2021-05-06can: mcp251x: fix resume from sleep before interface was brought upFrieder Schrempf
Since 8ce8c0abcba3 the driver queues work via priv->restart_work when resuming after suspend, even when the interface was not previously enabled. This causes a null dereference error as the workqueue is only allocated and initialized in mcp251x_open(). To fix this we move the workqueue init to mcp251x_can_probe() as there is no reason to do it later and repeat it whenever mcp251x_open() is called.

2021-05-05drm/amdgpu: Use device specific BO size & stride check.Bas Nieuwenhuizen
The builtin size check isn't really the right thing for AMD modifiers due to a couple of reasons: 1) In the format structs we don't do set any of the tilesize / blocks etc. to avoid having format arrays per modifier/GPU 2) The pitch on the main plane is pixel_pitch * bytes_per_pixel even for tiled ... 3) The pitch for the DCC planes is really the pixel pitch of the main surface that would be covered by it ... Note that we only handle GFX9+ case but we do this after converting the implicit modifier to an explicit modifier, so on GFX9+ all framebuffers should be checked here. There is a TODO about DCC alignment, but it isn't worse than before and I'd need to dig a bunch into the specifics. Getting this out in a reasonable timeframe to make sure it gets the appropriate testing seemed more important. Finally as I've found that debugging addfb2 failures is a pita I was generous adding explicit error messages to every failure case.

2021-05-05mm,memory_hotplug: allocate memmap from the added memory rangeOscar Salvador
Physical memory hotadd has to allocate a memmap (struct page array) for the newly added memory section. Currently, alloc_pages_node() is used for those allocations. This has some disadvantages: a) an existing memory is consumed for that purpose (eg: ~2MB per 128MB memory section on x86_64) This can even lead to extreme cases where system goes OOM because the physically hotplugged memory depletes the available memory before it is onlined. b) if the whole node is movable then we have off-node struct pages which has performance drawbacks. c) It might be there are no PMD_ALIGNED chunks so memmap array gets populated with base pages. This can be improved when CONFIG_SPARSEMEM_VMEMMAP is enabled. Vmemap page tables can map arbitrary memory. That means that we can reserve a part of the physically hotadded memory to back vmemmap page tables. This implementation uses the beginning of the hotplugged memory for that purpose. There are some non-obviously things to consider though. Vmemmap pages are allocated/freed during the memory hotplug events (add_memory_resource(), try_remove_memory()) when the memory is added/removed. This means that the reserved physical range is not online although it is used. The most obvious side effect is that pfn_to_online_page() returns NULL for those pfns. The current design expects that this should be OK as the hotplugged memory is considered a garbage until it is onlined. For example hibernation wouldn't save the content of those vmmemmaps into the image so it wouldn't be restored on resume but this should be OK as there no real content to recover anyway while metadata is reachable from other data structures (e.g. vmemmap page tables). The reserved space is therefore (de)initialized during the {on,off}line events (mhp_{de}init_memmap_on_memory). That is done by extracting page allocator independent initialization from the regular onlining path. The primary reason to handle the reserved space outside of {on,off}line_pages is to make each initialization specific to the purpose rather than special case them in a single function. As per above, the functions that are introduced are: - mhp_init_memmap_on_memory: Initializes vmemmap pages by calling move_pfn_range_to_zone(), calls kasan_add_zero_shadow(), and onlines as many sections as vmemmap pages fully span. - mhp_deinit_memmap_on_memory: Offlines as many sections as vmemmap pages fully span, removes the range from zhe zone by remove_pfn_range_from_zone(), and calls kasan_remove_zero_shadow() for the range. The new function memory_block_online() calls mhp_init_memmap_on_memory() before doing the actual online_pages(). Should online_pages() fail, we clean up by calling mhp_deinit_memmap_on_memory(). Adjusting of present_pages is done at the end once we know that online_pages() succedeed. On offline, memory_block_offline() needs to unaccount vmemmap pages from present_pages() before calling offline_pages(). This is necessary because offline_pages() tears down some structures based on the fact whether the node or the zone become empty. If offline_pages() fails, we account back vmemmap pages. If it succeeds, we call mhp_deinit_memmap_on_memory(). Hot-remove: We need to be careful when removing memory, as adding and removing memory needs to be done with the same granularity. To check that this assumption is not violated, we check the memory range we want to remove and if a) any memory block has vmemmap pages and b) the range spans more than a single memory block, we scream out loud and refuse to proceed. If all is good and the range was using memmap on memory (aka vmemmap pages), we construct an altmap structure so free_hugepage_table does the right thing and calls vmem_altmap_free instead of free_pagetable.

