2018-08-22module: allow symbol exports to be disabledArd Biesheuvel
To allow existing C code to be incorporated into the decompressor or the UEFI stub, introduce a CPP macro that turns all EXPORT_SYMBOL_xxx declarations into nops, and #define it in places where such exports are undesirable. Note that this gets rid of a rather dodgy redefine of linux/export.h's header guard.

2018-08-22drivers/block/zram/zram_drv.c: fix bug storing backing_devPeter Kalauskas
The call to strlcpy in backing_dev_store is incorrect. It should take the size of the destination buffer instead of the size of the source buffer. Additionally, ignore the newline character (\n) when reading the new file_name buffer. This makes it possible to set the backing_dev as follows: echo /dev/sdX > /sys/block/zram0/backing_dev The reason it worked before was the fact that strlcpy() copies 'len - 1' bytes, which is strlen(buf) - 1 in our case, so it accidentally didn't copy the trailing new line symbol. Which also means that "echo -n /dev/sdX" most likely was broken.

2018-08-22mm, oom: distinguish blockable mode for mmu notifiersMichal Hocko
There are several blockable mmu notifiers which might sleep in mmu_notifier_invalidate_range_start and that is a problem for the oom_reaper because it needs to guarantee a forward progress so it cannot depend on any sleepable locks. Currently we simply back off and mark an oom victim with blockable mmu notifiers as done after a short sleep. That can result in selecting a new oom victim prematurely because the previous one still hasn't torn its memory down yet. We can do much better though. Even if mmu notifiers use sleepable locks there is no reason to automatically assume those locks are held. Moreover majority of notifiers only care about a portion of the address space and there is absolutely zero reason to fail when we are unmapping an unrelated range. Many notifiers do really block and wait for HW which is harder to handle and we have to bail out though. This patch handles the low hanging fruit. __mmu_notifier_invalidate_range_start gets a blockable flag and callbacks are not allowed to sleep if the flag is set to false. This is achieved by using trylock instead of the sleepable lock for most callbacks and continue as long as we do not block down the call chain. I think we can improve that even further because there is a common pattern to do a range lookup first and then do something about that. The first part can be done without a sleeping lock in most cases AFAICS. The oom_reaper end then simply retries if there is at least one notifier which couldn't make any progress in !blockable mode. A retry loop is already implemented to wait for the mmap_sem and this is basically the same thing. The simplest way for driver developers to test this code path is to wrap userspace code which uses these notifiers into a memcg and set the hard limit to hit the oom. This can be done e.g. after the test faults in all the mmu notifier managed memory and set the hard limit to something really small. Then we are looking for a proper process tear down.

git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This contains some major improvements to the RISC-V port, including the necessary interrupt controller and timer support to actually make it to userspace. Support for three devices has been added: - the ISA-mandated timers on RISC-V systems. - the ISA-mandated first-level interrupt controller on RISC-V systems, which is handled as part of our core arch code because it's very small and tightly tied to the ISA. - SiFive's platform-level interrupt controller, which talks to the actual devices. In addition to these new devices, there are a handful of cleanups all over the RISC-V tree: - build fixes for various configurations: * A fix to the vDSO build's makefile so it respects CFLAGS. * The addition of __lshrti3, a libgcc derived function necessary for some 32-bit configurations. * !SMP && PERF_EVENTS - Cleanups to the arch code to remove the remnants of old versions of the drivers that were just properly submitted. * Some dead code from the timer driver, most of which wasn't ever even compiled. * Cleanups of some interrupt #defines, which are now local to the interrupt handling code. - Fixes to ptrace(), which while not being sufficient to fully make GDB work are at least sufficient to get simple GDB tasks to work. - Early printk support via RISC-V's architecturally mandated SBI console device. - A fix to our early debug trap handler to ensure it's always aligned. These patches have all been through a fairly extensive review process, but as this enables a whole pile of functionality (ie, userspace) I'm confident we'll need to submit a few more patches.

2018-08-18pcmcia: remove long deprecated pcmcia_request_exclusive_irq() functionLinus Torvalds
This function was created as a deprecated fallback case back in 2010 by commit eb14120f743d ("pcmcia: re-work pcmcia_request_irq()") for legacy cases. Actual in-kernel users haven't been around for a long while. The last in-kernel user was apparently removed four years ago by commit 5f5316fcd08e ("am2150: Update nmclan_cs.c to use update PCMCIA API"). Just remove it entirely.

2018-08-17kernel/dma: remove unsupported gfp_mask parameter from ↵Marek Szyprowski
dma_alloc_from_contiguous() The CMA memory allocator doesn't support standard gfp flags for memory allocation, so there is no point having it as a parameter for dma_alloc_from_contiguous() function. Replace it by a boolean no_warn argument, which covers all the underlaying cma_alloc() function supports. This will help to avoid giving false feeling that this function supports standard gfp flags and callers can pass __GFP_ZERO to get zeroed buffer, what has already been an issue: see commit dd65a941f6ba ("arm64: dma-mapping: clear buffers allocated with FORCE_CONTIGUOUS flag").

2018-08-17mm: provide a fallback for PAGE_KERNEL_RO for architecturesLuis R. Rodriguez
Some architectures do not define certain PAGE_KERNEL_* flags, this is either because: a) The way to implement some of these flags is *not yet ported*, or b) The architecture *has no way* to describe them Over time we have accumulated a few PAGE_KERNEL_* fallback workarounds for architectures in the kernel which do not define them using *relatively safe* equivalents. Move these scattered fallback hacks into asm-generic. We start off with PAGE_KERNEL_RO using PAGE_KERNEL as a fallback. This has been in place on the firmware loader for years.

