2.6.1 fb.h patch for userland application

2.6.1 fb.h patch for userland application

[Dirk Behme]

Hello,

I had problems to use linux/fb.h from 2.6.1 to compile userland 
application microwindows. I made some changes to get microwindows 0.90 
to compile, please see patch below.

The include files atomic.h and spinlock.h are necessary for spinlock_t 
and atomic_t. workqueue.h doesn't compile for userspace application and 
doesn't seem to be necessary at all (?). u8 is undefined while compiling 
for userspace, use __u8 instead.

Is this patch OK?

Dirk

Its already included in 2.6.3-rc1. Grab this kernel and give it a try.
