736759ef59 PCI: Add SPDX GPL-2.0+ to replace GPL v2 or later boilerplate
Add SPDX GPL-2.0+ to all PCI files that specified the GPL and allowed
either GPL version 2 or any later version.

Remove the boilerplate GPL version 2 or later language, relying on the
assertion in b24413180f ("License cleanup: add SPDX GPL-2.0 license
identifier to files with no license") that the SPDX identifier may be used
instead of the full boilerplate text.

c7abb2352c PCI: Remove unnecessary messages for memory allocation failures
Per ebfdc40969 ("checkpatch: attempt to find unnecessary 'out of memory'
messages"), when a memory allocation fails, the memory subsystem emits
generic "out of memory" messages (see slab_out_of_memory() for some of this
logging).  Therefore, additional error messages in the caller don't add
much value.

Remove messages that merely report "out of memory".

This preserves some messages that report additional information, e.g.,
allocation failures that mean we drop hotplug events.

This issue was detected by using the Coccinelle software.

93de690176 PCI: Check for PCI_HEADER_TYPE_BRIDGE equality, not bitmask
Bit 7 of the "Header Type" register indicates a multi-function device when
set.  Bits 0-6 contain encoded values, where 0x1 indicates a PCI-PCI
bridge.  It is incorrect to test this as though it were a mask.

For example, while the PCI 3.0 spec only defines values 0x0, 0x1, and 0x2,
it's conceivable that a future spec could define 0x3 to mean something
else; then tests for "(hdr_type & 0x7f) & PCI_HEADER_TYPE_BRIDGE" would
incorrectly succeed for this new 0x3 header type.

Test bits 0-6 of the Header Type for equality with PCI_HEADER_TYPE_BRIDGE.

d648daca11 [PATCH] ibmphp: Use dword accessors for PCI_ROM_ADDRESS
PCI_ROM_ADDRESS is a 32 bit register and as such should be accessed using
pci_bus_{read,write}_config_dword().  A recent audit of drivers/ turned up
several cases of byte- and word-sized accesses.  The harmful ones were fixed
by Linus directly.  This patches up one of the remaining
harmless-but-still-wrong cases caught in the dragnet.

034ecc724c [PATCH] PCI Hotplug ibmphp_pci.c: Fix masking out needed information too early
here is the patch that fixes the bug introduced by my previous patch which
already went into 2.6.12-rc2 and is likely to cause trouble is someone hits
one the else case here by accident.

Using the &= operation before the if statement destroys the information the
if asks for so we always go into the else branch.

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!
