The symbol table on x86-64 starts to have entries that have names
like:

_GLOBAL__sub_I_65535_0___mod_x86cpu_device_table

They are of type STT_FUNCTION and this one had a length of 18.  This
matched the device ID validation logic and it barfed because the
length did not meet the device type's criteria.

--------------------
FATAL: arch/x86/crypto/aesni-intel: sizeof(struct x86cpu_device_id)=16 is not a modulo of the size of section __mod_x86cpu_device_table=18.
Fix definition of struct x86cpu_device_id in mod_devicetable.h
--------------------

These are some kind of compiler tool internal stuff being emitted and
not something we want to inspect in modpost's device ID table
validation code.

So skip the symbol if it is not of type STT_OBJECT.

We currently include commas on both sides of the feature ID in a
modalias, but this prevents the lowest numbered feature of a CPU from
being matched.  Since all feature IDs have the same length, we do not
need to worry about substring matches, so omit commas from the
modalias entirely.

Avoid generating multiple adjacent wildcards when there is no
feature ID to match.

There's a growing number of drivers that support a specific x86 feature
or CPU.  Currently loading these drivers currently on a generic
distribution requires various driver specific hacks and it often
doesn't work.

This patch adds auto probing for drivers based on the x86 cpuid
information, in particular based on vendor/family/model number
and also based on CPUID feature bits.

For example a common issue is not loading the SSE 4.2 accelerated
CRC module: this can significantly lower the performance of BTRFS
which relies on fast CRC.

Another issue is loading the right CPUFREQ driver for the current CPU.
Currently distributions often try all all possible driver until
one sticks, which is not really a good way to do this.

It works with existing udev without any changes. The code
exports the x86 information as a generic string in sysfs
that can be matched by udev's pattern matching.

This scheme does not support numeric ranges, so if you want to
handle e.g. ranges of model numbers they have to be encoded
in ASCII or simply all models or families listed. Fixing
that would require changing udev.

Another issue is that udev will happily load all drivers that match,
there is currently no nice way to stop a specific driver from
being loaded if it's not needed (e.g. if you don't need fast CRC)
But there are not that many cpu specific drivers around and they're
all not that bloated, so this isn't a particularly serious issue.

Originally this patch added the modalias to the normal cpu
sysdevs. However sysdevs don't have all the infrastructure
needed for udev, so it couldn't really autoload drivers.
This patch instead adds the CPU modaliases to the cpuid devices,
which are real devices with full support for udev. This implies
that the cpuid driver has to be loaded to use this.

This patch just adds infrastructure, some driver conversions
in followups.

Thanks to Kay for helping with some sysfs magic.

This reverts commit 5dd7bf59.

Conflicts:

	scripts/mod/file2alias.c

This change is wrong on many levels.  First and foremost, it causes a
regression.  On boot on Assabet, which this patch gives a codec id of
'ucb1x00', it gives:

	ucb1x00 ID not found: 1005

0x1005 is a valid ID for the UCB1300 device.

Secondly, this patch is way over the top in terms of complexity.  The
only device which has been seen to be connected with this MCP code is
the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same
driver.  Adding a match table, requiring the codec string to match the
hardware ID read out of the ID register, etc is completely over the top
when we can just read the hardware ID register.

This means (most) future busses need only have one hunk in their
patch.  Also took the opportunity to check that function matches the
type.

Again, inspired by Alessandro's patch series.

This patch adds the necessary support in file2alias.c to define
suitable aliases based on the amba_id table in AMBA driver modules.

This should be sufficient to allow such modules to be auto-loaded
via udev.  The AMBA bus driver's uevent hotplug code is also
modified to pass an approriate MODALIAS string in the event.

For simplicity, the AMBA ID is treated an an opaque 32-bit numeber.
Module alises use patterns as appropriate to describe the value-
mask pairs described in the driver's amba_id list.

The proposed alias format is (extended regex):

    ^amba:d(HEX){8}$

Where HEX is a single upper-case HEX digit or a pattern (? or []
expression) matching a single upper-case HEX digit, as expected by
udev.

"d" is short for "device", following existing alias naming
conventions for other device types.  This adds some flexibility for
unambiguously extending the alias format in the future by adding
additional leading and trailing fields, if this turns out to be
necessary.

When I added the driver_data field to hv_vmbus_device_id, I forgot to
take into the account how the alias was created, so it would append the
kernel pointer to the end of the alias, which is not correct.

This changes how the hv_vmbus_device_id alias is created to proper
account for the driver_data field.  As no module yet uses this alias, it
is safe to fix this up at this point in the commit stream.

Broadcom has released cards based on a new AMBA-based bus type. From a
programming point of view, this new bus type differs from AMBA and does
not use AMBA common registers. It also differs enough from SSB. We
decided that a new bus driver is needed to keep the code clean.

