[PATCH] uml: s390 preparation, sighandler interface abstraction
s390 passes parameters in registers. So the only safe way to find out the
address of signal context, error-address and error-type (trap_no), which are
passed to signal handlers as parameters, is to declare these parameters.
So I inserted an subarch-specific macro which holds the declaration of
parameters for signal handlers.

[PATCH] uml: s390 preparation, checksumming done in arch code
Checksum handling largely depends on the subarch.
Thus, I renamed i386 arch_csum_partial in arch/um/sys-i386/checksum.S back to
csum_partial, removed csum_partial from arch/um/kernel/checksum.c and shifted
EXPORT_SYMBOL(csum_partial) to arch/um/sys-i386/ksyms.c.
Then, csum_partial_copy_to and csum_partial_copy_from were shifted from
arch/um/kernel/checksum.c to arch/um/include/sysdep-i386/checksum.h and
inserted in the calling functions csum_partial_copy_from_user() and
csum_and_copy_to_user().

[PATCH] uml: S390 preparation, abstract host page fault data
This patch removes the arch-specific fault/trap-infos from thread and
skas-regs.
It adds a new struct faultinfo, that is arch-specific defined in
sysdep/faultinfo.h.
The structure is inserted in thread.arch and thread.regs.skas and
thread.regs.tt
Now, segv and other trap-handlers can copy the contents from regs.X.faultinfo
to thread.arch.faultinfo with one simple assignment.
Also, the number of macros necessary is reduced to
FAULT_ADDRESS(struct faultinfo)
extracts the faulting address from faultinfo
FAULT_WRITE(struct faultinfo)
extracts the "is_write" flag
SEGV_IS_FIXABLE(struct faultinfo)
is true for the fixable segvs, i.e. (TRAP == 14)
on i386
UPT_FAULTINFO(regs)
result is (struct faultinfo *) to the faultinfo
in regs->skas.faultinfo
GET_FAULTINFO_FROM_SC(struct faultinfo, struct sigcontext *)
copies the relevant parts of the sigcontext to
struct faultinfo.
On SIGSEGV, call user_signal() instead of handle_segv(), if the architecture
provides the information needed in PTRACE_FAULTINFO, or if PTRACE_FAULTINFO is
missing, because segv-stub will provide the info.
The benefit of the change is, that in case of a non-fixable SIGSEGV, we can
give user processes a SIGSEGV, instead of possibly looping on pagefault
handling.
Since handle_segv() sikked arch_fixup() implicitly by passing ip==0 to segv(),
I changed segv() to call arch_fixup() only, if !is_user.

[PATCH] x86_64: make string func definition work as intended
In include/asm-x86_64/string.h there are such comments:
/* Use C out of line version for memcmp */
#define memcmp __builtin_memcmp
int memcmp(const void * cs,const void * ct,size_t count);
This would mean that if the compiler does not decide to use __builtin_memcmp,
it emits a call to memcmp to be satisfied by the C out-of-line version in
lib/string.c. What happens is that after preprocessing, in lib/string.i you
may find the definition of "__builtin_strcmp".
Actually, by accident, in the object you will find the definition of strcmp
and such (maybe a trick intended to redirect calls to __builtin_memcmp to the
default memcmp when the definition is not expanded); however, this particular
case is not a documented feature as far as I can see.
Also, the EXPORT_SYMBOL does not work, so it's duplicated in the arch.
I simply added some #undef to lib/string.c and removed the (now duplicated)
exports in x86-64 and UML/x86_64 subarchs (the second ones are introduced by

So, my solution is to instead of just adjusting esp0 that creates an
inconsitent state I adjust where the user-space registers are saved with -8
bytes. This gives us the wanted extra bytes on the start of the stack and
esp0 is now correct. This solves the issues I saw from the original
testcase from Mateusz Berezecki and has survived testing here. I think
this should go into -mm a round or two first however as there might be some
cruft around depending on pt_regs lying on the start of the stack. That
however would have broken with the first change too!
It's actually a 2-line diff but I had to move the comment of why the -8 bytes
are there a few lines up. Thanks to Zwane for helping me with this.

[PATCH] Kconfig i18n support
This patch adds i18n support for make *config, allowing users to have the
config process in their own language.
No printk was harmed in the process, don't worry, so all the bug reports,
kernel messages, etc, remain in english, just the user tools to configure
the kernel are internationalized.
Users not interested in translations can just unset the related LANG,
LC_ALL, etc env variables and have the config process in plain english,
something like:
LANG= make menuconfig
is enough for having the whole config process in english. Or just don't
install any translation file.
Translations for brazilian portuguese are being done by a team of
volunteers at:
http://www.visionflex.inf.br/kernel_ptbr/pmwiki.php/Principal/Traducoes
To start the translation process:
make update-po-config
This will generate the pot template named scripts/kconfig/linux.pot,
copy it to, say, ~/es.po, to start the translation for spanish.
To test your translation, as root issue this command:
msgfmt -o /usr/share/locale/es/LC_MESSAGES/linux.mo ~/es.po
Replace "es" with your language code.
Then execute, for instance:
make menuconfig
The current patch doesn't use any optimization to reduce the size of the
generated .mo file, it is possible to use the config option as a key, but
this doesn't prevent the current patch from being used or the translations
done under the current scheme to be in any way lost if we chose to do any
kind of keying.
Thanks to Fabricio Vaccari for starting the pt_BR (brazilian portuguese)
translation effort, Thiago Maciera for helping me with the gconf.cc (QT
frontent) i18n coding and to all the volunteers that are already working on
the first translation, to pt_BR.
I left the question on whether to ship the translations with the stock kernel
sources to be discussed here, please share your suggestions.

A bunch of drivers use ISA DMA helpers or their equivalents for
platforms that have ISA with different DMA controller (a lot of ARM

CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA
slots, but have on-board devices that pretend to be ISA ones).
New symbol added - ISA_DMA_API. Set when we have functional
enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the
series will add missing dependencies for drivers that need them.
I'm very carefully staying the hell out of the recurring flamefest on
what exactly CONFIG_ISA would mean in ideal world - added symbol has a
well-defined meaning and for now I really want to treat it as completely

[PATCH] PCI: fix up word-aligned 16-bit PCI config access through sysfs
This patch adds the possibility to do word-aligned 16-bit atomic PCI
configuration space accesses via the sysfs PCI interface. As a result, problems
with Emulex LFPC on IBM PowerPC64 are fixed.
Patch is present in SLES 9 SP1.

fix last piece of this confusion... famous last words.
