825600c x86: fix boot on uniprocessor systems On x86 uniprocessor systems topology_physical_package_id() returns -1 which causes rapl_cpu_prepare() to leave rapl_pmu variable uninitialized which leads to GPF in rapl_pmu_init(). See arch/x86/kernel/cpu/perf_event_intel_rapl.c. It turns out that physical_package_id and core_id can actually be retreived for uniprocessor systems too. Enabling them also fixes rapl_pmu code.

f217c44 Merge tag 'trace-fixes-v3.14-rc7-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "While on my flight to Linux Collaboration Summit, I was working on my slides for the event trigger tutorial. I booted a 3.14-rc7 kernel to perform what I wanted to teach and cut and paste it into my slides. When I tried the traceon event trigger with a condition attached to it (turns tracing on only if a field of the trigger event matches a condition set by the user), nothing happened. Tracing would not turn on. I stopped working on my presentation in order to find what was wrong. It ended up being the way trace event triggers work when they have conditions. Instead of copying the fields, the condition code just looks at the fields that were copied into the ring buffer. This works great, unless tracing is off. That's because when the event is reserved on the ring buffer, the ring buffer returns a NULL pointer, this tells the tracing code that the ring buffer is disabled. This ends up being a problem for the traceon trigger if it is using this information to check its condition. Luckily the code that checks if tracing is on returns the ring buffer to use (because the ring buffer is determined by the event file also passed to that field). I was able to easily solve this bug by checking in that helper function if the returned ring buffer entry is NULL, and if so, also check the file flag if it has a trace event trigger condition, and if so, to pass back a temp ring buffer to use. This will allow the trace event trigger condition to still test the event fields, but nothing will be recorded" * tag 'trace-fixes-v3.14-rc7-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix traceon trigger condition to actually turn tracing on 26 March 2014, 16:09:18 UTC
2c4a33a tracing: Fix traceon trigger condition to actually turn tracing on While working on my tutorial for 2014 Linux Collaboration Summit I found that the traceon trigger did not work when conditions were used. The other triggers worked fine though. Looking into it, it is because of the way the triggers use the ring buffer to store the fields it will use for the condition. But if tracing is off, nothing is stored in the buffer, and the tracepoint exits before calling the trigger to test the condition. This is fine for all the triggers that only work when tracing is on, but for traceon trigger that is to work when tracing is off, nothing happens. The fix is simple, just use a temp ring buffer to record the event if tracing is off and the event has a trace event conditional trigger enabled. The rest of the tracepoint code will work just fine, but the tracepoint wont be recorded in the other buffers.

5926f87 Revert "xen: properly account for _PAGE_NUMA during xen pte translations" This reverts commit a9c8e4beeeb64c22b84c803747487857fe424b68. PTEs in Xen PV guests must contain machine addresses if _PAGE_PRESENT is set and pseudo-physical addresses is _PAGE_PRESENT is clear. This is because during a domain save/restore (migration) the page table entries are "canonicalised" and uncanonicalised". i.e., MFNs are converted to PFNs during domain save so that on a restore the page table entries may be rewritten with the new MFNs on the destination. This canonicalisation is only done for PTEs that are present. This change resulted in writing PTEs with MFNs if _PAGE_PROTNONE (or _PAGE_NUMA) was set but _PAGE_PRESENT was clear. These PTEs would be migrated as-is which would result in unexpected behaviour in the destination domain. Either a) the MFN would be translated to the wrong PFN/page; b) setting the _PAGE_PRESENT bit would clear the PTE because the MFN is no longer owned by the domain; or c) the present bit would not get set. Symptoms include "Bad page" reports when munmapping after migrating a domain.

09ed3d5 xen/balloon: flush persistent kmaps in correct position Xen balloon driver will update ballooned out pages' P2M entries to point to scratch page for PV guests. In 24f69373e2 ("xen/balloon: don't alloc page while non-preemptible", kmap_flush_unused was moved after updating P2M table. In that case for 32 bit PV guest we might end up with P2M X -----> S (S is mfn of balloon scratch page) M2P Y -----> X (Y is mfn in persistent kmap entry) kmap_flush_unused() iterates through all the PTEs in the kmap address space, using pte_to_page() to obtain the page. If the p2m and the m2p are inconsistent the incorrect page is returned. This will clear page->address on the wrong page which may cause subsequent oopses if that page is currently kmap'ed. Move the flush back between get_page and __set_phys_to_machine to fix this.

