Hi Linus,

This enables the percpu page allocator for risc-v as a fallback path.

Separately, I just sent out a respin of Thomas' cpu hotplug related fixes
for percpu_counters in [1]. I'll hopefully pull that in shortly and get
it into for-next for some wider testing.

Thanks,
Dennis

  riscv: Enable pcpu page first chunk allocator (2023-12-14 00:24:06 -0800)

----------------------------------------------------------------
percpu:
- Enable percpu page allocator for risc-v. There are risc-v
  configurations with sparse NUMA configurations and small vmalloc
  space causing dynamic percpu allocations to fail as the backing chunk
  stride is too far apart.
