If NAPI is enabled while IPoIB's CQ is being drained, it creates a race on priv->ibwc between ipoib_poll() and ipoib_drain_cq(), leading to memory corruption. The solution is to enable/disable NAPI in ipoib_ib_dev_{open/stop}() instead of in ipoib_{open/stop}(), and sync NAPI on the INITIALIZED flag instead on the ADMIN_UP flag. This way NAPI will be disabled when ipoib_drain_cq() is called. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1587>.

notice one system /proc/iomem some entries missed the name for pci_devices it turns that dev->dev.kobj name is changed after device_add. for pci code: via acpi_pci_root_driver.ops.add (aka acpi_pci_root_add) ==> pci_acpi_scan_root is used to scan pci bus/device, and at the same time we read the resource for pci_dev in the pci_read_bases, we have res->name = pci_name(pci_dev); pci_name is calling dev_name. later via acpi_pci_root_driver.ops.start (aka acpi_pci_root_start) ==> pci_bus_add_device to add all pci_dev in kobj tree. pci_bus_add_device will call device_add. actually in device_add /* first, register with generic layer. */ error = kobject_add(&dev->kobj, dev->kobj.parent, "%s", dev_name(dev)); if (error) goto Error; will get one new name for that kobj, old name is freed.

In current code we register/unregister connector object by drm_sysfs_connector_add/remove function. However under some cases, we need to dynamically register or unregister device multiple times, so we have to go through register -> unregister ->register routine. Because after device_unregister function our memory is dirty, we need to do clean operation in order to re-register the device, otherwise the system will crash. The patch intends to clean device after device release. Signed-off-by: Ma Ling <ling.ma@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

Commit 900af0d9 (PM: Change suspend code ordering) changed the ordering of suspend code in such a way that the platform .prepare() callback is now executed after the device drivers' late suspend callbacks have run. Unfortunately, this turns out to break ARM platforms that need to talk via I2C to power control devices during the .prepare() callback. For this reason introduce two new platform suspend callbacks, .prepare_late() and .wake(), that will be called just prior to disabling non-boot CPUs and right after bringing them back on line, respectively, and use them instead of .prepare() and .finish() for ACPI suspend. Make the PM core execute the .prepare() and .finish() platform suspend callbacks where they were executed previously (that is, right after calling the regular suspend methods provided by device drivers and right before executing their regular resume methods, respectively). It is not necessary to make analogous changes to the hibernation code and data structures at the moment, because they are only used by ACPI platforms. Signed-off-by: Rafael J.

This reverts commit 1c55f187. Ingo Brueckl was assuming that reverting to 1:1 mapping for chars >= 128 was not useful, but it happens to be: due to the limitations of the Linux console, when a blind user wants to read BIG5 on it, he has no other way than loading a font without SFM and let the 1:1 mapping permit the screen reader to get the BIG5 encoding.

Since commit 0a1c01c9 ("Make relatime default") when a file system is mounted explicitely with noatime it gets both the MNT_RELATIME and MNT_NOATIME bits set. This shows up like this in /proc/mounts: /dev/xxx /yyy ext3 rw,noatime,relatime,errors=continue,data=writeback 0 0 That looks strange. The VFS uses noatime in this case, but both flags are set. So it's more a cosmetic issue, but still better to fix. Cc: mjg@redhat.com Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Fixes guest crash 'lguest: bad read address 0x4800000 len 256' The new per-cpu allocator ends up handing a non-linear address to write_gdt_entry. We do __pa() on it, and hand it to the host, which kills us. I've long wanted to make the hypercall "LOAD_GDT_ENTRY" to match the IDT code, but had no pressing reason until now.

Typical message: 'lguest: unhandled trap 6 at 0x418726 (0x0)' vmlinux guests were broken by 4cd8b5e2 'lguest: use KVM hypercalls', which rewrites guest text from kvm hypercalls to trap 31. The Launcher mmaps the kernel image. The Guest executes and immediately faults in the first text page (read-only). Then it hits a hypercall, and we rewrite that hypercall, causing a copy-on-write. But the Guest pagetables still refer to the old page: we fault again, but as Host we see the hypercall already rewritten, and pass the fault back to the Guest. The Guest hasn't set up an IDT yet, so we kill it. This doesn't happen with bzImages: they unpack themselves and so the text pages are already read-write.

Following patch introduce support for setting options to gcc that has effect for current directory and all subdirectories. The typical use case are an architecture or a subsystem that decide to cover all files with -Werror. Today alpha, mips and sparc uses -Werror in almost all their Makefile- with subdir-ccflag-y it is now simpler to do so as only the top-level directories needs to be covered. Likewise if we decide to cover a full subsystem such as net/ with -Werror this is done by adding a single line to net/Makefile.

We need a location for generated files. Today they are spread over several places and bringing them together to a common place makes it obvious hat is generated and what isreal files. Al Viro originally suggested: include/gen Linus suggested to spell it out. This patch implement support for include/generated All files in include/generated are ignored by git. include/generated is removed during "make mrproper". With this we are ready to implement support for include/generated in the various architctures and in the base kernel.

This function is not actually used right now, since the original use case for it was done with insert_resource_expand_to_fit() instead. However, we now have another usage case that wants to basically do a "reserve IO resource, splitting around existing resources", however that one doesn't actually want the "recurse into the conflicting resource" logic at all. And since recursing into the conflicting resource was the most complex part, and isn't wanted, just remove it. Maybe we'll some day want both versions, but we can just resurrect the logic then.
