-Subject: [PATCH] Add support for using seccomp_bpf on mips64el.
-
-Currently, seccomp_bpf is not supported on mips64el, and the build
-configuration sets use_seccomp_bpf=false on mips64el. This CL adds
-support for seccomp-bpf on mips64el, and resolves many compiler errors
-when compiling on mips64el.
-
-This patch merge into chromium master branch:
-https://chromium.googlesource.com/chromium/src/+/534d7ce2af699715acfc4fe516ef3c2ffee65bc5

-    sqlite: Refactor BUILD.gn.
-    
-    This CL contains the following refactorings.
-    
-    1) The preprocessor defines ("compile-time options" in the SQLite
-       documentation [1]) used to build the SQLite library bundled with Chromium
-       are extracted in a "chromium_sqlite3_compile_options" configuration.
-    
-    2) The "chromium_sqlite3_compile_options" configuration is injected into
-       all the targets that depend on //third_party/sqlite (when using
-       Chromium's bundled SQLite library), so sqlite.h is parsed with the
-       same preprocessor defines used to compile the library. This will
-       become important when we start disabling the SQLite features we don't
-       use.
-    
-    3) The SQLite shell is compiled with the same preprocessor defines and
-       disabled warnings as the SQLite library. The shell is only built on
-       Linux for the purpose of debugging SQLite issues, and does not ship
-       with Chrome.
-    
-    4) The configuration used when we rely on the system's SQLite library
-       (so the SQLite bundled with Chromium is not built) is renamed from
-       "sqlite_config" to "system_sqlite_config".
-