2021-05-05drivers/base/memory: introduce memory_block_{online,offline}Oscar Salvador
Patch series "Allocate memmap from hotadded memory (per device)", v10. The primary goal of this patchset is to reduce memory overhead of the hot-added memory (at least for SPARSEMEM_VMEMMAP memory model). The current way we use to populate memmap (struct page array) has two main drawbacks: a) it consumes an additional memory until the hotadded memory itself is onlined and b) memmap might end up on a different numa node which is especially true for movable_node configuration. c) due to fragmentation we might end up populating memmap with base pages One way to mitigate all these issues is to simply allocate memmap array (which is the largest memory footprint of the physical memory hotplug) from the hot-added memory itself. SPARSEMEM_VMEMMAP memory model allows us to map any pfn range so the memory doesn't need to be online to be usable for the array. See patch 4 for more details. This feature is only usable when CONFIG_SPARSEMEM_VMEMMAP is set. [Overall design]: Implementation wise we reuse vmem_altmap infrastructure to override the default allocator used by vmemap_populate. memory_block structure gains a new field called nr_vmemmap_pages, which accounts for the number of vmemmap pages used by that memory_block. E.g: On x86_64, that is 512 vmemmap pages on small memory bloks and 4096 on large memory blocks (1GB) We also introduce new two functions: memory_block_{online,offline}. These functions take care of initializing/unitializing vmemmap pages prior to calling {online,offline}_pages, so the latter functions can remain totally untouched. More details can be found in the respective changelogs. This patch (of 8): This is a preparatory patch that introduces two new functions: memory_block_online() and memory_block_offline(). For now, these functions will only call online_pages() and offline_pages() respectively, but they will be later in charge of preparing the vmemmap pages, carrying out the initialization and proper accounting of such pages. Since memory_block struct contains all the information, pass this struct down the chain till the end functions.

2021-05-05gpio: Add Realtek Otto GPIO supportSander Vanheule
Realtek MIPS SoCs (platform name Otto) have GPIO controllers with up to 64 GPIOs, divided over two banks. Each bank has a set of registers for 32 GPIOs, with support for edge-triggered interrupts. Each GPIO bank consists of four 8-bit GPIO ports (ABCD and EFGH). Most registers pack one bit per GPIO, except for the IMR register, which packs two bits per GPIO (AB-CD). Although the byte order is currently assumed to have port A..D at offset 0x0..0x3, this has been observed to be reversed on other, Lexra-based, SoCs (e.g. RTL8196E/97D/97F). Interrupt support is disabled for the fallback devicetree-compatible 'realtek,otto-gpio'. This allows for quick support of GPIO banks in which the byte order would be unknown. In this case, the port ordering in the IMR registers may not match the reversed order in the other registers (DCBA, and BA-DC or DC-BA).

2021-05-05HID: semitek: new driver for GK6X series keyboardsBenjamin Moody
A number of USB keyboards, using the Semitek firmware, are capable of handling arbitrary N-key rollover, but due to a buggy report descriptor, keys beyond the sixth cannot be detected by the generic HID driver. There are numerous hardware variants sold by several vendors, mostly using generic names like "GK61" for the 61-key version. These keyboards are sometimes known collectively as the "GK6X" series. The keyboard has three USB interfaces. Interface 0 uses the standard HID boot protocol, limited to eight modifier keys and six normal keys; interface 2 uses a custom report format that permits any number of keys. If more than six keys are pressed simultaneously, the first six are reported via interface 0 while subsequent keys are reported via interface 2. (Interface 1 uses a custom protocol for reprogramming the keyboard; this can be controlled through userspace tools and is not of concern for the present driver.) The report descriptor for interface 2, however, is incorrect (for report ID 0x04, the input field is marked as "array" rather than "variable".) The descriptor appears to be correct in other respects, so we simply replace the incorrect byte before parsing the descriptor.
