I was hoping other non pdaxrom developers would read this too :-)

I was actually working with 2.6.22.9 as of 2 weeks ago
I may give 2.6.23 try this weekend and determine if it will be the NEW official kernel

That's what you'll get:
CODE
  CC      arch/arm/common/sharpsl_pm.o
arch/arm/common/sharpsl_pm.c:785: ошибка: ‘pm_valid_only_mem’ undeclared here (not in a function)
make[1]: *** [arch/arm/common/sharpsl_pm.o] Ошибка 1


It have some pxa fixes, some patches (OZ's) now in mainline, some needs a bit modification (pxa-overlay for example). I don't know what should I do with this sharpsl_pm problem...

P.S. I've attached patches that I was using.

Have you tried looking to see if that function is in some other file? You could just add an include then and it should be OK, assuming it's just the one thing.

Not yet, I'll do it today. By the way - there was some changes in function names since 2.6.22

P.S. I've do some googling and it looks like pm_valid_only_mem is now suspend_valid_only_mem

Added:
Yup. pm_valid_only_mem is now suspend_valid_only_mem

I had a close look at the changelog and things like this have been happening (this is just the first one of intrest to the type of problem that Civil was hitting):
commit b750a09385d7c464113ae8915e63541a163fbac8
Author: Eric Miao <eric.y.miao@gmail.com>
Date: Wed Jul 18 11:40:13 2007 +0100

[ARM] 4489/1: pxa: split pxa_cpu_suspend to processor specific ones

1. split pxa_cpu_suspend to pxa25x_cpu_suspend and pxa27x_cpu_suspend
and make pxa25x_cpu_pm_enter() and pxa27x_cpu_pm_enter() to invoke
the corresponding _suspend functions, thus remove all those ugly
#ifdef .. #endif out of sleep.S

2. move the declarations of those suspend functions to pm.h

note: this is not a clean enough solution until all the pxa25x and
pxa27x specific part is further removed out of sleep.S, sleep.S is
supposed to contain generic code only

As I remember there was also cleanup on PM so the old patches need to be carefully adjusted by also looking at the functions used and even may require targeting different files if pxa specific code was moved out of the generic code.

Here is a specific chunk of the changelog concerning PM:
[ARM] 4488/1: pxa: move pxa25x/pxa27x specific code out of pm.c

1. introduce a structure pxa_cpu_pm_fns for pxa25x/pxa27x specific
operations as follows:

struct pxa_cpu_pm_fns {
int save_size;
void (*save)(unsigned long *);
void (*restore)(unsigned long *);
int (*valid)(suspend_state_t state);
void (*enter)(suspend_state_t state);
}

2. processor specific registers saving and restoring are performed
by calling the corresponding (*save) and (*restore)

3. pxa_cpu_pm_fns->save_size should be initialized to the required
size for processor specific registers saving, the allocated
memory address will be passed to (*save) and (*restore)

memory allocation happens early in pxa_pm_init(), and save_size
should be assigned prior to this (which is usually true, since
pxa_pm_init() happens in device_initcall()

4. there're some redundancies for those SLEEP_SAVE_XXX and related
macros, will be fixed later, one way possible is for the system
devices to handle the specific registers saving and restoring

BTW: 2.6.23.1 is out too but the changelog has nothing intresting for ARM.
