Subject: [PATCH v3 0/2] Improve KASAN_VMALLOC support 

This patchset improves KASAN vmalloc implementation by fixing an
oversight where kernel page table was not flushed in patch 1 and by
reworking the kernel page table PGD level population in patch 2.

Changes in v3:
- Split into 2 patches
- Add reviewed-by

Changes in v2:
- Quiet kernel test robot warnings about missing prototypes by declaring
  the introduced functions as static.

Alexandre Ghiti (2):
  riscv: Ensure page table writes are flushed when initializing KASAN
    vmalloc
  riscv: Cleanup KASAN_VMALLOC support
