	fbcon internal cleanup.  Instead of passing console_font_op into
fbcon_do_set_font() we pass width/height directly.  Amusing (but harmless)
bug fixed there:
	if (!w > 32) {
		bogus code that fortunately never got triggered
	}
Fixed by removal of the junk in question (and yes, it's verifiable junk -
it would not do anything even if we replaced the check with intended
!(w > 32)).

con_font_set() sanitized.  We are passing console_font and flags into
the method in separate arguments and we are not messing with
console_font_op->data anymore - it's a userland pointer (to be annotated
several patches later in the series, due to another abuse of console_font_op
that needs to be fixed first), while console_font->data is kernel one
and they don't mix anymore.

We also do a sanity check (font width > 0) in the caller instead of
method instances, since we are already checking for width <= 32 and
height <= 32 there; doesn't make sense leaving that one in method
instances.

->con_font_copy() sanitized.  We extract the number of console to copy the
font from in the caller (it's taken from the field of console_font_op that
is normally used for font height - messy even for an ioctl, but that animal
used to be passed all the way down into console drivers).

With decoding done in con_font_copy(), we simply pass source console number
into the method.

Preparations for cleanups: con_font_op() is turned into a switch calling
con_font_{get,set,default,copy} depending on the operation required;
method ->con_font_op() also split, with NULL resulting in -ENOSYS on
operation in question.

Code that used to be in con_font_op() got slightly cleaned up after move
into new helpers (we are beginning to untangle the mess; there will be
more cleanups in the next patches).

Methods are currently using exact same arguments as old ->con_font_op().
That will change in subsequent patches, method by method (right now there's
a hell of a scary field reuse between them, making impossible to do any
static checks and practically begging for bugs).

The ppc64 implementation of memcpy_to/from_io was bogus (used memcpy
which uses cache hints and thus is broken on non cacheable IO space).

This re-implements them with some simple/gross C code doing 32 bits

I think I understood why some ext2 fs corruption still happens even after
the last i_size fix.

what happened I believe is that the writepages layer got a not a fully
uptodate page (in turn with bh mapped on top of it), and then right before
unlocking the page and entering the writeback mode, it freed all the bh.
Without bh a not uptodate page will trigger a full readpage from disk, that
overwrites the pagecache before the multi-bio gets submitted, generating fs
corruption.

I believe the below patch should fix it (untested) against kernel CVS.

The testcases developed by Kurt showed the pagecache being overwritten with
on-disk data at block offsets, and Chris as well was wondering about races
between wait_on_page_writeback and readpage.  the below fix just explains
everything we've seen since not-fully-uptodate pages must have always bh on
them and the below patch enforces just that invariant, and it should fix
our pagecache-overwritten-by-disk-data problem.
