New eyes are looking over ancient code and comments which were put
in as the design was first coming together... and which don't make
even the slightest bit of sense any more.

This allows for MTD support to be used on flash memory which is also used
for XIP purposes, either XIP kernel or XIP userspace.  The whole idea is
to relocate functions actually modifying the flash state away from array mode
to ram and run them with interrupt disabled.  When the flash needs some time
to complete a certain operation, we poll the processor for pending (but still
masked) interrupts, and when they occur we suspend the flash operation in order
to unmask interrupts and let the system run again.

Problem reported by Gerd Knorr:

  (1) boot with vesafb (thats what I'm using, maybe it shows on other
      framebuffers and/or vgacon as well).
  (2) login into one terminal, then type "echo -ne '\033[?17;15;239c'".
      You should have a nice, yellow and *not* blinking cursor block.
      That is what I have in my .profile because I can't stand the
      blinking cursors.
  (3) Switch to another terminal.  The cursor goes into blinking
      underscore mode now (i.e. the default cursor).
  (4) Switch back to the first terminal.  Now you have a yellow block
      with the last two pixel lines (i.e. the underscore) blinking.

This bug is caused by both fbcon_cursor and vt softcursor being active at
the same time.

Fix:

- Disable fbcon_cursor if vt softcursor is active (vc->vc_cursor_type &
  0x10) != 0.

- Recheck/reload fbcon cursor for each vt switch
