lib/Kconfig.debug: Restrict FRAME_POINTER for MIPS

2013-07-28T23:30:12Z

commit 25c87eae1725ed77a8b44d782a86abdc279b4ede upstream. FAULT_INJECTION_STACKTRACE_FILTER selects FRAME_POINTER but that symbol is not available for MIPS. Fixes the following problem on a randconfig: warning: (LOCKDEP && FAULT_INJECTION_STACKTRACE_FILTER && LATENCYTOP && KMEMCHECK) selects FRAME_POINTER which has unmet direct dependencies (DEBUG_KERNEL && (CRIS || M68K || FRV || UML || AVR32 || SUPERH || BLACKFIN || MN10300 || METAG) || ARCH_WANT_FRAME_POINTERS) Signed-off-by: Markos Chandras Acked-by: Steven J.

Kconfig: consolidate CONFIG_DEBUG_STRICT_USER_COPY_CHECKS

2013-05-01T00:04:09Z

The help text for this config is duplicated across the x86, parisc, and s390 Kconfig.debug files. Arnd Bergman noted that the help text was slightly misleading and should be fixed to state that enabling this option isn't a problem when using pre 4.4 gcc. To simplify the rewording, consolidate the text into lib/Kconfig.debug and modify it there to be more explicit about when you should say N to this config. Also, make the text a bit more generic by stating that this option enables compile time checks so we can cover architectures which emit warnings vs. ones which emit errors. The details of how an architecture decided to implement the checks isn't as important as the concept of compile time checking of copy_from_user() calls. While we're doing this, remove all the copy_from_user_overflow() code that's duplicated many times and place it into lib/ so that any architecture supporting this option can get the function for free.

lib/string_helpers: introduce generic string_unescape

2013-05-01T00:04:03Z

There are several places in kernel where modules unescapes input to convert C-Style Escape Sequences into byte codes. The patch provides generic implementation of such approach. Test cases are also included into the patch.