4b29dba vxlan: fix nonfunctional neigh_reduce() The VXLAN neigh_reduce() code is completely non-functional since check-in. Specific errors: 1) The original code drops all packets with a multicast destination address, even though neighbor solicitations are sent to the solicited-node address, a multicast address. The code after this check was never run. 2) The neighbor table lookup used the IPv6 header destination, which is the solicited node address, rather than the target address from the neighbor solicitation. So neighbor lookups would always fail if it got this far. Also for L3MISSes. 3) The code calls ndisc_send_na(), which does a send on the tunnel device. The context for neigh_reduce() is the transmit path, vxlan_xmit(), where the host or a bridge-attached neighbor is trying to transmit a neighbor solicitation. To respond to it, the tunnel endpoint needs to do a *receive* of the appropriate neighbor advertisement. Doing a send, would only try to send the advertisement, encapsulated, to the remote destinations in the fdb -- hosts that definitely did not do the corresponding solicitation. 4) The code uses the tunnel endpoint IPv6 forwarding flag to determine the isrouter flag in the advertisement. This has nothing to do with whether or not the target is a router, and generally won't be set since the tunnel endpoint is bridging, not routing, traffic. The patch below creates a proxy neighbor advertisement to respond to neighbor solicitions as intended, providing proper IPv6 support for neighbor reduction.

866b7cd Merge branch 'davinci_emac' Christian Riesch says: ==================== net: davinci_emac: Fix interrupt requests and error handling since commit 6892b41d9701283085b655c6086fb57a5d63fa47 (Linux 3.11) the davinci_emac driver is broken. After doing ifconfig down, ifconfig up, requesting the interrupts for the driver fails. The interface remains dead until the board is rebooted. The first patch in this patchset reverts commit 6892b41d9701283085b655c6086fb57a5d63fa47 partially and makes the driver useable again. During the work on the first patch, a number of bugs in the error handling of the driver's ndo_open code were found. The second patch fixes these bugs. I believe the first patch meets the rules for stable kernels, I therefore added the stable tag to this patch. The second patch is just cleanup, the code that is fixed by this patch is only executed in case of an error. ==================== Signed-off-by: David S.

cd11cf5 net: davinci_emac: Fix rollback of emac_dev_open() If an error occurs during the initialization in emac_dev_open() (the driver's ndo_open function), interrupts, DMA descriptors etc. must be freed. The current rollback code is buggy in several ways. 1) Freeing the interrupts. The current code will not free all interrupts that were requested by the driver. Furthermore, the code tries to do a platform_get_resource(priv->pdev, IORESOURCE_IRQ, -1) in its last iteration. This patch fixes these bugs. 2) Wrong order of err: and rollback: labels. If the setup of the PHY in the code fails, the interrupts that have been requested before are not freed: request irq if requesting irqs fails, goto rollback setup phy if phy setup fails, goto err return 0 rollback: free irqs err: This patch brings the code into the correct order. 3) The code calls napi_enable() and emac_int_enable(), but does not undo both in case of an error. This patch adds calls of emac_int_disable() and napi_disable() to the rollback code. 4) RX DMA descriptors are not freed in case of an error: Right before requesting the irqs, the function creates DMA descriptors for the RX channel. These RX descriptors are never freed when we jump to either rollback or err. This patch adds code for freeing the DMA descriptors in the case of an initialization error. This required a modification of cpdma_ctrl_stop() in davinci_cpdma.c: We must be able to call this function to free the DMA descriptors while the DMA channels are in IDLE state (before cpdma_ctlr_start() was called).

