Trying to compile drivers/net/e1000/e1000_main.c in 2.6.8-rc1-mm1
with gcc 3.4 results in compile errors starting with the following:
<-- snip -->
...
CC drivers/net/e1000/e1000_main.o
drivers/net/e1000/e1000_main.c: In function `e1000_up':
drivers/net/e1000/e1000_main.c:136: sorry, unimplemented: inlining
failed in call to 'e1000_irq_enable': function body not available
drivers/net/e1000/e1000_main.c:274: sorry, unimplemented: called from here
make[3]: *** [drivers/net/e1000/e1000_main.o] Error 1
<-- snip -->
The patch below moves some inlined functions before the place where they
are called the first time.
An alternative approach would be to remove the inlines.
