* readahead: make mmap_miss an unsigned intWu Fengguang2009-06-161-1/+1
| | | | | | | | | | | | | | | This makes the performance impact of possible mmap_miss wrap around to be temporary and tolerable: i.e. MMAP_LOTSAMISS=100 extra readarounds. Otherwise if ever mmap_miss wraps around to negative, it takes INT_MAX cache misses to bring it back to normal state. During the time mmap readaround will be _enabled_ for whatever wild random workload. That's almost permanent performance impact.

* time: move PIT_TICK_RATE to linux/timex.hArnd Bergmann2009-06-1613-21/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | PIT_TICK_RATE is currently defined in four architectures, but in three different places. While linux/timex.h is not the perfect place for it, it is still a reasonable replacement for those drivers that traditionally use asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency. Note that for Alpha, the actual value changed from 1193182UL to 1193180UL. This is unlikely to make a difference, and probably can only improve accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE a few years ago, after which every existing instance was getting changed to 1193182. According to the specification, it should be 1193181.818181...

Timers firing on busy CPUs are not migrated. While migrating hrtimers, care should be taken to check if migrating a hrtimer would result in a latency or not. So we compare the expiry of the hrtimer with the next timer interrupt on the target cpu and migrate the hrtimer only if it expires *after* the next interrupt on the target cpu. So, added a clockevents_get_next_event() helper function to return the next_event on the target cpu's clock_event_device.

This framework is needed because pinned timers are expected to fire on the same CPU on which they are queued. So it is essential to identify these and not migrate them, in case there are any. For regular timers, the currently existing add_timer_on() can be used queue pinned timers and subsequently mod_timer_pinned() can be used to modify the 'expires' field. For hrtimers, new modes HRTIMER_ABS_PINNED and HRTIMER_REL_PINNED are added to queue cpu-pinned hrtimer.

SHIFT_PLL, which reduces the stiffness of the freq adjustments, was designed to be inversely linked to HZ, and the reference value of 4 was designed for Unix systems using HZ=100. However Linux's clock steering code mostly independent of HZ. So this patch reduces the SHIFT_PLL value from 4 to 2, which causes NTPd behavior to match kernels prior to 2.6.19, greatly reducing convergence times, and improving close synchronization through environmental thermal changes. The patch also changes some l's to L's in nearby code to avoid misreading 50l as 501.

The cache size is controlled by neigh_table gc thresholds. Remove also expiremental and obsolete markings as the API originally intended for arp caching is useful for implementing ARP-like protocols (e.g. NHRP) in user space and has been there for a long enough time.

If the IEEE802154 symbol is 'm', the bool becomes 'y'. This allows tristate symbols under IEEE802154_DRIVERS to be configured as 'y' and cause build problems. Changing the menuconfig bool to a tristate fixes this. drivers/built-in.o: In function `fake_scan_req': fakehard.c:(.text+0x46d625): undefined reference to `ieee802154_nl_scan_confirm' drivers/built-in.o: In function `fake_disassoc_req': fakehard.c:(.text+0x46d66f): undefined reference to `ieee802154_nl_disassoc_confirm' drivers/built-in.o: In function `fake_assoc_req': fakehard.c:(.text+0x46d6be): undefined reference to `ieee802154_nl_assoc_confirm' Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Acked-by: Sergey Lapin <slapin@ossfans.org> Signed-off-by: David S.
