Fix SPI driver to work with SPI flash ST M25P16 on bf548 Currently the SPI driver enables the SPI controller and sets the SPI baud register for each SPI transfer. But they should never be changed within a SPI message session, in which several SPI transfers are pumped.

2007-12-05fix clone(CLONE_NEWPID)Eric W. Biederman
Currently we are complicating the code in copy_process, the clone ABI, and if we fix the bugs sys_setsid itself, with an unnecessary open coded version of sys_setsid. So just simplify everything and don't special case the session and pgrp of the initial process in a pid namespace. Having this special case actually presents to user space the classic linux startup conditions with session == pgrp == 0 for /sbin/init. We already handle sending signals to processes in a child pid namespace. We need to handle sending signals to processes in a parent pid namespace for cases like SIGCHILD and SIGIO. This makes nothing extra visible inside a pid namespace. So this extra special case appears to have no redeeming merits. Further removing this special case increases the flexibility of how we can use pid namespaces, by not requiring the initial process in a pid namespace to be a daemon. Signed-off-by: Eric W.

This kills GRUB, and probably other stuff. But it all happens *before* Linux is even loaded.
