Subject: [PATCH] kbd: (#7063) make CapsLock work as expected even for
 non-ASCII

Steps to reproduce:

	[log into console (not xterm)]
	[load non-trivial keymap]
	[turn on CapsLock]
	[type something]

Symbols won't be capital despite CapsLock and despite Shift+* working
as expected.

Note: patch relies on keymap being consistent wrt SMALL/CAPITAL symbols.
Though extracting SMALL <=> CAPITAL mapping from unicode tables and
putting it into kernel may be more correct.

Fix long-standing http://bugzilla.kernel.org/show_bug.cgi?id=7063
