Detailed Description

Where a thread goes on in the kernel when it runs again: the registers that a function call keeps (AAPCS64: x19 to x29, and the link register), and the stack pointer.

aarch64_ctx_save() saves them and returns 0; aarch64_ctx_load() later returns from that same call again, this time with 1 (as setjmp() and longjmp() do).
