# XXX Fix this properly:

# The grep 6/7 DONTNEED/NOREUSE are a hack to filter out the s/390 oddity See
# tools/include/uapi/linux/fadvise.h for details.

# Probably fix this when generating the string tables per arch so that We can
# reliably process on arch FOO a perf.data file collected by 'perf trace
# record' on arch BAR, e.g. collect on s/390 and process on x86.
