Hi,

make gtags for O= kernel builds is currently broken. For example, when doing:

make O=../build/ x86_64_defconfig
make O=../build/ gtags

gtags generates a warning for each kernel source file to be indexed:

make[1]: Entering directory '/home/darwi/build'
GEN gtags
Warning: '/home/darwi/linux/arch/x86/include/asm/qspinlock.h' is out of source tree. ignored.
Warning: '/home/darwi/linux/arch/x86/include/asm/hpet.h' is out of source tree. ignored.
...
Warning: '/home/darwi/linux/virt/lib/irqbypass.c' is out of source tree. ignored.
make[1]: Leaving directory '/home/darwi/build/'

and then generates an empty index:

$ du -hs ~/build/G*
16K /home/darwi/build/GPATH
16K /home/darwi/build/GRTAGS
16K /home/darwi/build/GTAGS

This series includes a proposed fix. After applying it:

$ make O=../build/ gtags
make[1]: Entering directory '/home/darwi/build'
GEN gtags
make[1]: Leaving directory '/home/darwi/build'

$ du -hs ~/build/G*
9.1M /home/darwi/build/GPATH
506M /home/darwi/build/GRTAGS
696M /home/darwi/build/GTAGS

The generated files can then be integrated with editors or IDEs as
usual.

Thanks,
