From: Konstantin Khlebnikov Date: Wed, 4 Jun 2014 23:10:50 +0000 (-0700) Subject: mm/process_vm_access: move config option into init/Kconfig X-Git-Tag: v3.16-rc1~47^2~16^2~89 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=226b4ccdcb6371645c25ec99b59bfde65987318c;p=platform%2Fkernel%2Flinux-exynos.git mm/process_vm_access: move config option into init/Kconfig 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.
