This change does two things: Copy-pastes "retint_swapgs:" code into syscall handling code, the copy is under "syscall_return:" label. The code is unchanged apart from some label renames. Removes "opportunistic sysret" code from "retint_swapgs:" code block, since now it won't be reached by syscall return. This in fact removes most of the code in question. text data bss dec hex filename 12530 0 0 12530 30f2 entry_64.o.before 12562 0 0 12562 3112 entry_64.o Run-tested.
