The || condition in hdev->fd_active_type != HCLGE_FD_ARFS_ACTIVE || hdev->fd_active_type != HCLGE_FD_RULE_NONE will always be true because hdev->fd_active_type cannot be equal to two different values at the same time.

2020-12-14net: mscc: ocelot: install MAC addresses in .ndo_set_rx_mode from process ↵Vladimir Oltean2-3/+84
context Currently ocelot_set_rx_mode calls ocelot_mact_learn directly, which has a very nice ocelot_mact_wait_for_completion at the end. Introduced in commit 639c1b2625af ("net: mscc: ocelot: Register poll timeout should be wall time not attempts"), this function uses readx_poll_timeout which triggers a lot of lockdep warnings and is also dangerous to use from atomic context, potentially leading to lockups and panics. Steen Hegelund added a poll timeout of 100 ms for checking the MAC table, a duration which is clearly absurd to poll in atomic context. So we need to defer the MAC table access to process context, which we do via a dynamically allocated workqueue which contains all there is to know about the MAC table operation it has to do.

2020-12-14bnxt_en: Enable batch mode when using HWRM_NVM_MODIFY to flash packages.Michael Chan1-9/+40
The current scheme allocates a DMA buffer as big as the requested firmware package file and DMAs the contents to firmware in one operation. The buffer size can be several hundred kilo bytes and the driver may not be able to allocate the memory. This will cause firmware upgrade to fail. Improve the scheme by using smaller DMA blocks and calling firmware to DMA each block in a batch mode. Older firmware can cause excessive NVRAM erases if the block size is too small so we try to allocate a 256K buffer to begin with and size it down successively if we cannot allocate the memory.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: - Expose tag address bits in siginfo. The original arm64 ABI did not expose any of the bits 63:56 of a tagged address in siginfo. In the presence of user ASAN or MTE, this information may be useful. The implementation is generic to other architectures supporting tags (like SPARC ADI, subject to wiring up the arch code). The user will have to opt in via sigaction(SA_EXPOSE_TAGBITS) so that the extra bits, if available, become visible in si_addr. - Default to 32-bit wide ZONE_DMA. Previously, ZONE_DMA was set to the lowest 1GB to cope with the Raspberry Pi 4 limitations, to the detriment of other platforms. With these changes, the kernel scans the Device Tree dma-ranges and the ACPI IORT information before deciding on a smaller ZONE_DMA. - Strengthen READ_ONCE() to acquire when CONFIG_LTO=y. When building with LTO, there is an increased risk of the compiler converting an address dependency headed by a READ_ONCE() invocation into a control dependency and consequently allowing for harmful reordering by the CPU. - Add CPPC FFH support using arm64 AMU counters. - set_fs() removal on arm64. This renders the User Access Override (UAO) ARMv8 feature unnecessary. - Perf updates: PMU driver for the ARM DMC-620 memory controller, sysfs identifier file for SMMUv3, stop event counters support for i.MX8MP, enable the perf events-based hard lockup detector. - Reorganise the kernel VA space slightly so that 52-bit VA configurations can use more virtual address space. - Improve the robustness of the arm64 memory offline event notifier. - Pad the Image header to 64K following the EFI header definition updated recently to increase the section alignment to 64K. - Support CONFIG_CMDLINE_EXTEND on arm64. - Do not use tagged PC in the kernel (TCR_EL1.TBID1==1), freeing up 8 bits for PtrAuth. - Switch to vmapped shadow call stacks. - Miscellaneous clean-ups. * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (78 commits) perf/imx_ddr: Add system PMU identifier for userspace bindings: perf: imx-ddr: add compatible string arm64: Fix build failure when HARDLOCKUP_DETECTOR_PERF is enabled arm64: mte: fix prctl(PR_GET_TAGGED_ADDR_CTRL) if TCF0=NONE arm64: mark __system_matches_cap as __maybe_unused arm64: uaccess: remove vestigal UAO support arm64: uaccess: remove redundant PAN toggling arm64: uaccess: remove addr_limit_user_check() arm64: uaccess: remove set_fs() arm64: uaccess cleanup macro naming arm64: uaccess: split user/kernel routines arm64: uaccess: refactor __{get,put}_user arm64: uaccess: simplify __copy_user_flushcache() arm64: uaccess: rename privileged uaccess routines arm64: sdei: explicitly simulate PAN/UAO entry arm64: sdei: move uaccess logic to arch/arm64/ arm64: head.S: always initialize PSTATE arm64: head.S: cleanup SCTLR_ELx initialization arm64: head.S: rename el2_setup -> init_kernel_el arm64: add C wrappers for SET_PSTATE_*() ...

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Heiko Carstens: - Add support for the hugetlb_cma command line option to allocate gigantic hugepages using CMA - Add arch_get_random_long() support. - Add ap bus userspace notifications. - Increase default size of vmalloc area to 512GB and otherwise let it increase dynamically by the size of physical memory. This should fix all occurrences where the vmalloc area was not large enough. - Completely get rid of set_fs() (aka select SET_FS) and rework address space handling while doing that; making address space handling much more simple. - Reimplement getcpu vdso syscall in C. - Add support for extended SCLP responses (> 4k). This allows e.g. to handle also potential large system configurations. - Simplify KASAN by removing 3-level page table support and only supporting 4-levels from now on. - Improve debug-ability of the kernel decompressor code, which now prints also stack traces and symbols in case of problems to the console. - Remove more power management leftovers. - Other various fixes and improvements all over the place. * tag 's390-5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (62 commits) s390/mm: add support to allocate gigantic hugepages using CMA s390/crypto: add arch_get_random_long() support s390/smp: perform initial CPU reset also for SMT siblings s390/mm: use invalid asce for user space when switching to init_mm s390/idle: fix accounting with machine checks s390/idle: add missing mt_cycles calculation s390/boot: add build-id to decompressor s390/kexec_file: fix diag308 subcode when loading crash kernel s390/cio: fix use-after-free in ccw_device_destroy_console s390/cio: remove pm support from ccw bus driver s390/cio: remove pm support from css-bus driver s390/cio: remove pm support from IO subchannel drivers s390/cio: remove pm support from chsc subchannel driver s390/vmur: remove unused pm related functions s390/tape: remove unsupported PM functions s390/cio: remove pm support from eadm-sch drivers s390: remove pm support from console drivers s390/dasd: remove unused pm related functions s390/zfcp: remove pm support from zfcp driver s390/ap: let bus_register() add the AP bus sysfs attributes ...

2020-12-14Merge branch 'radeon-fixes' (Radeon and amdgpu fixes)Linus Torvalds2-60/+47
Merge radeon and amdgpu fixes for boot problems. The drm merge ended up causing my AMD workstation to not boot. When reporting this, Alex Deucher correctly blamed commit 28a68f828266 ("drm/radeon/ttm: use multihop") and pointed to these two fixes that were already in the drm-misc tree: 95e3d610d35c ("drm/radeon: fix check order in radeon_bo_move") aefec40938e4 ("drm/amdgpu: fix check order in amdgpu_bo_move") Since I hate doing merges with a known-bad base, I've cherry-picked these fixes into a branch of their own, just to be able to continue my merge window. The original commits will eventually come in as duplicates through the normal channels, but in the meantime we have a tree that isn't broken with basically every AMD GPU out there.
