All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller <davem@davemloft.net>

2016-11-18config: Adding the new config parameter CONFIG_PROVE_LOCKING_SMALL for sparcBabu Moger1-0/+1
This new config parameter limits the space used for "Lock debugging: prove locking correctness" by about 4MB. The current sparc systems have the limitation of 32MB size for kernel size including .text, .data and .bss sections. With PROVE_LOCKING feature, the kernel size could grow beyond this limit and causing system boot-up issues. With this option, kernel limits the size of the entries of lock_chains, stack_trace etc., so that kernel fits in required size limit. This is not visible to user and only used for sparc.

2016-11-18sparc64: Add ATU (new IOMMU) supportTushar Dave6-0/+529
ATU (Address Translation Unit) is a new IOMMU in SPARC supported with Hypervisor IOMMU v2 APIs. Current SPARC IOMMU supports only 32bit address ranges and one TSB per PCIe root complex that has a 2GB per root complex DVMA space limit. The limit has become a scalability bottleneck nowadays that a typical 10G/40G NIC can consume 300MB-500MB DVMA space per instance. When DVMA resource is exhausted, devices will not be usable since the driver can't allocate DVMA. ATU removes bottleneck by allowing guest os to create IOTSB of size 32G (or more) with 64bit address ranges available in ATU HW. 32G is more than enough DVMA space to be shared by all PCIe devices under root complex contrast to 2G space provided by legacy IOMMU. ATU allows PCIe devices to use 64bit DMA addressing. Devices which choose to use 32bit DMA mask will continue to work with the existing legacy IOMMU.

2016-11-18KVM: arm64: Fix the issues when guest PMCCFILTR is configuredWei Huang2-10/+10
KVM calls kvm_pmu_set_counter_event_type() when PMCCFILTR is configured. But this function can't deals with PMCCFILTR correctly because the evtCount bits of PMCCFILTR, which is reserved 0, conflits with the SW_INCR event type of other PMXEVTYPER<n> registers. To fix it, when eventsel == 0, this function shouldn't return immediately; instead it needs to check further if select_idx is ARMV8_PMU_CYCLE_IDX. Another issue is that KVM shouldn't copy the eventsel bits of PMCCFILTER blindly to attr.config. Instead it ought to convert the request to the "cpu cycle" event type (i.e. 0x11). To support this patch and to prevent duplicated definitions, a limited set of ARMv8 perf event types were relocated from perf_event.c to asm/perf_event.h.

Commit 7619751f8c90 ("ARM: 8595/2: apply more __ro_after_init") caused a regression with XIP kernels by moving the __ro_after_init data into the read-only section. With XIP kernels, the read-only section is located in read-only memory from the very beginning. Work around this by moving the __ro_after_init data back into the .data section, which will be in RAM, and hence will be writable. It should be noted that in doing so, this remains writable after init.

