#49 Cross-compiling linux-gpib for ARM target

[Lampus]

Hello.
I have successfully cross-compiled linux-gpib for ARM target, but with some ugly hacks. Keithley KUSB-488A with ni_usb_b driver were tested on AT91SAM9260 processor using ibtest program and DC power supply with GPIB interface.
linux-gpib version: SVN Revision 1584

Next problems have occurred during compilation:
1. implicit declaration of functions 'kmalloc' and 'kfree' in files drivers/gpib/cec/init.c and drivers/gpib/ines/ines_init.h
Solution: add #include <linux/slab.h>
2. implicit declaration of functions 'get_fs' and 'set_fs' in file drivers/gpib/lpvo_usb_gpib/lpvo_usb_gpib.c
Solution: add #include <asm/uaccess.h>
3. For some reasons gcc parameters don't contain include path ${LINUX_SRCDIR}/include

I added the missing header includes to svn, but I've never done any cross-compiling so I can't be much help there.