2018-08-17mm/memory_hotplug.c: drop unnecessary checks from register_mem_sect_under_node()Oscar Salvador
Callers of register_mem_sect_under_node() are always passing a valid memory_block (not NULL), so we can safely drop the check for NULL. In the same way, register_mem_sect_under_node() is only called in case the node is online, so we can safely remove that check as well.

2018-08-17mm/memory_hotplug.c: make register_mem_sect_under_node() a callback of ↵Oscar Salvador
walk_memory_range() link_mem_sections() and walk_memory_range() share most of the code, so we can use convert link_mem_sections() into a dummy function that calls walk_memory_range() with a callback to register_mem_sect_under_node(). This patch converts register_mem_sect_under_node() in order to match a walk_memory_range's callback, getting rid of the check_nid argument and checking instead if the system is still boothing, since we only have to check for the nid if the system is in such state.

2018-08-17mm/memory_hotplug.c: call register_mem_sect_under_node()Oscar Salvador
When hotplugging memory, it is possible that two calls are being made to register_mem_sect_under_node(). One comes from __add_section()->hotplug_memory_register() and the other from add_memory_resource()->link_mem_sections() if we had to register a new node. In case we had to register a new node, hotplug_memory_register() will only handle/allocate the memory_block's since register_mem_sect_under_node() will return right away because the node it is not online yet. I think it is better if we leave hotplug_memory_register() to handle/allocate only memory_block's and make link_mem_sections() to call register_mem_sect_under_node(). So this patch removes the call to register_mem_sect_under_node() from hotplug_memory_register(), and moves the call to link_mem_sections() out of the condition, so it will always be called. In this way we only have one place where the memory sections are registered.

2018-08-17mm: convert return type of handle_mm_fault() caller to vm_fault_tSouptick Joarder
Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t") In this patch all the caller of handle_mm_fault() are changed to return vm_fault_t type.

2018-08-17firewire: use 64-bit time_t based interfacesArnd Bergmann
32-bit CLOCK_REALTIME timestamps overflow in year 2038, so all such interfaces are deprecated now. For the FW_CDEV_IOC_GET_CYCLE_TIMER2 ioctl, we already support 64-bit timestamps, but the implementation still uses timespec. This changes the code to use timespec64 instead with the appropriate accessor functions.

2018-08-17dax: remove VM_MIXEDMAP for fsdax and device daxDave Jiang
This patch is reworked from an earlier patch that Dan has posted: https://patchwork.kernel.org/patch/10131727/ VM_MIXEDMAP is used by dax to direct mm paths like vm_normal_page() that the memory page it is dealing with is not typical memory from the linear map. The get_user_pages_fast() path, since it does not resolve the vma, is already using {pte,pmd}_devmap() as a stand-in for VM_MIXEDMAP, so we use that as a VM_MIXEDMAP replacement in some locations. In the cases where there is no pte to consult we fallback to using vma_is_dax() to detect the VM_MIXEDMAP special case. Now that we have explicit driver pfn_t-flag opt-in/opt-out for get_user_pages() support for DAX we can stop setting VM_MIXEDMAP. This also means we no longer need to worry about safely manipulating vm_flags in a future where we support dynamically changing the dax mode of a file. DAX should also now be supported with madvise_behavior(), vma_merge(), and copy_page_range(). This patch has been tested against ndctl unit test. It has also been tested against xfstests commit: 625515d using fake pmem created by memmap and no additional issues have been observed.

Pull rdma updates from Jason Gunthorpe: "This has been a large cycle for RDMA, with several major patch series reworking parts of the core code. - Rework the so-called 'gid cache' and internal APIs to use a kref'd pointer to a struct instead of copying, push this upwards into the callers and add more stuff to the struct. The new design avoids some ugly races the old one suffered with. This is part of the namespace enablement work as the new struct is learning to be namespace aware. - Various uapi cleanups, moving more stuff to include/uapi and fixing some long standing bugs that have recently been discovered. - Driver updates for mlx5, mlx4 i40iw, rxe, cxgb4, hfi1, usnic, pvrdma, and hns - Provide max_send_sge and max_recv_sge attributes to better support HW where these values are asymmetric. - mlx5 user API 'devx' allows sending commands directly to the device FW, instead of trying to cram every wild and niche feature into the common API. Sort of like what GPU does. - Major write() and ioctl() API rework to cleanly support PCI device hot unplug and advance the ioctl conversion work - Sparse and compile warning cleanups - Add 'const' to the ib_poll_cq() signature, and permit a NULL 'bad_wr', which is the common use case - Various patches to avoid high order allocations across the stack - SRQ support for cxgb4, hns and qedr - Changes to IPoIB to better follow the netdev model for working with struct net_device liftime" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (312 commits) Revert "net/smc: Replace ib_query_gid with rdma_get_gid_attr" RDMA/hns: Fix usage of bitmap allocation functions return values IB/core: Change filter function return type from int to bool IB/core: Update GID entries for netdevice whose mac address changes IB/core: Add default GIDs of the bond master netdev IB/core: Consider adding default GIDs of bond device IB/core: Delete lower netdevice default GID entries in bonding scenario IB/core: Avoid confusing del_netdev_default_ips IB/core: Add comment for change upper netevent handling qedr: Add user space support for SRQ qedr: Add support for kernel mode SRQ's qedr: Add wrapping generic structure for qpidr and adjust idr routines.
