SiFive's HiFive Unleashed.
- A fix to our seccomp support that avoids mangling restartable
syscalls"
