From 9e74047542cbe90bd63660638ceb30313327027f Mon Sep 17 00:00:00 2001 From: "Peter S. Mazinger" Date: Wed, 6 Apr 2011 15:36:54 +0200 Subject: posix_fadvise: make posix_fadvise[64] similar on all archs Remove all versions, that can be covered by the common one. Drop incorrectly implemented fallback support, if __NR_fadvise64_64 is not available. To support 64 bit ppc, move ppc support into common. Cleanup including headers. Signed-off-by: Peter S.
