This entry in the DMI blacklist table is missing it's NO_MATCH tags, which means the struct gets padded instead of filled with the desired NO_MATCH data which is {255, NULL} Usually not fatal it seems, but there have been numerous cases in Red Hat bugzilla where this did get tripped up, and caused an immediate reset on these boards. Not fun to track down. Signed-off-by:Dave Jones <davej@redhat.com> Signed-off-by:

Adds a dummy flush_tlb_page_nohash() called by ptep_set_access_bits(), to be used if we ever have a ppc64 CPU with software loaded TLB. Signed-off-by:

ARGH. Missed one file. Here is an additional patch (missed tlbflush.h patch) Sorry. This adds the definiction of flush_tlb_page_nohash() that was missing from the previous patch fixing SW-TLB loaded PPCs Signed-off-by:

The recent introduction of ptep_set_access_flags() with the optimisation of not flushing the TLB unfortunately broke ppc32 CPUs with no hash table. The data access exception code path in assembly for these doesn't properly deal with the case where the TLB entry is present with the wrong PAGE_RW and will just call do_page_fault again instead of just replacing the TLB entry. Fixing the asm code for all the different CPU types affected (yah, embedded PPCs all have different MMUs =P) is painful and need testing I can't do at the moment, so here's a fix that will just flush the TLB page when changing the access flags on non-hash based machines. Please apply. Signed-off-by: -

The scheduler changes had another thing missing: the appreciation of sync wakeups. (I had this in one of the earlier sched-domains cleanup patches before but it got lost in the shuffle.) When a sync waker is waking, we should subtract its load from the current load - it will schedule away for sure in the near future. That's what the "sync" bit means. This change is necessary because with the sched-domains balancer we have a much more sensitive cpu-load estimator, and in this particular context of try_to_wake_up() the sync waker's effect will always be part of the load. Patch against your patch attached. In my testing there's an additional increase in bw_pipe numbers on a dual P2 box, it went from 110-120 MB/sec to 120-130 MB/sec. Signed-off-by:

watchdog.h is using __u8 and __u32 from linux/types.h, so it needs to include it.

Lets just remove it. It's been disabled some time ago, and there's no chance of it ever getting resurrected. PATA TCQ has so many technical short comings, that it was never really interesting I'm afraid. Signed-off-by:

From: Colin Leroy <colin@colino.net> Paulus brought this up on IRC, it seems to be a bad DRM merge: The code #ifndef VMAP_4_ARGS if ( dev->agp->cant_use_aperture ) return -EINVAL; #endif in DRM(agp_acquire) should be removed altogether in a 2.6 kernel because its vmap() takes 4 arguments; however, only the guards seem to have been removed, which causes this function to erroneously fail if the AGP aperture can't be directly accessed by the CPU.

The attached patch fixes the EDID parsing for PPC on rivafb. It actually finds the EDID info in the OF Tree now. I grabbed this from BenHs Tree as of 2.6.5-rc3. The current code has no chance to work since it doesn't walk the device tree. This helps rivafb on PPC at least a bit further... Signed-off-by:

David Mosberger noticed bw_pipe was way down on sched-domains kernels on SMP systems. That is due to two things: first, the previous wake-affine logic would *always* move a pipe wakee onto the waker's CPU. With the scheduler rework, this was toned down a lot (but extended to all types of wakeups). One of the ways this was damped was with the logic: don't move the wakee if its CPU is relatively idle compared to the waker's CPU. Without this, some workloads would pile everything up onto a few CPUs and get lots of idle time. However, the fix was a bit of a blunt hack: if the wakee runqueue was below 50% busy, and the waker's was above 50% busy, we wouldn't do the move. I think a better way to capture it is what this patch does: if the wakee runqueue is below 100% busy, and the sum of the two runqueue's loads is above 100% busy, and the wakee runqueue is less busy than the waker runqueue (ie. CPU utilisation would drop if we do the move), then we don't do the move. After I fixed this, I found things were still getting bounced around quite a bit. The reason is that we were attempting very aggressive idle balancing in order to cut down idle time in a dbt2-pgsql workload, which is particularly sensitive to idle. After having Mark Wong (markw@osdl.org) retest this load with this patch, it looks like we don't need to be so aggressive. I'm glad to be rid of this because it never sat too well with me. We should see slightly lower cost of schedule and slightly improved cache impact with this change too. Mark said: --- This looks pretty good: metric kernel 2334 2.6.7-rc2 2298 2.6.7-rc2-mm2 2329 2.6.7-rc2-mm2-sched-more-wakeaffine --- ie. within the noise. David said: --- Oooh, me likeee! Host OS Pipe AF UNIX --------- ------------- ---- ---- caldera.h Linux 2.6.6 3424 2057 (plain 2.6.6) caldera.h Linux 2.6.7-r 333. 1402 (original 2.6.7-rc1) caldera.h Linux 2.6.7-r 3086 4301 (2.6.7-rc1 with your patch) Pipe-bandwidth is still down about 10% but that may be due to unrelated changes (or perhaps warmup effects?). The AF UNIX bandwidth is just mindboggling. Moreover, with your patch 2.6.7-rc1 shows better context-switch times and lower communication latencies (more like the numbers you're getting on UP). So it seems like the overall balance of keeping things on the same CPU vs. distributing them across CPUs is improved. --- I also ran some tests on the NUMAQ. kernbench, dbench, hackbench, reaim were much the same. tbench was improved, very much so when clients < NR_CPU.

This condtion on this loop is primarily to avoid the loop if it doesn't appear to be needed. However it optimises a little too much and there is a case where it skips the loop when it is really needed. This patch fixes it. Signed-off-by:
