This patch should fix the crashes we have been seeing on 64-bit powerpc systems with a memory hole when sparsemem is enabled. I'd appreciate it if people who know more about NUMA and sparsemem than me could look over it. There were two bugs. The first was that if NUMA was enabled but there was no NUMA information for the machine, the setup_nonnuma() function was adding a single region, assuming memory was contiguous. The second was that the loops in mem_init() and show_mem() assumed that all pages within the span of a pgdat were valid (had a valid struct page). I also fixed the incorrect setting of num_physpages that Mike Kravetz pointed out. Signed-off-by:

Although the comment around the allocation code tells us that the layer-3 specific protocol tables will be freed when cleaning up, they aren't. And this makes nfsim complain loudly... Signed-off-by:

Our performance validation on 2.6.15-rc1 caught a disastrous performance regression on ia64 with netperf (-98%) and volanomark (-58%) compares to previous kernel version 2.6.14-git7. See the following chart (result group 1 & 2). http://kernel-perf.sourceforge.net/results.machine_id=26.html We have root caused it to commit 64c7c8f8 This changeset broke the ia64 task resched notification. In sched.c:resched_task(), a reschedule IPI is conditioned upon TIF_POLLING_NRFLAG. However, the above changeset unconditionally set the polling thread flag for idle tasks regardless whether pal_halt_light is in use or not. As a result, resched IPI is not sent from resched_task(). And since the default behavior on ia64 is to use pal_halt_light, we end up delaying the rescheduling task until next timer tick, and thus cause the performance regression. This fixes the performance bug. I'm glad our performance suite is turning up bad performance bug like this in time. Signed-off-by:

Despite the fact that md threads don't need to be signalled, and won't respond to signals anyway, we need to have an 'interruptible' wait, else they stay in 'D' state and add to the load average. (akpm: the signal_pending() test is unneeded - we'll fix that up in the next round. For now, leave it there because that's how the code used to be). Signed-off-by:

Being kernel-threads, nfsd servers don't get pre-empted (depending on CONFIG). If there is a steady stream of NFS requests that can be served from cache, an nfsd thread may hold on to a cpu indefinitely, which isn't very friendly. So it is good to have a cond_resched in there (just before looking for a new request to serve), to make sure we play nice. Signed-off-by:

Lots of good changes to the driver lately that userspace will care about the version of the driver. Bump the version from 36.0 to 38.0 to be higher than 37 that the 2.4 driver came out with a few weeks ago which doesn't have all the same changes. Signed-off-by:

This is needed for large multinode IBM systems which have a sparse APIC space in clustered mode, fully covering the available 8 bits. The previous kernels would limit the local APIC number to 127, which caused it to reject some of the CPUs at boot. I increased the maximum and shrunk the apic_version array a bit to make up for that (the version is only 8 bit, so don't need an full int to store) Cc: Chris McDermott <lcm@us.ibm.com> Signed-off-by:

CONFIG_CHECKING covered some debugging code used in the early times of the port. But it wasn't even SMP safe for quite some time and the bugs it checked for seem to be gone. This patch removes all the code to verify GS at kernel entry. There haven't been any new bugs in this area for a long time. Previously it also covered the sysctl for the page fault tracing. That didn't make much sense because that code was unconditionally compiled in. I made that a boot option now because it is typically only useful at boot. Signed-off-by:

The current x86_64 NUMA memory code is inconsequent when it comes to node memory ranges. The exact behaviour varies depending on which config option that is used. setup_node_bootmem() has start and end as arguments and these are used to calculate the size of the node like this: (end - start). This is all fine if end is pointing to the first non-available byte. The problem is that the current x86_64 code sometimes treats it as the last present byte and sometimes as the first non-available byte. The result is that some configurations might lose a page at the end of the range. This patch tries to fix CONFIG_ACPI_NUMA, CONFIG_K8_NUMA and CONFIG_NUMA_EMU so they all treat the end variable as the first non-available byte. This is the same way as the single node code. The patch is boot tested on dual x86_64 hardware with the above configurations, but maybe the removed code is needed as some workaround? Signed-off-by:

The logging for boot errors was turned off because it was broken on some AMD systems. But give Intel EM64T systems a chance because they are supposed to be correct there. The advantage is that there is a chance to actually log uncorrected machine checks after the reset. Signed-off-by:
