2020-10-06dma-mapping: split <linux/dma-mapping.h>Christoph Hellwig
Split out all the bits that are purely for dma_map_ops implementations and related code into a new <linux/dma-map-ops.h> header so that they don't get pulled into all the drivers. That also means the architecture specific <asm/dma-mapping.h> is not pulled in by <linux/dma-mapping.h> any more, which leads to a missing includes that were pulled in by the x86 or arm versions in a few not overly portable drivers.

2020-10-05RDMA/umem: Move to allocate SG table from pagesMaor Gottlieb
Remove the implementation of ib_umem_add_sg_table and instead call to __sg_alloc_table_from_pages which already has the logic to merge contiguous pages. Besides that it removes duplicated functionality, it reduces the memory consumption of the SG table significantly. Prior to this patch, the SG table was allocated in advance regardless consideration of contiguous pages. In huge pages system of 2MB page size, without this change, the SG table would contain x512 SG entries. E.g. for 100GB memory registration: Number of entries Size Before 26214400 600.0MB After 51200 1.2MB Link: https://lore.kernel.org/r/20201004154340.1080481-5-leon@kernel.org Signed-off-by: Maor Gottlieb <maorg@nvidia.com> Signed-off-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
2020-10-05lib/scatterlist: Add support in dynamic allocation of SG table from pagesMaor Gottlieb
Extend __sg_alloc_table_from_pages to support dynamic allocation of SG table from pages. It should be used by drivers that can't supply all the pages at one time. This function returns the last populated SGE in the table. Users should pass it as an argument to the function from the second call and forward. As before, nents will be equal to the number of populated SGEs (chunks). With this new extension, drivers can benefit the optimization of merging contiguous pages without a need to allocate all pages in advance and hold them in a large buffer. E.g. with the Infiniband driver that allocates a single page for hold the pages. For 1TB memory registration, the temporary buffer would consume only 4KB, instead of 2GB.

2020-10-05drm/amd/display: HDMI remote sink need mode validation for LinuxFangzhi Zuo
[Why] Currently mode validation is bypassed if remote sink exists. That leads to mode set issue when a BW bottle neck exists in the link path, e.g., a DP-to-HDMI converter that only supports HDMI 1.4. Any invalid mode passed to Linux user space will cause the modeset failure due to limitation of Linux user space implementation. [How] Mode validation is skipped only if in edid override. For real remote sink, clock limit check should be done for HDMI remote sink. Have HDMI related remote sink going through mode validation to elimiate modes which pixel clock exceeds BW limitation.

2020-10-05drm/amd/display: Avoid set zero in the requested clkRodrigo Siqueira
[Why] Sometimes CRTCs can be disabled due to display unplugging or temporarily transition in the userspace; in these circumstances, DCE tries to set the minimum clock threshold. When we have this situation, the function bw_calcs is invoked with number_of_displays set to zero, making DCE set dispclk_khz and sclk_khz to zero. For these reasons, we have seen some ATOM bios errors that look like: [drm:atom_op_jump [amdgpu]] *ERROR* atombios stuck in loop for more than 5secs aborting [drm:amdgpu_atom_execute_table_locked [amdgpu]] *ERROR* atombios stuck executing EA8A (len 761, WS 0, PS 0) @ 0xEABA [How] This error happens due to an attempt to optimize the bandwidth using the sclk, and the dispclk clock set to zero. Technically we handle this in the function dce112_set_clock, but we are not considering the case that this value is set to zero. This commit fixes this issue by ensuring that we never set a minimum value below the minimum clock threshold.

2020-10-05drm/amdgpu: align frag_end to covered address spaceAlex Sierra
align frag_end to the next pd when there are no page table entries on the current pde. This fixes invalidation of larger address space areas where some page tables are allocated and other aren't.

2020-10-05drm/amdgpu: fix NULL pointer dereference for RenoirDirk Gouders
Commit c1cf79ca5ced46 ("drm/amdgpu: use IP discovery table for renoir") introduced a NULL pointer dereference when booting with amdgpu.discovery=0, because it removed the call of vega10_reg_base_init() for that case. Fix this by calling that funcion if amdgpu_discovery == 0 in addition to the case that amdgpu_discovery_reg_base_init() failed.

2020-10-05leds: lm3697: Fix out-of-bound accessGabriel David
If both LED banks aren't used in device tree, an out-of-bounds condition in lm3697_init occurs because of the for loop assuming that all the banks are used. Fix it by adding a variable that contains the number of used banks.

Pull networking fixes from David Miller: 1) Make sure SKB control block is in the proper state during IPSEC ESP-in-TCP encapsulation. From Sabrina Dubroca. 2) Various kinds of attributes were not being cloned properly when we build new xfrm_state objects from existing ones. Fix from Antony Antony. 3) Make sure to keep BTF sections, from Tony Ambardar. 4) TX DMA channels need proper locking in lantiq driver, from Hauke Mehrtens. 5) Honour route MTU during forwarding, always. From Maciej Żenczykowski. 6) Fix races in kTLS which can result in crashes, from Rohit Maheshwari. 7) Skip TCP DSACKs with rediculous sequence ranges, from Priyaranjan Jha. 8) Use correct address family in xfrm state lookups, from Herbert Xu. 9) A bridge FDB flush should not clear out user managed fdb entries with the ext_learn flag set, from Nikolay Aleksandrov. 10) Fix nested locking of netdev address lists, from Taehee Yoo. 11) Fix handling of 32-bit DATA_FIN values in mptcp, from Mat Martineau. 12) Fix r8169 data corruptions on RTL8402 chips, from Heiner Kallweit. 13) Don't free command entries in mlx5 while comp handler could still be running, from Eran Ben Elisha. 14) Error flow of request_irq() in mlx5 is busted, due to an off by one we try to free and IRQ never allocated. From Maor Gottlieb. 15) Fix leak when dumping netlink policies, from Johannes Berg. 16) Sendpage cannot be performed when a page is a slab page, or the page count is < 1.
