Previous approach with passing the section contents as a command line
option proven to be error-prone, as it hits the command line option size
limit on some kmods. Move the reading and processing of the section
contents inside the awk script itself; it also saves a bit (around 3—4%)
of time on the kernels with indirect __crc_* symbols:
$ for i in ./lib/modules/*; do \
echo "====== $i ====="; \
diff -u <(find $i | ./find-provides.ksyms.old) <(find $i | ./find-provides.ksyms.new); \
echo -n "old: "; find $i | time ./find-provides.ksyms.old > /dev/null; \
echo -n "new: "; find $i | time ./find-provides.ksyms.new > /dev/null; \
done

* find-provides.ksyms: Add assign to revbytes the result of endianness
chack test instead of the code snippet; do not generate SECTDATA
variable; do not pass SECTDATA to the awk script; pass module
and revbytes to the awk script; retrieve the section data
into the sectdata variable and perform the byte re-shuffling
in accordance to the revbytes value in the BEGIN section of the awk
script.
* find-requires.ksyms (all_provides): Likewise.
