[PATCH v1 0/4] powerpc: assorted fixes (gpci, imc, energy, iommu)

Hi,

This series fixes some bugs in powerpc paths found by static review
of linux-next:

  1) hv-gpci sysfs hex formatting can overflow the PAGE_SIZE show
     buffer; switch to sysfs_emit_at() and return -EFBIG
  2) opal-imc debugfs names use char[16] with sprintf for a u32 id
  3) pseries energy walks H_BEST_ENERGY cnt and sprintf()s without
     page bounds
  4) iommu debugfs uses char[10] with %08lx while it_index is
     unsigned long

Patches are independent. Please review.

Thanks,
Xixin Liu
