It especially cannot have the same live AR windows as the parent, otherwise it will overwrite the parent stack on overflow, likely causing corruption. (and so it did...) Effectively, the register windows need to be spilled. Turns out it's much easier to simply not copy parent register windows when CLONE_VM is set.

2001 From: Max Filippov Date: Mon, 15 Oct 2012 03:55:41 +0400 Subject: xtensa: Use Kbuild infrastructure to handle asm-generic headers Use Kbuild infrastructure to handle the asm-generic headers and remove the wrapper headers that call them. This only affects headers that do nothing but include the generic equivalent. It does not touch any header that does a little more.

This usually requires to include uapi/unistd.h twice. Instead of removing the guard agains multiple inclusion entirely, allow to include unistd.h again only if __SYSCALL is defined.
