Subject: Compile error with 2.6.34-rc5+

Hi,

While compiling current git HEAD on one of my boxes I got a compile error.
Current head is at 1ef6ce7a340f9ed139a73147ff9cf7ad56889414 and the
compile error is

drivers/built-in.o: In function `raid5_compute_sector':
raid5.c:(.text+0x85a36): undefined reference to `__umoddi3'
raid5.c:(.text+0x85a67): undefined reference to `__umoddi3'
raid5.c:(.text+0x85a9c): undefined reference to `__umoddi3'
raid5.c:(.text+0x85acd): undefined reference to `__umoddi3'
raid5.c:(.text+0x85b23): undefined reference to `__umoddi3'
drivers/built-in.o:raid5.c:(.text+0x85b54): more undefined references to
`__umoddi3' follow

The config file was taken straight from a -rc4 kernel and make oldconfig
was run before that.
This runs on/is compiled for a 32bit Pentium IV system so I wonder why umoddi3 is being used.

Kind regards,
Michael

This indeed is the same problem. I checked the archives before sending
the mail but apparently missed that one. Thank you for the information.
