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
