Lai Jiangshan 0aca53c6b5 x86/traps: Use pt_regs directly in fixup_bad_iret() ... Always stash the address error_entry() is going to return to, in %r12 and get rid of the void *error_entry_ret; slot in struct bad_iret_stack which was supposed to account for it and pt_regs pushed on the stack. After this, both fixup_bad_iret() and sync_regs() can work on a struct pt_regs pointer directly.
