This patchset intends to improve tlb utilization by using hugepages for
the linear mapping.
v5:
- Fix nommu builds by getting rid of riscv_pfn_base in patch 1, thanks
Conor
- Add RB from Andre
v4:
- Rebase on top of v6.2-rc3, as noted by Conor
- Add Acked-by Rob
v3:
- Change the comment about initrd_start VA conversion so that it fits
ARM64 and RISCV64 (and others in the future if needed), as suggested
by Rob
v2:
- Add a comment on why RISCV64 does not need to set initrd_start/end that
early in the boot process, as asked by Rob
