Hello, Peter.

I have another version of the patch which makes GPM usable on scrolled
consoles.  I'd like to think that it's now final.

OK, I'm enclosing a patch for each version, 5.15.x and 6.1.y.  I'm not
aware of any outstanding bugs in these patches.  In particular, the
following have been fixed since the previous version:
(i) The synchronisation between the "mouse" character buffer and the
  contents of the screen is now 100%.  In particular, when changing
  fonts (e.g. at bootup), and when the Tux logos get removed from the
  screen, things continue working.
(ii) CONFIG_LOGO (i.e. the Tuxes on bootup) can now be freely configured
  without losing functionality.

Just a quick reminder of how to use these files for anybody else who
might be interested:
(i) cd /usr/src/linux-5.15.88-gentoo, or similar.  (Or
  ...-6.1.x-gentoo).
(ii) patch -p1 < 5.15.80-GPM.20230203.diff (or the other one).
(iii) Configure the kernel as normal.  Additionally, under Device
  drivers/Graphic Support/Console display driver support, enable
  CONFIG_FRAMEBUFFER_CONSOLE_SOFT_SCROLLBACK, set the buffer size to
  taste (it's default is 128 kB) and accept the default enablement of
  CONFIG_FRAMEBUFFER_CONSOLE_SOFT_SCROLLBACK_GPM.
(iv) Build the kernel and install it into your boot manager.
(v) Reboot and enjoy!  You can now use GPM in scrolled consoles.