33b7107 net: davinci_emac: Replace devm_request_irq with request_irq In commit 6892b41d9701283085b655c6086fb57a5d63fa47 Author: Lad, Prabhakar <prabhakar.csengg@gmail.com> Date: Tue Jun 25 21:24:51 2013 +0530 net: davinci: emac: Convert to devm_* api the call of request_irq is replaced by devm_request_irq and the call of free_irq is removed. But since interrupts are requested in emac_dev_open, doing ifconfig up/down on the board requests the interrupts again each time, causing devm_request_irq to fail. The interface is dead until the device is rebooted. This patch reverts said commit partially: It changes the driver back to use request_irq instead of devm_request_irq, puts free_irq back in place, but keeps the remaining changes of the original patch.

cb3042d sparc64: Make sure %pil interrupts are enabled during hypervisor yield. In arch_cpu_idle() we must enable %pil based interrupts before potentially invoking the hypervisor cpu yield call. As per the Hypervisor API documentation for cpu_yield: Interrupts which are blocked by some mechanism other that pstate.ie (for example %pil) are not guaranteed to cause a return from this service. It seems that only first generation Niagara chips are hit by this bug. My best guess is that later chips implement this in hardware and wake up anyways from %pil events, whereas in first generation chips the yield is implemented completely in hypervisor code and requires %pil to be enabled in order to wake properly from this call.

b37199e rcuwalk: recheck mount_lock after mountpoint crossing attempts We can get false negative from __lookup_mnt() if an unrelated vfsmount gets moved. In that case legitimize_mnt() is guaranteed to fail, and we will fall back to non-RCU walk... unless we end up running into a hard error on a filesystem object we wouldn't have reached if not for that false negative. IOW, delaying that check until the end of pathname resolution is wrong - we should recheck right after we attempt to cross the mountpoint. We don't need to recheck unless we see d_mountpoint() being true - in that case even if we have just raced with mount/umount, we can simply go on as if we'd come at the moment when the sucker wasn't a mountpoint; if we run into a hard error as the result, it was a legitimate outcome. __lookup_mnt() returning NULL is different in that respect, since it might've happened due to operation on completely unrelated mountpoint.

99aea68 vfs: Don't let __fdget_pos() get FMODE_PATH files Commit bd2a31d522344 ("get rid of fget_light()") introduced the __fdget_pos() function, which returns the resulting file pointer and fdput flags combined in an 'unsigned long'. However, it also changed the behavior to return files with FMODE_PATH set, which shouldn't happen because read(), write(), lseek(), etc. aren't allowed on such files. This commit restores the old behavior. This regression actually had no effect on read() and write() since FMODE_READ and FMODE_WRITE are not set on file descriptors opened with O_PATH, but it did cause lseek() on a file descriptor opened with O_PATH to fail with ESPIPE rather than EBADF.

11d4616 futex: revert back to the explicit waiter counting code Srikar Dronamraju reports that commit b0c29f79ecea ("futexes: Avoid taking the hb->lock if there's nothing to wake up") causes java threads getting stuck on futexes when runing specjbb on a power7 numa box. The cause appears to be that the powerpc spinlocks aren't using the same ticket lock model that we use on x86 (and other) architectures, which in turn result in the "spin_is_locked()" test in hb_waiters_pending() occasionally reporting an unlocked spinlock even when there are pending waiters. So this reinstates Davidlohr Bueso's original explicit waiter counting code, which I had convinced Davidlohr to drop in favor of figuring out the pending waiters by just using the existing state of the spinlock and the wait queue.

7e09e73 mm: fix swapops.h:131 bug if remap_file_pages raced migration Add remove_linear_migration_ptes_from_nonlinear(), to fix an interesting little include/linux/swapops.h:131 BUG_ON(!PageLocked) found by trinity: indicating that remove_migration_ptes() failed to find one of the migration entries that was temporarily inserted. The problem comes from remap_file_pages()'s switch from vma_interval_tree (good for inserting the migration entry) to i_mmap_nonlinear list (no good for locating it again); but can only be a problem if the remap_file_pages() range does not cover the whole of the vma (zap_pte() clears the range). remove_migration_ptes() needs a file_nonlinear method to go down the i_mmap_nonlinear list, applying linear location to look for migration entries in those vmas too, just in case there was this race. The file_nonlinear method does need rmap_walk_control.arg to do this; but it never needed vma passed in - vma comes from its own iteration.

Modify irq_domain_ops for CIU and CIU2 to "gracefully handle" GPIO lines (neither return error code nor call octeon_irq_set_ciu_mapping for it). This should avoid the warning. (As before the real setup for GPIO lines will happen using irq_domain_ops of gpio-controller.) This patch is based on Wei's patch v2 (see http://marc.info/?l=linux-mips&m=139511814813247).

707d4ee Revert "[PATCH] Insert GART region into resource map" This reverts commit 56dd669a138c, which makes the GART visible in /proc/iomem. This fixes a regression: e501b3d87f00 ("agp: Support 64-bit APBASE") exposed an existing problem with a conflict between the GART region and a PCI BAR region. The GART addresses are bus addresses, not CPU addresses, and therefore should not be inserted in iomem_resource. On many machines, the GART region is addressable by the CPU as well as by an AGP master, but CPU addressability is not required by the spec. On some of these machines, the GART is mapped by a PCI BAR, and in that case, the PCI core automatically inserts it into iomem_resource, just as it does for all BARs. Inserting it here means we'll have a conflict if the PCI core later tries to claim the GART region, so let's drop the insertion here. The conflict indirectly causes X failures, as reported by Jouni in the bugzilla below. We detected the conflict even before e501b3d87f00, but after it the AGP code (fix_northbridge()) uses the PCI resource (which is zeroed because of the conflict) instead of reading the BAR again.

These errors resulted in the device and host disagreeing about shared settings, with complete failure to communicate as the end result. The NCM specification require that many of the NCM specific control reuests are sent only while the NCM Data Interface is in alternate setting 0. Reverting the commit ensures that we follow this requirement.

8d7f1fb ATHEROS-ALX: Use dma_set_mask_and_coherent and fix a bug 1. For the 64 bits dma mask use dma_set_mask_and_coherent instead of dma_set_mask and dma_set_coherent_mask. 2. For the 32 bits dma mask dma_set_coherent_mask is only called if dma_set_mask fails, which is unusual. Assuming this as a bug, fixes it by replacing calls to dma_set_mask and dma_set_coherent_mask by a call to dma_set_mask_and_coherent.

1535bd8 sparc64: don't treat 64-bit syscall return codes as 32-bit When checking a system call return code for an error, linux_sparc_syscall was sign-extending the lower 32-bit value and comparing it to -ERESTART_RESTARTBLOCK. lseek can return valid return codes whose lower 32-bits alone would indicate a failure (such as 4G-1). Use the whole 64-bit value to check for errors. Only the 32-bit path should sign extend the lower 32-bit value.

06e2e88 MIPS: mark O32+FP64 experimental for now Commit 597ce1723e0f "MIPS: Support for 64-bit FP with O32 binaries" introduced support for setting Status.FR=1 for O32 binaries with the EF_MIPS_FP64 ELF header flag set. Whilst this flag is currently supported by binutils it does introduce an ABI break within userland. Objects built with EF_MIPS_FP64 cannot be safely linked with those built without it since code in either object may assume behaviour specific to a value of FR. More recently there has been discussion around avoiding further fragmentation of the O32 ABI whilst still allowing the use of FR=1 and features such as MSA which depend upon it. Details of the plan to allow this are still being worked on, and whilst the kernel will need the ability to handle FR=1 with O32 tasks it is unclear what else it may need to provide to a userland which seeks to avoid another ABI break. In order to prevent the proliferation of userland which may rely upon the current EF_MIPS_FP64 behaviour this patch marks the kernel support for it experimental & disables it by default. Under current proposals it is likely that this support can simply be enabled again later, but possibly after the introduction of further interfaces with userland and support for the MIPS R5 UFR feature.

a8031d2 MIPS: asm: syscall: Fix copying system call arguments The syscall_get_arguments function expects the arguments to be copied to the '*args' argument but instead a local variable was used to hold the system call argument. As a result of which, this variable was never passed to the filter and any filter testing the system call arguments would fail. This is fixed by passing the '*args' variable as the destination memory for the system call arguments.
