2014-07-29sfc: Use __iowrite64_copy instead of a slightly different local functionBen Hutchings
__iowrite64_copy() isn't quite the same as efx_memcpy_64(), but it looks close enough: - The length is in units of qwords not bytes - It never byte-swaps, but that doesn't make a difference now as PIO is only enabled for x86_64 - It doesn't include any memory barriers, but that's OK as there is a barrier just before pushing the doorbell - mlx4_en uses it for the same purpose Compile-tested only.

2014-07-30ACPI / PNP: Fix acpi_pnp_match()Rafael J. Wysocki
The acpi_pnp_match() function is used for finding the ACPI device object that should be associated with the given PNP device. Unfortunately, the check used by that function is not strict enough and may cause success to be returned for a wrong ACPI device object. To fix that, use the observation that the pointer to the ACPI device object in question is already stored in the data field in struct pnp_dev, so acpi_pnp_match() can simply use that field to do its job. This problem was uncovered in 3.14 by commit 202317a573b2 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace).

2014-07-29ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from ↵Uwe Kleine-König
<mach/memory.h> The platforms selecting NEED_MACH_MEMORY_H defined the start address of their physical memory in the respective <mach/memory.h>. With ARM_PATCH_PHYS_VIRT=y (which is quite common today) this is useless though because the definition isn't used but determined dynamically. So remove the definitions from all <mach/memory.h> and provide the Kconfig symbol PHYS_OFFSET with the respective defaults in case ARM_PATCH_PHYS_VIRT isn't enabled. This allows to drop the dependency of PHYS_OFFSET on !NEED_MACH_MEMORY_H which prevents compiling an integrator nommu-kernel. (CONFIG_PAGE_OFFSET which has "default PHYS_OFFSET if !MMU" expanded to "0x" because CONFIG_PHYS_OFFSET doesn't exist as INTEGRATOR selects NEED_MACH_MEMORY_H.)

2014-07-29net: phy: re-apply PHY fixups during phy_register_deviceFlorian Fainelli
Commit 87aa9f9c61ad ("net: phy: consolidate PHY reset in phy_init_hw()") moved the call to phy_scan_fixups() in phy_init_hw() after a software reset is performed. By the time phy_init_hw() is called in phy_device_register(), no driver has been bound to this PHY yet, so all the checks in phy_init_hw() against the PHY driver and the PHY driver's config_init function will return 0. We will therefore never call phy_scan_fixups() as we should. Fix this by calling phy_scan_fixups() and check for its return value to restore the intended functionality. This broke PHY drivers which do register an early PHY fixup callback to intercept the PHY probing and do things like changing the 32-bits unique PHY identifier when a pseudo-PHY address has been used, as well as board-specific PHY fixups that need to be applied during driver probe time.

After this report there was no usual "Unable to handle kernel NULL pointer dereference" and this gave me a clue that address 0 is mapped and contains valid socket address structure in it. This bug was introduced in f3d3342602f8bcbf37d7c46641cb9bca7618eb1c (net: rework recvmsg handler msg_name and msg_namelen logic). Commit message states that: "Set msg->msg_name = NULL if user specified a NULL in msg_name but had a non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't affect sendto as it would bail out earlier while trying to copy-in the address." But in fact this affects sendto when address 0 is mapped and contains socket address structure in it. In such case copy-in address will succeed, verify_iovec() function will successfully exit with msg->msg_namelen > 0 and msg->msg_name == NULL. This patch fixes it by setting msg_namelen to 0 if msg_name == NULL.

2014-07-29Merge branch 'syststamp-removal'David S. Miller
Willem de Bruijn says: ==================== net: remove deprecated syststamp The network stack can generate two kinds of hardware timestamps: - hwtstamp stores a hw timestamp in device-specific raw format - syststamp convers the raw format to system time The second is deprecated and only implemented by a single device driver. The suggested alternative is to communicate hwtstamp + directly expose the NIC PTP clock device through ptp_clock_info. The remaining driver (octeon) does not expose such a standard interface as of now. It does have its own PTP library that depends on its own shared memory PTP clock interface. This patchset 1. reverts the syststamp code in the one driver (octeon) 2. reverts an unnecessary zero initialization in another (vxge) 3. modifies PF_PACKET to use syststamp is != 0 (because always == 0) 4. modifies SCM_TIMESTAMPING in the same way For backwards compatibility, the interfaces are not removed. Applications can still request SOF_TIMESTAMPING_SYS_HARDWARE. The response field in scm_timestamping also remains. As was the case for hardware/drivers that did not implement the feature, the setsockopt succeeds, but the response field is always zero. ==================== Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

2014-07-29net: remove deprecated syststamp timestampWillem de Bruijn
The SO_TIMESTAMPING API defines three types of timestamps: software, hardware in raw format (hwtstamp) and hardware converted to system format (syststamp). The last has been deprecated in favor of combining hwtstamp with a PTP clock driver. There are no active users in the kernel. The option was device driver dependent. If set, but without hardware support, the correct behavior is to return zero in the relevant field in the SCM_TIMESTAMPING ancillary message. Without device drivers implementing the option, this field is effectively always zero. Remove the internal plumbing to dissuage new drivers from implementing the feature. Keep the SOF_TIMESTAMPING_SYS_HARDWARE flag, however, to avoid breaking existing applications that request the timestamp. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

2014-07-29brcmfmac: Fix OOB interrupt not working for BCM43362Hans de Goede
It has taken me a long long time to get the OOB interrupt working on the AP6210 sdio wifi/bt module found on various Allwinner A20 boards. In the end I found these magic register pokes in the cubietruck kernel tree: https://github.com/cubieboard2/linux-sunxi/commit/7f08ba395617d17e7a711507503d89a50406fe7a This is also done for the bcm43362 in broadcom's internal/proprietary driver.
