2009-09-03x86, sched: Workaround broken sched domain creation for AMD Magny-CoursAndreas Herrmann
Current sched domain creation code can't handle multi-node processors. When switching to power_savings scheduling errors show up and system might hang later on (due to broken sched domain hierarchy): # echo 0 >> /sys/devices/system/cpu/sched_mc_power_savings CPU0 attaching sched-domain: domain 0: span 0-5 level MC groups: 0 1 2 3 4 5 domain 1: span 0-23 level NODE groups: 0-5 6-11 18-23 12-17 ... # echo 1 >> /sys/devices/system/cpu/sched_mc_power_savings CPU0 attaching sched-domain: domain 0: span 0-11 level MC groups: 0 1 2 3 4 5 6 7 8 9 10 11 ERROR: parent span is not a superset of domain->span domain 1: span 0-5 level CPU ERROR: domain->groups does not contain CPU0 groups: 6-11 (__cpu_power = 12288) ERROR: groups don't span domain->span domain 2: span 0-23 level NODE groups: ERROR: domain->cpu_power not set ERROR: groups don't span domain->span ... Fixing all aspects of power-savings scheduling for Magny-Cours needs some larger changes in the sched domain creation code. As a short-term and temporary workaround avoid the problems by extending "the worst possible hack" ;-( and always use llc_shared_map on AMD Magny-Cours when MC domain span is calculated. With this I get: # echo 1 >> /sys/devices/system/cpu/sched_mc_power_savings CPU0 attaching sched-domain: domain 0: span 0-5 level MC groups: 0 1 2 3 4 5 domain 1: span 0-5 level CPU groups: 0-5 (__cpu_power = 6144) domain 2: span 0-23 level NODE groups: 0-5 (__cpu_power = 6144) 6-11 (__cpu_power = 6144) 18-23 (__cpu_power = 6144) 12-17 (__cpu_power = 6144) ... I.e. no errors during sched domain creation, no system hangs, and also mc_power_savings scheduling works to a certain extend.

2009-09-03x86, mcheck: Use correct cpumask for shared bank4Andreas Herrmann
This fixes threshold_bank4 support on multi-node processors. The correct mask to use is llc_shared_map, representing an internal node on Magny-Cours. We need to create 2 sets of symlinks for sibling shared banks -- one set for each internal node, symlinks of each set should target the first core on same internal node. Currently only one set is created where all symlinks are targeting the first core of the entire socket. Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> Signed-off-by: H.

2009-08-21Re-introduce page mapping check in mark_buffer_dirty()Linus Torvalds
In commit a8e7d49aa7be728c4ae241a75a2a124cdcabc0c5 ("Fix race in create_empty_buffers() vs __set_page_dirty_buffers()"), I removed a test for a NULL page mapping unintentionally when some of the code inside __set_page_dirty() was moved to the callers. That removal generally didn't matter, since a filesystem would serialize truncation (which clears the page mapping) against writing (which marks the buffer dirty), so locking at a higher level (either per-page or an inode at a time) should mean that the buffer page would be stable. And indeed, nothing bad seemed to happen. Except it turns out that apparently reiserfs does something odd when under load and writing out the journal, and we have a number of bugzilla entries that look similar: http://bugzilla.kernel.org/show_bug.cgi?id=13556 http://bugzilla.kernel.org/show_bug.cgi?id=13756 http://bugzilla.kernel.org/show_bug.cgi?id=13876 and it looks like reiserfs depended on that check (the common theme seems to be "data=journal", and a journal writeback during a truncate). I suspect reiserfs should have some additional locking, but in the meantime this should get us back to the pre-2.6.29 behavior.

2009-08-21x86: don't call '->send_IPI_mask()' with an empty maskLinus Torvalds
As noted in 83d349f35e1ae72268c5104dbf9ab2ae635425d4 ("x86: don't send an IPI to the empty set of CPU's"), some APIC's will be very unhappy with an empty destination mask. That commit added a WARN_ON() for that case, and avoided the resulting problem, but didn't fix the underlying reason for why those empty mask cases happened. This fixes that, by checking the result of 'cpumask_andnot()' of the current CPU actually has any other CPU's left in the set of CPU's to be sent a TLB flush, and not calling down to the IPI code if the mask is empty. The reason this started happening at all is that we started passing just the CPU mask pointers around in commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), and when we did that, the cpumask was no longer thread-local. Before that commit, flush_tlb_mm() used to create it's own copy of 'mm->cpu_vm_mask' and pass that copy down to the low-level flush routines after having tested that it was not empty. But after changing it to just pass down the CPU mask pointer, the lower level TLB flush routines would now get a pointer to that 'mm->cpu_vm_mask', and that could still change - and become empty - after the test due to other CPU's having flushed their own TLB's. See http://bugzilla.kernel.org/show_bug.cgi?id=13933 for details.

2009-08-21Make bitmask 'and' operators return a result codeLinus Torvalds
When 'and'ing two bitmasks (where 'andnot' is a variation on it), some cases want to know whether the result is the empty set or not. In particular, the TLB IPI sending code wants to do cpumask operations and determine if there are any CPU's left in the final set. So this just makes the bitmask (and cpumask) functions return a boolean for whether the result has any bits set.

2009-08-21x86: don't send an IPI to the empty set of CPU'sLinus Torvalds
The default_send_IPI_mask_logical() function uses the "flat" APIC mode to send an IPI to a set of CPU's at once, but if that set happens to be empty, some older local APIC's will apparently be rather unhappy. So just warn if a caller gives us an empty mask, and ignore it. This fixes a regression in 2.6.30.x, due to commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), documented here: http://bugzilla.kernel.org/show_bug.cgi?id=13933 which causes a silent lock-up. It only seems to happen on PPro, P2, P3 and Athlon XP cores. Most developers sadly (or not so sadly, if you're a developer..) have more modern CPU's. Also, on x86-64 we don't use the flat APIC mode, so it would never trigger there even if the APIC didn't like sending an empty IPI mask.

Node may not be inserted over existing node. This causes inode tree corruption and I was seeing crashes in inode_tree_del which I can not reproduce after this patch.

There are many variants of Toshiba laptops with ALC268 codec, and it seems that a few of them don't work with model=toshiba preset since they have the secondary ALC268 codec just for HDMI output. This is a regression due to the previous clean-up work to merge all Toshiba quirk entries into a single check. This patch adds the identification of such laptops to apply the standard BIOS-probing method. Unfortunately, Toshiba laptops have all the same PCI SSID, so we need to check the codec SSID to identify each device.
