Subject: [PATCH] mm/process_vm_access: move config option into init/Kconfig
Date: Tue, 27 May 2014 18:13:13 +0400 [thread overview]
Message-ID: <20140527141313.23853.29306.stgit@zurg> (raw)
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.
