Only the e500v1/v2 cores have HID1[RXFE] so we should attempt to set or clear this register bit on them. Otherwise we get crashes like: NIP: c0579f84 LR: c006d550 CTR: c0579f84 REGS: ef857ec0 TRAP: 0700 Not tainted (2.6.38.2-00072-gf15ba3c) MSR: 00021002 <ME,CE> CR: 22044022 XER: 00000000 TASK = ef8559c0[1] 'swapper' THREAD: ef856000 CPU: 0 GPR00: c006d538 ef857f70 ef8559c0 00000000 00000004 00000000 00000000 00000000 GPR08: c0590000 c30170a8 00000000 c30170a8 00000001 0fffe000 00000000 00000000 GPR16: 00000000 7ffa0e60 00000000 00000000 7ffb0bd8 7ff3b844 c05be000 00000000 GPR24: 00000000 00000000 c05c28b0 c0579fac 00000000 00029002 00000000 c0579f84 NIP [c0579f84] mpc85xx_mc_clear_rfxe+0x0/0x28 LR [c006d550] on_each_cpu+0x34/0x50 Call Trace: [ef857f70] [c006d538] on_each_cpu+0x1c/0x50 (unreliable) [ef857f90] [c057a070] mpc85xx_mc_init+0xc4/0xdc [ef857fa0] [c0001cd4] do_one_initcall+0x34/0x1a8 [ef857fd0] [c055d9d8] kernel_init+0x17c/0x218 [ef857ff0] [c000cda4] kernel_thread+0x4c/0x68 Instruction dump: 40be0018 3c60c052 3863c70c 4be9baad 3be0ffed 4bd7c99d 80010014 7fe3fb78 83e1000c 38210010 7c0803a6 4e800020 <7c11faa6> 54290024 81290008 3d60c06e Oops: Exception in kernel mode, sig: 4 [#2] ---[ end trace 49ff3b8f93efde1a ]--- Also use the HID1_RFXE define rather than a magic number.