In its current form, the driver detects devices present on the bus and
registers them in the system. It allows registering BCMA drivers for
specified bus devices and provides them basic operations. The bus driver
itself includes two important bus managing drivers: ChipCommon core
driver and PCI(c) core driver. They are early used to allow correct
initialization.

Currently code is limited to supporting buses on PCI(e) devices, however
the driver is designed to be used also on other hosts. The host
abstraction layer is implemented and already used for PCI(e).

Support for PCI(e) hosts is working and seems to be stable (access to
80211 core was tested successfully on a few devices). We can still
optimize it by using some fixed windows, but this can be done later
without affecting any external code. Windows are just ranges in MMIO
used for accessing cores on the bus.

The sym_is() compares a symbol in an attempt to automatically skip symbol
prefixes.  It does this first by searching the real symbol with the normal
unprefixed symbol.  But then it uses the length of the original symbol to
check the end of the substring instead of the length of the symbol it is
looking for.  On non-prefixed arches, this is effectively the same thing,
so there is no problem.  On prefixed-arches, since this is exceeds by just
one byte, a crash is rare and it is usually a NUL byte anyways.  But every
once in a blue moon, you get the right page alignment and it segfaults.

For example, on the Blackfin arch, sym_is() will be called with the real
symbol "___mod_usb_device_table" as "symbol" when looking for the normal
symbol "__mod_usb_device_table" as "name".  The substring will thus return
one byte into "symbol" and store it into "match".  But then "match" will
be indexed with the length of "symbol" instead of "name" and so we will
exceed the storage.  i.e. the code ends up doing:
	char foo[] = "abc"; return foo[strlen(foo)+1] == '\0';

The current code to generate usb modaliases from usb_device_id assumes
that the device's bcdDevice descriptor will actually be in BCD format.
While this should be a sane assumption, some devices don't follow spec
and just use plain old hex.  This causes drivers for these devices to
generate invalid modalias lines which will never actually match for the
hardware.

The following patch adds hex support for bcdDevice in file2alias.c by
detecting when a driver uses a hex formatted bcdDevice_(lo|hi) and
adjusts the output to hex format accordingly.

Drivers for devices which have bcdDevice conforming to BCD will have no
change in modalias output.  Drivers for devices which don't conform
(i.e. ibmcam) should now generate valid modaliases.

With this patch spi drivers can use standard spi_driver.id_table and
MODULE_DEVICE_TABLE() mechanisms to bind against the devices.  Just like
we do with I2C drivers.

This is useful when a single driver supports several variants of devices
but it is not possible to detect them in run-time (like non-JEDEC chips
probing in drivers/mtd/devices/m25p80.c), and when platform_data usage is
overkill.

This patch also makes life a lot easier on OpenFirmware platforms, since
with OF we extensively use proper device IDs in modaliases.

Now platform_device is being widely used on SoC processors where the
peripherals are attached to the system bus, which is simple enough.

However, silicon IPs for these SoCs are usually shared heavily across
a family of processors, even products from different companies.  This
makes the original simple driver name based matching insufficient, or
simply not straight-forward.

Introduce a module id table for platform devices, and makes it clear
that a platform driver is able to support some shared IP and handle
slight differences across different platforms (by 'driver_data').
Module alias is handled automatically when a MODULE_DEVICE_TABLE()
is defined.

To not disturb the current platform drivers too much, the matched id
entry is recorded and can be retrieved by platform_get_device_id().

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 <khali@linux-fr.org>
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,

With this patch it exports only the device id's, as properly
matchable aliases:
  alias: pnp:dCTL0070*
  alias: pnp:dCTL0045*
  alias: pnp:dCTL0023*
  alias: pnp:dCTL0044*
  alias: pnp:dCTL0022*
  alias: pnp:dCTL0042*
  alias: pnp:dCTL0041*
  alias: pnp:dCTL0021*
  alias: pnp:dCTL0031*

Now, the exported value of the PNP bus can be used to autoload
a matching module:
  $ modprobe --first-time -n -v pnp:dCTL0045

The module alias support in the kernel have a consistency
check where it is checked that the size of a structure
in the kernel and on the build host are the same.
For cross builds this check does not make sense so detect
when we do cross builds and silently skip the check in these
situations.
This fixes a build bug for a wireless driver when cross building
for arm.

Some crazy devices in the wild have a vendor id of 0x0000.  If we try to
add a module alias with this id, we just can't do it due to a check in
the file2alias.c file.  Change the test to verify that both the vendor
and product ids are 0x0000 to show a real "blank" module alias.

Note, the module-init-tools package also needs to be changed to properly
generate the depmod tables.

This adds the logic to convert the virtio ids into module aliases, and
includes a modalias entry in sysfs and the env var to make probing work.

I2C devices do not have any form of ID as PCI or USB devices have.
No driver uses "MODULE_DEVICE_TABLE(i2c, ...)" because it doesn't
make sense. So we can get rid of struct i2c_device_id and the
associated support code.

Cause modpost to fail if any device id lists are incorrectly terminated,
after reporting the offender.
