2017-02-21Merge tag 'extable-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull exception table module split from Paul Gortmaker: "Final extable.h related changes. This completes the separation of exception table content from the module.h header file. This is achieved with the final commit that removes the one line back compatible change that sourced extable.h into the module.h file. The commits are unchanged since January, with the exception of a couple Acks that came in for the last two commits a bit later. The changes have been in linux-next for quite some time[1] and have got widespread arch coverage via toolchains I have and also from additional ones the kbuild bot has. Maintaners of the various arch were Cc'd during the postings to lkml[2] and informed that the intention was to take the remaining arch specific changes and lump them together with the final two non-arch specific changes and submit for this merge window. The ia64 diffstat stands out and probably warrants a mention.

2017-02-21rtc: armada38x: Add support for Armada 7K/8KGregory CLEMENT
The Armada 7K/8K use the same RTC IP than the Armada 38x. However the SOC integration differs in 2 points: - MBUS bridge timing initialization - IRQ configuration at SoC level Moreover the Armada 7K/8K have an issue preventing to get the interrupt from alarm 1. This commit allows to use alarm 2 for these A7K/8K but to still use alarm 1 for the Armada 38x.

2017-02-21drm/amdgpu: refuse to reserve io mem for split VRAM buffersNicolai Hähnle
When the fast blit path fails while attempting to move a buffer from RAM to VRAM, we fall back to a CPU-based memcpy that cannot handle split VRAM buffers. Instead of crashing, simply fail the buffer move. Ideally, we would teach TTM about split buffers so that the fallback still works in this case, but that is quite involved. So for now, apply the simplest possible fix.

2017-02-21drm/ttm: fix use-after-free races in vm fault handlingNicolai Hähnle
The vm fault handler relies on the fact that the VMA owns a reference to the BO. However, once mmap_sem is released, other tasks are free to destroy the VMA, which can lead to the BO being freed. Fix two code paths where that can happen, both related to vm fault retries. Found via a lock debugging warning which flagged &bo->wu_mutex as locked while being destroyed.

Since there is little gain by runtime PM on BYT/CHT, so far, this commit removes the pm_runtime_enable() call as default.

This leads to memory corruption in the call to scsi_req_init() in bsg_map_hdr(), since it will memset past the end of the allocated request.

2017-02-21PCI: dwc: all: Use platform_set_drvdata() to save private dataKishon Vijay Abraham I
Add platform_set_drvdata() in all designware-based drivers to store the private data structure of the driver so that dev_set_drvdata() can be used to get back private data structure in add_pcie_port/host_init. This is in preparation for splitting struct pcie_port into core and host only structures. After the split pcie_port will not be part of the driver's private data structure and *container_of* used now to get the private data pointer cannot be used.

2017-02-21PCI: dwc: designware: Move register defines to designware header fileKishon Vijay Abraham I
No functional change. Move the register defines and other macros from pcie-designware.c to pcie-designware.h. This is in preparation to split the pcie-designware.c file into designware core file and host-specific file. While at that also fix a checkpatch warning.

No functional change. PHY APIs like phy_init()/phy_power_on() are invoked from multiple places. Group all the PHY APIs in dra7xx_pcie_enable_phy() and dra7xx_pcie_disable_phy() and use these functions for enabling or disabling the PHY.

2017-02-21PCI: dra7xx: Enable MSI and legacy interrupts simultaneouslyKishon Vijay Abraham I
pci-dra7xx driver had a bug in that if CONFIG_PCI_MSI config is enabled, it doesn't support legacy interrupt. Fix it here so that both MSI and legacy interrupts can be enabled simultaneously and the interrupt mechanism supported by the endpoint device will be used.
