81a797373f Fix minilua vararg stack handling. 
Note: this is not exploitable! minilua is only used during the LuaJIT
build process. It only runs controlled and static Lua code (DynASM),
which is entirely contained within this repo. LuaJIT itself has
completely different stack handling code and is not affected either.

This change is solely for the benefit of others, who might possibly use
minilua for purposes other than running DynASM.

67dbec82f4 Linux/ARM64: Make mremap() non-moving due to VA space woes. 
This reduces overall performance on ARM64, but we have no choice.
Linux kernel default userspace VA is 48 bit, but we'd need 47 bit.
mremap() ignores address hints due to a kernel API issue. The mapping
may move to an undesired address which will cause an assert or crash.
