There are currently no users of this API, let's remove it. Additionally, if such feature would be needed future wise, a better option is likely use pm_runtime_set_active|suspended() in some form.

2015-01-13x86/xen: properly retrieve NMI reasonJan Beulich1-0/+51
Using the native code here can't work properly, as the hypervisor would normally have cleared the two reason bits by the time Dom0 gets to see the NMI (if passed to it at all). There's a shared info field for this, and there's an existing hook to use - just fit the two together. This is particularly relevant so that NMIs intended to be handled by APEI / GHES actually make it to the respective handler. Note that the hook can (and should) be used irrespective of whether being in Dom0, as accessing port 0x61 in a DomU would be even worse, while the shared info field would just hold zero all the time. Note further that hardware NMI handling for PVH doesn't currently work anyway due to missing code in the hypervisor (but it is expected to work the native rather than the PV way).

2015-01-13mm: mmu_gather: use tlb->end != 0 only for TLB invalidationWill Deacon1-2/+6
When batching up address ranges for TLB invalidation, we check tlb->end != 0 to indicate that some pages have actually been unmapped. As of commit f045bbb9fa1b ("mmu_gather: fix over-eager tlb_flush_mmu_free() calling"), we use the same check for freeing these pages in order to avoid a performance regression where we call free_pages_and_swap_cache even when no pages are actually queued up. Unfortunately, the range could have been reset (tlb->end = 0) by tlb_end_vma, which has been shown to cause memory leaks on arm64. Furthermore, investigation into these leaks revealed that the fullmm case on task exit no longer invalidates the TLB, by virtue of tlb->end == 0 (in 3.18, need_flush would have been set). This patch resolves the problem by reverting commit f045bbb9fa1b, using instead tlb->local.nr as the predicate for page freeing in tlb_flush_mmu_free and ensuring that tlb->end is initialised to a non-zero value in the fullmm case.

2015-01-12mmc: sdhci: Disable re-tuning for HS400Adrian Hunter1-0/+1
Re-tuning for HS400 mode must be done in HS200 mode. Currently there is no support for that. That needs to be reflected in the code. Specifically, if tuning is executed in HS400 mode then return an error, and do not start the tuning timer if HS200 tuning is being done prior to switching to HS400. Note that periodic re-tuning is not expected to be needed for HS400 but re-tuning is still needed after the host controller has lost power. In the case of suspend/resume that is not necessary because the card is fully re-initialised. That just leaves runtime suspend/resume with no support for HS400 re-tuning.

2015-01-08vfs: renumber FMODE_NONOTIFY and add to uniqueness checkDavid Drysdale2-2/+2
Fix clashing values for O_PATH and FMODE_NONOTIFY on sparc. The clashing O_PATH value was added in commit 5229645bdc35 ("vfs: add nonconflicting values for O_PATH") but this can't be changed as it is user-visible. FMODE_NONOTIFY is only used internally in the kernel, but it is in the same numbering space as the other O_* flags, as indicated by the comment at the top of include/uapi/asm-generic/fcntl.h (and its use in fs/notify/fanotify/fanotify_user.c). So renumber it to avoid the clash. All of this has happened before (commit 12ed2e36c98a: "fanotify: FMODE_NONOTIFY and __O_SYNC in sparc conflict"), and all of this will happen again -- so update the uniqueness check in fcntl_init() to include __FMODE_NONOTIFY.

2015-01-08mm: protect set_page_dirty() from ongoing truncationJohannes Weiner1-1/+0
Tejun, while reviewing the code, spotted the following race condition between the dirtying and truncation of a page: __set_page_dirty_nobuffers() __delete_from_page_cache() if (TestSetPageDirty(page)) page->mapping = NULL if (PageDirty()) dec_zone_page_state(page, NR_FILE_DIRTY); dec_bdi_stat(mapping->backing_dev_info, BDI_RECLAIMABLE); if (page->mapping) account_page_dirtied(page) __inc_zone_page_state(page, NR_FILE_DIRTY); __inc_bdi_stat(mapping->backing_dev_info, BDI_RECLAIMABLE); which results in an imbalance of NR_FILE_DIRTY and BDI_RECLAIMABLE. Dirtiers usually lock out truncation, either by holding the page lock directly, or in case of zap_pte_range(), by pinning the mapcount with the page table lock held. The notable exception to this rule, though, is do_wp_page(), for which this race exists. However, do_wp_page() already waits for a locked page to unlock before setting the dirty bit, in order to prevent a race where clear_page_dirty() misses the page bit in the presence of dirty ptes. Upgrade that wait to a fully locked set_page_dirty() to also cover the situation explained above. Afterwards, the code in set_page_dirty() dealing with a truncation race is no longer needed. Remove it. Reported-by: Tejun Heo <tj@kernel.org> Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Acked-by: Kirill A.

