The code attempts to enable them, but hits an undefined behaviour by
shifting by the entire register's width:
int lines = 32;
u32 mask = (1 << lines) - 1; // 00000000 on x86
u32 mask = (1 << lines) - 1; // ffffffff on arm (32)
u32 mask = (1 << lines) - 1; // 00000000 on arm64
u32 mask = (1ULL << lines) - 1; // ffffffff everywhere
