This makes modpost handle MODULE_DEVICE_TABLE(dmi, xxxx).
I had to change the string pointers in the match table to char arrays,
and picked a size of 79 bytes almost at random -- do we need to make it
bigger than that? I was a bit concerned about the 'bloat' this
introduces into the match tables, but they should all be __initdata so
it shouldn't matter too much.(Actually, modpost does go through the relocations and look at most of
them; it wouldn't be impossible to make it handle string pointers -- but
doesn't seem to be worth the effort, since they're __initdata).Signed-off-by: David Woodhouse

Trying to compile the v850 port brings many compile errors, one of them exists
since at least kernel 2.6.19.There also seems to be noone willing to bring this port back into a usable
state.This patch therefore removes the v850 port.
If anyone ever decides to revive the v850 port the code will still be
available from older kernels, and it wouldn't be impossible for the port to
reenter the kernel if it would become actively maintained again.Signed-off-by: Adrian Bunk

Not all device types need a wildcard at the end of their module
aliases. In particular, for i2c module aliases, the trailing wildcard
is not only unneeded, it could also cause the wrong driver to be
loaded.As I2C devices have no IDs, i2c module aliases are simple, arbitrary
device names. For example:$ /sbin/modinfo lm90
filename: /lib/modules/2.6.25-git18/kernel/drivers/hwmon/lm90.ko
author: Jean Delvare
description: LM90/ADM1032 driver
license: GPL
vermagic: 2.6.25-git18 mod_unload
depends: hwmon
alias: i2c:lm90*
alias: i2c:adm1032*
alias: i2c:lm99*
alias: i2c:lm86*
alias: i2c:max6657*
alias: i2c:adt7461*
alias: i2c:max6680*
$This would cause trouble if one I2C chip name matches the beginning of
another I2C chip name and both chips are supported by different
drivers. For example, an i2c device named lm9042 would cause the lm90
driver to be loaded, while it doesn't support that device. This case
has yet to be seen in practice, but still, I'd like to fix it now. The
cleanest fix is to remove the trailing wildcard from i2c module aliases.Here's a patch doing this.
Not all device type aliases need a trailing wildcard, in particular
the i2c aliases don't. Don't add a wildcard by default in do_table(),
instead let each device type handler add it if needed.I have tested types acpi, dmi, eisa, i2c, ide, ieee1394, input, pci,
pcmcia, platform, pnp, scsi, serio, ssb and usb. Other types (ccw, of,
vio, parisc, sdio and virtio) are untested.

The current PNP combined card + devices module aliase can
never ever match anything, because these values are not available
all at the same time to request a module.Instead of adding the combined alias, we add the device id's
all as individual aliases. Device id's are exported by the PNP
bus and can now properly used to request the loading of a
matching module.The module snd-sbawe currently exports aliases, which can never
match anything:
alias: pnp:cCTLXXXXdCTL0045dCTL0022*

Since the devices may have multiple (or none) compatible properties,
the uevent generated internally by the kernel may have multiple
"C..." entries. So the MODALIAS stored in the module must have
wilcard before and after the compatible entry.
Also, if the 'compatible' field is not used for matching, there
will be no 'C' and that must handled as well.The previous code handled all those case incorrectly and it
"mostly" worked ... but not always.Signed-off-by: Sylvain Munaut

Add modalias attribute support for the almost forgotten now EISA bus and
(at least some) EISA-aware modules.The modalias entry looks like (for an 3c509 NIC):
eisa:sTCM5093
and the in-module alias like:
eisa:sTCM5093*
The patch moves struct eisa_device_id declaration from include/linux/eisa.h
to include/linux/mod_devicetable.h (so that the former now #includes the
latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all
drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE
declared), and adds recognision of __mod_eisa_device_table to
scripts/mod/file2alias.c so that proper modules.alias will be generated.There's no support for /lib/modules/$kver/modules.eisamap, as it's not used
by any existing tools, and because with in-kernel modalias mechanism those
maps are obsolete anyway.The rationale for this patch is:
a) to make EISA bus to act as other busses with modalias
support, to unify driver loadingb) to foget about EISA finally - with this patch, kernel
(who still supports EISA) will be the only one who knows
how to choose the necessary drivers for this bus ;)[akpm@osdl.org: fix the kbuild bit]

Add a bus for the adjunct processor interface. Up to 64 devices can
be connect to the ap bus interface, each device with 16 domains. That
makes 1024 message queues. The interface is asynchronous, the answer
to a message sent to a queue needs to be received at some later point
in time. Unfortunately the interface does not provide interrupts when
a message reply is pending. So the ap bus needs to implement some
fancy polling, each active queue is polled once per 1/HZ second or
continuously if an idle cpus exsists and the poll thread is activ
(see poll_thread parameter).The ap bus uses the sysfs path /sys/bus/ap and has two bus attributes,
ap_domain and config_time. The ap_domain selects one of the 16 domains
to be used for this system. This limits the maximum number of ap devices
to 64. The config_time attribute contains the number of seconds between
two ap bus scans to find new devices.The ap bus uses the modalias entries of the form "ap:tN" to autoload
the ap driver for hardware type N. Currently known types are:
3 - PCICC, 4 - PCICA, 5 - PCIXCC, 6 - CEX2A and 7 - CEX2C.Signed-off-by: Cornelia Huck

There is a small but annoying bug in scripts/mod/file2alias.c which causes
it to generate invalid aliases for input devices on 64 bit archs. This causes
joydev.ko to not be automaticly loaded when inserting a joystick, resulting in
a non working joystick (for the average user).In scripts/mod/file2alias.c is the following code for generating the input
aliases:
static void do_input(char *alias,
kernel_ulong_t *arr, unsigned int min, unsigned int max)
{
unsigned int i;for (i = min; i < max; i++)
if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG)))
sprintf(alias + strlen(alias), "%X,*", i);
}On 32 bits systems, this correctly generates "0,*" for the first alias, "8,*"
for the second etc.However on 64 bits it generates: "0,*20,*" resp "8,*28,*" Notice how it adds 20
+ first entry (hex) ! to the list of hex codes, which is 32 more then the first
entry, thus is because the bit test above wraps at 32 bits instead of 64.scripts/mod/file2alias.c, line 379 reads:
if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG)))
That should be:
if (arr[i / BITS_PER_LONG] & (1L << (i%BITS_PER_LONG)))Notice the added 'L' after the 1, otherwise that is an 32 bit int instead of a
64 bit long, and when that int gets shifted >= 32 times, appearantly the number
by which to shift is wrapped at 5 bits ( % 32) causing it to test a bit 32 bits
too low.The patch below makes the nescesarry 1 char change :)

Here's the patch for modalias support for input classes. It uses
comma-separated numbers, and doesn't describe all the potential keys (no
module currently cares, and that would make the strings huge). The
changes to input.h are to move the definitions needed by file2alias
outside __KERNEL__. I chose not to move those definitions to
mod_devicetable.h, because there are so many that it might break compile
of something else in the kernel.The rest is fairly straightforward.
