2.5.68-bk11: .text.exit errors in .altinstructions

[Adrian Bunk]

Hi Andi,

I'm getting the following .text.exit errors in 2.5.68-bk11 (kernel 
compiled with gcc 2.95 for a K6):

<--  snip  -->

./drivers/hotplug/pci_hotplug.o(.altinstructions+0xa8): undefined 
reference to `local symbols in discarded section .exit.text'
./drivers/hotplug/pci_hotplug.o(.altinstructions+0xb4): undefined 
reference to `local symbols in discarded section .exit.text'
./drivers/hotplug/cpci_hotplug_core.o(.altinstructions+0x90): undefined

./drivers/hotplug/built-in.o(.altinstructions+0xa8): undefined reference 
to `local symbols in discarded section .exit.text'
./drivers/hotplug/built-in.o(.altinstructions+0xb4): more undefined 
references to `local symbols in discarded section .exit.text' follow

<--  snip  -->

The strange thing is that all errors are in .altinstructions, the files 
seem to be OK, and the problem wasn't present in earlier kernel 
versions.

Disassembled .altinstructions from drivers/hotplug/cpci_hotplug_core.o:
