765ee51f9a Revert "EISA: Initialize device before its resources"
This reverts commit 26abfeed43.

In the eisa_probe() force_probe path, if we were unable to request slot
resources (e.g., [io 0x800-0x8ff]), we skipped the slot with "Cannot
allocate resource for EISA slot %d" before reading the EISA signature in
eisa_init_device().

Commit 26abfeed43 moved eisa_init_device() earlier, so we tried to read
the EISA signature before requesting the slot resources, and this caused
hangs during boot.

26abfeed43 EISA: Initialize device before its resources
Move eisa_init_device() before eisa_request_resources() so the device
name is set before we set up its resources.  That way we can print
better messages.

Previously edev->res[i].name was set to NULL in eisa_request_resources(),
then filled in by eisa_init_device().  Now it is filled in by
eisa_init_device() first, and we don't want to clear it out later in
eisa_request_resources().

c5fb301ae8 EISA/PCI: Init EISA early, before PNP
Matthew reported kernels fail the pci_eisa probe and are later successful
with the virtual_eisa_root_init force probe without slot0.

The reason for that is: PNP probing is before pci_eisa_init gets called
as pci_eisa_init is called via pci_driver.

pnp 00:0f has 0xc80 - 0xc84 reserved.
[    9.700409] pnp 00:0f: [io  0x0c80-0x0c84]

so eisa_probe will fail from pci_eisa_init
				==>eisa_root_register
					==>eisa_probe path.
as force_probe is not set in pci_eisa_root, it will bail early when
slot0 is not probed and initialized.

Try to use subsys_initcall_sync instead, and will keep following sequence:
	pci_subsys_init
	pci_eisa_init_early
	pnpacpi_init/isapnp_init

After this patch EISA can be initialized properly, and PNP overlapping
resource will not be reserved.
[   10.104434] system 00:0f: [io  0x0c80-0x0c84] could not be reserved

2cfda637e2 EISA/PCI: Fix bus res reference
Matthew found that 3.8.3 is having problems with an old (ancient)
PCI-to-EISA bridge, the Intel 82375. It worked with the 3.2 kernel.
He identified the 82375, but doesn't assign the struct resource *res
pointer inside the struct eisa_root_device, and panics.

pci_eisa_init() was using bus->resource[] directly instead of
pci_bus_resource_n().  The bus->resource[] array is a PCI-internal
implementation detail, and after commit 45ca9e97 (PCI: add helpers for
building PCI bus resource lists) and commit 0efd5aab (PCI: add struct
pci_host_bridge_window with CPU/bus address offset), bus->resource[] is not
used for PCI root buses any more.

The 82375 is a subtractive-decode PCI device, so handle it the same
way we handle PCI-PCI bridges in subtractive-decode mode in
pci_read_bridge_bases().

82de9a0cc3 eisa/pci_eisa.c: fix BUG introduced by 005bdad7b8
While `pci_eisa_driver' still refer `pci_eisa_init', the .probe() function
should not be called after init memory release, as pointed out by commit
74b9a297. The structure is still referenced in the drivers subsystem, and can
be accesseed through sysfs, so the modpost warning is a false positive. Mark
it as such.

In the same time, the warning referenced in 005bdad7b8 did only mention
`pci_eisa_driver', not `pci_eisa_pci_tbl', so remove its marking.

4b9d0d3b81 eisa: remove driver_data direct access of struct device
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

07563c711f [PATCH] EISA bus MODALIAS attributes support
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 loading

 b) 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 ;)

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!
