      console: consume APC, DM, DCS · 3a2b2eb5
      nick black authored
      The Linux console's VT102 implementation already consumes OSC
      ("Operating System Command") sequences, probably because that's how
      palette changes are transmitted.
      
      In addition to OSC, there are three other major clases of ANSI control
      strings: APC ("Application Program Command"), PM ("Privacy Message"),
      and DCS ("Device Control String").  They are handled similarly to OSC in
      terms of termination.
      
      Source: vt100.net
      
      Add three new enumerated states, one for each of these types.  All three
      are handled the same way right now--they simply consume input until
      terminated.  I hope to expand upon this firmament in the future.  Add
      new predicate ansi_control_string(), returning true for any of these
      states.  Replace explicit checks against ESosc with calls to this
      function.  Transition to these states appropriately from the escape
      initiation (ESesc) state.
      
      This was motivated by the following Notcurses bugs:
      
       https://github.com/dankamongmen/notcurses/issues/2050
       https://github.com/dankamongmen/notcurses/issues/1828
       https://github.com/dankamongmen/notcurses/issues/2069
      
      where standard VT sequences are not consumed by the Linux console.  It's
      not necessary that the Linux console *support* these sequences, but it
      ought *consume* these well-specified classes of sequences.
      
      Tested by sending a variety of escape sequences to the console, and
      verifying that they still worked, or were now properly consumed.
      Verified that the escapes were properly terminated at a generic level.
      Verified that the Notcurses tools continued to show expected output on
      the Linux console, except now without escape bleedthrough.

      string: improve default out-of-line memcmp() implementation · 291d47cc
      Linus Torvalds authored
      This just does the "if the architecture does efficient unaligned
      handling, start the memcmp using 'unsigned long' accesses", since
      Nikolay Borisov found a load that cares.
      
      This is basically the minimal patch, and limited to architectures that
      are known to not have slow unaligned handling.  We've had the stupid
      byte-at-a-time version forever, and nobody has ever even noticed before,
      so let's keep the fix minimal.
      
      A potential further improvement would be to align one of the sources in
      order to at least minimize unaligned cases, but the only real case of
      bigger memcmp() users seems to be the FIDEDUPERANGE ioctl().  As David
      Sterba says, the dedupe ioctl is typically called on ranges spanning
      many pages so the common case will all be page-aligned anyway.
      
      All the relevant architectures select HAVE_EFFICIENT_UNALIGNED_ACCESS,
      so I'm not going to worry about the combination of a very rare use-case
      and a rare architecture until somebody actually hits it.  Particularly
      since Nikolay also tested the more complex patch with extra alignment
      handling code, and it only added overhead.
