074f98df05 sh: Add 32-bit opcode feature CPU flag.
Add a CPU flag for the CPUs that support 32-bit opcodes, which
gets passed down to userspace.

53f983a90d sh: Fix PC adjustments for varying opcode length.
There are a few different cases for figuring out how to
size the instruction. We read in the instruction located
at regs->pc - 4 when rewinding the opcode to figure out if
there's a 32-bit opcode before the faulting instruction, with
a default of a - 2 adjustment on a mismatch. In practice this
works for the cases where pc - 4 is just another 16-bit opcode,
or we happen to have a 32-bit and a 16-bit immediately
preceeding the pc value.

In the cases where we aren't rewinding, this is much less ugly..

We also don't bother fixing up the places where we're explicitly
dealing with 16-bit instructions, since this might lead to
confusion regarding the encoding size possibilities on other
CPU variants.

bd0799977c sh: Support for SH-2A 32-bit opcodes.

hardcoded 16-bit assumptions.

00bf0610e4 sh: Share exception vector table for SH-3/4.
The only difference between these at the moment are the FPU
exceptions, and these are hidden away under CONFIG_SH_FPU
(which is only set for the SH-4 case anyways..).

This consolidates the two tables, and updates SH-4 to use
the updated copy.

Previously this was only set when CONFIG_BUG=y. While we rely

2ae8547775 vgacon: disallow console operations when in KD_GRAPHICS mode
Reported by James Pearson as:

	 boot to run level 3

	 if not root, then make sure /dev/console is writeable

	 login and type:

	 setterm -blank 0

	 start X

	 type into an xterm:

	 while true; do echo "" > /dev/console; usleep 100000; done

	 while the above loop is running switch to the text console and back
	 again (Ctrl-Alt-F1 then Ctrl-Alt-F7)

	 ... and the screen will be shifting (and wrapping) to the left.

This problem stems from continuously writing text to the system console (which
is in KD_TEXT mode) while the foreground console is in KD_GRAPHICS
mode. Somewhere along the way, console printing got confused and omitted the
KD_GRAPHICS/KD_TEXT test.  Thus, vgacon attempted to scroll the screen of X,
which causes X to shift.

Fix by disallowing vgacon to touch the hardware when the vc is in KD_GRAPHICS
mode. A definitive fix entails a full audit of the console code.

0449359f05 vga: vgastate fix
1) sets 'palette access disabled' during read from AR10.
   This is usually documented as needed for access AR01-AR0F,
   but on ARK Logic card it is needed for AR10 (otherwise read
   returns some nonsence and save_vga_text() returns before do
   anything).

2) do not restore AR10, because it was not changed during

3) remove modification of misc reg:
        /* force graphics mode */
        vga_w(state->vgabase, VGA_MIS_W, misc | 1);

   as comment is misleading - LSB of misc reg does not set/reset graphics
   mode, but set color/mono adresses of CRT and some other regs.
   but these regs are not used during save/restore fonts.
   (it worked even when (misc | 1) was replaced by (misc & ~1) ).

56c7554938 s3fb: implement fb_get_caps
Implement fb_get_caps().  This will allow the driver to tell upper layer that
it can only support 256 8x16 bitmaps when in tileblitting mode
(var->bits_per_pixel == 0);

38a3dc5185 fbdev: fbcon: check if mode can handle new screen
Check if the mode can properly display the screen.  This will be needed by
drivers where the capability is not constant with each mode.  The function
fb_set_var() will query fbcon the requirement, then it will query the driver
(via a new hook fb_get_caps()) its capability.  If the driver's capability
cannot handle fbcon's requirement, then fb_set_var() will fail.

For example, if a particular driver supports 2 modes where:

mode1 = can only display 8x16 bitmaps
mode2 = can display any bitmap

then if current mode = mode2 and current font = 12x22

fbset <mode1> /* mode1 cannot handle 12x22 */
fbset will fail

e15de77e74 nvidiafb: prevent triggering of softlockup
If the chip locks up, we get into a long polling loop,
where the softlockup detector kicks in.
See https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=151878
for an example.

[adaplas]
Chip lockup can occur at 3 points (flush, sync, and wait). Consolidate and
allow the driver to go to safe mode cleanly.

d4a96b5312 pm2fb: pixclock setting restriction
This patch adds restrictions to calculations of m, n and p factors
which sets the pixclock for the Permedia 2V. I found during tests
that synchronization is unstable if m (divisor) is bigger than
half of the n (numerator). The patch disallows such settings
combination.
