2020-11-03drivers/video: Fix -Wstringop-truncation in hdmi.cThomas Zimmermann
Trying to copy into the string fields with strncpy() gives a warning from gcc. Both fields are part of a packed HDMI header and do not require a terminating \0 character. ../drivers/video/hdmi.c: In function 'hdmi_spd_infoframe_init': ../drivers/video/hdmi.c:230:2: warning: 'strncpy' specified bound 8 equals destination size [-Wstringop-truncation] 230 | strncpy(frame->vendor, vendor, sizeof(frame->vendor)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/video/hdmi.c:231:2: warning: 'strncpy' specified bound 16 equals destination size [-Wstringop-truncation] 231 | strncpy(frame->product, product, sizeof(frame->product)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Just use memcpy() instead.

2020-11-03drm/panfrost: Remove unused variables in panfrost_job_close()Boris Brezillon
Commit a17d609e3e21 ("drm/panfrost: Don't corrupt the queue mutex on open/close") left unused variables behind, thus generating a warning at compilation time. Remove those variables.

2020-11-02drm: Remove SCATTERLIST_MAX_SEGMENTJason Gunthorpe
Since commit 9a40401cfa13 ("lib/scatterlist: Do not limit max_segment to PAGE_ALIGNED values") the max_segment input to sg_alloc_table_from_pages() does not have to be any special value. The new algorithm will always create something less than what the user provides. Thus eliminate this confusing constant. - vmwgfx should use the HW capability, not mix in the OS page size for calling dma_set_max_seg_size() - i915 uses i915_sg_segment_size() both for sg_alloc_table_from_pages and for some open coded sgl construction. This doesn't change the value since rounddown(size, UINT_MAX) == SCATTERLIST_MAX_SEGMENT - drm_prime_pages_to_sg uses it as a default if max_segment is zero, UINT_MAX is fine to use directly.

2020-11-02drm/nouveau/ttm: Add limits.hMaxime Ripard
It seems that a recent commit broke the nouveau compilation when swiotlb is disabled (which is the case on our ARM defconfig for example). Daniel says """ Since the proper fix is maybe stuck in the usual "drm abuses swiotlb internals" bikeshed, maybe best if we push a fix to including limits.h in nouveau and call it done? """ So let's go down the simplest path to fix our build, and goes back to it later if needed.

The fixes are for some reported issues in the interconnect and coresight drivers, nothing major. The "big" driver removal is the MIC drivers have been asked to be removed as the hardware never shipped and Intel no longer wants to maintain something that no one can use. This is welcomed by many as the DMA usage of these drivers was "interesting" and the security people were starting to question some issues that were starting to be found in the codebase. Note, one of the subsystems for this driver, the "VOP" code, will probably come back in future kernel versions as it was looking to potentially solve some PCIe virtualization issues that a number of other vendors were wanting to solve. But as-is, this codebase didn't work for anyone else so no actual functionality is being removed.

2020-10-31KVM: VMX: eVMCS: make evmcs_sanitize_exec_ctrls() work againVitaly Kuznetsov
It was noticed that evmcs_sanitize_exec_ctrls() is not being executed nowadays despite the code checking 'enable_evmcs' static key looking correct. Turns out, static key magic doesn't work in '__init' section (and it is unclear when things changed) but setup_vmcs_config() is called only once per CPU so we don't really need it to. Switch to checking 'enlightened_vmcs' instead, it is supposed to be in sync with 'enable_evmcs'. Opportunistically make evmcs_sanitize_exec_ctrls '__init' and drop unneeded extra newline from it.

2020-10-31KVM: selftests: test behavior of unmapped L2 APIC-access addressJim Mattson
Add a regression test for commit 671ddc700fd0 ("KVM: nVMX: Don't leak L1 MMIO regions to L2"). First, check to see that an L2 guest can be launched with a valid APIC-access address that is backed by a page of L1 physical memory. Next, set the APIC-access address to a (valid) L1 physical address that is not backed by memory. KVM can't handle this situation, so resuming L2 should result in a KVM exit for internal error (emulation).
