git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e, i40evf, e1000e, ixgbe and ixgbevf. Mitch adds support for the VF link state ndo which allows the PF driver to control the virtual link state of the VF devices. Added support for viewing and modifying RSS hash options and RSS hash look-up table programming through ethtool for i40evf. Fixed complaint about the use of min() where min_t() should be used in i40evf. Anjali adds support for ethtool -k option for NTUPLE control for i40e. Elizabeth cleans up and refactors i40e_open() to separate out the VSI code into its own i40e_vsi_open(). Jesse enables the hardware feature head write back to avoid updating the descriptor ring by marking each descriptor with a DD bit and instead writes a memory location with an update to where the driver should clean up to in i40e and i40evf. Reduces context descriptors for i40e/i40evf since we do not need context descriptors for every packet, only for TSO or timesync. Dan Carpenter fixes a potential array underflow in i40e_vc_process_vf_msg(). Dave fixes an e1000e hardware unit hang where the check for pending Tx work when link is lost was mistakenly moved to be done only when link is first detected to be lost. Fixed a problem with poor network performance on certain silicon in e1000e when configured for 100M HDX performance. Carolyn adds register defines needed for time sync functions and the code to call the updated defines. Jacob adds the ixgbe function for writing PCI config word and checks whether the adapter has been removed first. Mark adds the bit __IXGBEVF_REMOVING to indicate that the module is being removed because the __IXGBEVF_DOWN bit had been overloaded for this purpose, but leads to trouble. ixgbevf_down function can now prevent multiple executions by doing test_and_set_bit on __IXGBEVF_DOWN. v2: - dropped patch Mitch's patch "i40evf: Support RSS option in ethtool" based on feedback from Ben Hutchings so that Mitch can re-work the patch solution v3: - removed unnecessary parenthesis in patch 1 based on feedback from David Miller - changed a macro to get the next queue to a function in patch 2 based on feedback from David Miller - added blank lines after variable declaration and code in two functions in patch 6 based on feedback from David Miller ==================== Signed-off-by: David S.

2014-03-19fsl/pci: The new pci suspend/resume implementationWang Dongsheng
If we do nothing in suspend/resume, some platform PCIe ip-block can't guarantee the link back to L0 state from sleep, then, when we read the EP device will hang. Only we send pme turnoff message in pci controller suspend, and send pme exit message in resume, the link state will be normal. When we send pme turnoff message in pci controller suspend, the links will into l2/l3 ready, then, host cannot communicate with ep device, but pci-driver will call back EP device to save them state. So we need to change platform_driver->suspend/resume to syscore->suspend/resume. So the new suspend/resume implementation, send pme turnoff message in suspend, and send pme exit message in resume. And add a PME handler, to response PME & message interrupt. Change platform_driver->suspend/resume to syscore->suspend/resume. pci-driver will call back EP device, to save EP state in pci_pm_suspend_noirq, so we need to keep the link, until pci_pm_suspend_noirq finish.

Change to use the new ->stop_cpu() callback to do clean up during CPU hotplug.

2014-03-20cpufreq: Add stop CPU callback to cpufreq_driver interfaceDirk Brandewie
This callback allows the driver to do clean up before the CPU is completely down and its state cannot be modified. This is used by the intel_pstate driver to reduce the requested P state prior to the core going away. This is required because the requested P state of the offline core is used to select the package P state. This effectively sets the floor package P state to the requested P state on the offline core.

2014-03-20staging: octeon-usb: prevent memory corruptionAaro Koskinen
octeon-hcd will crash the kernel when SLOB is used. This usually happens after the 18-byte control transfer when a device descriptor is read. The DMA engine is always transfering full 32-bit words and if the transfer is shorter, some random garbage appears after the buffer. The problem is not visible with SLUB since it rounds up the allocations to word boundary, and the extra bytes will go undetected. Fix by providing quirk functions for DMA map/unmap that allocate a bigger temporary buffer when necessary. Tested by booting EdgeRouter Lite to USB stick root file system with SLAB, SLOB and SLUB kernels.

2014-03-19powerpc/booke64: Critical and machine check exception supportScott Wood
Add special state saving for critical and machine check exceptions. Most of this code could be used to handle debug exceptions taken from kernel space, but actually doing so is outside the scope of this patch. The various critical and machine check exceptions now point to their real handlers, rather than hanging the kernel. Signed-off-by: Scott Wood <scottwood@freescale.com>
2014-03-19powerpc/booke64: Add crit/mc/debug support to EXCEPTION_COMMONScott Wood
Use the proper scratch SPRG and PACA region. Introduce level-specific macros to simplify usage and avoid needing to do a bunch of token pasting throughout EXCEPTION_COMMON(). Now that EXCEPTION_COMMON_DBG() is properly using the debug scratch register, there's no more need for the caller to move the value to the GEN scratch first. Signed-off-by: Scott Wood <scottwood@freescale.com>
2014-03-19powerpc/booke64: Remove ints from EXCEPTION_COMMONScott Wood
The ints parameter was used to optionally insert RECONCILE_IRQ_STATE into EXCEPTION_COMMON. However, since it came at the end of EXCEPTION_COMMON, there was no real benefit for it to be there as opposed to being called separately by the caller of EXCEPTION_COMMON. The ints parameter was causing some hassle when trying to add an extra macro layer. Besides avoiding that, moving "ints" to the caller makes the code simpler by: - avoiding the asymmetry where INTS_RESTORE_HARD is called separately by the individual exception, but INTS_DISABLE was not - removing the no-op INTS_KEEP - not having an unnecessary macro parameter It also turned out to be necessary to delay the INTS_DISABLE in the case of special level exceptions until after we saved the old value of PACAIRQHAPPENED.

2014-03-19powerpc/booke64: Use SPRG_TLB_EXFRAME on bolted handlersScott Wood
While bolted handlers (including e6500) do not need to deal with a TLB miss recursively causing another TLB miss, nested TLB misses can still happen with crit/mc/debug exceptions -- so we still need to honor SPRG_TLB_EXFRAME. We don't need to spend time modifying it in the TLB miss fastpath, though -- the special level exception will handle that.

2014-03-19powerpc/booke64: Use SPRG7 for VDSOScott Wood
Previously SPRG3 was marked for use by both VDSO and critical interrupts (though critical interrupts were not fully implemented). In commit 8b64a9dfb091f1eca8b7e58da82f1e7d1d5fe0ad ("powerpc/booke64: Use SPRG0/3 scratch for bolted TLB miss & crit int"), Mihai Caraman made an attempt to resolve this conflict by restoring the VDSO value early in the critical interrupt, but this has some issues: - It's incompatible with EXCEPTION_COMMON which restores r13 from the by-then-overwritten scratch (this cost me some debugging time). - It forces critical exceptions to be a special case handled differently from even machine check and debug level exceptions. - It didn't occur to me that it was possible to make this work at all (by doing a final "ld r13, PACA_EXCRIT+EX_R13(r13)") until after I made (most of) this patch. :-) It might be worth investigating using a load rather than SPRG on return from all exceptions (except TLB misses where the scratch never leaves the SPRG) -- it could save a few cycles. Until then, let's stick with SPRG for all exceptions. Since we cannot use SPRG4-7 for scratch without corrupting the state of a KVM guest, move VDSO to SPRG7 on book3e. Since neither SPRG4-7 nor critical interrupts exist on book3s, SPRG3 is still used for VDSO there.

2014-03-19powerpc/e6500: Make TLB lock recursiveScott Wood
Once special level interrupts are supported, we may take nested TLB misses -- so allow the same thread to acquire the lock recursively. The lock will not be effective against the nested TLB miss handler trying to write the same entry as the interrupted TLB miss handler, but that's also a problem on non-threaded CPUs that lack TLB write conditional. This will be addressed in the patch that enables crit/mc support by invalidating the TLB on return from level exceptions. Signed-off-by: Scott Wood <scottwood@freescale.com>

2014-03-19i40evf: use min_tMitch Williams
Checkpatch complained in an earlier patch about using min(), but that change would have been completely unrelated to the point of that patch. So fix it here.

2014-03-19i40evf: correctly program RSS HLUT tableMitch Williams
The HLUT programming loop in in i40evf_configure_rss was a) overly- complicated, and b) just plain broken. Most of the entries ended up being not written at all, so most of the flows ended up at queue zero. Refactor the HLUT programming loop to simply walk through the registers and write four values to each one, incrementing through the number of available queues.
