Context Navigation

source: trunk/kernel/kern/rpc.c @ 622

Last change on this file since 622 was 619, checked in by alain, 6 years ago

1) Fix a bug in KSH : after the "load" command,

the [ksh] prompt is now printed after completion
of the loaded application.

2) Fix a bug in vmm_handle_cow() : the copy-on-write

use now a hal_remote_memcpy() to replicate the page content.
