[<ro...@us...>]

Update of /cvsroot/ltp/ltp/testcases/kernel/syscalls/delete_module
In directory sc8-pr-cvs1:/tmp/cvs-serv6992/delete_module

Modified Files:
	delete_module02.c 
Log Message:
Applied 31bit emulation s390x patch from Susanne Wintenberger:

The testcases fail on the emulation layer, since -1 casted to an address is valid in this environment. In order to generate invalid addresses portable, I used the mmap call with protection PROT_NONE.
Can you please apply the fixes. Thanks
