Merge patch series "riscv: Increase mmap_rnd_bits_max on Sv48/57"
Sami Tolvanen <samitolvanen@google.com> says:
We noticed that 64-bit RISC-V kernels limit mmap_rnd_bits to 24
even if the hardware supports a larger virtual address space size
[1]. These two patches allow mmap_rnd_bits_max to be changed during
init, and bumps up the maximum randomness if we end up setting up
4/5-level paging at boot.
* b4-shazam-merge:
riscv: mm: Update mmap_rnd_bits_max
mm: Change mmap_rnd_bits_max to __ro_after_init
