2013-04-30kernel/sys.c: make prctl(PR_SET_MM) generally availableAmnon Shiloh
The purpose of this patch is to allow privileged processes to set their own per-memory memory-region fields: start_code, end_code, start_data, end_data, start_brk, brk, start_stack, arg_start, arg_end, env_start, env_end. This functionality is needed by any application or package that needs to reconstruct Linux processes, that is, to start them in any way other than by means of an "execve()" from an executable file. This includes: 1. Restoring processes from a checkpoint-file (by all potential user-level checkpointing packages, not only CRIU's). 2. Restarting processes on another node after process migration. 3. Starting duplicated copies of a running process (for reliability and high-availablity). 4. Starting a process from an executable format that is not supported by Linux, thus requiring a "manual execve" by a user-level utility. 5. Similarly, starting a process from a networked and/or crypted executable that, for confidentiality, licensing or other reasons, may not be written to the local file-systems. The code that does that was already included in the Linux kernel by the CRIU group, in the form of "prctl(PR_SET_MM)", but prior to this was enclosed within their private "#ifdef CONFIG_CHECKPOINT_RESTORE", which is normally disabled. The patch removes those ifdefs.

2013-04-30menuconfig: print more info for symbol without promptsWengmeiling
When we search a config symbol, if it has no prompt the position of this symbol in the Kconfig file and it's dependencies are not printed. This can be inconvenient, especially when it's set to n and we want to find out why. the following is an example: before: Symbol: GENERIC_SMP_IDLE_THREAD [=y] Type : boolean Selected by: X86 [=y] after: Symbol: GENERIC_SMP_IDLE_THREAD [=y] Type : boolean Defined at arch/Kconfig:213 Selected by: X86 [=y] Signed-off-by: Weng Meiling <wengmeiling.weng@huawei.com> Signed-off-by: Libo Chen <libo.chen@huawei.com> Cc: Michal Marek <mmarek@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-04-30init/Kconfig: re-order CONFIG_EXPERT options to fix menuconfig displayMike Frysinger
The kconfig language requires that dependent options all follow the menuconfig symbol in order to be collapsed below it. Recently some hidden options were added below the EXPERT menuconfig, but did not depend on EXPERT (because hidden options can't). This broke the display. So re-order all these options, and while we're here stick the PCI quirks under the EXPERT menu (since it isn't sitting with any related options). Before this commit, we get: [*] Configure standard kernel features (expert users) ---> [ ] Sysctl syscall support [*] Load all symbols for debugging/ksymoops ... [ ] Embedded system Now we get the older (and correct) behavior: [*] Configure standard kernel features (expert users) ---> [ ] Embedded system And if you go into the expert menu you get the expert options: [ ] Sysctl syscall support [*] Load all symbols for debugging/ksymoops ...

2013-04-30Kconfig: consolidate CONFIG_DEBUG_STRICT_USER_COPY_CHECKSStephen Boyd
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.
