[PATCH] via-rhine: references __init code during resume

Fix __init section usage:
rhine_resume calls enable_mmio, so latter cannot be __devinit;
Error: ./drivers/net/via-rhine.o .text refers to 0000000000000925 R_X86_64_PC32
.init.text+0xfffffffffffffffc

[PATCH] amd8111e: Add support for ppc64 eval board

This patch adds a few memory barriers, cleans up a little bit the
use of the "status" field in the rx & tx routines, and adds probing
for the external PHY to the driver.

[PATCH] amd8111e: Fix identation of amd8111e_rx_poll()

This patch does an indentation fix to amd8111e_rx_poll() which was
incorrectly shifting left in the middle of a while() loop, thus
rendering the function difficult to read. There is no actual code
change.
