The "Type 2" SMBIOS record that contains Board Name is not strictly required and may be absent in the SMBIOS on some platforms. ( Please note that Type 2 is not listed in Table 3 in Sec 6.2 ("Required Structures and Data") of the SMBIOS v2.7 Specification. ) Use the Manufacturer Name (aka System Vendor) name. Print Board Name only when it is present. Before the fix: (i) dmesg output: DMI: /ProLiant DL380 G6, BIOS P62 01/29/2011 (ii) oops output: Pid: 2170, comm: bash Not tainted 2.6.38-rc4+ #3 /ProLiant DL380 G6 After the fix: (i) dmesg output: DMI: HP ProLiant DL380 G6, BIOS P62 01/29/2011 (ii) oops output: Pid: 2278, comm: bash Not tainted 2.6.38-rc4+ #4 HP ProLiant DL380 G6 Signed-off-by:

mp_find_ioapic() prints errors like: ERROR: Unable to locate IOAPIC for GSI 13 if it can't find the IOAPIC that manages that specific GSI. I see errors like that at every boot of a laptop that apparently doesn't have any IOAPICs. But if there are no IOAPICs it doesn't seem to be an error that none can be found. A solution that gets rid of this message is to directly return if nr_ioapics (still) is zero. (But keep returning -1 in that case, so nothing breaks from this change.) The call chain that generates this error is: pnpacpi_allocated_resource() case ACPI_RESOURCE_TYPE_IRQ: pnpacpi_parse_allocated_irqresource() acpi_get_override_irq() mp_find_ioapic() Signed-off-by:

Additionally doing things conditionally upon smp_processor_id() being zero is generally a bad idea, as this means CPU 0 cannot be offlined and brought back online later again. While there may be other places where this is done, I think adding more of those should be avoided so that some day SMP can really become "symmetrical". Signed-off-by:

In prepare_kernel_cred() since 2.6.29, put_cred(new) is called without assigning new->usage when security_prepare_creds() returned an error. As a result, memory for new and refcount for new->{user,group_info,tgcred} are leaked because put_cred(new) won't call __put_cred() unless old->usage == 1. Fix these leaks by assigning new->usage (and new->subscribers which was added in 2.6.32) before calling security_prepare_creds(). Signed-off-by:

In cred_alloc_blank() since 2.6.32, abort_creds(new) is called with new->security == NULL and new->magic == 0 when security_cred_alloc_blank() returns an error. As a result, BUG() will be triggered if SELinux is enabled or CONFIG_DEBUG_CREDENTIALS=y. If CONFIG_DEBUG_CREDENTIALS=y, BUG() is called from __invalid_creds() because cred->magic == 0. Failing that, BUG() is called from selinux_cred_free() because selinux_cred_free() is not expecting cred->security == NULL. This does not affect smack_cred_free(), tomoyo_cred_free() or apparmor_cred_free(). Fix these bugs by (1) Set new->magic before calling security_cred_alloc_blank(). (2) Handle null cred->security in creds_are_invalid() and selinux_cred_free(). Signed-off-by:

The AACI TRM requires the MAINCR enable bit to be held zero for two bitclk cycles plus three apb_pclk cycles. Use a delay of 1us to ensure this. Ensure that writes to MAINCR to change the addressed codec only happen when required, and that they take effect in a similar manner to the above, otherwise we seem to occasionally have stuck slot busy bits.

We reserve lowmem for the things that need it, like the ACPI wakeup code, way early to guarantee availability. This happens before we set up the proper pagetables, so set_memory_x() has no effect. Until we have a better solution, use an initcall to mark the wakeup code executable. Originally-by:

Spinlocks on shared processor partitions use H_YIELD to notify the hypervisor we are waiting on another virtual CPU. Unfortunately this means the hcall tracepoints can recurse. The patch below adds a percpu depth and checks it on both the entry and exit hcall tracepoints. Signed-off-by:

When converting to the new cpumask code I screwed up: - if (cpu_isset(cpu, numa_cpumask_lookup_table[node])) { - cpu_clear(cpu, numa_cpumask_lookup_table[node]); + if (cpumask_test_cpu(cpu, node_to_cpumask_map[node])) { + cpumask_set_cpu(cpu, node_to_cpumask_map[node]); This was introduced in commit 25863de0 (powerpc/cpumask: Convert NUMA code to new cpumask API) Fix it.

The hypervisor uses unsigned 1 byte counters to signal topology changes to the OS. Since they can wrap we need to check for any difference, not just if the hypervisor count is greater than the previous count. Signed-off-by:

VPHN supports up to 8 distance fields but the number of entries in ibm,associativity-reference-points signifies how many are in use. Don't look at all the VPHN counts, only distance_ref_points_depth worth. Since we already cap our distance metrics at MAX_DISTANCE_REF_POINTS, use that to size the VPHN arrays and add a BUILD_BUG_ON to avoid it growing larger than the VPHN maximum of 8. Signed-off-by:

Some of those functions try to adjust the CPU features, for example to remove NAP support on some revisions. However, they seem to use r5 as an index into the CPU table entry, which might have been right a long time ago but no longer is. r4 is the right register to use. This probably caused some off behaviours on some PowerMac variants using 750cx or 7455 processor revisions. Signed-off-by:

When calling setup_cpu() on 64-bit, we pass a pointer to the cputable entry we have found. This used to be fine when cur_cpu_spec was a pointer to that entry, but nowadays, we copy the entry into a separate variable, and we do so before we call the setup_cpu() callback. That means that any attempt by that callback at patching the CPU table entry (to adjust CPU features for example) will patch the wrong table. Signed-off-by:
