2020-06-30dt-bindings: copy process-schema-examples.yaml to process-schema.yamlMasahiro Yamada1-8/+20
There are two processed schema files: - processed-schema-examples.yaml Used for 'make dt_binding_check'. This is always a full schema. - processed-schema.yaml Used for 'make dtbs_check'. This may be a full schema, or a smaller subset if DT_SCHEMA_FILES is given by a user. If DT_SCHEMA_FILES is not specified, they are the same. You can copy the former to the latter instead of running dt-mk-schema twice. This saves the cpu time a lot when you do 'make dt_binding_check dtbs_check' because building the full schema takes a couple of seconds. If DT_SCHEMA_FILES is specified, processed-schema.yaml is generated based on the specified yaml files.

Currently, processed-schema.yaml is always built, but it is actually used only for 'make dtbs_check'. 'make dt_binding_check' uses processed-schema-example.yaml instead.

2020-06-30dt-bindings: fix error in 'make clean' after 'make dt_binding_check'Masahiro Yamada1-0/+5
We are having more and more schema files. Commit 8b6b80218b01 ("dt-bindings: Fix command line length limit calling dt-mk-schema") fixed the 'Argument list too long' error of the schema checks, but the same error happens while cleaning too. 'make clean' after 'make dt_binding_check' fails as follows: $ make dt_binding_check [ snip ] $ make clean make[2]: execvp: /bin/sh: Argument list too long make[2]: *** [scripts/Makefile.clean:52: __clean] Error 127 make[1]: *** [scripts/Makefile.clean:66: Documentation/devicetree/bindings] Error 2 make: *** [Makefile:1763: _clean_Documentation] Error 2 'make dt_binding_check' generates so many .example.dts, .dt.yaml files, which are passed to the 'rm' command when you run 'make clean'.

Pull x86 entry fixes from Borislav Petkov: "This is the x86/entry urgent pile which has accumulated since the merge window. It is not the smallest but considering the almost complete entry core rewrite, the amount of fixes to follow is somewhat higher than usual, which is to be expected. Peter Zijlstra says: 'These patches address a number of instrumentation issues that were found after the x86/entry overhaul. When combined with rcu/urgent and objtool/urgent, these patches make UBSAN/KASAN/KCSAN happy again. Part of making this all work is bumping the minimum GCC version for KASAN builds to gcc-8.3, the reason for this is that the __no_sanitize_address function attribute is broken in GCC releases before that. No known GCC version has a working __no_sanitize_undefined, however because the only noinstr violation that results from this happens when an UB is found, we treat it like WARN.

Since commit 3917c80280c9 ("thp: change CoW semantics for anon-THP"), THP CoW page fault is rewritten. Now it just splits pmd then fallback to base page fault, it doesn't try to allocate THP anymore. So it is no longer counted in THP_FAULT_ALLOC. Remove the obsolete statement in documentation about THP CoW allocation to avoid confusion.
