34308fd4a2 acornfb: remove fb_mmap function
The driver's fb_mmap function is essentially the same as a generic fb_mmap
function.  Delete driver's function and use the generic one.

A difference is that generic function marks frame buffer memory as VM_IO |
VM_RESERVED.  The driver's function marks it as VM_IO only.

24f01dcb53 mb862xxfb: use CONFIG_OF instead of CONFIG_PPC_OF
With this change, the driver builds fine on Microblaze, which helps
allyesconfig compile tests.

I did not test sparc, but the change should have the same effect there.

336e747eeb mb862xxfb: restrict compliation of platform driver to PPC
The OpenFirmware part of this driver is uncompilable on SPARC due to it's
dependance on several PPC specific functions.

Restricting this to PPC to prevent these build errors:

drivers/video/mb862xx/mb862xxfb.c: In function 'of_platform_mb862xx_probe':

This was found using randconfig builds.

39000d654c Samsung SoC Framebuffer driver: add Alpha Channel support
Add support for the ARGB1888 and ARGB4888 hardware to the Samsung SoC
Framebuffer driver (s3c-fb.c).

ARGB1888 and ARGB4888 is decided by var->transp.length and this variable
is set by s3c_fb_check_var().

In s3c_fb_check_var(), if var->vits_per_pixel is 25 or 28, then
var->transp.length would be 1 or 3.

Therefore alpha mode(ARGB1888 or ARGB4888) could be decided through that
variable.

For using alpha mode, you need to set the following: This code should be
added to your machine code as platform data.

static struct s3c_fb_pd_win xxx_fb_win0 = {
	/* this is to ensure we use win0 */
	.win_mode = {
		.pixclock		= (8+8+8+240)*(38+4+38+400),
		.left_margin	= 8,
		.right_margin	= 8,
		.upper_margin	= 38,
		.lower_margin	= 38,
		.hsync_len		= 8,
		.vsync_len		= 4,
		.xres			= 240,
		.yres			= 400,
	},
	.max_bpp		= 32,
	.default_bpp	= 24,
};

static struct s3c_fb_pd_win xxx_fb_win1 = {
	.win_mode = {
		.pixclock		= (8+8+8+240)*(38+4+38+400),
		.left_margin	= 8,
		.right_margin	= 8,
		.upper_margin	= 38,
		.lower_margin	= 38,
		.hsync_len		= 8,
		.vsync_len		= 4,
		.xres			= 240,
		.yres			= 400,
	},
	.max_bpp		= 32,
	.default_bpp	= 28,
};

static struct s3c_fb_platdata xxx_lcd_pdata __initdata = {
	.win[0]		= &ncp_fb_win0,
	.win[1]		= &ncp_fb_win1,
	.vidcon0	= VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB,
	.vidcon1	= VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC,
	.setup_gpio	= xxx_fb_gpio_setup,
};

s3c_fb_set_platdata(&xxx_lcd_pdata);

The above code sets pixelformat for window0 layer to RGB888 and window1
layer to ARGB4888.

97b9a5a28b atmel-lcdc: fix pixclock upper bound detection
AFAICT the code which checks that the requested pixclock value is within
bounds is incorrect.  It ensures that the lcdc core clock is at least
(bytes per pixel) times higher than the pixel clock rather than just
greater than or equal to.

There are tighter restrictions on the pixclock value as a function of bus
width for STN panels but even then it isn't a simple relationship as
currently checked for.  IMO either something like the below patch should
be applied or else more detailed checking logic should be implemented
which takes in to account the panel type as well.

ae52bb2384 fbdev: move logo externs to header file
Now we have __initconst, we can finally move the external declarations for

James' ack dates back to the previous submission (way to long ago), when the
logos were still __initdata, which caused failures on some platforms with some
toolchain versions.

8f3128e714 lis3: add click function
The LIS302DL accelerometer chip has a 'click' feature which can be used to
detect sudden motion on any of the three axis.  Configuration data is
passed via spi platform_data and no action is taken if that's not
specified, so it won't harm any existing platform.

