Hello everybody,
this is first set of patches with Microblaze Linux kernel port.
I tried to clean coding style and repair code with sparse.I tried to split patches to the smallest parts as were possible.
Please be patient with incorrect division - it was a lot of patches.I personally feel the biggest pain in header files.
There are no comments in set of patches because I had no energy
write it. I suppose we will discuss more about individual patches.I create pages for this longer process at www.monstr.eu - wiki page.
I will store all patches in my internal git tree till setup public
git server. And on my pages will be published tarballs.Thanks to John Williams and Steve Neuendorffer for help
with clarification of individual patches.Have a fun,
Michal Simek

This looks really ugly. PAGE_OFFSET is usually a macro.
I looked in patch 29/52 where PAGE_OFFSET is defined (unsigned int
PAGE_OFFSET), which got me wondered: PAGE_OFFSET can be a runtime
variable when it is a constant on most other arches?That being said, I'd use
#define PAGE_OFFSET __page_offset
in some header file and in the .c file:
unsigned int __page_offset;
EXPORT_SYMBOL(__page_offset);that is how arch-frv and -uml seem to do it.

Operator precedence makes it possible; you could omit a lot of () in the code.
(Also try checkpatch.pl to get to know of other style 'errors')

Please, no such filenames in files. It is redundant and hard to keep
'register' is a relict from 30 years ago. Compilers likely ignore it
Of course not, because (char *)d is not an lvalue - and if you ask
me, it is ambiguous and bogus code.Assuming 'd' was int*, d++ would cause it to be incremented by 4.
If you incremented 'd' with char* semantics, it would be incremented
by 1. But since 'd' is still int*, you now have an unaligned pointer,
which is a problem in itself. We do not need more pitfalls than CYou will be wanting to use unsigned long since you are working with
