      "message": "Kconfig: consolidate CONFIG_DEBUG_STRICT_USER_COPY_CHECKS\n\nThe help text for this config is duplicated across the x86, parisc, and\ns390 Kconfig.debug files.  Arnd Bergman noted that the help text was\nslightly misleading and should be fixed to state that enabling this\noption isn\u0027t a problem when using pre 4.4 gcc.\n\nTo simplify the rewording, consolidate the text into lib/Kconfig.debug\nand modify it there to be more explicit about when you should say N to\nthis config.\n\nAlso, make the text a bit more generic by stating that this option\nenables compile time checks so we can cover architectures which emit\nwarnings vs.  ones which emit errors.  The details of how an\narchitecture decided to implement the checks isn\u0027t as important as the\nconcept of compile time checking of copy_from_user() calls.\n\nWhile we\u0027re doing this, remove all the copy_from_user_overflow() code\nthat\u0027s duplicated many times and place it into lib/ so that any\narchitecture supporting this option can get the function for free.\n\nSigned-off-by: Stephen Boyd \u003csboyd@codeaurora.org\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: Ingo Molnar \u003cmingo@kernel.org\u003e\nAcked-by: H.
