| git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "It's the usual big pile of driver updates and additions, but we do have a couple core changes in here as well. Core: - CLK_IS_CRITICAL support has been added. This should allow drivers to properly express that a certain clk should stay on even if their prepare/enable count drops to 0 (and in turn the parents of these clks should stay enabled). - A clk registration API has been added, clk_hw_register(), and an OF clk provider API has been added, of_clk_add_hw_provider(). These APIs have been put in place to further split clk providers from clk consumers, with the goal being to have clk providers never deal with struct clk pointers at all. Conversion of provider drivers is on going. clkdev has also gained support for registering clk_hw pointers directly so we can convert drivers that don't use devicetree. New Drivers: - Marvell ap806 and cp110 system controllers (with clks inside!) - Hisilicon Hi3519 clock and reset controller - Axis ARTPEC-6 clock controllers - Oxford Semiconductor OXNAS clock controllers - AXS10X I2S PLL - Rockchip RK3399 clock and reset controller Updates: - MMC2 and UART2 clks on Samsung Exynos 3250, ACLK on Samsung Exynos 542x SoCs, and some more clk ID exporting for bus frequency scaling - Proper BCM2835 PCM clk support and various other clks - i.MX clk updates for i.MX6SX, i.MX7, and VF610 - Renesas updates for R-Car H3 - Tegra210 got updates for DisplayPort and HDMI 2.0 - Rockchip driver refactorings and fixes due to adding RK3399 support" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (139 commits) clk: fix critical clock locking clk: qcom: mmcc-8996: Remove clocks that should be controlled by RPM clk: ingenic: Allow divider value to be divided clk: sunxi: Add display and TCON0 clocks driver clk: rockchip: drop old_rate calculation on pll rate changes clk: rockchip: simplify GRF handling in pll clocks clk: rockchip: lookup General Register Files in rockchip_clk_init clk: rockchip: fix the rk3399 sdmmc sample / drv name clk: mvebu: new driver for Armada CP110 system controller dt-bindings: arm: add DT binding for Marvell CP110 system controller clk: mvebu: new driver for Armada AP806 system controller clk: hisilicon: add CRG driver for hi3519 soc clk: hisilicon: export some hisilicon APIs to modules reset: hisilicon: add reset controller driver for hisilicon SOCs clk: bcm/kona: Do not use sizeof on pointer type clk: qcom: msm8916: Fix crypto clock flags clk: nxp: lpc18xx: Initialize clk_init_data::flags to 0 clk/axs10x: Add I2S PLL clock driver clk: imx7d: fix ahb clock mux 1 clk: fix comment of devm_clk_hw_register() ... | |||

| 2016-05-20 | zram: introduce per-device debug_stat sysfs node | Sergey Senozhatsky | |
| debug_stat sysfs is read-only and represents various debugging data that zram developers may need. This file is not meant to be used by anyone else: its content is not documented and will change any time w/o any notice. Therefore, the output of debug_stat file contains a version string. To avoid any confusion, we will increase the version number every time we modify the output. At the moment this file exports only one value -- the number of re-compressions, IOW, the number of times compression fast path has failed. This stat is temporary any will be useful in case if any per-cpu compression streams regressions will be reported.

| 2016-05-20 | zram: remove max_comp_streams internals | Sergey Senozhatsky | |
| Remove the internal part of max_comp_streams interface, since we switched to per-cpu streams. We will keep RW max_comp_streams attr around, because: a) we may (silently) switch back to idle compression streams list and don't want to disturb user space b) max_comp_streams attr must wait for the next 'lay off cycle'; we give user space 2 years to adjust before we remove/downgrade the attr, and there are already several attrs scheduled for removal in 4.11, so it's too late for max_comp_streams. This slightly change a user visible behaviour: - First, reading from max_comp_stream file now will always return the number of online CPUs. - Second, writing to max_comp_stream will not take any effect.

| 2016-05-20 | zram: user per-cpu compression streams | Sergey Senozhatsky | |
| Remove idle streams list and keep compression streams in per-cpu data. This removes two contented spin_lock()/spin_unlock() calls from write path and also prevent write OP from being preempted while holding the compression stream, which can cause slow downs. For instance, let's assume that we have N cpus and N-2 max_comp_streams.TASK1 owns the last idle stream, TASK2-TASK3 come in with the write requests: TASK1 TASK2 TASK3 zram_bvec_write() spin_lock find stream spin_unlock compress <<preempted>> zram_bvec_write() spin_lock find stream spin_unlock no_stream schedule zram_bvec_write() spin_lock find_stream spin_unlock no_stream schedule spin_lock release stream spin_unlock wake up TASK2 not only TASK2 and TASK3 will not get the stream, TASK1 will be preempted in the middle of its operation; while we would prefer it to finish compression and release the stream. Test environment: x86_64, 4 CPU box, 3G zram, lzo The following fio tests were executed: read, randread, write, randwrite, rw, randrw with the increasing number of jobs from 1 to 10. 4 streams 8