To make the configuration effective, the IRQ lines need to be set up
appropriately.  This patch also adds a way to do that from board support
code.

The DD_* definitions were factored out to an own enum because they are
specific to LIS3LV02D devices.

a002ee896d lis3: remove automatic shutdown of the device
After measurement on my laptop, it seems that turning off the device does
not bring any energy saving (within 0.1W precision).  So let's keep the
device always on.  It simplifies the code, and it avoids the problem of
reading a wrong value sometimes just after turning the device on.

Moreover, since commit ef2cfc790b had been
too zealous, the device was actually never turned off anyway.  This patch
also restores the damages done by this commit concerning the
initialisation/poweroff.

Also do more clean up with the usage of the lis3_dev global variable.

	else if (!node->rb_right)

guarantee that old->rb_right is set in the final else branch, therefore
we can omit checking that again.

4c60117811 rb_tree: make clear distinction between two different cases in rb_erase()
There are two cases when a node, having 2 childs, is erased:
'normal case': the successor is not the right-hand-child of the node to be erased
'special case': the successor is the right-hand child of the node to be erased

Here some ascii-art, with following symbols (referring to the code):
O: node to be deleted
N: the successor of O
P: parent of N
C: child of N
L: some other node

8e8a2dea0c lib/genalloc.c: remove unmatched write_lock() in gen_pool_destroy
There is a call to write_lock() in gen_pool_destroy which is not balanced
by any corresponding write_unlock().  This causes problems with preemption
because the preemption-disable counter is incremented in the write_lock()
call, but never decremented by any call to write_unlock().  This bug is
gen_pool_destroy, and one of them is non-x86 arch-specific code.

55e331cf7e drivers: add support for the TI VLYNQ bus
Add support for the TI VLYNQ high-speed, serial and packetized bus.

This bus allows external devices to be connected to the System-on-Chip and
appear in the main system memory just like any memory mapped peripheral.
It is widely used in TI's networking and multimedia SoC, including the AR7
SoC.

f324edc85e console: make blank timeout value a boot option
The console blank timer is currently hardcoded to 10*60 seconds which
might be annoying on systems with no input devices attached to wake up the
console again.  Especially during development, disabling the screen saver
can be handy - for example when debugging the root fs mount mechanism or
other scenarios where no userspace program could be started to do that at
runtime from userspace.

This patch defines a core_param for the variable in charge which allows
users to entirely disable the blank feature at boot time by setting it 0.
The value can still be overwritten at runtime using the standard ioctl
call - this just allows to conditionally change the default.

73d05163d1 eisa.ids: add Network Peripherals FDDI boards
Add EISA IDs for Network Peripherals FDDI boards.  Descriptions taken from
the respective EISA configuration files.

It's unlikely we'll ever support these cards, the problem being the lack
of documentation.  Assuming the policy for the EISA ID database is the
same as for PCI I'm sending these entries for the sake of completeness.

e4c9dd0fba kmap_types: make most arches use generic header file
Convert most arches to use asm-generic/kmap_types.h.

Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h,
controlled by __WITH_KM_FENCE from each arch's kmap_types.h file.

Would be nice to be able to add custom KM_types per arch, but I don't yet
see a nice, clean way to do that.

Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and
68k(tonyb).

Note: avr32 should be able to remove KM_PTE2 (since it's not used) and
then just use the generic kmap_types.h file.  Get avr32 maintainer
approval.

c67ae69b66 hexdump: remove the trailing space
For example:
        hex_dump_to_buffer("AB", 2, 16, 1, buf, 100, 0);
        pr_info("[%s]\n", buf);

I'd expect the output to be "[41 42]", but actually it's "[41 42 ]"

This patch also makes the required buf to be minimum.  To print the hex
format of "AB", a buf with size 6 should be sufficient, but
hex_dump_to_buffer() required at least 8.
