2006-11-30Fix jiffies.h commentChase Venters
jiffies.h includes a comment informing that jiffies_64 must be read with the assistance of the xtime_lock seqlock. The comment text, however, calls jiffies_64 "not volatile", which should probably read "not atomic".

2006-09-26[PATCH] Add 64bit jiffies compares (for use with get_jiffies_64)Dmitriy Zavin
The current time_before/time_after macros will fail typechecks when passed u64 values (as returned by get_jiffies_64()). On 64bit systems, this will just result in a warning about mismatching types without explicit casts, but since unsigned long and u64 (unsigned long long) are of same size, it will still work. On 32bit systems, a long is 32bits, so the value from get_jiffies_64() will be truncated by the cast and thus lose all the precision gained by 64bit jiffies.

There is currently no affected user in the tree, but usage is less surprising that way. Signed-off-by: Uwe Zeisberger <Uwe_Zeisberger@digi.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-04-09[PATCH] x86_64: Fix drift with HPET timer enabledJordan Hargrave
If the HPET timer is enabled, the clock can drift by ~3 seconds a day. This is due to the HPET timer not being initialized with the correct setting (still using PIT count). If HZ changes, this drift can become even more pronounced. HPET patch initializes tick_nsec with correct tick_nsec settings for HPET timer. Vojtech comments: "It's not entirely correct (it assumes the HPET ticks totally exactly), but it's significantly better than assuming the PIT error there."

2006-01-10[PATCH] hrtimer: move div_long_long_rem out of jiffies.hThomas Gleixner
move div_long_long_rem() from jiffies.h into a new calc64.h include file, as it is a general math function useful for other things than the jiffy code.

2005-09-10[PATCH] include: update jiffies/{m,u}secs conversion functionsNishanth Aravamudan
Clarify the human-time units to jiffies conversion functions by using the constants in time.h. This makes many of the subsequent patches direct copies of the current code.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
