Ingo Molnar fbe1bf1406 One vdso fix for a longstanding ASLR bug that's been in the news lately. 
The vdso base address has always been randomized, and I don't think there's
 anything particularly wrong with the range over which it's randomized,
 but the implementation seems to have been buggy since the very beginning.
 
 This fixes the implementation to remove a large bias that caused a small
 fraction of possible vdso load addresess to be vastly more likely than
 the rest of the possible addresses.
