2014-07-25x86_64/vsyscall: Fix warn_bad_vsyscall log outputAndy Lutomirski
This commit in Linux 3.6: commit c767a54ba0657e52e6edaa97cbe0b0a8bf1c1655 Author: Joe Perches <joe@perches.com> Date: Mon May 21 19:50:07 2012 -0700 x86/debug: Add KERN_<LEVEL> to bare printks, convert printks to pr_<level> caused warn_bad_vsyscall to output garbage in the middle of the line. Revert the bad part of it. The printk in question isn't actually bare; the level is "%s". The bug this fixes is purely cosmetic; backports are optional.

2014-07-25clk: Support for clock parents and rates assigned from device treeSylwester Nawrocki
This patch adds helper functions to configure clock parents and rates as specified through 'assigned-clock-parents', 'assigned-clock-rates' DT properties for a clock provider or clock consumer device. The helpers are now being called by the bus code for the platform, I2C and SPI busses, before the driver probing and also in the clock core after registration of a clock provider.

2014-07-25x86/platform: New Intel Atom SOC power management controller driverLi, Aubrey
The Power Management Controller (PMC) controls many of the power management features present in the Atom SoC. This driver provides a native power off function via PMC PCI IO port. On some ACPI hardware-reduced platforms(e.g. ASUS-T100), ACPI sleep registers are not valid so that (*pm_power_off)() is not hooked by acpi_power_off(). The power off function in this driver is installed only when pm_power_off is NULL.

Legend: f - 8 freed bytes r - 8 redzone bytes . - 8 allocated bytes x=1..7 - x allocated bytes + (8-x) redzone bytes Investigation shows, that f2fs_evict_inode, when called for 'meta_inode', uses invalidate_mapping_pages() for 'node_inode'. But 'node_inode' is deleted before 'meta_inode' in f2fs_put_super via iput(). It seems that in common usage scenario this use-after-free is benign, because 'node_inode' remains partially valid data even after kmem_cache_free(). But things may change if, while 'meta_inode' is evicted in one f2fs filesystem, another (mounted) f2fs filesystem requests inode from cache, and formely 'node_inode' of the first filesystem is returned." Nids for both meta_inode and node_inode are reservation, so it's not necessary for us to invalidate pages which will never be allocated. To fix this issue, let's skipping needlessly invalidating pages for {meta,node}_inode in f2fs_evict_inode.

Ezequiel Garcia says: ==================== net: phy: Prevent an MDIO bus from being unloaded while in use Changes from v1: * Dropped the unneeded module_put() on phy_attach_direct(). The motivation of this small series is to fix the current lack of relationship between an ethernet driver and the MDIO bus behind the PHY device. In such cases, we would find no visible link between the drivers: $ lsmod Module Size Used by Not tainted mvmdio 2941 0 mvneta 22069 0 Which means nothing prevents the MDIO driver from being removed: $ modprobe -r mvmdio # Unable to handle kernel NULL pointer dereference at virtual address 00000060 pgd = c0004000 [00000060] *pgd=00000000 Internal error: Oops: 17 [#1] SMP ARM Modules linked in: mvneta [last unloaded: mvmdio] CPU: 0 PID: 22 Comm: kworker/0:1 Not tainted 3.16.0-rc5-01127-g62c0816-dirty #608 Workqueue: events_power_efficient phy_state_machine task: df5ec840 ti: df67a000 task.ti: df67a000 PC is at phy_state_machine+0x1c/0x468 LR is at phy_state_machine+0x18/0x468 [snip] This patchset fixes this problem by adding a pair of module_{get,put}, so the module reference count is increased when the PHY device is attached and is decreased when the PHY is detached. Tested with mvneta and mv643xx_eth drivers, which depend on the mvmdio driver to handle MDIO. This series applies on both net and net-next branches. ==================== Signed-off-by: David S.

2014-07-24net: phy: Ensure the MDIO bus module is heldEzequiel Garcia
This commit adds proper module_{get,put} to prevent the MDIO bus module from being unloaded while the phydev is connected. By doing so, we fix a kernel panic produced when a MDIO driver is removed, but the phydev that relies on it is attached and running.

2014-07-24net: phy: Set the driver when registering an MDIO bus deviceEzequiel Garcia
mdiobus_register() registers a device which is already bound to a driver. Hence, the driver pointer should be set properly in order to track down the driver associated to the MDIO bus. This will be used to allow ethernet driver to pin down a MDIO bus driver, preventing it from being unloaded while the PHY device is running.

2014-07-24x86: Merge tag 'ras_urgent' into x86/urgentH. Peter Anvin
Promote one fix for 3.16 This fix was necessary after 9c15a24b038f ("x86/mce: Improve mcheck_init_device() error handling") went in. What this patch did was, among others, check the return value of misc_register and exit early if it encountered an error. Original code sloppily didn't do that. However, cef12ee52b05 ("xen/mce: Add mcelog support for Xen platform") made it so that xen's init routine xen_late_init_mcelog runs first. This was needed for the xen mcelog device which is supposed to be independent from the baremetal one. Initially it was reported that misc_register() fails often on xen and that's why it needed fixing. However, it is *supposed* to fail by design, when running in dom0 so that the xen mcelog device file gets registered first. And *then* you need the notifier *not* unregistered on the error path so that the timer does get deleted properly in the CPU hotplug notifier. Btw, this fix is needed also on baremetal in the unlikely event that misc_register(&mce_chrdev_device) fails there too. I was unsure whether to rush it in now and decided to delay it to 3.17. However, xen people wanted it promoted as it breaks xen when doing cpu hotplug there. So, after a bit of simmering in tip/master for initial smoke testing, let's move it to 3.16. It fixes a semi-regression which got introduced in 3.16 so no need for stable tagging. tip/x86/ras contains that exact same commit but we can't remove it there as it is not the last one. It won't cause any merge issues, as I confirmed locally but I should state here the special situation of this one fix explicitly anyway. Thanks. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
