   fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that
   switched over to using 'tun->socket.sk' instead of the redundantly

0035fe00f7 fbcon: don't use vc_resize() on initialization
Catalin and kmemleak spotted a leak of a VC screen buffer in
vc_allocate() due to the following chain of events:

	vc_allocate()
	  visual_init(init=1)
	    vc->vc_sw->con_init(init=1)
              fbcon_init()
	        vc_resize()
	          vc->screen_buf = kmalloc()
	  vc->screen_buf = kmalloc()

The common way for the VC drivers is to set the screen dimension
parameters manually in the init case and only call vc_resize() for
!init - which allocates a screen buffer according to the new
dimensions.

fbcon instead would do vc_resize() unconditionally and afterwards set
the dimensions manually (again) for !init - i.e. completely upside
down.  The vc_resize() allocated buffer would then get lost by
vc_allocate() allocating a fresh one.

Use vc_resize() only for actual resizing to close the leak.

Set the dimensions manually only in initialization mode to remove the
redundant setting in resize mode.

521594442c viafb: fix rmmod bug
This fixes a bug caused by changing pointers (viafb_mode, viafb_mode1)
assigned by module_param.  It reduces driver complexity by not needlessly
changing these vars as they are only read once and removing now
superfluous code.

On unpatched kernels loading viafb with viafb_mode or viafb_mode1 option
used and afterwards unloading it results in:

This is caused by the current code changing the pointers assigned by
module_param.  During unload it tries to free the memory the pointers
point at which is now part of an internal structure.

The patch simply avoids changing the pointers.  This is okay as they are
read only once during the initialization process.

3730793d45 fbmon: work around compiler bug in gcc-2.4.2
There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent
he loop counter is of type 'unsigned char' and it should count to 128.

The compiler will incorrectly decide that a trivial loop like this:

	unsigned char i, ...

	for (i = 0; i < 128; i++) {
		..

is endless, and will compile it to a single instruction that just
branches to itself.

This was triggered by the addition of '-fno-strict-overflow', and we
could play games with compiler versions and go back to '-fwrapv'
instead, but the trivial way to avoid it is to just make the loop
induction variable be an 'int' instead.

Thanks to Krzysztof Oledzki for reporting and testing and to Troy Moure
for digging through assembler differences and finding it.

0741241c6b connector: make callback argument type explicit
The connector documentation states that the argument to the callback
function is always a pointer to a struct cn_msg, but rather than encode it
in the API itself, it uses a void pointer everywhere.  This doesn't make
much sense to encode the pointer in documentation as it prevents proper C
type checking from occurring and can easily allow people to use the wrong
pointer type.  So convert the argument type to an explicit struct cn_msg
pointer.

405f55712d headers: smp_lock.h redux
* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

This way they'll be properly initialized early enough for users that may
touch them before the framebuffer has been registered.

Drivers that allocate their fb_info structure some other way (like
matrocfb's broken static allocation) need to be fixed up appropriately.

600ce1a0fa drivers/video/s3c-fb.c: fix clock setting for Samsung SoC Framebuffer
Correct the CLKVAL_F field value of VIDEO MAIN CONTROLLER 0 REGITSTER.

Frame Rate is 1 / [ { (VSPW+1) + (VBPD+1) + (LIINEVAL + 1) + (VFPD+1)
} x {(HSPW+1) + (HBPD +1)
+ (HFPD+1) + (HOZVAL + 1) } x { ( CLKVAL+1 ) / ( Frequency of Clock
source ) } ] and VCLK = Video Clock Source / (CLKVAL +1).

therefore CLKVAL_F should be "CLKVAL_F = Frequency of Clock source / pixel
clock * refresh".

for this, I added refresh value in platform data like below.

static struct s3c_fb_pd_win xxx_fb_win0 = {
	/* this is to ensure we use win0 */
	.win_mode = {
		.refresh	= 60,
		.pixclock	= (66+4+2+480)*(15+5+3+800),
		.left_margin	= 66,
		.right_margin	= 2,
		.upper_margin	= 15,
		.lower_margin	= 3,
		.hsync_len	= 4,
		.vsync_len	= 5,
		.xres		= 480,
		.yres		= 800,
	},
	.max_bpp	= 32,
	.default_bpp	= 24,
};

static struct s3c_fb_platdata xxx_lcd_pdata __initdata = {
	.win[0]		= &xxx_fb_win0,
	.vidcon0	= VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB,
	.vidcon1	= VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC
			| VIDCON1_INV_VCLK | VIDCON1_INV_VDEN,
	.setup_gpio	= s5pc1xx_fb_gpio_setup_24bpp,
};

xxx_machine_init()
{
                   .
                   .
                   .
               s3c_fb_set_platdata(&xxx_lcd_pdata);
}

platform data defined in machine code should be setting using
s3c_fb_set_platdata().
