This series has the remaining patches of the AER & DPC TLP Log handling
consolidation and now includes a few minor improvements to the earlier
accepted TLP Logging code.

v6:
- Preserve "AER:"/"DPC:" prefix on the printed TLP line
- New patch to add "AER:" also on other lines of the AER error dump

v5:
- Fix build with AER=y and DPC=n
- Match kerneldoc and function parameter name

v4:
- Added patches:
- Remove EXPORT of pcie_read_tlp_log()
- Moved code to pcie/tlp.c and build only with AER enabled
- Match variables in prototype and function
- int -> unsigned int conversion
- eetlp_prefix_max into own patch
- struct pcie_tlp_log param consistently called "log" within tlp.c
- Moved function prototypes into drivers/pci/pci.h
- Describe AER/DPC differences more clearly in one commit message

v3:
- Small rewording in a commit message

v2:
- Don't add EXPORT()s
- Don't include igxbe changes
- Don't use pr_cont() as it's incompatible with pci_err() and according
to Andy Shevchenko should not be used in the first place

Ilpo Järvinen (8):
PCI: Don't expose pcie_read_tlp_log() outside of PCI subsystem
PCI: Move TLP Log handling to own file
PCI: Make pcie_read_tlp_log() signature same
PCI: Use unsigned int i in pcie_read_tlp_log()
PCI: Store # of supported End-End TLP Prefixes
PCI: Add TLP Prefix reading into pcie_read_tlp_log()
PCI: Create helper to print TLP Header and Prefix Log
PCI/AER: Add prefixes to printouts
