[PATCH v8 0/7] PCI: Consolidate TLP Log reading and printing

[Ilpo Järvinen]

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.

v8:
- Added missing parameter to kerneldoc.
- Dropped last patch due to conflict with the pci_printk() cleanup
  series (will move the patch into that series).

v7:
- Explain in commit message reasoning why eetlp_prefix_max stores Max
  End-End TLP Prefixes value instead of limiting it by the bridge/RP
  imposed limits
- Take account TLP Prefix Log Present flag.
- Align PCI_ERR_CAP_* flags in pci_regs.h
- Add EE_PREFIX_STR define to be able to take its sizeof() for output
  char[] sizing.

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 (7):
  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
