From 226b4ccdcb6371645c25ec99b59bfde65987318c Mon Sep 17 00:00:00 2001 From: Konstantin Khlebnikov Date: Wed, 4 Jun 2014 16:10:50 -0700 Subject: [PATCH] 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.
