Trying to compile drivers/net/ixgb/ixgb_main.c in 2.6.8-rc1-mm1 using
gcc 3.4 results in compile errors starting with the following:
<-- snip -->
...
CC drivers/net/ixgb/ixgb_main.o
drivers/net/ixgb/ixgb_main.c: In function `ixgb_up':
drivers/net/ixgb/ixgb_main.c:86: sorry, unimplemented: inlining failed
in call to 'ixgb_irq_enable': function body not available
drivers/net/ixgb/ixgb_main.c:234: sorry, unimplemented: called from here
make[3]: *** [drivers/net/ixgb/ixgb_main.o] Error 1
<-- snip -->
The patch below moves some inlined functions above the place where they
are called the first time.
An alternative approach would be to remove the inlines.
