From e0d872d536bb93335d5905b09fe374a163486d43 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Wed, 30 Aug 2006 15:55:32 +1000 Subject: [POWERPC] Fix problem with time not advancing on 32-bit platforms This fixes a problem introduced in 5db9fa9593e2ff69f2b95f9d59229dc4faaa564d. The last_jiffy per-cpu variable is only 32 bits on 32-bit machines, but it was being compared with a 64-bit quantity (tb_next_jiffy), which resulted in time not advancing. This fixes it by changing last_jiffy to be 64 bits on all platforms. With this, we no longer need tb_last_stamp as a 32-bit version of tb_last_jiffy, so this gets rid of tb_last_stamp and we just use tb_last_jiffy instead. This also fixes a bug when the boot cpu is not online, because using tb_last_stamp could have caused the wrong timebase origin value to be used when calculating the time of day.
