| * | [PATCH] spin_unlock_bh() and preempt_check_resched()Samuel Thibault2005-05-211-4/+4
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In _spin_unlock_bh(lock): do { \ _raw_spin_unlock(lock); \ preempt_enable(); \ local_bh_enable(); \ __release(lock); \ } while (0) there is no reason for using preempt_enable() instead of a simple preempt_enable_no_resched() Since we know bottom halves are disabled, preempt_schedule() will always return at once (preempt_count!=0), and hence preempt_check_resched() is useless here... This fixes it by using "preempt_enable_no_resched()" instead of the "preempt_enable()", and thus avoids the useless preempt_check_resched() just before re-enabling bottom halves.

| | * [SCSI] implement parameter limits in the SPI transport classJames Bottomley2005-05-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a basic need not to have parameters go under or over certain values when doing domain validation. The basic ones are max_offset, max_width and min_period This patch makes the transport class take and enforce these three limits. Currently they can be set by the user, although they could obviously be read from the HBA's on-board NVRAM area during slave_configure (if it has one).

Since the DataFlash chip will automatically erase pages when writing, the cleanmarkers are not needed - so cleanmarker_oob = false and cleanmarker_size = 0 DataFlash page-sizes are not a power of two (they're multiples of 528 bytes). The SECTOR_ADDR macro (added in the previous core patch) is replaced with a (slower) div/mod version if CONFIG_JFFS2_FS_DATAFLASH is selected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver model has a "detach_state" mechanism that: - Has never been used by any in-kernel drive; - Is superfluous, since driver remove() methods can do the same thing; - Became buggy when the suspend() parameter changed semantics and type; - Could self-deadlock when called from certain suspend contexts; - Is effectively wasted documentation, object code, and headspace. This removes that "detach_state" mechanism; net code shrink, as well as a per-device saving in the driver model and sysfs.

It does not fix the race it was supposed to fix fully. - Remove unused P6 definitions - Add support for performance counter based watchdog on P4 systems. This allows to run it only once per second, which saves some CPU time. Previously it would run at 1000Hz, which was too much. Code ported from i386 Make this the default on Intel systems. - Use check_nmi_watchdog with local APIC based nmi - Fix race in touch_nmi_watchdog - Fix bug that caused incorrect performance counters to be programmed in a few cases on K8. - Remove useless check for local APIC - Use local_t and per_cpu variables for per CPU data. - Keep other CPUs busy during check_nmi_watchdog to make sure they really tick when in lapic mode. - Only check CPUs that are actually online. - Various other fixes. - Fix fallback path when MSRs are unimplemented Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | [PATCH] x86_64: Add pmtimer supportAndi Kleen2005-05-172-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are unfortunately more and more multi processor Opteron systems which don't have HPET timer support in the southbridge. This covers in particular Nvidia and VIA chipsets. They also don't guarantee that the TSCs are synchronized between CPUs; and especially with MP powernow the systems are nearly unusable because the time gets very inconsistent between CPUs. The timer code for x86-64 was originally written under the assumption that we could fall back to the HPET timer on such systems. But this doesn't work there. Another alternative is to use the ACPI PM timer as primary time source. This patch does that. The kernel only uses PM timer when there is no other choice because it has some disadvantages. Ported over from i386. It should be faster than the i386 version because I dropped the "read three times" workaround, but is still considerable slower than HPET and also does not work together with vsyscalls which have to be disabled.
