sys_sgetmask/sys_ssetmask: add CONFIG_SGETMASK_SYSCALL

2014-06-04T23:54:14Z

sys_sgetmask and sys_ssetmask are obsolete system calls no longer supported in libc. This patch replaces architecture related __ARCH_WANT_SYS_SGETMAX by expert mode configuration.That option is enabled by default for those architectures.

mm/process_vm_access: move config option into init/Kconfig

2014-06-04T23:54:12Z

CONFIG_CROSS_MEMORY_ATTACH adds couple syscalls: process_vm_readv and process_vm_writev, it's a kind of IPC for copying data between processes. Currently this option is placed inside "Processor type and features". This patch moves it into "General setup" (where all other arch-independed syscalls and ipc features are placed) and changes prompt string to less cryptic.

memcg: kill CONFIG_MM_OWNER

2014-06-04T23:54:01Z

CONFIG_MM_OWNER makes no sense. It is not user-selectable, it is only selected by CONFIG_MEMCG automatically. So we can kill this option in init/Kconfig and do s/CONFIG_MM_OWNER/CONFIG_MEMCG/ globally.

Documentation/memcg: warn about incomplete kmemcg state

2014-06-04T23:54:00Z

Kmemcg is currently under development and lacks some important features. In particular, it does not have support of kmem reclaim on memory pressure inside cgroup, which practically makes it unusable in real life. Let's warn about it in both Kconfig and Documentation to prevent complaints arising.

init/Kconfig: move the trusted keyring config option to general setup

2014-04-18T23:40:07Z

The SYSTEM_TRUSTED_KEYRING config option is not in any menu, causing it to show up in the toplevel of the kernel configuration. Fix this by moving it under the General Setup menu. Signed-off-by: Peter Foley Cc: David Howells Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT

2014-04-07T23:36:09Z

"make allnoconfig" exists to ease testing of minimal configurations. Documentation/SubmitChecklist includes a note to test with allnoconfig. This helps catch missing dependencies on common-but-not-required functionality, which might otherwise go unnoticed. However, allnoconfig still leaves many symbols enabled, because they're hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT. For instance, allnoconfig still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't typically get build-tested with those disabled. To address this, introduce a new Kconfig option "allnoconfig_y", used on symbols which only exist to hide other symbols. Set it on CONFIG_EMBEDDED (which then selects CONFIG_EXPERT). allnoconfig will then disable all the symbols hidden behind those. Signed-off-by: Josh Triplett Tested-by: Paul E.
