When CONFIG_PROC_FS is unset, include/linux/interrupt.h defines
init_irq_proc() as an empty function.
arch/sparc/kernel/irq_32.c defines this function unconditionally.
Fix the latter so that it only defines this function when CONFIG_PROC_FS
is set.
This fixes the following error:
arch/sparc/kernel/irq_32.c:672: error: redefinition of 'init_irq_proc'
include/linux/interrupt.h:461: error: previous definition of
'init_irq_proc' was here
This was found using randconfig builds.

We need to make asm-offsets.h contents visible for objects built
with userland headers. Instead of creating a symlink, just have the
file with equivalent include (relative to location of header) created
once. That kills the last symlink used in arch/um builds.
Additionally, both generated headers can become dependencies of
archprepare now, killing the misuse of prepare.

Honestly, I can't decide whether to apply this. It really should never
happen in the kernel, since the kernel can guarantee it won't get the
access rights failure (highest privilege level, and can set %sr and
%protid to whatever it wants.)
It really genuinely is a bug that probably should panic the kernel. The
only precedent I can easily see is x86 fixing up a bad iret with a
general protection fault, which is more or less analogous to code 27
here.
On the other hand, taking the exception on a userspace access really
isn't all that critical, and there's fundamentally little reason for the
kernel not to SIGSEGV the process, and continue...
Argh.
(btw, I've instrumented my do_sys_poll with a pile of assertions that
%cr8 << 1 == %sr3 == current->mm.context... let's see if where we're
getting corrupted is deterministic, though, I would guess that it won't
be.)

parisc: add uevent helper for parisc bus
udev device-driver auto detection was failing to work on the GSC bus, since
udev didn't knew wich driver to load due to a missing MODALIAS environment
variable from kernel.
This patch fixes this by adding the MODALIAS environment variable to the
uevent kernel notifications.
Since modalias_show() generated the modalias string already, I splitted this
out and created a new static function make_modalias() which is now used by
modalias_show() and the new parisc_uevent() function.
Tested on 715/64 and c3000.

Create a new __space_to_prot inline to convert the space id (mmu context)
to a protection id. Sadly it doesn't look like the #ifdef can be eliminated
since relying on the compiler to not truncate a bit on
return (ctx >> SPACEID_SHIFT) << 1;
seems a little dodgy.

Since unwind_frame_init_from_blocked_task() may be called from

The Hammerhead platform is built around a AVR32 32-bit microcontroller
from Atmel. It offers versatile peripherals, such as ethernet, usb
device, usb host etc.
The board also incooperates a power supply and is a Power over Ethernet
(PoE) Powered Device (PD).
Additonally, a Cyclone III FPGA from Altera is integrated on the board.
The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two
DDR2 SDRAM interfaces, which will cover even the most exceptional need
of memory bandwidth. Together with the onboard video decoder the board
is ready for video processing.
This patch does include the basic support for the fpga device driver,
but not the device driver itself.

(I did not compile or test it, please let me know, or help fixing
it, if something is wrong with the conversion)
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".
To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.
We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.
We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.
Thanks,
Kay

prom_nextprop() and prom_firstprop() have slightly different calling
conventions in 32 and 64 bit SPARC.
prom_common.c uses a ifdef guard to ensure that these functions are

On 32bit (and sometimes 64bit) and with big kernel modules like xfs or
ipv6 the relocation types R_PARISC_PCREL17F and R_PARISC_PCREL22F may
fail to reach their PLT stub if we only create one big stub array for
all sections at the beginning of the core or init section.
With this patch we now instead add individual PLT stub entries
directly in front of the code sections where the stubs are actually
called. This reduces the distance between the PCREL location and the
stub entry so that the relocations can be fulfilled.
While calculating the final layout of the kernel module in memory, the
kernel module loader calls arch_mod_section_prepend() to request the
to be reserved amount of memory in front of each individual section.
Tested with 32- and 64bit kernels.
