[PATCH] s390: fadvise hint values.
Add special case for the POSIX_FADV_DONTNEED and POSIX_FADV_NOREUSE hint
values for s390-64. The user space values in the s390-64 glibc headers for
these two defines have always been 6 and 7 instead of 4 and 5. All 64 bit
applications therefore use the "wrong" values. To get these applications
working without recompiling the kernel needs to accept the "wrong" values.
Since the values for s390-31 are 4 and 5 the compat wrapper for fadvise64
and fadvise64_64 need to rewrite the values for 31 bit system calls.