| In case we find a socket with encapsulation enabled we should call the encap_recv function even if just a udp header without payload is available. The callbacks are responsible for correctly verifying and dropping the packets. Also, in case the header validation fails for geneve and vxlan we shouldn't put the skb back into the socket queue, no one will pick them up there. Instead we can simply discard them in the respective encap_recv functions. Signed-off-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S. Miller <davem@davemloft.net> | |||

| 2016-05-20 | tuntap: correctly wake up process during uninit | Jason Wang | |
| We used to check dev->reg_state against NETREG_REGISTERED after each time we are woke up. But after commit 9e641bdcfa4e ("net-tun: restructure tun_do_read for better sleep/wakeup efficiency"), it uses skb_recv_datagram() which does not check dev->reg_state. This will result if we delete a tun/tap device after a process is blocked in the reading. The device will wait for the reference count which was held by that process for ever. Fixes this by using RCV_SHUTDOWN which will be checked during sk_recv_datagram() before trying to wake up the process during uninit.

These are used to described IP in IP tunnel and what the outer protocol is. The inner protocol can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT are removed (these are both instances of SKB_GSO_IPXIP4). SKB_GSO_IPXIP6 will be used when support for GSO with IP encapsulation over IPv6 is added.

| 2016-05-20 | xen-netback: only deinitialized hash if it was initialized | Paul Durrant | |
| A domain with a frontend that does not implement a control ring has been seen to cause a crash during domain save. This was apparently because the call to xenvif_deinit_hash() in xenvif_disconnect_ctrl() is made regardless of whether a control ring was connected, and hence xenvif_hash_init() was called. This patch brings the call to xenvif_deinit_hash() in xenvif_disconnect_ctrl() inside the if clause that checks whether the control ring event channel was connected. This is sufficient to ensure it is only called if xenvif_init_hash() was called previously.

| The length checks on the grant table copy_ops for setting hash key and hash mapping are checking the local 'len' value which is correct in the case of the former but not the latter. This was picked up by static analysis checks.

| 2016-05-20 | phy: fix crash in fixed_phy_add() | Rabin Vincent | |
| Since e7f4dc3536a ("mdio: Move allocation of interrupts into core"), platforms which call fixed_phy_add() before fixed_mdio_bus_init() is called (for example, because the platform code and the fixed_phy driver use the same initcall level) crash in fixed_phy_add() since the ->mii_bus is not allocated. Also since e7f4dc3536a, these interrupts are initalized to polling by default. The few (old) platforms which directly use fixed_phy_add() from their platform code all pass PHY_POLL for the irq argument, so we can keep these platforms not crashing by simply not attempting to set the irq if PHY_POLL is passed. Also, even if problems have not been reported on more modern platforms which used fixed_phy_register() from drivers' probe functions, we return -EPROBE_DEFER if the MDIO bus is not yet registered so that the probe is retried later.

| 2016-05-19 | clk: fix critical clock locking | Maxime Ripard | |
| The critical clock handling in __clk_core_init isn't taking the enable lock before calling clk_core_enable, which in turns triggers the warning in the lockdep_assert_held call in that function when lockep is enabled. Add the calls to clk_enable_lock/unlock to make sure it doesn't happen.

Apart from that linear development, details below. Core changes: - Add the devm_pinctrl_register() API and switch all applicable drivers to use it, saving lots of lines of code all over the place. New drivers: - driver for the Broadcom NS2 SoC - subdriver for the PXA25x SoCs - subdriver for the AMLogic Meson GXBB SoC Driver improvements: - the Intel Baytrail driver now properly supports pin control - Nomadik, Rockchip, Broadcom BCM2835 support the .get_direction() callback in the GPIO portions - continued development and stabilization of several SH-PFC SoC subdrivers: r8a7795, r8a7790, r8a7794 etc" * tag 'pinctrl-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (85 commits) Revert "pinctrl: tegra: avoid parked_reg and parked_bank" pinctrl: meson: Fix eth_tx_en bit index pinctrl: tegra: avoid parked_reg and parked_bank pinctrl: tegra: Correctly check the supported configuration pinctrl: amlogic: Add support for Amlogic Meson GXBB SoC pinctrl: rockchip: fix pull setting error for rk3399 pinctrl: stm32: Implement .pin_config_dbg_show() pinctrl: nomadik: hide nmk_gpio_get_mode when unused pinctrl: ns2: rename pinctrl_utils_dt_free_map pinctrl: at91: Merge clk_prepare and clk_enable into clk_prepare_enable pinctrl: at91: Make at91_gpio_template const pinctrl: baytrail: fix some error handling in debugfs pinctrl: ns2: add pinmux driver support for Broadcom NS2 SoC pinctrl: sirf/atlas7: trivial fix of spelling mistake on flagged pinctrl: sh-pfc: Kill unused variable in sh_pfc_remove() pinctrl: nomadik: implement .get_direction() pinctrl: nomadik: use BIT() with offsets consequently pinctrl: exynos5440: Use off-stack memory for pinctrl_gpio_range pinctrl: zynq: Use devm_pinctrl_register() for pinctrl registration pinctrl: u300: Use devm_pinctrl_register() for pinctrl registration ... | |||
