[Xen-devel] [PATCH RFC v1] Cleanups + various fixes due to libxl ABI + more logging on errors.



As I am in the process of syncing the 'dev.config' and Xen's internal
cache of the PCI config space I noticed that some oddities
in the code and figured that having them in would be easier
for me (so I don't have to handle 20 odd patches).

These:
 [PATCH RFC 1/6] xen/pt: Update comments with proper function name.
 [PATCH RFC 2/6] xen/pt: Make xen_pt_msi_set_enable static
 [PATCH RFC 3/6] xen/pt: xen_host_pci_config_read returns -errno, not
 [PATCH RFC 4/6] xen: Print and use errno where applicable.

are quite simple.

The two other ones:
 [PATCH RFC 5/6] xen/pt/msi: Add the register value when printing
 [PATCH RFC 6/6] xen: Add backtrace for serious issues.

are more for adding the proper infrastructure to debug in the field
bugs that may come about.
