Chen Gang 3f108de96b parisc: memory overflow, 'name' length is too short for using
'path.bc[i]' can be asigned by PCI_SLOT() which can '> 10', so sizeof(6
* "%u:" + "%u" + '\0') may be 21.

Since 'name' length is 20, it may be memory overflow.

And 'path.bc[i]' is 'unsigned char' for printing, we can be sure the
max length of 'name' must be less than 28.

So simplify thinking, we can use 28 instead of 20 directly, and do not
think of whether 'patchc.bc[i]' can '> 100'.

Helge Deller 7246c31e45 parisc: add uevent helper for parisc bus
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.

Kay Sievers 90f671301a parisc: struct device - replace bus_id with dev_name(), dev_set_name()
(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

Panic if we can't register the parisc bus or the root parisc device.
There's no way we can boot without them, so let the user know ASAP.

If we can't register a parisc device, handle the failure gracefully.

Make knapps work with its 64MB gfx card.  I probably just broke another
machine in the process, but assuming 64MB when 64MB aligned is probably
safer than assuming 32MB all the time.

Convert pa_dev->hpa from an unsigned long to a struct resource.
Use insert_resource() instead of request_mem_region().
Request resources at bus walk time instead of driver probe time.
Don't release the resources as we don't have any hotplug parisc_device
support yet.
Add parisc_pathname() to conveniently get the textual representation
of the hwpath used in sysfs.
Inline the remnants of claim_device() into its caller.

I noticed that some of the STI regions weren't showing up in iomem.
Reading the STI spec indicated that all STI devices occupy at least 32MB.
So check for STI HPAs and give them 32MB instead of 4kB.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
