      [SPARC]: Mark SBUS framebuffer ioctls as IGNORE in compat_ioctl.c · 8163904e
      由 David S. Miller 提交于 
      They are handled in a ->compat_ioctl() handler, so it's just noise
when compat_ioctl.c warns which occurs when they are used on non-SBUS
framebuffer devices.

      [VIDEO]: Fix OOPS in all SBUS framebuffer drivers. · c7f439b9
      由 David S. Miller 提交于 
      All of these drivers use a silly:

struct all_info {
	struct fb_info info;
	struct foo_par par;
};

struct all_info *all = kzalloc(sizeof(*all), GFP_KERNEL);
all->info.par = &all->par;

etc. etc. code sequence, basically replicating the provided
framebuffer_alloc()/framebuffer_release(), and doing it badly.

Not only is this massive code duplication, it also caused a
bug in that we weren't setting the fb_info->device pointer
which results in an OOPS when fb_is_primary_device() runs.

Fix all of this by using framebuffer_{alloc,release}() and
passing in "&of_device->dev" as the device pointer.

      [SPARC]: Fix serial console device detection. · c73fcc84
      由 David S. Miller 提交于 
      The current scheme works on static interpretation of text names, which
is wrong.

The output-device setting, for example, must be resolved via an alias
or similar to a full path name to the console device.

Paths also contain an optional set of 'options', which starts with a
colon at the end of the path.  The option area is used to specify
which of two serial ports ('a' or 'b') the path refers to when a
device node drives multiple ports.  'a' is assumed if the option
specification is missing.

This was caught by the UltraSPARC-T1 simulator.  The 'output-device'
property was set to 'ttya' and we didn't pick upon the fact that this
is an OBP alias set to '/virtual-devices/console'.  Instead we saw it
as the first serial console device, instead of the hypervisor console.

The infrastructure is now there to take advantage of this to resolve
the console correctly even in multi-head situations in fbcon too.

Thanks to Greg Onufer for the bug report.