2015-01-08mm: prevent endless growth of anon_vma hierarchyKonstantin Khlebnikov1-0/+10
Constantly forking task causes unlimited grow of anon_vma chain. Each next child allocates new level of anon_vmas and links vma to all previous levels because pages might be inherited from any level. This patch adds heuristic which decides to reuse existing anon_vma instead of forking new one. It adds counter anon_vma->degree which counts linked vmas and directly descending anon_vmas and reuses anon_vma if counter is lower than two. As a result each anon_vma has either vma or at least two descending anon_vmas. In such trees half of nodes are leafs with alive vmas, thus count of anon_vmas is no more than two times bigger than count of vmas. This heuristic reuses anon_vmas as few as possible because each reuse adds false aliasing among vmas and rmap walker ought to scan more ptes when it searches where page is might be mapped.

2015-01-06mm: propagate error from stack expansion even for guard pageLinus Torvalds1-1/+1
Jay Foad reports that the address sanitizer test (asan) sometimes gets confused by a stack pointer that ends up being outside the stack vma that is reported by /proc/maps. This happens due to an interaction between RLIMIT_STACK and the guard page: when we do the guard page check, we ignore the potential error from the stack expansion, which effectively results in a missing guard page, since the expected stack expansion won't have been done. And since /proc/maps explicitly ignores the guard page (commit d7824370e263: "mm: fix up some user-visible effects of the stack guard page"), the stack pointer ends up being outside the reported stack area. This is the minimal patch: it just propagates the error. It also effectively makes the guard page part of the stack limit, which in turn measn that the actual real stack is one page less than the stack limit. Let's see if anybody notices. We could teach acct_stack_growth() to allow an extra page for a grow-up/grow-down stack in the rlimit test, but I don't want to add more complexity if it isn't needed.

acpi_map_lsapic() will allocate a logical CPU number and map it to physical CPU id (such as APIC id) for the hot-added CPU, it will also do some mapping for NUMA node id and etc, acpi_unmap_lsapic() will do the reverse. We can see that the name of the function is a little bit confusing and arch (IA64) dependent so rename them as acpi_(un)map_cpu() to make arch agnostic and explicit.

2015-01-05ACPI / processor: Convert apic_id to phys_id to make it arch agnosticHanjun Guo1-4/+4
apic_id in MADT table is the CPU hardware id which identify it self in the system for x86 and ia64, OSPM will use it for SMP init to map APIC ID to logical cpu number in the early boot, when the DSDT/SSDT (ACPI namespace) is scanned later, the ACPI processor driver is probed and the driver will use acpi_id in DSDT to get the apic_id, then map to the logical cpu number which is needed by the processor driver. Before ACPI 5.0, only x86 and ia64 were supported in ACPI spec, so apic_id is used both in arch code and ACPI core which is pretty fine. Since ACPI 5.0, ARM is supported by ACPI and APIC is not available on ARM, this will confuse people when apic_id is both used by x86 and ARM in one function. So convert apic_id to phys_id (which is the original meaning) in ACPI processor dirver to make it arch agnostic, but leave the arch dependent code unchanged, no functional change.

This reverts commit ca34e3b5c808385b175650605faa29e71e91991b. It turns out that the p54 and cw2100 drivers assume that there's tailroom even when they don't say they really need it. However, there's currently no way for them to explicitly say they do need it, so for now revert this. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=90331.

The major fix here is to have proper sequencing between cpufreq layer and thermal cpu cooling registration. A take away of this fix is an improvement in the thermal drivers code.
