Clean up vfs_readv/writev() interface and avoid code duplication.

Make kNFSd use the cleaned-up interfaces, and disable the code that
accesses the low-level readpage() function of the exported filesystem
(not allowed - many filesystems need extra setup, which is why we have
a separate ->sendpage() routine for that).

Change ARCH_STACK_GROWSUP to CONFIG_STACK_GROWSUP as requested.

The hugetlb page support in 2.5.46 is broken (Don't know if this is the
first version of kernel or any prior revs also have that).  Basically the
free side of hugepages was really not freeing the physical resources (for
the cases when the pages allocated using system call interface).  Attached
is the patch that should resolve it. (doesn't break the hugetlbfs support
either).

NFSv2 doesn't pass connectathon 2002, at least on some Linux kernels.
Trond deemed the following modification necessary in all kernels to
address the problem.

New code in 2.5 VFS layer invokes notify_change to clear the suid and
sgid bits for every write request.  notify_change needs to optimize out
calls to ->setattr that don't do anything, because for many network file
systems, an on-the-wire SETATTR request is generated for every ->setattr
call, resulting in unnecessary latency for NFS writes.

nfsroot needs to pass the network protocol (UDP/TCP) into the mount
functions in order to support mounting root partitions via NFS over TCP.

This removes the old documentation, adds the new one and fixes all
references to it.

Various small kconfig updates to fix all the reported little problems and
the single menu mode for menuconfig by Petr Baudis <pasky@ucw.cz>.

This deletes the old config tools and moves Michael's maintainer entry
for them to CREDITS and I added myself for KCONFIG instead.

ethernet drivers used on powermacs.  The bmac.c change is just to
remove some compile warnings.  The mace.c change is to move an inline
function definition to before the point where it is used.

On PA-RISC, SIGRTMIN is 36, so a 32-bit data type is not enough.  We
conditionalise it so other arches don't pay the cost.

Add prefetching support to asm-generic/xor.h.  This gives a healthy speedup
on both PA-RISC & IA64.

- CREDITS & MAINTAINERS updates
- changes for the new kstat/dkstat struct
- Kconfig updates
- L_TARGET isn't obsolete yet
- fix the sys_truncate/truncate64 issue properly this time
- add MAP_POPULATE & MAP_NONBLOCK definitions

Support initramfs on parisc

C99 initialiser conversion; some from Rusty, some from me.

This adds some missing __exit specifications which lead to a failure to
link the AFS code directly into the kernel.

With these changes the boot wrapper successfully builds,
although this may not be the absolute best way to do things.

This didn't compile since sd_find_target is gone, and is to
move into userspace anyway.

This moves the sections which are read-only (e.g. exception table,
kallsyms data) to go before the read/write data section, and the
feature fixup section into the init data area.  It also adds the
initramfs section.

defaults for the advanced kernel config options.

We need __div64_32 exported, and flush_icache_page is now a noop
so it shouldn't be exported.

This simplifies the C code by removing some #ifdefs.