2016-11-15ARM: 8628/1: dma-mapping: preallocate DMA-debug hash tables in core_initcallMarek Szyprowski1-1/+1
fs_initcall is definitely too late to initialize DMA-debug hash tables, because some drivers might get probed and use DMA mapping framework already in core_initcall. Late initialization of DMA-debug results in false warning about accessing memory, that was not allocated, like this one: ------------[ cut here ]------------ WARNING: CPU: 5 PID: 1 at lib/dma-debug.c:1104 check_unmap+0xa1c/0xe50 exynos-sysmmu 10a60000.sysmmu: DMA-API: device driver tries to free DMA memory it has not allocated [device address=0x000000006ebd0000] [size=16384 bytes] Modules linked in: CPU: 5 PID: 1 Comm: swapper/0 Not tainted 4.9.0-rc5-00028-g39dde3d-dirty #44 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [<c0119dd4>] (unwind_backtrace) from [<c01122bc>] (show_stack+0x20/0x24) [<c01122bc>] (show_stack) from [<c062714c>] (dump_stack+0x84/0xa0) [<c062714c>] (dump_stack) from [<c0132560>] (__warn+0x14c/0x180) [<c0132560>] (__warn) from [<c01325dc>] (warn_slowpath_fmt+0x48/0x50) [<c01325dc>] (warn_slowpath_fmt) from [<c06814f8>] (check_unmap+0xa1c/0xe50) [<c06814f8>] (check_unmap) from [<c06819c4>] (debug_dma_unmap_page+0x98/0xc8) [<c06819c4>] (debug_dma_unmap_page) from [<c076c3e8>] (exynos_iommu_domain_free+0x158/0x380) [<c076c3e8>] (exynos_iommu_domain_free) from [<c0764a30>] (iommu_domain_free+0x34/0x60) [<c0764a30>] (iommu_domain_free) from [<c011f168>] (release_iommu_mapping+0x30/0xb8) [<c011f168>] (release_iommu_mapping) from [<c011f23c>] (arm_iommu_release_mapping+0x4c/0x50) [<c011f23c>] (arm_iommu_release_mapping) from [<c0b061ac>] (s5p_mfc_probe+0x640/0x80c) [<c0b061ac>] (s5p_mfc_probe) from [<c07e6750>] (platform_drv_probe+0x70/0x148) [<c07e6750>] (platform_drv_probe) from [<c07e25c0>] (driver_probe_device+0x12c/0x6b0) [<c07e25c0>] (driver_probe_device) from [<c07e2c6c>] (__driver_attach+0x128/0x17c) [<c07e2c6c>] (__driver_attach) from [<c07df74c>] (bus_for_each_dev+0x88/0xc8) [<c07df74c>] (bus_for_each_dev) from [<c07e1b6c>] (driver_attach+0x34/0x58) [<c07e1b6c>] (driver_attach) from [<c07e1350>] (bus_add_driver+0x18c/0x32c) [<c07e1350>] (bus_add_driver) from [<c07e4198>] (driver_register+0x98/0x148) [<c07e4198>] (driver_register) from [<c07e5cb0>] (__platform_driver_register+0x58/0x74) [<c07e5cb0>] (__platform_driver_register) from [<c174cb30>] (s5p_mfc_driver_init+0x1c/0x20) [<c174cb30>] (s5p_mfc_driver_init) from [<c0102690>] (do_one_initcall+0x64/0x258) [<c0102690>] (do_one_initcall) from [<c17014c0>] (kernel_init_freeable+0x3d0/0x4d0) [<c17014c0>] (kernel_init_freeable) from [<c116eeb4>] (kernel_init+0x18/0x134) [<c116eeb4>] (kernel_init) from [<c010bbd8>] (ret_from_fork+0x14/0x3c) ---[ end trace dc54c54bd3581296 ]--- This patch moves initialization of DMA-debug to core_initcall. This is safe from the initialization perspective. dma_debug_do_init() internally calls debugfs functions and debugfs also gets initialised at core_initcall(), and that is earlier than arch code in the link order, so it will get initialized just before the DMA-debug.

2016-11-15ARM: fix backtraceRussell King2-34/+23
Recent kernels have changed their behaviour to be more inconsistent when handling printk continuations. With todays kernels, the output looks sane on the console, but dmesg splits individual printk()s which do not have the KERN_CONT prefix into separate lines. Since the assembly code is not trivial to add the KERN_CONT, and we ideally want to avoid using KERN_CONT (as multiple printk()s can race between different threads), convert the assembly dumping the register values to C code, and have the C code build the output a line at a time before dumping to the console. This avoids the KERN_CONT issue, and also avoids situations where the output is intermixed with other console activity. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2016-11-15powerpc/64: Fix setting of AIL in hypervisor modeBenjamin Herrenschmidt1-6/+14
Commit d3cbff1b5 "powerpc: Put exception configuration in a common place" broke the setting of the AIL bit (which enables taking exceptions with the MMU still on) on all processors, moving it incorrectly to a function called only on the boot CPU. This was correct for the guest case but not when running in hypervisor mode. This fixes it by partially reverting that commit, putting the setting back in cpu_ready_for_interrupts() Fixes: d3cbff1b5a90 ("powerpc: Put exception configuration in a common place") Cc: stable@vger.kernel.org # v4.8+ Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

2016-11-14tile: handle __ro_after_init like parisc doesChris Metcalf1-0/+3
The tile architecture already marks RO_DATA as read-only in the kernel, so grouping RO_AFTER_INIT_DATA with RO_DATA, as is done by default, means the kernel faults in init when it tries to write to RO_AFTER_INIT_DATA. For now, just arrange that __ro_after_init is handled like __write_once, i.e. __read_mostly. Reviewed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Chris Metcalf <cmetcalf@mellanox.com>
2016-11-14ARM: dts: omap5: board-common: fix wrong SMPS6 (VDD-DDR3) voltageH. Nikolaus Schaller1-2/+2
DDR3L is usually specified as JEDEC standard 1.35V(1.28V~1.45V) & 1.5V(1.425V~1.575V) Therefore setting smps6 regulator to 1.2V is definitively below minimum. It appears that real world chips are more forgiving than data sheets indicate, but let's set the regulator right. Note: a board that uses other voltages (DDR with 1.5V) can overwrite by referencing &smps6_reg. Signed-off-by: H. Nikolaus Schaller <hns@goldelico.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

A compile warning is introduced by a commit to fix the find_node(). This patch fix the compile warning by moving find_node() into __init section. Because find_node() is only used by memblock_nid_range() which is only used by a __init add_node_ranges(). find_node() and memblock_nid_range() should also be inside __init section.
