[PATCH 0/3] x86: Fix pt_regs passed by value

[Brian Gerst]

Several syscalls and one trap handler currently rely on the pt_regs
struct being passed in by value.  This causes problems with stack
protector, and can also cause problems with corruption due to tail-call
optimization.  Change them to use a pointer to the pt_regs struct
instead.
