99e11ab20b macfb: fix 24-bit visual and stuff
Lots of changes. Remove volatile keywords. Take the advice in the comments
and change video_slot to slot_addr. Factor out fifteen or so "channel >>
8" shifts into three shifts higher up the call graph. Make
csc_setpalette() atomic, pass the correct color values. Check for
ioremap() failure. Add missing break statement, thus fixing 24 bit console
visual (blue background bug). Remove some uninformative printk() noise.
Add a description for powerbook 140/170 graphics.

11e8faca2e valkyriefb: various fixes
Valkyriefb and macfb will adopt the same card if they get the chance, so
remove valkyrie support from macfb. Also fix the "valkyriefb: can't do
832x624x8" problem reported by Raylynn Knight some time ago, by adding
vmode 13 support for CONFIG_MAC. Also add vmode 11 since that works too.
Make use of the monitor sense lines on 68k Macs too. Also some cleanups.

d876c11a0f fbdev: mac_var_to_mode() fix
The valkyriefb driver assumes that this logic holds:

mac_vmode_to_var(X, cmode, &var);
mac_var_to_vmode(&var, &vmode, &cmode);
assert(vmode == X);

But it doesn't hold because mac_var_to_vmode() can return a mode with a
slower pixel clock, even when a match is available. So we end up with this
failure:

using video mode 11 and color mode 0.
valkyriefb: vmode 12 not valid.
valkyriefb: can't set default video mode
valkyriefb: vmode 12 not valid.

Rather than have mac_var_to_mode() return the first reasonable mode it
finds, have it return the mode that is closest to the requested one (or
the mode with the closest longer pixel clock period if there is no exact
match).

7bdda6209f sh: Fix up more 64-bit pgprot truncation on SH-X2 TLB.
Both the store queue API and the PMB remapping take unsigned long for
their pgprot flags, which cuts off the extended protection bits. In the
case of the PMB this isn't really a problem since the cache attribute
bits that we care about are all in the lower 32-bits, but we do it just
to be safe. The store queue remapping on the other hand depends on the
extended prot bits for enabling userspace access to the mappings.

92e1f9a7ed video: sh_mobile_lcdcfb: Fix panning.
Fixed SH-Mobile panning. Previously the address of the frame to be displayed
was updated in the VSync end interrupt. This meant there was a minimum of 1
frame bewteen calling FBIOPAN_DISPLAY ioctl and the pan occuring. This meant
that apps were not able to use the FBIO_WAITFORVSYNC ioctl to wait for the
pan to complete. This patch moves the write to LDSA1R mirror reg into the
pan ioctl.  Tested on MS7724 board against 2.6.33-rc7

e296264977 OMAP: DSS2: Check ctx loss count only when starting the first clock
When OMAP PM layer is no-op/debug, the PM layer will increment context
loss count with every call. This resulted DSS2 to restore context
whenever a clock was enabled.

This commit checks the context loss count only when the context actually
could have been lost, ie. when enabling a clock when no clocks had been
previously enabled.

dd8079d6a9 OMAP: DSS2: DSI: configure all DSI VCs
Instead of configuring only VC0 to be usable, configure all four VCs
similarly. This is needed to utilize the other VCs.

Setting the FIFO sizes evenly for all VCs, regardless of how many VCs are
actually used, is not optimal. However, this affects only cases when
larger amounts of data are written or read via L4, meaning that normal use
cases are not affected.

At some point this could be optimized better to suit different use cases.
