From 7d3d5ec168f1f40e8547d2a1659670ef222a053b Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 21 Feb 2009 23:41:57 -0800 Subject: [PATCH] etherh: Get working again. Further to a71558d, this is round five of fixes to make etherh work again. As mainline kernels stand, the fixes in b9a9b4b were the wrong approach. The 8390 driver was structured by Al Viro to allow the flexibility required by platforms. lib8390.c contains the core code which drivers explicitly include: - 8390.c includes lib8390.c to provide the standard ISA based driver. - etherh.c includes it with the accessors defined for RiscPC platforms, where it is addressed via the MMIO accessors with a device dependent register spacing. Other platform drivers do something similar. However, b9a9b4b caused the kernel to contain not only the etherh private build of lib8390 (included in etherh.c) but also lib8390.c itself, and referred the new net_device_ops methods to the ISA version. The result of this is is not pretty: Unable to handle kernel paging request at virtual address 12032030 pgd = c8330000 [12032030] *pgd=00000000 Internal error: Oops: 18331805 [#1] Modules linked in: ipv6 CPU: 0 Not tainted (2.6.29-rc3 #167) PC is at do_set_multicast_list+0xd0/0x190 LR is at bitrev32+0x28/0x34 pc : [] lr : [] psr: a0000093 sp : c8321d9c ip : c8321d84 fp : c8321dbc r10: c80c6800 r9 : 00000000 r8 : c80c6b60 r7 : c80c6b80 r6 : cc80c800 r5 : c80c6800 r4 : 00000000 r3 : cc80c80c r2 : 00000004 r1 : 00000007 r0 : e0000000 Flags: NzCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment user ... Fix up b9a9b4b by making etherh's net_device_ops refer to the internal lib8390 functions, and remove the build of the ISA 8390.c driver. Signed-off-by: Russell King Signed-off-by: David S.
