They say now that asm/semaphore.h is a deprecated location as of 2.6.26: 

https://kerneltrap.org/mailarchive/linux-kernel/2008/2/28/1010394

The file is in the linux-headers-2.6.29.1 extension, it is linux/semaphore.h.  Some apps have been made to check for kernel version to determine whether to go with asm/semaphore.h or linux/semaphore.h.  Reference:

https://issues.asterisk.org/view.php?id=14016

So if you find the references to asm/semaphore.h in the source you are trying to build, it seems they can be changed to linux/semaphore.h to allow compile.  It couldn't hurt to try anyway.

thanks a lot, this information put me on the right track. I was having problem compiling modules from the sources supplyied by the advantech compagny. There sources wasn't up to date for more recent linux version like tinycore, they were also another bug that I fixed too, finnally by changing the include file from asm/semaphore.h  by /linux/semaphore.h, the modules compiled succesfully.
thanks a lot
