From 36dfbbf136db0d645bacfd42ce7d9d6928ea532d Mon Sep 17 00:00:00 2001 From: Satoru Takeuchi Date: Fri, 15 Feb 2013 16:58:14 +0900 Subject: timers/x86/hpet: Use HPET_COUNTER to specify the hpet counter in vread_hpet() vread_hpet() uses "0xf0" as the offset of the hpet counter. To clarify the meaning of this code, it should use symbolic name, HPET_COUNTER, instead. Signed-off-by: Satoru Takeuchi Cc: H. Peter Anvin Cc: "H.
