2014-10-06mmc: sdhci-acpi: Fix Braswell eMMC timeout clock frequencyAdrian Hunter
Braswell eMMC host controller specifies an incorrect timeout clock frequncy in the capabilities registers. The correct value is 1 MHz. A similar fix was done for sdhci-pci, however in the sdhci-acpi case the HID/UID is not unique so the capabilities register values are matched also.

2014-10-06workqueue: Use cond_resched_rcu_qs macroJoe Lawrence
Tidy up and use cond_resched_rcu_qs when calling cond_resched and reporting potential quiescent state to RCU. Splitting this change in this way allows easy backporting to -stable for kernel versions not having cond_resched_rcu_qs().

2014-10-06workqueue: Add quiescent state between work itemsJoe Lawrence
Similar to the stop_machine deadlock scenario on !PREEMPT kernels addressed in b22ce2785d97 "workqueue: cond_resched() after processing each work item", kworker threads requeueing back-to-back with zero jiffy delay can stall RCU. The cond_resched call introduced in that fix will yield only iff there are other higher priority tasks to run, so force a quiescent RCU state between work items.

2014-10-06x86/xen: Set EFER.NX and EFER.SCE in PVH guestsMukesh Rathor
This fixes two bugs in PVH guests: - Not setting EFER.NX means the NX bit in page table entries is ignored on Intel processors and causes reserved bit page faults on AMD processors. - After the Xen commit 7645640d6ff1 ("x86/PVH: don't set EFER_SCE for pvh guest") PVH guests are required to set EFER.SCE to enable the SYSCALL instruction. Secondary VCPUs are started with pagetables with the NX bit set so EFER.NX must be set before using any stack or data segment. xen_pvh_cpu_early_init() is the new secondary VCPU entry point that sets EFER before jumping to cpu_bringup_and_idle().

It also introduce setting/getting tx copybreak, to enable controlling inline threshold dynamically. TX flow optimizations was authored and posted to the mailing list by Eric Dumazet [1] as a single patch. I splitted this patch to smaller patches, Reviewed it and tested. Changed from original patch: - s/iowrite32be/iowrite32/, since ring->doorbell_qpn is stored as be32 The tx copybreak patch was also suggested by Eric Dumazet, and was edited and reviewed by me. User space patch will be sent after kernel code is ready. I am sending this patchset now since the merge window is near and don't want to miss it. More work need to do: - Disable BF when xmit_more is in use - Make TSO use xmit_more too. Maybe by splitting small TSO packets in the driver itself, to avoid extra cpu/memory costs of GSO before the driver - Fix mlx4_en_xmit buggy handling of queue full in the middle of a burst partially posted to send queue using xmit_more Eric, I edited the patches to have you as the Author and the first signed-off-by.

2014-10-06openvswitch: Wrap struct ovs_key_ipv4_tunnel in a new structure.Jesse Gross
Currently, the flow information that is matched for tunnels and the tunnel data passed around with packets is the same. However, as additional information is added this is not necessarily desirable, as in the case of pointers. This adds a new structure for tunnel metadata which currently contains only the existing struct.
