This intruduces 82xx family in arch/powerpc/platforms,
and has all the board-specific code to represent regression-less
transaction from ppc. The functionality is apparently the same, including
PCI controller.

It was obesrved that at least one older PCI card predating the
requirement for the TRDY signal to respond within 16 clock ticks actually
does not meet this rule nor even the power-on defaults of the PCI bridges
found in development systems built around the Broadcom SiByte SOCs. Here
is a patch that bumps up the timeout to the highest finite value supported
by these chips, which is 255 clock ticks. The bridges affected are the
SiByte SOC itself and the SP1011.
This change does not effectively affect systems only having PCI option
cards installed that meet the TRDY requirement of the current PCI spec.
The rule was introduced with PCI 2.1, so any older card may make the
system affected. If this is the case, performance of the system will
suffer in return for the card working at all. If this is a concern, then
the solution is not to use such cards.

Jesper Juhl reported that testing the software math-emulation by forcing
"no387" doesn't work on modern CPU's.
The reason was two-fold:
- you also need to pass in "nofxsr" to make sure that we not only don't
touch the old i387 legacy hardware, it also needs to disable the
modern XMM/FXSR sequences
- "nofxsr" didn't actually clear the capability bits immediately,
leaving the early boot sequence still using FXSR until we got to
the identify_cpu() stage.
This fixes the "nofxsr" flag to take effect immediately on the boot CPU.

It looks like Zach Brown's patch pr_debug-check-pr_debug-arguments
worked as inteded. That is, it doesn't "allow completely incorrect code

The last change for partport_pc did fix the common case for all PowerMacs,
but it broke the case for PCI multiport IO cards. In fact, the config
option CONFIG_PARPORT_PC_SUPERIO=y lead to a hard crash when cups probed
the parport driver. It enables the winbond and smsc probing.
Remove the PARPORT_BASE check again, parport_pc_find_nonpci_ports() will
take care of it. All powerpc configs should have
CONFIG_PARPORT_PC_SUPERIO=n, the code did not find anything on the chrp
boards we tested it on.

These patches make the kernel pass 64-bit inode numbers internally when
communicating to userspace, even on a 32-bit system. They are required
because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS
for example. The 64-bit inode numbers are then propagated to userspace
automatically where the arch supports it.
Problems have been seen with userspace (eg: ld.so) using the 64-bit inode
number returned by stat64() or getdents64() to differentiate files, and
failing because the 64-bit inode number space was compressed to 32-bits, and
so overlaps occur.
This patch:
Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit
inode number so that 64-bit inode numbers can be passed back to userspace.
The stat functions then returns the full 64-bit inode number where
available and where possible. If it is not possible to represent the inode
number supplied by the filesystem in the field provided by userspace, then
error EOVERFLOW will be issued.
Similarly, the getdents/readdir functions now pass the full 64-bit inode
number to userspace where possible, returning EOVERFLOW instead when a
directory entry is encountered that can't be properly represented.
Note that this means that some inodes will not be stat'able on a 32-bit
system with old libraries where they were before - but it does mean that
there will be no ambiguity over what a 32-bit inode number refers to.
Note similarly that directory scans may be cut short with an error on a
32-bit system with old libraries where the scan would work before for the
same reasons.
It is judged unlikely that this situation will occur because modern glibc
uses 64-bit capable versions of stat and getdents class functions
exclusively, and that older systems are unlikely to encounter
unrepresentable inode numbers anyway.

Revert Andrew Morton's patch to temporarily hack around the lack of a
declaration of sigset_t in linux/compat.h to make the block-disablement
patches build on IA64. This got accidentally pushed to Linus and should
be fixed in a different manner.
Also make linux/compat.h #include asm/signal.h to gain a definition of
sigset_t so that it can externally declare sigset_from_compat().
This has been compile-tested for i386, x86_64, ia64, mips, mips64, frv, ppc and

There are a few places in the kernel where the init task is signaled. The
ctrl+alt+del sequence is one them. It kills a task, usually init, using a
cached pid (cad_pid).
This patch replaces the pid_t by a struct pid to avoid pid wrap around
problem. The struct pid is initialized at boot time in init() and can be
modified through systctl with
/proc/sys/kernel/cad_pid
[ I haven't found any distro using it ? ]
It also introduces a small helper routine kill_cad_pid() which is used
where it seemed ok to use cad_pid instead of pid 1.

sh64 is using system call macros to call some functions from the kernel.
The old debug code can simply be removed, since we don't really have that much
of a need for it anymore, it was mostly something that was handy during the
initial bringup. This also brings us closer to something that looks like
readable code again..
I also added a sane kernel_thread() implementation that gets away from this,
so that should take care of sh64 at least.

This adds the new kernel_execve function on all architectures that were using
_syscall3() to implement execve.
The implementation uses code from the _syscall3 macros provided in the
unistd.h header file. I don't have cross-compilers for any of these
architectures, so the patch is untested with the exception of i386.
Most architectures can probably implement this in a nicer way in assembly or
by combining it with the sys_execve implementation itself, but this should do
it for now.

Some architectures provide an execve function that does not set errno, but
instead returns the result code directly. Rename these to kernel_execve to
get the right semantics there. Moreover, there is no reasone for any of these
architectures to still provide __KERNEL_SYSCALLS__ or _syscallN macros, so
remove these right away.

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.

In some places, particularly drivers and __init code, the init utsns is the
appropriate one to use. This patch replaces those with a the init_utsname
helper.
Changes: Removed several uses of init_utsname(). Hope I picked all the
right ones in net/ipv4/ipconfig.c. These are now changed to
utsname() (the per-process namespace utsname) in the previous
patch (2/7)

Replace references to system_utsname to the per-process uts namespace
where appropriate. This includes things like uname.
Changes: Per Eric Biederman's comments, use the per-process uts namespace
for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c

Move the init_nsproxy definition out of arch/ into kernel/nsproxy.c. This
avoids all arches having to be updated. Compiles and boots on s390.

This patch adds a nsproxy structure to the task struct. Later patches will
move the fs namespace pointer into this structure, and introduce a new utsname
namespace into the nsproxy.
The vserver and openvz functionality, then, would be implemented in large part
by virtualizing/isolating more and more resources into namespaces, each
contained in the nsproxy.
