[PATCH 3.12 17/72] powerpc/powernv: Use CPU-endian PEST in pnv_pci_dump_p7ioc_diag_data()

[Jiri Slaby]

From: Gavin Shan <gwshan@xxxxxxxxxxxxxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 5adaf8629b193f185ca5a1665b9e777a0579f518 upstream.

This fixes the warnings reported from sparse:

  pci.c:312:33: warning: restricted __be64 degrades to integer
  pci.c:313:33: warning: restricted __be64 degrades to integer

Fixes: cee72d5bb489 ("powerpc/powernv: Display diag data on p7ioc EEH errors")
