arm64: mm: Introduce MAX_USER_VA_BITS definition With the introduction of 52-bit virtual addressing for userspace, we are now in a position where the virtual addressing capability of userspace may exceed that of the kernel. Consequently, the VA_BITS definition cannot be used blindly, since it reflects only the size of kernel virtual addresses. This patch introduces MAX_USER_VA_BITS which is either VA_BITS or 52 depending on whether 52-bit virtual addressing has been configured at build time, removing a few places where the 52 is open-coded based on explicit CONFIG_ guards.
