[patch 0/3] ps3fb updates

From: <hidden>
Date: 2007-07-20 13:05:55

	Hi,

Here are a few updates for the PS3 frame buffer device:
  [1] ps3fb: Enable VT_HW_CONSOLE_BINDING for proper kexec
  [2] ps3fb: Shrink default virtual frame buffer size from 18 to 9 MiB
  [3] ps3fb: Set FBINFO_READS_FAST to speed up text console scrolling

The first one allows to do a proper reboot or kexec and depends on
cfafca8067c6defbaeb28cb898b7b3f8abdfe20d, which went in recently.

The last two are minor trivial changes.

With kind regards,

[patch 1/3] ps3fb: Enable VT_HW_CONSOLE_BINDING for proper kexec

From: <hidden>
Date: 2007-07-20 13:05:55

From: Geert Uytterhoeven <redacted>

ps3fb: VT_HW_CONSOLE_BINDING must be enabled to make console unbinding work,
which is needed to give up all hypervisor resources before reboot or kexec.

[patch 2/3] ps3fb: Shrink default virtual frame buffer size from 18 to 9 MiB

From: <hidden>
Date: 2007-07-20 13:05:55

From: Geert Uytterhoeven <redacted>

ps3fb: Shrink the default virtual frame buffer size from 18 to 9 MiB, as
nobody really uses the double buffering feature and Linux can use an
additional 9 MiB. It can still be overridden on the kernel command line
using `ps3fb=18M'.
