2021-06-20dt-bindings: i2c: renesas,iic: Always declare generic compatibilityGeert Uytterhoeven1-5/+0
According to the Hardware User's Manual, automatic transmission for PMIC control (DVFS) is not available on the R-Car E3 and RZ/G2E SoC. Experiments showed this really means that support for automatic DVFS is not present, while the IIC automatic transmission feature itself is still available, albeit not super useful. Hence there is no longer a reason not to declare compatibility with the R-Car Gen3-specific and generic versions, and the corresponding paragraph can be dropped.

But kernel is mapped in PMD SIZE, when bpf_jit_binary_lock_ro() is called to make the first bpf jit prog ROX, we will make part of kernel .data section RO too, so when we write to, for example memset the .data section, MMU will trigger a store page fault. To fix the issue, we need to ensure the BPF JIT region is PMD size aligned. This patch acchieve this goal by restoring the BPF JIT region to original position, I.E the 128MB before kernel .text section. The modification to kasan_init.c is inspired by Alexandre.

2021-06-18drm/i915: Move priolist to new i915_sched_engine objectMatthew Brost1-0/+5
Introduce i915_sched_engine object which is lower level data structure that i915_scheduler / generic code can operate on without touching execlist specific structures. This allows additional submission backends to be added without breaking the layering. Currently the execlists backend uses 1 of these object per each engine (physical or virtual) but future backends like the GuC will point to less instances utilizing the reference counting. This is a bit of detour to integrating the i915 with the DRM scheduler but this object will still exist when the DRM scheduler lands in the i915. It will however look a bit different. It will encapsulate the drm_gpu_scheduler object plus and common variables (to the backends) related to scheduling. Regardless this is a step in the right direction. This patch starts the aforementioned transition by moving the priolist into the i915_sched_engine object. v3: (Jason Ekstrand) Update comment next to intel_engine_cs.virtual Add kernel doc (Checkpatch) Fix double the in commit message v4: (Daniele) Update comment message.

2021-06-18bpf: Add documentation for libbpf including API autogenGrant Seltzer5-0/+253
This patch is meant to start the initiative to document libbpf. It includes .rst files which are text documentation describing building, API naming convention, as well as an index to generated API documentation. In this approach the generated API documentation is enabled by the kernels existing kernel documentation system which uses sphinx. The resulting docs would then be synced to kernel.org/doc You can test this by running `make htmldocs` and serving the html in Documentation/output. Since libbpf does not yet have comments in kernel doc format, see kernel.org/doc/html/latest/doc-guide/kernel-doc.html for an example so you can test this. The advantage of this approach is to use the existing sphinx infrastructure that the kernel has, and have libbpf docs in the same place as everything else. The current plan is to have the libbpf mirror sync the generated docs and version them based on the libbpf releases which are cut on github. This patch includes the addition of libbpf_api.rst which pulls comment documentation from header files in libbpf under tools/lib/bpf/. The comment docs would be of the standard kernel doc format.

To be able to debug long-running CS better, without changing the userspace code, we are adding a new option through debugfs interface to skip the reset of the device in case of CS timeout.

2021-06-18mxser: drop ISA supportJiri Slaby1-98/+9
While mxser PCI cards are still around and produced (Moxa provided me with two recently), ISA cards are obsolete for a long time. I haven't seen anyone using the cards and the ISA code paths are barely tested. Hence, remove ISA support from mxser driver so that we can clean the driver up.
