Konstantin Belousov 1947b29861 amd64: Streamline exceptions and interrupts handlers. ... PTI-mode entry points were coded to set up the environment identical to non-PTI entry and then fall-through to non-PTI handlers, mostly. This has the drawback of requiring two more SWAPGS, first to access PCPU, and then to return to the state expected by the non-PTI entry point. Eliminate the duplication by doing more in entry stubs both for PTI and non-PTI, and adjusting the common code to expect that SWAPGS and some minimal registers saving is done by entries. Some less often used entries, in particular, #GP, #NP, and #SS, which can fault on doreti, are left as is because there are basically four variants of entrance, and they are not performance-critical, esp. comparing with e.g. #PF or interrupts.
