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:

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:

On x86_64 arches, there is no way to choose ACPI_NUMA without having to choose K8_NUMA. CONFIG_K8_NUMA is not needed for Intel EM64T NUMA boxes. It also looks odd if you have to select ACPI_NUMA from the power management menu. This patch fixes those oddities. Patch does the following: 1. Makes NUMA a config option like other arches 2. Makes topology detection options like K8_NUMA dependent on NUMA 3. Choosing ACPI NUMA detection can be done from the standard "Processor type and features" menu AK: I fixed up the dependencies and changed the help texts a bit on top of Kiran's patch. Signed-off-by:

Keeping this function does not makes sense because it's a copied (and buggy) copy of sys_time. The only difference is that now.tv_sec (which is a time_t, i.e. a 64-bit long) is copied (and truncated) into a int (32-bit). The prototype is the same (they both take a long __user *), so let's drop this and redirect it to sys_time (and make sure it exists by defining __ARCH_WANT_SYS_TIME). Only disadvantage is that the sys_stime definition is also compiled (may be fixed if needed by adding a separate __ARCH_WANT_SYS_STIME macro, and defining it for all arch's defining __ARCH_WANT_SYS_TIME except x86_64).

The current value was correct before the introduction of Intel EM64T support - but now L1_CACHE_SHIFT_MAX can be less than L1_CACHE_SHIFT, which _is_ funny! Between the few users of ____cacheline_maxaligned_in_smp, we also have (for example) rcu_ctrlblk, and struct zone, with zone->{lru_,}lock. I.e. we have a lot of excess cacheline bouncing on them. No correctness issues, obviously. So this could even be merged for 2.6.14 (I'm not a fan of this idea, though). CC: Andi Kleen <ak@suse.de> Signed-off-by: -

B stepping were the first shipping Opterons. memcpy/memset/copy_page/ clear_page had special optimized version for them. These are really old and in the minority now and the difference to the generic versions (using rep microcode) is not that big anyways. So just remove them.

Fields obtained through cpuid vector 0x1(ebx[16:23]) and vector 0x4(eax[14:25], eax[26:31]) indicate the maximum values and might not always be the same as what is available and what OS sees. So make sure "siblings" and "cpu cores" values in /proc/cpuinfo reflect the values as seen by OS instead of what cpuid instruction says. This will also fix the buggy BIOS cases (for example where cpuid on a single core cpu says there are "2" siblings, even when HT is disabled in the BIOS. http://bugzilla.kernel.org/show_bug.cgi?id=4359) Signed-off-by:

When they were disabled before (e.g. after a panic) it's better to keep them off, otherwise followon panics can happen from timer interrupt handlers etc. Drawback is that pageup in the console won't work anymore though. Signed-off-by:

They report 40bit, but only have 36bits of physical address space. This caused problems with setting up the correct masks for MTRR. CPUID workaround for steppings 0F33h(supporting x86) and 0F34h(supporting x86 and EM64T).

Compute the highest possible value for memnode_shift, in order to reduce footprint of memnodemap[] to the minimum, thus making all users (phys_to_nid(), kfree()), more cache friendly. Before the patch : Node 0 MemBase 0000000000000000 Limit 00000001ffffffff Node 1 MemBase 0000000200000000 Limit 00000003ffffffff Using 23 for the hash shift. Max adder is 3ffffffff After the patch : Node 0 MemBase 0000000000000000 Limit 00000001ffffffff Node 1 MemBase 0000000200000000 Limit 00000003ffffffff Using 33 for the hash shift. In this case, only 2 bytes of memnodemap[] are used, instead of 2048 Signed-off-by:

With a NR_CPUS==128 kernel with CPU hotplug enabled we would waste 4MB on per CPU data of all possible CPUs. The reason was that HOTPLUG always set up possible map to NR_CPUS cpus and then we need to allocate that much (each per CPU data is roughly ~32k now) The underlying problem is that ACPI didn't tell us how many hotplug CPUs the platform supports. So the old code just assumed all, which would lead to this memory wastage. This implements some new heuristics: - If the BIOS specified disabled CPUs in the ACPI/mptables assume they can be enabled later (this is bending the ACPI specification a bit, but seems like a obvious extension) - The user can overwrite it with a new additionals_cpus=NUM option - Otherwise use half of the available CPUs or 2, whatever is more.

We should zap the low mappings, as soon as possible, so that we can catch kernel bugs more effectively. Previously early boot had NULL mapped and didn't trap on NULL references. This patch introduces boot_level4_pgt, which will always have low identity addresses mapped. Druing boot, all the processors will use this as their level4 pgt. On BP, we will switch to init_level4_pgt as soon as we enter C code and zap the low mappings as soon as we are done with the usage of identity low mapped addresses. On AP's we will zap the low mappings as soon as we jump to C code. Signed-off-by:
