ruby-2.6.13-A0

[Aivils S. <ai...@un...>]

Hi, All!

	This is synced to 2.6.13 Linux kernel release. A0 - internal
version number.
http://www.ltn.lv/~aivils/files/ruby-2.6.13-A0.diff.bz2

It continues reduction line of Zoltan Boszormenyi. Possibly
contains only few empty patches. Stil very big anyway. It
created against 2.6.13 in hope to trap some tester. --mm
tree will not boot or run sometimes.

Tested: fbcon signle head, dummycon multi head.
gpm untested. /dev/vcs* untested.

Bugs:
tex mode: On Alt-F2 show blank screen or lost cursor.Restore
screen on Enter press.

uses ruby VT handler
---------------------
keyboard 1 --> head 1
keyboard 2 --> head 2
...
keyboard N --> head N

head 1 uses all beepers
head 2 uses all beepers
...
head N uses all beepers

Seems is necessary add to user interface via /proc beeper
maping code.

Unfortunately before merging with -mm linux-ruby must be
100% backward compatible. All keyboards must be maped to
1st console. Fbcon must be capable to use any VC in mess
order. Any TTY uses all system beepers. User interface
must be capable show weird mapping like keyboard 1,2,3 to
VT1 and keyboard 3,5,8 to VT2, beeper3 to VT1.

Spliting ruby to small pieces is big job too.
