2012-03-08mlx4_core: fix bug in modify_cq wrapper for resize flow.Jack Morgenstein1-2/+1
The actual FW command is called in procedure "handle_resize". Code incorrectly invoked the FW command again (in good flow), in the modify_cq wrapper function. Fix by skipping second FW invocation unconditionally for resize. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>

Commit 239c562c94d (ehea: Add 64bit statistics) added a regression, since we no longer report multicast & rx_errors fields, taken from port->stats structure.

Pull networking fixes from David Miller: 1) TCP can chop up SACK'd SKBs below below the unacked send sequence and that breaks lots of stuff. Fix from Neal Cardwell. 2) There is code in ipv6 to properly join and leave the all-routers multicast code when the forwarding setting is changed, but once forwarding is turned on, we don't do the join for newly registered devices. Fix from Li Wei. 3) Netfilter's NAT module autoload in ctnetlink drops a spinlock around a sleeping call, problem is this code path doesn't actually hold that lock. Fix from Pablo Neira Ayuso. 4) TG3 uses the wrong interfaces to hook into the new byte queue limit support. It uses the device level interfaces, which is fine for single queue devices, but on more recent chips this driver supports multiqueue so we have to use the multiqueue BQL APIs. Fix from Tom Herbert. 5) r8169 resume fix from Francois Romieu. 6) Add some cxgb4 device IDs, from Vipul Pandya. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: IPv6: Fix not join all-router mcast group when forwarding set. caif-hsi: Set default MTU to 4096 cxgb4vf: Add support for Chelsio's T480-CR and T440-LP-CR adapters cxgb4: Add support for Chelsio's T480-CR and T440-LP-CR adapters mlx4_core: remove buggy sched_queue masking netfilter: nf_conntrack: fix early_drop with reliable event delivery bridge: netfilter: don't call iptables on vlan packets if sysctl is off netfilter: bridge: fix wrong pointer dereference netfilter: ctnetlink: remove incorrect spin_[un]lock_bh on NAT module autoload netfilter: ebtables: fix wrong name length while copying to user-space r8169: runtime resume before shutdown. tcp: fix tcp_shift_skb_data() to not shift SACKed data below snd_una tg3: Fix to use multi queue BQL interfaces

2012-03-06r8169: runtime resume before shutdown.françois romieu1-0/+5
With runtime PM, if the ethernet cable is disconnected, the device is transitioned to D3 state to conserve energy. If the system is shutdown in this state, any register accesses in rtl_shutdown are dropped on the floor. As the device was programmed by .runtime_suspend() to wake on link changes, it is thus brought back up as soon as the link recovers. Resuming every suspended device through the driver core would slow things down and it is not clear how many devices really need it now. Original report and D0 transition patch by Sameer Nanda. Patch has been changed to comply with advices by Rafael J. Wysocki and the PM folks.

Production GMA3600/3650 hardware turns out to be subtly different to the development platforms. This combined with a minor driver bug is causing the kernel to hang on these platforms. This patch does the following - turn down a couple of messages that were meant to be debug and are causing much confusion - ensure the hotplug interrupt is disabled on Cedartrail systems. - fix a bug where gtt roll mode called psbfb_sync, which tries to sync the 2D engine. On other devices it is harmless as the 2D engine is present but not in use when in gtt roll mode, on Cedartrail it causes a hang Without these changes 3.3-rc hangs on boot on Cedartrail based systems.

From Dan Carpenter. 6) We must check the return value of nlmsg_parse() before trying to use the results. From Eric Dumazet. 7) Bridging code fails to check return value of ipv6_dev_get_saddr() thus potentially leaving uninitialized garbage in the outgoing ipv6 header. From Ulrich Weber. 8) Due to rounding and a reversed operation on jiffies, bridge message ages can go backwards instead of forwards, thus breaking STP. Fixes from Joakim Tjernlund. 9) r8169 modifies Config* registers without properly holding the Config9346 lock, resulting in corrupted IP fragments on some chips.

