Merge tag 'riscv-for-linus-5.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt:
"I've collected a handful of fixes over the past few weeks:
- A fix to un-break the build-id argument to the vDSO build, which is
necessary for the LLVM linker.
- A fix to initialize the jump label subsystem, without which it (and
all the stuff that uses it) doesn't actually function.
- A fix to include <asm/barrier.h> from <vdso/processor.h>, without
which some drivers won't compile"
