Hi, This series is made of patches from [1]. I've added a test and noticed that madvise(MADV_DONTNEED) was broken on alpha, fixing which required adding per-arch MADV_* definitions. This in turn affected the strace patch, so it made sense to make a series out of the results.
Patch 1 adds MADV_* constants for all architectures. Patch 2 fixes the alpha bug. Patch 3 adds madvise() support to strace. Patch 4 adds MADV_DONTNEED support for file mappings. Patch 5 adds a test.
