By the way. If anyone can point out an existing EXPORTed
"count number of one bits" in a word function, then I'll very happily
submit a followup patch to remove this (below) and use that instead.
..
+static int mv_count_pmp_links(unsigned int pmp_map)
+{
+ unsigned int link_count = 0;
+
+ while (pmp_map) {
+ link_count += (pmp_map & 1);
+ pmp_map >>= 1;
+ }
+ return link_count;
+}
..
I grepped for one, but didn't find one.
But there must be several of them already out there (?)
Speed is unimportant here, so this version above
has been left simple -- no table lookups.
