+    Fix tst-pkey.c pkey_alloc return checks and manual
+    
+    This test was failing in some powerpc systems as it was not checking
+    for ENOSPC return.
+    
+    As said on the Linux man-pages and can be observed by the implementation
+    at mm/mprotect.c in the Linux Kernel source.  The syscall pkey_alloc can
+    return EINVAL or ENOSPC.  ENOSPC will indicate either that all keys are
+    in use or that the kernel does not support pkeys.
