Alexandre Ghiti 25abe0db92 riscv: Fix kfence now that the linear mapping can be backed by PUD/P4D/PGD 
RISC-V Kfence implementation used to rely on the fact the linear mapping
was backed by at most PMD hugepages, which is not true anymore since
commit 3335068f87 ("riscv: Use PUD/P4D/PGD pages for the linear
mapping").

Instead of splitting PUD/P4D/PGD mappings afterwards, directly map the
kfence pool region using PTE mappings by allocating this region before
setup_vm_final().

Closes: https://syzkaller.appspot.com/bug?extid=a74d57bddabbedd75135
