Userspace VAs

--------------------

To maintain compatibility with software that relies on the VA space with a

maximum of 48 bits the kernel will, by default, return virtual addresses to

userspace from a 48-bit range (sv48). This default behavior is achieved by

passing 0 into the hint address parameter of mmap. On CPUs with an address space

smaller than sv48, the CPU maximum supported address space will be the default.



Software can "opt-in" to receiving VAs from another VA space by providing

a hint address to mmap. When a hint address is passed to mmap, the returned

address will never use more bits than the hint address. For example, if a hint

address of `1 << 40` is passed to mmap, a valid returned address will never use

bits 41 through 63. If no mappable addresses are available in that range, mmap

will return `MAP_FAILED`.
