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 b24413180f56 ("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.

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!

[PATCH] PCI Hotplug: CPCI update [PATCH] CPCI: update I have finally done some work to update the CompactPCI hotplug driver to fix some of the outstanding issues in 2.6: - Added adapter and latch status ops so that those files will get created by the current PCI hotplug core. This used to not be required, but seems to be now after some of the sysfs rework in the core. - Replaced slot list spinlock with a r/w semaphore to avoid any potential issues with sleeping. This quiets all of the runtime warnings. - Reworked interrupt driven hot extraction handling to remove need for a polling operator for ENUM# status. There are a lot of boards that only have an interrupt driven by ENUM#, so this lowers the bar to entry. - Replaced pci_visit_dev usage with better use of the PCI core functions. The new code is functionally equivalent to the previous code, but the use of pci_enable_device on insert needs to be investigated further, as I need to do some more testing to see if it is still necessary.
