From 0c37ec2aa88bd8a6aaeb284ff5c86f4c6d8e8469 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 14 Nov 2005 14:55:58 +1100 Subject: [PATCH] powerpc: vdso fixes (take #2) This fixes various errors in the new functions added in the vDSO's, I've now verified all functions on both 32 and 64 bits vDSOs. It also fix a sign extension bug getting the initial time of day at boot that could cause the monotonic clock value to be completely on bogus for 64 bits applications (with either the vDSO or the syscall) on powermacs.
