Component Type: kbuild config

Description: 52-bit

More info: Enable 52-bit virtual addressing for userspace when explicitly requested via a hint to mmap(). The kernel will also use 52-bit virtual addresses for its own mappings (provided HW support for this feature is available, otherwise it reverts to 48-bit). NOTE: Enabling 52-bit virtual addressing in conjunction with ARMv8.3 Pointer Authentication will result in the PAC being reduced from 7 bits to 3 bits, which may have a significant impact on its susceptibility to brute-force attacks. If unsure, select 48-bit virtual addressing instead.
