This is a followup to my patches that fixed this all over the tree quite some
time ago. This one went unnoticed for some reason.
TLB handling for CRIS contains local_irq_disable() after local_save_flags().
Turn this into local_irq_save().

Now that the return from alloc_percpu is compatible with the address
of per-cpu vars, it makes sense to hand around the address of per-cpu
variables. To make this sane, we remove the per_cpu__ prefix we used
created to stop people accidentally using these vars directly.
Now we have sparse, we can use that (next patch).
tj: * Updated to convert stuff which were missed by or added after the
original patch.
* Kill per_cpu_var() macro.

Remove the links to architecture and machine dependent directories
(boot, lib, drivers, arch, mach)
The links were created and used mostly from the arch/cris/Makefile,
so why not dispense with them altogether?
Changed $(ARCH) to "cris" in Makefile, it is easier to read this way.
The CRISv32 head.S common files for the kernel and compressed images
needed to be modified to use ifdefs instead of using the now removed
mach link. Since there are only two versions, this is not a huge loss
in readability.
The link to vmlinux.lds.S is also replaced with a merged version
which uses ifdefs to select the correct layout.
System.map before and after are identical.

Inflate requires some dynamic memory allocation very early in the boot
process and this is provided with a set of four functions:
malloc/free/gzip_mark/gzip_release.
The old inflate code used a mark/release strategy rather than implement
free. This new version instead keeps a count on the number of outstanding
allocations and when it hits zero, it resets the malloc arena.
This allows removing all the mark and release implementations and unifying
all the malloc/free implementations.
The architecture-dependent code must define two addresses:
- free_mem_ptr, the address of the beginning of the area in which
allocations should be made
- free_mem_end_ptr, the address of the end of the area in which
allocations should be made. If set to 0, then no check is made on
the number of allocations, it just grows as much as needed
The architecture-dependent code can also provide an arch_decomp_wdog()
function call. This function will be called several times during the
decompression process, and allow to notify the watchdog that the system is
still running. If an architecture provides such a call, then it must
define ARCH_HAS_DECOMP_WDOG so that the generic inflate code calls
arch_decomp_wdog().
Work initially done by Matt Mackall, updated to a recent version of the
kernel and improved by me.

free_area_init_node() gets passed in the node id as well as the node
descriptor. This is redundant as the function can trivially get the node
descriptor itself by means of NODE_DATA() and the node's id.
I checked all the users and NODE_DATA() seems to be usable everywhere
from where this function is called.

- Use the normal cross gcc instead of using an elf specific cris toolchain.
This removes the dependency of this second toolchain.
- Use the normal cross objcopy instead of overriding it to use elf-toolchain.
This allows compiling using "CROSS_COMPILE=$CRIS_GCC/cris-axis-linux-gnu-"
instead of just "CROSS_COMPILE=$CRIS_GCC/cris-axis-linux-gnu/bin/"
- Remove redundant rules for compiling, the implicit rules are sufficient.
- Convert the arch/cris/arch-v10/boot/compressed/head.S to format
accepted by the cris-axis-linux-gnu-gcc (registers must be prefixed
with '$', remove explicit underscore on exported symbols)
- Remove a number of unused (and duplicated) prototypes from
arch/cris/arch-v10/boot/compressed/misc.c.
- Correct memcpy and memset return values (actually return them!)

lib/usercopy and uaccess.h
Function __copy_user_zeroing in arch/lib/usercopy.c had the wrong parameter
set as __user, and in include/asm-cris/uaccess.h, it was not set at all for

This will cut the number of warnings quite dramatically when using sparse.

Adrian Bunk reported another compile error with a SVN head GCC:
...

/home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:139:
error: lvalue required as increment operand
...
This is due to the use of the construct:
*((long*)dst)++ = lc;
Which isn't legal since casts don't return an lvalue.
The solution is to import the implementation from newlib,
which is continually autotested together with GCC mainline,
and uses the construct:
*(long *) dst = lc; dst += 4;
Since this is an import of a file from newlib, I'm not touching
the formatting or correcting any checkpatch errors.
As for the earlier fix for memset.c, even if the two files for
CRIS v10 and CRIS v32 are identical at the moment, it might
be possible to tweak the CRIS v32 version.
Thus, I'm not yet folding them into the same file, at least not
until we've done some research on it.

Commit 2f569afd9ced9ebec9a6eb3dbf6f83429be0a7b4
(CONFIG_HIGHPTE vs. sub-page page tables) introduced use of
inc_zone_page_state and dec_zone_page_state in include/linux/mm.h.
Those are defined in include/linux/vmstat.h, but after it includes
mm.h, making it impossible to include vmstat.h since inc_zone_page_state
and dec_zone_page_state then would be undefined.
arch/cris/arch-v10/kernel/time.c does just this, which makes the
CRIS v10 build break with the following error:
...
