This adds iomem annotations, cleans up the code, fixes
an oops at unload time, and builds in the wireless
extensions that were not getting enabled due to an
obsolete CONFIG_NET_PCMCIA_RADIO test.

Tested by Jean Tourrilhes, who pointed out the wireless
extensions problem.

Start ecard_task at initialisation time.
Statically initialise ecard wait queue head.

We do not need to check which type of cache we have before
using using the Harvard or von Neumann cache instructions -
the unimplemented instructions are defined to be NOPs.

There were a few places in assembly code in the ppc64 part of the
kernel where we were using the old forms of the compare instruction
(cmp, cmpi, cmpl, cmpli) which don't specify the operand size (word or
doubleword).  These have been accepted for a long time for backward
compatibility with the old POWER architecture (and defaulted to a
32-bit comparison) but are now being rejected by the latest versions
of binutils.  Some of them were actual bugs in that they were on
things which were actually 64-bit values such as pointers (not that
any of them actually caused a problem in practice).

This patch replaces cmp{,l}{,i} with cmp{,l}[wd]{,i} as appropriate.
The original patch was from Segher Boessenkool, slightly modified by
me.

Alan Cox pointed out that the degree symbol in the thermal sensor proc
files that we have on ppc64 cause problems for people using other
locales or UTF-8.  This patch makes them disappear.

Some stuffs in ppc_ksyms.c where still #ifdef CONFIG_PPC_PSERIES, which
is no longer set for PowerMac-only configs. Change them to depend on
CONFIG_PPC_MULTIPLATFORM for now. Later on, a bunch of these will be
just gone since those are mostly deprecated functions and I'll move the
exports close to the actual functions.

Currently hostfs passes the rdev value from stat() on the host as rdev
value to return to stat() on the guest; but we cannot pass rdev as is
because glibc and the kernel disagree about its definition.  So we must
decode it in a major/minor couple with glibc macros and re-encode it in
kernelspace code.

On 2.4 we used force_delete() to make sure inode were not cached, and we then
close the host file when the inode is cleared; when porting to 2.6 the
"force_delete" thing was dropped, and this patch adds a fix for this (by
setting drop_inode = generic_delete_inode).

Search for drop_inode in the 2.6 Documentation/filesystems/vfs.txt for info
about this.

This patch, based on Ken Chen's patch, changes the default 2.5 msec
migration-cutoff value to be based on cache_decay_ticks, which is what
we used for a long time prior the sched-domains code.  (If an
architecture does not set cache_decay_ticks then 2.5 msec is used.)

This causes the following new migration-cutoff values on various SMP
systems:

 x86, variable:

 2-way celeron 466MHz, 128K:        2.5 msec ->  1.0 msec
 2-way/4-way 2.2 GHz P4 Xeon 1MB:   2.5 msec ->  2.0 msec
 8-way P3 700 MHz Xeon 2MB:         2.5 msec ->  6.0 msec

 x64, variable:

 amd64: 2.0 GHz, 1MB:               2.5 msec -> 1.5 msec
 em64t: 3.4 GHz, 1MB:               2.5 msec -> 3.0 msec

 ppc64 [*]:                         2.5 msec -> 2.5 msec (constant)

 ia64:                              2.5 msec -> 10.0 msec (constant)

    [*] ppc64 does not set cache_decay_ticks so we fall back to the
        default.

I believe in light of previous testing we could attempt this for 2.6.9 as
well.  (Note: that the 2.6.9-rc3 patch looks similar but needs to patch
kernel/sched.c.  Note2: this patch is different from Ken's original one.)
