+Subject: [PATCH] pmap: empty output or crashes on ppc/s390 caused by wrong
+ pidlist type
+
+Previously the pidlist variable was defined as unsigned long *
+whilst the openproc function accepts pid_t *.
+Both target types differ in size (8 != 4) and therefore the issue
+mainly affects big endian architectures.
+
+This commit changes the pidlist type to pid_t * so that it's
+compatible with openproc.
