Arnd Bergmann 6760856791 [PATCH] introduce kernel_execve
The use of execve() in the kernel is dubious, since it relies on the
__KERNEL_SYSCALLS__ mechanism that stores the result in a global errno
variable.  As a first step of getting rid of this, change all users to a
global kernel_execve function that returns a proper error code.

This function is a terrible hack, and a later patch removes it again after the
kernel syscalls are gone.

Rafael J. Wysocki 6e1819d615 [PATCH] swsusp: userland interface
This patch introduces a user space interface for swsusp.

The interface is based on a special character device, called the snapshot
device, that allows user space processes to perform suspend and resume-related
operations with the help of some ioctls and the read()/write() functions.
 Additionally it allows these processes to allocate free swap pages from a
selected swap partition, called the resume partition, so that they know which
sectors of the resume partition are available to them.

The interface uses the same low-level system memory snapshot-handling
functions that are used by the built-it swap-writing/reading code of swsusp.

The interface documentation is included in the patch.

The patch assumes that the major and minor numbers of the snapshot device will
be 10 (ie.  misc device) and 231, the registration of which has already been
requested.

Jay Lan f220ab2a51 [PATCH] Improper initrd failure message at boot time
On system boot up, there was an failure reported to boot.msg:

     <5>Trying to move old root to /initrd ... failed

According to initrd(4) man page, step #7 of BOOT-UP OPERATION
is described as below:
          7. If the normal root file has directory /initrd, device
          /dev/ram0 is moved from  /  to  /initrd.   Otherwise  if
          directory  /initrd  does  not  exist device /dev/ram0 is
          unmounted.

We got service calls from customers concerning about this failure message
at boot time.  Many systems do not have /initrd and thus the message can be
changed in the case of non-existing /initrd so that it does not sound like
a failure of the system.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