Allow array field values out of range as per HID 1.11 specification, section 6.2.25: Rather than returning a single bit for each button in the group, an array returns an index in each field that corresponds to the pressed button (like keyboard scan codes). An out-of range value in and array field is considered no controls asserted. Apparently, "and" above is a typo and should be "an". This fixes at least Waltop tablet pen clicks - otherwise BTN_TOUCH is never released. The relevant part of Waltop tablet report descriptors is this: 0x09, 0x42, /* Usage (Tip Switch), */ 0x09, 0x44, /* Usage (Barrel Switch), */ 0x09, 0x46, /* Usage (Tablet Pick), */ 0x15, 0x01, /* Logical Minimum (1), */ 0x25, 0x03, /* Logical Maximum (3), */ 0x75, 0x04, /* Report Size (4), */ 0x95, 0x01, /* Report Count (1), */ 0x80, /* Input, */ This is a regression fix for commit b4b583d ("HID: be more strict when ignoring out-of-range fields").

2012-03-04mmc: core: Fixup suspend/resume issues for UHS-I cardsUlf Hansson4-5/+17
Even if cards supports 1.8V I/O voltage those should anyway be initialized at 3.3V I/O according to (e)MMC, SD and SDIO specs. Some eMMC and embedded SDIO devices are able to be initialized at 1.8V as well, but it is better to be safe. Do note that initialization in this context means that the card has been completely powered off, otherwise the card will remain at the last I/O voltage level that were negotitiated. Due to the above being taken care of the suspend/resume issues for UHS-I SD-cards has been fixed.

2012-03-04mmc: sdhci-esdhc-imx: fix for mmc cards on i.MX5Sascha Hauer1-2/+3
On i.MX53 we have to write a special SDHCI_CMD_ABORTCMD to the SDHCI_TRANSFER_MODE register during a MMC_STOP_TRANSMISSION command. This works for SD cards. However, with MMC cards the MMC_SET_BLOCK_COUNT command is used instead, but this needs the same handling. Fix MMC cards by testing for the MMC_SET_BLOCK_COUNT command aswell. Tested on a custom i.MX53 board with a Transcend MMC+ card and eMMC. The kernel started used MMC_SET_BLOCK_COUNT in 3.0, so this is a regression for these boards introduced in 3.0; it should go to 3.0/3.1/3.2-stable.

2012-03-04mmc: core: fix regression: set default clock gating delay to 0Guennadi Liakhovetski1-2/+2
A recent commit "mmc: core: Use delayed work in clock gating framework" (597dd9d79cfbbb1) introduced a default 200ms delay before clock gating actually takes place. This means that every time an MMC interface becomes idle it first stays on for 200ms before gating its clock. This leads to increased power consumption and is therefore a clear regression. This patch restores the original behaviour by setting the default delay to 0. Users prioritising throughput over power efficiency can still modify the delay via sysfs.

2012-03-02Revert "powerpc/usb: fix issue of CPU halt when missing USB PHY clock"Greg Kroah-Hartman2-10/+2
This reverts commit 529febeee680dc22416fca033151a5e8bc620447. To quote Dirk: This commit introduces a check for the USB PHY clock. Problem is that CTRL_PHY_CLK_VALID bit seems not to be present on all Freescale ehci implementations, at least P1022 does not have it. So this check always fails and the driver never gets loaded. So we need to revert this patch.

2012-03-02hwmon: (f75375s) Catch some attempts to write to r/o registersNikolaus Schulz1-0/+27
It makes no sense to attempt to manually configure the fan in auto mode, or set the duty cycle directly in closed loop mode. The corresponding registers are then read-only. If the user tries it nonetheless, error out with EINVAL instead of silently doing nothing.

2012-03-02hwmon: (f75375s) Properly map the F75387 automatic modes to pwm_enableNikolaus Schulz1-8/+34
The F75387 supports automatic fan control using either PWM duty cycle or RPM speed values. Make the driver detect the latter mode, and expose the different modes in sysfs as per pwm_enable, so that the user can switch between them. The interpretation of the pwm_enable attribute for the F75387 is adjusted to be a superset of those values used for similar Fintek chips which do not support automatic duty mode, with 2 mapping to automatic speed mode, and moving automatic duty mode to the new value 4. Toggling the duty mode via pwm_enable is currently denied for the F75387, as the chip then simply reinterprets the fan configuration register values according to the new mode, switching between RPM and PWM units, which makes this a dangerous operation. This patch introduces a new pwm mode into the driver. This is necessary because the new mode (automatic pwm mode, 4) may already be enabled by the BIOS, and the driver should not break existing functionality. This was seen on at least one board.
